OFFER TO PURCHASE

all of the outstanding common shares of

IAMGOLD CORPORATION

by GOLDEN STAR RESOURCES LTD.

     Golden Star Resources Ltd. (together with its subsidiaries, “Golden Star,” “we,” “us,” or “our company”) hereby offers to purchase all of the outstanding common shares of IAMGold Corporation. Under the offer, holders of IAMGold shares will be entitled to receive 1.15 common shares of Golden Star for each IAMGold common share. The offer will be open for acceptance until 9:00 p.m. (Toronto time) on July 16, 2004 unless extended or withdrawn. We will pay all the expenses of this offer.

     Our obligation to exchange the Golden Star common shares for IAMGold common shares is subject to the conditions listed under “The Offer — Conditions to the Offer.”

     Our common shares are traded on the American Stock Exchange under the symbol “GSS” and on the Toronto Stock Exchange under the symbol “GSC.” Based on the trading price of the Golden Star and IAMGold shares on the TSX, the offer values each IAMGold shares at Cdn$8.33, representing a premium of 12.8% to the closing trading price of the IAMGold Shares on the TSX on May 27, 2004 (being the last trading day prior to our announcement of the proposed business combination with IAMGold) of Cdn$7.38. Based on the trading price of the Golden Star and IAMGold shares on the AMEX, the offer values each IAMGold share at $6.11 representing a premium of 12.5% to the closing trading price of the IAMGold shares on the AMEX on May 27, 2004 of $5.43. The closing prices of the Golden Star shares on May 27, 2004 on the TSX and the AMEX were Cdn$7.24 and $5.31, respectively. The closing prices of the Golden Star shares on June 8, 2004 on the TSX and the AMEX were Cdn$6.20 and $4.61, respectively.

     Golden Star believes that the proposed business combination resulting from the consummation of the offer to shareholders would be superior to the proposed combination of IAMGold and Wheaton River Minerals Ltd. announced in March 2004.

     References in this prospectus to “$” are to United States dollars. Canadian dollars are indicated by the symbol “Cdn$”.

SUMMARY

      This summary highlights information more fully described elsewhere in this prospectus and may not contain all the information that is important to you. You should read the following summary and the more detailed information about us, the offer, and the common shares provided elsewhere in this prospectus and in the documents incorporated by reference, including the “Risk Factors” section and our consolidated pro forma financial statements and notes. References to “Golden Star,” “we,” “our,” and “us” mean Golden Star Resources Ltd., its predecessors and consolidated subsidiaries, or any one or more of them, as the context requires.

Golden Star Resources Ltd.

      We are an international gold mining and exploration company focused primarily on mining, mining development and exploration in Ghana, West Africa. We own a 90% interest in two properties in Ghana: the Bogoso/ Prestea open pit mine and related properties and the Wassa project. We also own an approximately 61% managing interest in the currently inactive Prestea underground mine in Ghana which is now being explored. We hold interests in gold exploration properties in Ghana, Sierra Leone, Mali, Suriname and French Guiana. Based in Denver, Colorado, we currently employ approximately 1,000 people. The principal executive office of Golden Star is located at 10901 W. Toller Drive, Littleton, Colorado, 80127-6312, U.S.A., telephone number (303) 830-9000. Our registered and records office is located at c/o Koffman Kalef, Suite 1900, 885 West Georgia Street, Vancouver, British Columbia, Canada V6C 3H4.

      Our common shares are listed and posted for trading on the Toronto Stock Exchange, or TSX, under the symbol “GSC” and on the American Stock Exchange, or AMEX, under the symbol “GSS”.

IAMGold Corporation

      IAMGold is a Canadian company engaged primarily in the exploration for, the development and production of, and the creation and acquisition of royalty interests on, mineral resources properties throughout the world. The registered office and principal executive office of IAMGold is located at 220 Bay Street, 5th Floor, Toronto, Ontario, M5J 2W4, Canada, telephone number (416) 360-4710.

      IAMGold’s common shares are listed on the TSX under the symbol “IMG” and on the AMEX under the symbol “IAG”.

The Offer

      We are offering, on the terms and subject to the conditions of the offer, to purchase all of the issued and outstanding common shares of IAMGold, on the basis of 1.15 common shares of Golden Star for each common share of IAMGold. Assuming that all of the IAMGold shares that are issued and outstanding as of June 4, 2004, and all shares issuable upon exercise of IAMGold options that are in the money on that date, are tendered to the offer and that we take up and pay for such shares under the offer, we will issue approximately 171,656,719 Golden Star common shares. We have applied to the TSX and AMEX to list the common shares of Golden Star issued in exchange for common shares of IAMGold in connection with the offer. Listing will be subject to Golden Star fulfilling all the listing requirements of the exchanges.

      Based on the trading price of the Golden Star and IAMGold shares on the TSX, the offer values each IAMGold share at Cdn$8.33, representing a premium of 12.8% to the closing trading price of the IAMGold shares on the TSX on May 27, 2004 (being the last trading day prior to our announcement of the proposed business combination with IAMGold) of Cdn$7.38. The offer represents a premium of 12.0% based on the volume weighted average trading price of the Golden Star and IAMGold shares for the 60 trading days ended May 27, 2004 of Cdn$7.42 and Cdn$7.62, respectively, on the TSX.

      Based on the trading price of the Golden Star and IAMGold shares on the AMEX, the offer values each IAMGold share at $6.11, representing a premium of 12.5% to the closing trading price of the IAMGold shares on AMEX on May 27, 2004 of $5.43. The offer represents a premium of 13.8% based on

Table of Contents

      We believe that the offer to IAMGold shareholders is superior to the proposed combination of IAMGold and Wheaton River Minerals Ltd. announced in March 2004.

      The offer is made only for IAMGold shares and not for any options or other rights to acquire IAMGold shares. Any holder of such securities who wishes to accept the offer must, to the extent permitted by the terms thereof and applicable law, fully exercise such options or other rights before the expiry time in order to obtain a certificate representing IAMGold shares and then deposit those IAMGold shares in accordance with the terms of the offer.

Purpose of the Offer and Acquisition of Remaining Shares

      The purpose of the offer is to enable us to acquire all of the outstanding IAMGold common shares. If we take up and pay for the shares validly deposited under the offer, we currently intend to exercise our statutory right, if available, to acquire all the IAMGold common shares not deposited to the offer or, if such statutory right of acquisition is not available, we currently intend to cause a meeting of IAMGold shareholders to be held to consider an amalgamation, statutory arrangement, capital reorganization or other transaction whereby we will acquire any IAMGold shares not deposited to the offer.

Conditions of the Offer

      We reserve the right to withdraw the offer and not take up and pay for any IAMGold shares deposited under the offer unless all of the conditions of the offer are satisfied or, where permitted, waived. These conditions include, among others, the conditions that (i) not less than 66 2/3% of the IAMGold shares (on a fully-diluted basis) shall have been validly deposited under the offer and not withdrawn at the expiry time; (ii) we have gained access to non-public information about IAMGold and are satisfied as a result of the review thereof that such information does not contain any facts or other information that would result in a Material Adverse Effect (as defined on p. 27 of this prospectus) to IAMGold if the offer were completed or a change, event, occurrence or state of facts that is or would reasonably be expected to be material and adverse to any of the Material Interests (as defined on p. 27 of this prospectus); and (iii) the previously-announced plan of arrangement between IAMGold and Wheaton River Minerals Ltd. shall not have been completed. See “The Offer — Conditions of the Offer” in this prospectus.

Manner and Time for Acceptance

      The offer is open for acceptance until 9:00 p.m. (Toronto, Canada time) on July 16, 2004 or until such later time and date to which the offer may be extended by us at our discretion, unless withdrawn by us.

      The offer may be accepted by shareholders by depositing certificates representing IAMGold shares that are being deposited, together with a duly completed and signed letter of transmittal (printed on blue paper), at the offices of CIBC Mellon Trust Company, as depositary, specified in the letter of transmittal at or before the expiry time of the offer. The offer will be deemed to be accepted only if the depositary has actually received these documents at or before the expiry time of the offer. Shareholders whose shares are registered in the name of a broker, dealer, bank, trust company or other nominee should request their nominee to effect the transaction.

      Shareholders whose certificates for IAMGold shares are not immediately available may use the procedures for guaranteed delivery set forth in the notice of guaranteed delivery (printed on yellow paper).

Payment for Deposited Shares

      If all of the conditions of the offer have been satisfied or, where permitted, waived by us, we will become obligated to take up and pay for the IAMGold shares validly deposited under, and not withdrawn from, the offer within the time periods prescribed by applicable securities laws. Any IAMGold shares

Table of Contents

Right to Withdraw Deposited Shares

      All deposits of IAMGold shares under the offer are irrevocable, except as provided in the offer. The offer permits withdrawal of the shares deposited under the offer at any time before the IAMGold shares are taken up by us and if such shares have not been paid for by us within three business days after having been taken up. The term “business day” means any day of the week other than a Saturday, Sunday or a statutory or civic holiday observed in Toronto, Canada or Denver, Colorado.

Certain Canadian Federal Income Tax Considerations

      A Canadian resident shareholder who holds IAMGold shares as capital property and who sells such shares pursuant to the offer will generally not realize a capital gain or capital loss under the Income Tax Act (Canada), referred to as the “Tax Act,” unless the shareholder elects to recognize a capital gain or capital loss.

      A subsequent acquisition transaction may give rise to either a taxable event or tax deferred exchange of IAMGold shares depending upon the form of the transaction and the consideration offered.

      A shareholder who is not a resident of Canada who disposes of IAMGold shares for our shares pursuant to the offer will generally not be subject to tax in Canada if the IAMGold shares are not taxable Canadian property. See “Certain Canadian Federal Income Tax Considerations.”

Certain U.S. Income Tax Considerations

      We will endeavour to cause the exchange of IAMGold shares pursuant to the offer to be treated as an exchange made pursuant to a reorganization for U.S. income tax purposes. If reorganization treatment applies to the exchange, a U.S. holder who exchanges IAMGold shares and owns, immediately after the exchange, less than 5% of Golden Star (by voting power and value, directly and by attribution) will generally not recognize a capital gain or capital loss for U.S. tax purposes on the receipt of our shares for IAMGold shares, except with respect to cash received in lieu of a fractional share. If reorganization treatment does not apply to the exchange, the U.S. holder will generally be required to recognize a capital gain or loss. See “Certain U.S. Income Tax Considerations.”

Risk Factors

      An investment in Golden Star shares and the business combination with IAMGold are subject to certain risks. Please see “Risk Factors” commencing on page 11.

Depositary

      CIBC Mellon Trust Company is acting as depositary under the offer. The depositary will be responsible for receiving certificates representing deposited IAMGold shares and accompanying letters of transmittal and other documents. The depositary is also responsible for receiving notices of guaranteed delivery, giving notices, if required, and making payment for all IAMGold shares purchased by us under the terms of the offer.

Financial Advisor, Dealer Manager and Information Agent

      BMO Nesbitt Burns Inc. has been retained to act as our financial advisor. In addition, BMO Nesbitt Burns Inc. and Harris Nesbitt Corp., its U.S. affiliate, have been retained to act as dealer manager in connection with the offer. In Canada, BMO Nesbitt Burns Inc. may form a soliciting dealer group comprised of members of the Investment Dealers Association of Canada and members of the stock exchanges in Canada to solicit acceptances of the offer. In addition, Innisfree M & A Incorporated has been retained to act as Information Agent in connection with the offer.

Non-GAAP Financial Measures

      In this prospectus, the terms “total cash cost” and “cash operating cost” are used on a per ounce of gold basis. Total cash cost per ounce is equivalent to mining operations expenses for the period divided by the number of ounces of gold sold during the period. Cash operating cost per ounce is equivalent to total cash cost per ounce, less production royalties. We have included total cash cost and cash operating cost information to provide investors with information about the cost structure of our mining operations. This information differs from measures of performance determined in accordance with GAAP in Canada and in the United States and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. These measures are not necessarily indicative of operating profit or cash flow from operations as determined under GAAP and may not be comparable to similarly titled measures of other companies.

Statements Regarding Forward-Looking Information

      This prospectus, including Annex A and the pro forma consolidated financial statements of Golden Star and some of the information incorporated by reference in this prospectus, contains forward-looking statements, with respect to our financial condition, results of operations, business prospects, plans, objectives, goals, strategies, future events, capital expenditure, and exploration and development efforts. Words such as “anticipates”, “expects”, “intends”, “plans”, “forecasts”, “projects”, “budgets”, “believes”, “seeks”, “estimates”, “could”, “might”, “should”, and similar expressions identify forward-looking statements. Although we believe that our plans, intentions and expectations reflected in these forward-looking statements are reasonable, we cannot be certain that these plans, intentions or expectations will be achieved. Actual results, performance or achievements could differ materially from those contemplated, expressed or implied by the forward-looking statements contained or incorporated by reference in this prospectus. These statements include comments regarding: operations and synergies of the combined company, the establishment and estimates of mineral reserves and mineral resources, production, production commencement dates, productions costs, cash operating costs per ounce, total cash costs per ounce, grade, processing capacity, potential mine life, feasibility studies, development costs, capital and operating expenditures, exploration, the closing of certain transactions including acquisitions and offerings, our expansion plans for Bogoso/Prestea, and the start-up of Wassa.

      The following factors related to this business combination could cause actual results to differ materially from the forward-looking statements: lack of IAMGold shareholder support for the transaction proposed by Golden Star; the business of Golden Star and IAMGold may not be integrated successfully or such integration may be more difficult, time-consuming or costly than expected; and the expected combination benefits from the Golden Star/IAMGold transaction may not be fully realized or realized within the expected time frame. In addition, the factors described below and in the “Risk Factors” in this prospectus may cause actual results to differ:

	•	unexpected changes in business and economic conditions;
	•	significant increases or decreases in gold prices;
	•	changes in interest rates and currency exchange rates;
	•	timing and amount of production;
	•	unanticipated grade changes;
	•	unanticipated recovery rates or production problems;
	•	changes in mining, processing and overhead costs;
	•	changes in metallurgy and processing technology;
	•	access and availability of materials, equipment, supplies, labor and supervision, power and water;
	•	determination of mineral reserves and mineral resources;

RISK FACTORS

      An investment in our common shares involves a high degree of risk. You should consider the following discussion of risks in addition to the other information in this prospectus before tendering and exchanging your shares for our common shares. In addition to historical information, the information in this prospectus contains “forward-looking” statements about our future business and performance. Our actual operating results and financial performance may be very different from what we expect as of the date of this prospectus. The risks below address some of the factors that may affect our future operating results and financial performance. You should also consider the specific risks associated with IAMGold’s business, which are described in IAMGold’s annual report on Form 40-F for the year ended December 31, 2003, and incorporated by reference in this prospectus.

Business Combination Risks

	You may receive Golden Star shares with a market value lower than you expected.

      Golden Star is offering to pay 1.15 Golden Star common shares for each IAMGold common share tendered to the offer and not withdrawn. Based on the closing prices of the IAMGold shares and Golden Star shares on the TSX on May 27, 2004, the date the proposal for a business combination was made, this represents a premium of 13% to IAMGold shareholders. If the market price of Golden Star shares declines and/or if the market price of IAMGold shares increases, the value of the consideration received by IAMGold shareholders will decline as well. For example, during the twelve month period ending on June 8, 2004 (the most recent practicable date prior to the date of this prospectus), the closing price of Golden Star shares on the TSX varied from a low of Cdn$2.81 to a high of Cdn$10.77 and ended that period at Cdn$6.20. Variations like these may occur as a result of changes in, or market perceptions of changes in, the business, operations or prospects of Golden Star, market assessments of the likelihood the offer will be consummated, regulatory considerations, general market and economic conditions and other factors over which Golden Star has no control.

	We have not been given an opportunity to verify the reliability of the information regarding IAMGold included in, or which may have been omitted from, this prospectus.

      In respect of information relating to IAMGold presented in, or due to lack of information omitted from, this prospectus, including all IAMGold financial information, we have relied exclusively upon publicly available information. Any inaccuracy in IAMGold’s publicly available information, or in the information about IAMGold contained in this prospectus, could result in unanticipated liabilities or expenses, increase the cost of integrating the two companies or adversely affect the operational plans of the combined company and its results of operations and financial condition.

	Change of control provisions in IAMGold’s agreements triggered upon the acquisition of IAMGold may lead to adverse consequences.

      IAMGold may be a party to agreements that contain change of control provisions that may be triggered following completion of the offer since Golden Star will hold IAMGold shares representing a majority of the voting rights of IAMGold. The operation of these change of control provisions, if triggered, could result in unanticipated expenses following the consummation of the offer or adversely affect the operations of IAMGold’s joint ventures, which are its primary source of revenue. Unless these change of control provisions are waived by the other party, the operation of any of these provisions could adversely affect the operations and financial condition of the combined company.

	If we acquire IAMGold, IAMGold may be required to pay a break fee of approximately $23 million.

      Under the arrangement agreement between IAMGold and Wheaton River, one or both parties may be required to pay break fees to the other if the arrangement agreement is terminated in certain circumstances. We have agreed with Coeur d’Alene Mines Corporation, who has proposed a business combination with Wheaton River that, if we combine with IAMGold and Coeur d’Alene combines with

	The integration of Golden Star and IAMGold may not occur as planned.

      The offer has been made with the expectation that its successful completion will result in increased earnings and cost savings by taking advantage of the synergies of consolidation and enhanced growth opportunities of the combined company. These anticipated benefits will depend in part on whether Golden Star’s and IAMGold’s operations can be integrated in an efficient and effective manner. Most operational and strategic decisions, and certain staffing decisions, with respect to the combined company have not yet been made. These decisions and the integration of the two companies will present challenges to management, including the integration of systems and personnel of the two companies, and special risks, including possible unanticipated liabilities, unanticipated costs, and the loss of key employees.

	Failure to retain key employees of IAMGold could adversely affect Golden Star after the offer.

      The performance of IAMGold’s operations after the offer could be adversely affected if the combined company cannot retain selected key employees to assist in the integration of IAMGold and Golden Star. If the combined company does not retain certain of IAMGold’s key executives, or if the key executives exercise their rights to terminate their employment agreements following completion of the offer, based on IAMGold’s public disclosure, we believe that IAMGold would be required to pay severance payments totaling approximately Cdn$3 million.

	After the consummation of the offer, IAMGold would become a majority-owned subsidiary of Golden Star and our interest could differ from yours.

      After the consummation of the offer, we would have the power to elect the directors, appoint new management, approve certain actions requiring the approval of IAMGold shareholders, including adopting certain amendments to IAMGold’s constating documents and approving mergers or sales of IAMGold’s assets. In particular, after the consummation of the offer we intend to exercise our statutory right, if available, to acquire all of the IAMGold shares not deposited under the offer, or, if such statutory right of acquisition is not available, to integrate IAMGold and Golden Star, by merger or other transaction whereby the operations of IAMGold and Golden Star are combined. Our interests with respect to IAMGold may differ from those of any remaining minority shareholders.

	The exchange of IAMGold shares pursuant to the offer may be taxable for U.S. holders.

      We will endeavour to cause the exchange of IAMGold shares pursuant to the offer to be treated as an exchange made pursuant to a reorganization for U.S. income tax purposes. If reorganization treatment applies to the exchange, a U.S. holder who exchanges IAMGold shares and owns, immediately after the exchange, less than 5% of Golden Star (by voting power and value, directly and by attribution) will generally not recognize a capital gain or capital loss for U.S. tax purposes on the receipt of Golden Star shares for IAMGold shares, except with respect to cash received in lieu of a fractional share. If reorganization treatment does not apply to the exchange, the U.S. holder will generally be required to recognize a capital gain or loss. There can be no assurance that reorganization treatment will apply to the exchange.

	We have not paid dividends in the past.

      We have not previously paid dividends on our common shares. Although we may pay dividends in the future, there can be no assurance that we will do so.

Financial Risks

	Our business is substantially dependent on gold prices.

      The price of our common shares, our financial results and our exploration, development and mining activities have previously been, and would in the future be, significantly adversely affected by fluctuations in the price of gold. The price of gold is volatile and is affected by numerous factors beyond our control such as the sale or purchase of gold by various central banks and financial institutions, inflation or deflation, fluctuation in the value of the US dollar and foreign currencies, global and regional demand, and the political and economic conditions of major gold-producing countries throughout the world. If gold prices were to decline significantly or for an extended period of time, we might be unable to continue our operations, develop our properties or fulfill our obligations under our agreements with our partners or under our permits and licenses. As a result, we could lose our interest in, or be forced to sell, some of our properties.

      Furthermore, mineral reserve calculations and life-of-mine plans using significantly lower gold prices could result in reduced estimates of mineral reserves and non-reserve mineral resources and in material write-downs of our investment in mining properties and increased amortization, reclamation and closure charges.

	We have recorded substantial losses in the past.

      While we had earnings of $5.2 million in the first quarter of 2004, $22.0 million and $4.9 million in 2003 and 2002, respectively, we reported net losses of $20.6 million in 2001, $14.9 million in 2000, and $24.4 million in 1999. Numerous factors, including declining gold prices, lower than expected ore grades or higher than expected operating costs, and impairment write-offs of mine property and/or exploration property costs, could cause us to become unprofitable in the future. Any future operating losses could make financing our operations and our business strategy, or raising additional capital, difficult or impossible and could materially and adversely affect our operating results and financial condition.

	Our obligations could strain our financial position and impede our business strategy.

      We have total debts and liabilities as of March 31, 2004 of $17.2 million, including $0.8 million payable to financial institutions, $8.5 million of current trade payables and accrued current liabilities and $7.9 million in environmental rehabilitation liabilities. We expect that our indebtedness and other liabilities will increase as a result of our corporate development activities. This indebtedness could have important consequences, including the following:

	•	increasing our vulnerability to general adverse economic and industry conditions;
	•	limiting our ability to obtain additional financing to fund future working capital, capital expenditures, operating and exploration costs and other general corporate requirements;
	•	requiring us to dedicate a significant portion of our cash flow from operations to make debt service payments, which would reduce our ability to fund working capital, capital expenditures, operating and exploration costs and other general corporate requirements;
	•	limiting our flexibility in planning for, or reacting to, changes in our business and the industry; and
	•	placing us at a disadvantage when compared to our competitors that have less debt relative to their market capitalization.

Table of Contents

	Our estimates of mineral reserves and non-reserves could be inaccurate.

      There are numerous uncertainties inherent in estimating proven and probable mineral reserves and measured, indicated and inferred mineral resources, including many factors beyond our control. The accuracy of estimates of mineral reserves and non-reserves is a function of the quantity and quality of available data and of the assumptions made and judgments used in engineering and geological interpretation, which could prove to be unreliable. There can be no assurance that these estimates will be accurate, that mineral reserves and non-reserves figures will be accurate, or that mineral reserves or non-reserves could be mined or processed profitably.

      Fluctuation in gold prices, results of drilling, metallurgical testing and production and the evaluation of mine plans subsequent to the date of any estimate could require revision of the estimate. The volume and grade of mineral reserves mined and processed and recovery rates might not be the same as currently anticipated. Any material reductions in estimates of our mineral reserves and non-reserves, or of our ability to extract these mineral reserves and non-reserves, could have a material adverse effect on our results of operations and financial condition.

	We currently have only one source of significant operational cash flows.

      While we have recently received significant infusions of cash from sales of equity, our only current significant internal source of funds is operational cash flows from Bogoso/Prestea. We expect to commence production at Wassa in the third quarter of 2004, although there can be no assurance that our Wassa production goals will be achieved. Following the combination with IAMGold, we would also have cash flow from IAMGold’s minority interests in the Sadiola, Yatela, Tarkwa and Damang gold mines. There can be no assurance that we will receive distributions or payments from these interests in accordance with our expectations. The anticipated continuing exploration and development of our properties will require significant expenditures over the next several years. We expect that these expenditures will exceed free cash flows generated by Bogoso/Prestea during that period, and therefore we expect to use our excess cash and in the future to require additional outside capital. Lower gold prices during the five years prior to 2002 adversely affected our ability to obtain financing, and recurring lower gold prices could have similar effects in the future. We cannot assure you that in the future we will be able to obtain adequate financing on acceptable terms. If we are unable to obtain additional financing, we might need to delay or indefinitely postpone further exploration and development of our properties, and as a result, we could lose our interest in, or could be forced to sell, some of our properties.

	Implementation of a hedging program might be unsuccessful and incur losses.

      We continue to review whether or not, in light of the potential for gold prices to fall, it would be appropriate to establish a hedging program. To date, we have not decided to implement a hedging program, although we have purchased and expect to continue to purchase puts from time to time, which give us the right to sell gold in the future at a fixed price. The implementation of a hedging program might not, however, protect adequately against declines in the price of gold.

      In addition, although a hedging program could protect us from a decline in the price of gold, it might also prevent us from benefiting fully from price increases. For example, as part of a hedging program, we could be obligated to sell gold at a price lower than the then-current market price. Finally, if unsuccessful, the costs of any hedging program could further deplete our financial resources.

      IAMGold has hedged a portion of its production. Therefore, the combined company may not realize fully the benefits of gold price increases with respect to the ounces hedged.

	We are subject to fluctuations in currency exchange rates, which could materially adversely affect our financial position.

      Our revenues are in U.S. dollars, and we maintain most of our working capital in U.S. dollars or U.S. dollar denominated securities. We convert funds to foreign currencies as payment obligations become

	There could be no opportunity to evaluate the merits or risks of any future acquisition undertaken by us.

      As a key element of our growth strategy, we have stepped up the active pursuit of acquisitions of producing, development and advanced stage exploration properties and companies. Whether or not we are successful in acquiring IAMGold, we plan to continue to actively investigate potential acquisition and merger candidates. Risks related to acquiring and operating acquired properties and companies could have a material adverse effect on our results of operations and financial condition. In addition, to acquire properties and companies, we would use our available cash, incur debt, issue our common shares or other securities, or a combination of any one or more of these. This could limit our flexibility to raise capital, to operate, explore and develop our properties and to make additional acquisitions, and could further dilute and decrease the trading price of our common shares. Acquisition transactions in our business are often initiated and completed over a particularly short period of time. There could be no opportunity for our shareholders to evaluate the merits or risks of any future acquisition undertaken by us except as required by applicable laws and regulations.

	Risks inherent in acquisitions that we might undertake could adversely affect our growth and financial condition.

      We are actively pursuing the acquisition of producing, development and advanced stage exploration properties and companies, and have recently completed the acquisition and joint venture of exploration and development properties in Ghana, Sierra Leone and Mali. From time to time, we might acquire securities of or other interests in companies with which we could enter into acquisitions or other transactions. Acquisition transactions involve inherent risks, including:

	•	accurately assessing the value, strengths, weaknesses, contingent and other liabilities and potential profitability of acquisition candidates;
	•	ability to achieve identified and anticipated operating and financial synergies;
	•	unanticipated costs;
	•	diversion of management attention from existing business;
	•	potential loss of our key employees or the key employees of any business we acquire;
	•	unanticipated changes in business, industry or general economic conditions that affect the assumptions underlying the acquisition; and
	•	decline in the value of acquired properties, companies or securities.

      Any one or more of these factors or other risks could cause us not to realize the benefits anticipated to result from the acquisition of properties or companies, and could have a material adverse effect on our ability to grow and on our financial condition.

	We are subject to litigation risks.

      All industries, including the mining industry, are subject to legal claims, with and without merit. We are involved in various routine legal proceedings, which include labour matters such as unfair termination claims, supplier matters and property issues incidental to our business. We believe it is unlikely that the final outcome of these legal proceedings will have a material adverse effect on our financial position or results of operation. However, defense and settlement costs can be substantial, even with respect to claims that have no merit. Due to the inherent uncertainty of the litigation process, there can be no assurance that the resolution of any particular legal proceeding will not have a material effect on our financial position or results of operations.

Operational Risks

	The technology, capital costs and cost of production of refractory mineral reserves and non-reserves at Bogoso/ Prestea remain subject to a number of uncertainties, including funding uncertainties.

      Based upon the completion of our Bogoso sulfide project feasibility study in 2001 and its subsequent review by a qualified person under National Instrument 43-101, the refractory material at Bogoso/Prestea has been included in our proven and probable mineral reserves. While the sulfide project feasibility study indicated that refractory mineral reserves can be profitably mined and processed at current gold prices, the capital cost to upgrade the Bogoso processing plant with a bio-oxidation or BIOX circuit to process refractory ore, together with related mining equipment, and facilities, is significant. The capital cost of the sulfide project together with our other Bogoso/Prestea expansion plans including capitalized exploration, mine development, and expanding the mining fleet is expected to be approximately $70 million expected to be spent in 2004 and 2005. We cannot assure you that we will have access to capital, whether from internal or external sources, in the required amounts or on acceptable terms. While the processing technology envisioned in the feasibility study has been successfully utilized at other mines, we cannot assure you, in spite of our testing, engineering and analysis that the technology will perform successfully at commercial production levels on the Bogoso/Prestea refractory sulfide ores. Therefore, we cannot assure you that our production estimates can be achieved.

	Completion of our development projects is subject to a number of uncertainties.

      We have completed a feasibility study regarding the development of and commencement of production at Wassa in Ghana using conventional CIL processing techniques and have commenced development of the Wassa mine. We cannot assure you that production will commence when we currently anticipate. We have not yet completed technical studies for the projected $70 million expansion of Bogoso/ Prestea. The IAMGold 18.9% owned Tarkwa mine is currently being expanded. The management of mine development projects and start-up of new operations are complex. We do not have a company history of simultaneously managing two significant development projects and an ongoing operation. We cannot assure you that these development projects will be completed at the cost and on the schedule predicted, or that gold grades and recoveries, production rates or costs anticipated will be achieved. Any development of Wassa and the expansion of Bogoso/ Prestea are subject to all of the risks described in this prospectus, including “Risk Factors — Operational Risks — The development and operation of our mining projects involve numerous uncertainties.”

	Declining gold prices could reduce our estimates of mineral reserves and non-reserves and could result in delays in development until we can make new estimates and determine new potential economic development options under the lower gold price assumptions.

      In addition to adversely affecting our mineral reserve estimates and our financial condition, declining gold prices could impact operations by requiring a reassessment of the feasibility of all or a portion of a particular project. A reassessment might be the result of a management decision or could be required under financing arrangements related to the project. Even if the project is ultimately determined to be

	We are subject to a number of operational hazards that can delay production or result in liability to us.

      Our activities are subject to a number of risks and hazards including:

	•	environmental hazards;
	•	discharge of pollutants or hazardous chemicals;
	•	industrial accidents;
	•	labour disputes and shortages;
	•	supply and shipping problems and delays;
	•	shortage of equipment and contractor availability;
	•	difficulty in applying technology such as biooxidation processing;
	•	unusual or unexpected geological or operating conditions;
	•	slope failures;
	•	cave-ins of underground workings;
	•	failure of pit walls or dams;
	•	fire;
	•	changes in the regulatory environment; and
	•	natural phenomena such as inclement weather conditions, floods and earthquakes.

      These or other occurrences could result in damage to, or destruction of, mineral properties or production facilities, personal injury or death, environmental damage, delays in mining, delayed production, monetary losses and possible legal liability. We could incur liabilities as a result of pollution and other casualties. Satisfying such liabilities could be very costly and could have a material adverse effect on our financial position and results of operations.

	Our mining operations are subject to numerous environmental laws, regulations and permitting requirements that can delay production and adversely affect operating and development costs.

      We cannot assure you that compliance with existing regulations governing the discharge of materials into the environment, or otherwise relating to environmental protection, in the jurisdictions where we have projects will not have a material adverse effect on our exploration activities, results of operations or competitive position. New or expanded regulations, if adopted, could affect the exploration or development of our projects or otherwise have a material adverse effect on our operations.

      A significant portion of our recently acquired Dunkwa property and portions of our Wassa development property as well as some of our exploration properties in Ghana are located within forest reserve areas. Although Dunkwa and Wassa have been identified by the Government of Ghana as eligible for mining permits subject to normal procedures and a site inspection, there can be no assurance that permits for projects in forest reserve areas will be issued in a timely fashion, or at all, or that such permits will not contain special requirements with which it is burdensome or expensive to comply.

      Our relocation of the processing plant to Bondaye near Prestea, conversion of the existing Bogoso/ Prestea processing plant to process refractory sulfide and other activities will require mining and other permits from the Government of Ghana. There can be no assurance that all of these permits will be issued on a timely basis or at all, or that the permits issued will not be subject to requirements or conditions with

      As a result of the foregoing risks, project expenditures, production quantities and rates and cash operating costs, among other things, could be materially and adversely affected and could differ materially from anticipated expenditures, production quantities and rates, and costs. In addition, estimated production dates could be delayed materially. Any such events could materially and adversely affect our business, financial condition, results of operations and cash flows.

	The development and operation of our mining projects involve numerous uncertainties.

      Mine development projects, including our ongoing development at Wassa and anticipated expansion at Bogoso/ Prestea, typically require a number of years and significant expenditures during the development phase before production is possible.

      Development projects are subject to the completion of successful feasibility studies and environmental assessments, issuance of necessary governmental permits and receipt of adequate financing. The economic feasibility of development projects is based on many factors such as:

	•	estimation of mineral reserves and mineral resources;
	•	anticipated metallurgical recovery rates;
	•	environmental considerations and permitting;
	•	future gold prices; and
	•	anticipated capital and operating costs of such projects.

      Our mine development projects could have limited relevant operating history upon which to base estimates of future operating costs and capital requirements. Estimates of proven and probable mineral reserves and operating costs determined in feasibility studies are based on geologic and engineering analyses and might not prove to be accurate.

      Any of the following events, among others, could affect the profitability or economic feasibility of a project:

	•	unanticipated changes in grade and tonnage of ore to be mined and processed;
	•	unanticipated adverse geotechnical and process recovery conditions;
	•	incorrect data on which engineering assumptions are made;
	•	costs of constructing and operating a mine in a specific environment;
	•	availability and cost of processing and refining facilities;
	•	availability of economic sources of power;
	•	adequacy of water supply;
	•	adequate access to the site including competing land uses (such as agriculture and illegal mining);
	•	unanticipated transportation costs;
	•	government regulations (including regulations relating to prices, royalties, duties, taxes, permitting, restrictions on production, quotas on exportation of minerals, as well as the costs of protection of the environment and agricultural lands);
	•	fluctuations in gold prices; and
	•	accidents, labour actions and force majeure events.

      Adverse effects on the operations or further development of a project could also adversely affect our business, financial condition, results of operations and cash flow. Because of these uncertainties, and others identified in “Risk Factors”, there can be no assurance that our production estimates at Bogoso/ Prestea and Wassa can or will be achieved.

	We need to continually obtain additional mineral reserves for gold production.

      Because mines have limited lives based on proven and probable mineral reserves, we must continually replace and expand our mineral reserves as our mines produce gold. At current average production rates, we estimate that Bogoso/Prestea has over ten years of mine life, but our estimates might not be correct and the mine life would be shortened if we expand production. Our ability to maintain or increase our annual production of gold will be dependent in significant part on our ability to bring new mines into production and to expand or extend the life of existing mines.

	Gold exploration is highly speculative, involves substantial expenditures, and is frequently non-productive.

      Gold exploration, including the exploration of the Prestea Underground, involves a high degree of risk and exploration projects are frequently unsuccessful. Few prospects that are explored end up being ultimately developed into producing mines. To the extent that we continue to be involved in gold exploration, the long-term success of our operations will be related to the cost and success of our exploration programs. We cannot assure you that our gold exploration efforts will be successful. The success of gold exploration is determined in part on the following factors:

	•	the identification of potential gold mineralization based on superficial analysis;
	•	the quality of our management and our geological and technical expertise; and
	•	the capital available for exploration and development.

      Substantial expenditures are required to determine if a project has economically mineable mineralization. It could take several years to establish proven and probable mineral reserves and to develop and construct mining and processing facilities. As a result of these uncertainties, we cannot assure you that current and future exploration programs will result in the discovery of mineral reserves, the expansion of our existing mineral reserves and the development of mines.

	We face competition from other mining companies in connection with the acquisition of properties.

      We face strong competition from other mining companies in connection with the acquisition of properties producing, or capable of producing, precious metals. Many of these companies have greater financial resources, operational experience and technical capabilities. As a result of this competition, we might be unable to maintain or acquire attractive mining properties on terms we consider acceptable or at all. Consequently, our revenues, operations and financial condition could be materially adversely affected.

	Title to our mineral properties could be challenged.

      Our policy is to seek to confirm the validity of our rights to title to, or contract rights with respect to, each mineral property in which we have a material interest. However, we cannot guarantee that title to our properties will not be challenged. Title insurance generally is not available, and our ability to ensure that we have obtained secure claim to individual mineral properties or mining concessions could be severely constrained. We might not have conducted surveys of all of the properties in which we hold direct or indirect interests and, therefore, their precise area and location could be in doubt. Accordingly, our mineral properties could be subject to prior unregistered agreements, transfers or claims, and title could be affected by, among other things, undetected defects. In addition, we might be unable to operate our properties as permitted or to enforce our rights with respect to our properties.

	We depend on the services of key executives.

      We are dependent on the services of key executives including our President and Chief Executive Officer and a small number of highly skilled and experienced executives and personnel. Due to the relatively small size of our company, the loss of these persons or our inability to attract and retain additional highly skilled employees could adversely affect the exploration and development of our properties, which could have a material adverse effect on our business and future operations.

      The period of weak gold prices prior to 2002 resulted in the depletion in the number of trained and experienced professionals and managers in our industry. Higher gold prices have resulted in an increased demand for these people, and it could therefore be more difficult to attract or retain such experienced professionals and managers without significantly increasing the cost to Golden Star.

	Our insurance coverage could be insufficient.

      Our business is subject to a number of risks and hazards generally, including:

	•	adverse environmental conditions;
	•	industrial accidents;
	•	labour disputes;
	•	unusual or unexpected geological conditions;
	•	ground or slope failures;
	•	cave-ins;
	•	changes in the regulatory environment; and
	•	natural phenomena such as inclement weather conditions, floods and earthquakes.
	•	political risks including expropriation and civil war

      Such occurrences could result in:

	•	damage to mineral properties or production facilities;
	•	personal injury or death;
	•	loss of legitimate title to properties
	•	environmental damage to our properties or the properties of others;
	•	delays in mining;
	•	monetary losses; and
	•	possible legal liability.

      Although we maintain insurance in amounts that we believe to be reasonable, our insurance might not cover all the potential risks associated with our business. We might also be unable to maintain insurance to cover these risks at economically feasible premiums. Insurance coverage might not continue to be available or might not be adequate to cover any resulting liability. Moreover, insurance against risks such as environmental pollution or other hazards as a result of exploration and production is not generally available to us or to other companies in the mining industry on acceptable terms. We might also become subject to liability for pollution or other hazards which we cannot insure against or which we might elect not to insure against because of premium costs or other reasons. Losses from these events might cause us to incur significant costs that could have a material adverse effect upon our financial performance and results of operations.

Governmental and Regulatory Risks

	As a holding company, limitations on the ability of our operating subsidiaries to make distributions to us could adversely affect the funding of our operations.

      We are a holding company that conducts operations through foreign (principally African) subsidiaries and joint ventures, and substantially all of our assets consist of equity in these entities. Accordingly, any limitation on the transfer of cash or other assets between the parent corporation and these entities, or among these entities, could restrict our ability to fund our operations efficiently. Any such limitations, or the perception that such limitations might exist now or in the future, could have an adverse impact on our valuation and stock price.

	We are subject to changes in the regulatory environment where we operate.

      Our mining operations and exploration activities are subject to extensive regulation governing various matters, including:

	•	licensing
	•	production
	•	taxes
	•	water disposal
	•	toxic substances
	•	mine safety
	•	development and permitting
	•	exports
	•	imports
	•	labour standards
	•	occupational health and safety
	•	environmental protections

      Compliance with these regulations increases the costs of the following:

	•	planning
	•	designing
	•	drilling
	•	operating
	•	developing
	•	constructing
	•	closure and reclamation

      We believe that we are in substantial compliance with current laws and regulations in Ghana and elsewhere. However, these laws and regulations are subject to frequent change and reinterpretation. Due to the substantial increase in mining development during 2003 in Ghana, the Government of Ghana has been reviewing the adequacy of reclamation bonds and guarantees throughout the country and in some cases has requested higher levels of bonding than previously had been required. There can be no assurance that our bonds would not increase. Amendments to current laws and regulations governing operations and activities of mining companies or more stringent implementation or interpretation of these laws and regulations

Table of Contents

      Government regulations limit the proceeds from gold sales that could be withdrawn from Ghana. Changes in regulations that increase these restrictions could have a material adverse impact on us, as Bogoso/ Prestea is currently our only source of internally generated operating cash flows.

	The Government of Ghana has the right to participate in the ownership and control of certain subsidiaries.

      The Government of Ghana currently has a 10% carried interest in our subsidiaries that own our Bogoso/ Prestea mine, Wassa development property and Prestea Underground property. The Government of Ghana also has: (a) the right to acquire up to an additional 20% equity interest in each of these subsidiaries for a price to be determined by agreement or arbitration; (b) the right to acquire a special share or golden share in such subsidiaries at any time for no consideration or such consideration as the Government of Ghana and such subsidiaries might agree; and (c) a pre-emptive right to purchase all gold and other minerals produced by such subsidiaries. We cannot assure you that the Government of Ghana would not seek to exercise one or more of these rights, which could reduce our equity interest. A reduction in our equity interest could reduce our income or cash flows from Bogoso/Prestea and/or reduce our anticipated income or cash flows from Wassa, reducing amounts available to us for reinvestment and adversely affecting our ability to take certain actions.

	We are subject to risks relating to exploration, development and operations in foreign countries.

      Certain laws, regulations and statutory provisions in certain countries in which we have mineral rights could, as they are currently written, have a material negative impact on our ability to develop or operate a commercial mine. For countries where we have exploration or development stage projects, we intend to negotiate mineral agreements with the governments of these countries and seek variances or otherwise be exempted from the provisions of these laws, regulations and/or statutory provisions. We cannot assure you, however, that we will be successful in obtaining mineral agreements or variances or exemptions on commercially acceptable terms.

      Our assets and operations are affected by various political and economic uncertainties, including:

	•	the risks of war, civil unrest, coups or other violent or unexpected changes in government;
	•	political instability and violence;
	•	expropriation and nationalization;
	•	renegotiation or nullification of existing concessions, licenses, permits, and contracts;
	•	illegal mining;
	•	changes in taxation policies;
	•	restrictions on foreign exchange and repatriation; and
	•	changing political conditions, currency controls, and governmental regulations that favor or require the awarding of contracts to local contractors or require foreign contractors to employ citizens of, or purchase supplies from, a particular jurisdiction.

	Illegal mining occurs on our properties, is difficult to control, can disrupt our business and can expose us to liability.

      Artisanal miners illegally work on our properties from time to time, despite the fact that we have hired security personnel to protect our properties. The presence of illegal miners could lead to project delays and disputes regarding the development or operation of commercial gold deposits. The work performed by the illegal miners could cause environmental damage or other damage to our properties, or

	Our activities are subject to complex laws, regulations and accounting standards that can adversely affect operating and development costs, the timing of operations, the ability to operate and financial results.

      Our business, mining operations and exploration and development activities are subject to extensive Canadian, US, Ghanaian and other foreign, federal, state, provincial, territorial and local laws and regulations governing exploration, development, production, exports, taxes, labour standards, waste disposal, protection of the environment, reclamation, historic and cultural resource preservation, mine safety and occupational health, toxic substances, reporting and other matters, as well as accounting standards. Compliance with these laws, regulations and standards or the imposition of new such requirements could adversely affect operating and development costs, the timing of operations, the ability to operate and financial results.

Market Risks

	The market price of our common shares could experience volatility and could decline significantly.

      Our common shares are listed on the American Stock Exchange and the Toronto Stock Exchange. Securities of small-cap companies have experienced substantial volatility in the past, often based on factors unrelated to the financial performance or prospects of the companies involved. These factors include macroeconomic developments in North America and globally and market perceptions of the attractiveness of particular industries. Our share price is also likely to be significantly affected by short-term changes in gold prices or in our financial condition or results of operations as reflected in our quarterly earnings reports. Other factors unrelated to our performance that could have an effect on the price of our common shares include the following:

	•	the extent of analytical coverage available to investors concerning our business could be limited if investment banks with research capabilities do not continue to follow our securities;
	•	the trading volume and general market interest in our securities could affect an investor’s ability to trade significant numbers of common shares;
	•	the relatively small size of the public float will limit the ability of some institutions to invest in our securities; and
	•	a substantial decline in our stock price that persists for a significant period of time could cause our securities to be delisted from the American Stock Exchange and the Toronto Stock Exchange, further reducing market liquidity.

      As a result of any of these factors, the market price of our common shares at any given point in time might not accurately reflect our long-term value. Securities class action litigation often has been brought against companies following periods of volatility in the market price of their securities. We could in the future be the target of similar litigation. Securities litigation could result in substantial costs and damages and divert management’s attention and resources.

	You could have difficulty or be unable to enforce certain civil liabilities on us, certain of our directors and our experts.

      We are a Canadian corporation. Substantially all of our assets are located outside of Canada and the US, and our head office is located in the US. Additionally, a number of our directors and the experts are residents of Canada. Although we have appointed Koffman Kalef, Suite 1900, 885 West Georgia Street, Vancouver, British Columbia and Field LLP, 1900, 350 — 7th Avenue S.W., Calgary, Alberta as our agents for service of process in the Provinces of British Columbia and Alberta, respectively, it might not be possible for investors to collect judgments obtained in Canadian courts predicated on the civil liability

	There may be certain tax risks associated with investments in our company.

      Potential investors that are US taxpayers should consider that we could be considered to be a “passive foreign investment company” (“PFIC”) for federal income tax purposes. Although we believe that we currently are not a PFIC and do not expect to become a PFIC in the near future, the tests for determining PFIC status are dependent upon a number of factors, some of which are beyond our control, and we can not assure you that we would not become a PFIC in the future. If we were deemed to be a PFIC, then a US taxpayer who disposes or is deemed to dispose of our shares at a gain, or who received a so-called “excess distribution” on the shares, generally would be required to treat such gain or excess distribution as ordinary income and pay an interest charge on a portion of the gain or distribution unless the taxpayer makes a timely qualified electing fund election (a “QEF” election). A US taxpayer who makes a QEF election generally must report on a current basis his or her share of any of our ordinary earnings and net capital gain for any taxable year in which we are a PFIC, whether or not we distribute those earnings. Special estate tax rules could be applicable to our shares if we are classified as a PFIC for income tax purposes.

	Future sales of our common shares by our existing shareholders could decrease the trading price of the common shares.

      Sales of a large number of our common shares in the public markets, or the potential for such sales, could decrease the trading price of our common shares and could impair our ability to raise capital through future sales of our common shares. We completed sales of units, comprised of common shares and warrants, in January, July and December 2002 and February 2003 and sales of common shares in August, October, and December 2003, all but the December 2003 offering at prices significantly less than the current market price of our common shares. Accordingly, a significant number of our shareholders have an investment profit in our securities that they could seek to liquidate. Substantially all of our common shares not held by affiliates can be resold without material restriction in the US and Canada.

	The existence of outstanding rights to purchase common shares could impair our ability to raise capital.

      As of June 4, 2004 approximately 18.2 million common shares are issuable on exercise of warrants, options or other rights to purchase common shares at prices ranging from Cdn$1.02 to Cdn$9.07. During the life of the warrants, options and other rights, the holders are given an opportunity to profit from a rise in the market price of our common shares with a resulting dilution in the interest of the other shareholders. Our ability to obtain additional financing during the period such rights are outstanding could be adversely affected, and the existence of the rights could have an adverse effect on the price of our common shares. The holders of the warrants, options and other rights can be expected to exercise them at a time when we would, in all likelihood, be able to obtain any needed capital by new offering of securities on terms more favorable than those provided by the outstanding rights.

	(i) we will have been provided with, or been given access to, in a timely manner, all non-public information relating to IAMGold, including without limitation a true and complete copy of the disclosure letter of IAMGold delivered to Wheaton River Minerals Ltd. pursuant to their arrangement agreement and each of the joint venture/shareholder agreements (including all amendments, supplements and modifications thereto) with respect to each of the Material Interests, and we will be satisfied upon completion of our review of such documents and upon the advice of our legal counsel, that such documents do not contain any facts or other information that would result in a Material Adverse Effect on IAMGold if the offer were completed or a change, event, occurrence or state of facts that is or would reasonably be expected to be material and adverse to any of the Material Interests, either individually or collectively, whether or not the offer were completed;
	(j) the offer, if completed, shall not trigger any Material Adverse Effect on IAMGold;
	(k) the IAMGold shareholders shall not have approved the resolution authorizing the issuance of additional shares of IAMGold to be presented at the IAMGold annual and special meeting of shareholders scheduled to be held on June 8, 2004, as it may be adjourned or postponed and the proposed arrangement between IAMGold and Wheaton River, pursuant to the arrangement agreement dated April 23, 2004, as amended and restated on April 29, 2004, shall not have been completed and the arrangement agreement shall have been terminated;
	(l) we shall not have become aware of any untrue statement of a material fact, or an omission to state a material fact that is required to be stated or that is necessary to make a statement not misleading in the light of the circumstances in which it was made and at the date it was made (after giving effect to all subsequent filings in relation to all matters covered in earlier filings), in any document filed by or on behalf of IAMGold with any regulatory authority in Canada or elsewhere.

      Appropriate Approvals means those sanctions, rulings, consents, orders, exemptions, permits and other approvals (including the lapse, without objection, of a prescribed time under a statute or regulation that states that a transaction may be implemented if a prescribed time lapses following the giving of notice without an objection being made) of Governmental Entities or approvals of shareholders of Golden Star or IAMGold required in connection with the consummation of the offer;

      Governmental Entity means (a) any multinational, federal, provincial, state, regional, municipal, local or other government, governmental or public department, central bank, court, tribunal, arbitral body, commission, board, bureau or agency, domestic or foreign; (b) any subdivision, agent, commission, board, or authority of any of the foregoing; (c) any self-regulatory authority or any of the AMEX or the TSX; or (d) any quasi-governmental or private body exercising any regulatory, expropriation or taxing authority under or for the account of any of the foregoing; and

      The foregoing conditions are for our exclusive benefit and may be asserted by us regardless of the circumstances giving rise to any such condition. We may, in our sole discretion, waive any of the foregoing conditions, in whole or in part, at any time and from time to time, without prejudice to any other rights which we may have. The failure by us at any time to exercise any of the foregoing rights will not be deemed to be a waiver of any such right and each such right shall be deemed to be an ongoing right which may be asserted at any time and from time to time provided that all of the conditions, other than those involving the receipt of Appropriate Approvals, are satisfied or, where permitted, waived by us prior to the expiry date.

      Any waiver of a condition or the withdrawal of the offer shall be effective upon written notice or other communication confirmed in writing by us to that effect to the depositary at its principal office in Toronto. After we give any such notice, we will make a public announcement of the waiver or withdrawal, shall cause the depositary, if required by law, as soon as practicable thereafter to notify the IAMGold shareholders in the manner set forth under “Notice and Delivery” below and shall provide a copy of such notice to the TSX and the AMEX. Any notice of waiver will be deemed to have been given and to be effective on the day on which it is delivered or otherwise communicated to the depositary at its principal office in Toronto. In the event of any waiver, all IAMGold shares deposited previously and not taken up or withdrawn will remain subject to the offer and may be accepted for purchase by us in accordance with the terms of the offer. If the offer is withdrawn, we will not be obligated to take up or pay for any IAMGold shares deposited under the offer and the depositary will promptly return all certificates for deposited IAMGold shares to the parties by whom they were deposited in acceptance of the offer.

Purpose of the Offer

      The purpose of the offer is to enable us to acquire beneficial ownership of all of the IAMGold shares. The effect of the offer is to give you the opportunity to receive our common shares in exchange for your IAMGold shares at the ratio of 1.15 of our common shares for each IAMGold common share. This consideration represents a 12.8% premium over the Cdn$7.38 per share closing price of the IAMGold

Table of Contents

      If we take up and pay for the IAMGold shares validly deposited under the offer, we intend to exercise our statutory right, if available, to acquire all the IAMGold shares not deposited under the offer or, if such statutory right of acquisition is not available, we intend to cause a meeting of IAMGold shareholders to be held to consider an amalgamation, statutory arrangement, capital reorganization or other transaction whereby we will acquire any IAMGold shares not deposited under the offer.

Payment for Deposited IAMGold Shares

      If all of the conditions of the offer have been fulfilled or, where permitted, waived at the expiry time, we will become obligated to take up and pay for the IAMGold shares deposited and not withdrawn under the offer no later than 10 days from the expiry date, and to pay for the IAMGold shares taken up as soon as possible, but in any event not later than three business days after taking up the IAMGold shares. In accordance with applicable law, we will take up and pay for IAMGold shares deposited under the offer after the date on which we first take up IAMGold shares deposited under the offer not later than 10 days after the deposit of IAMGold shares.

      We will be deemed to have taken up and accepted for payment IAMGold shares validly deposited and not withdrawn under the offer if, as and when we give written notice or other communication confirmed in writing to the depositary to that effect.

      We will pay for IAMGold shares validly deposited and not withdrawn under the offer by providing the depositary with sufficient certificates for our shares to be exchanged for the IAMGold shares and funds to pay for fractional Golden Star shares otherwise issuable, if any, for transmittal to persons depositing IAMGold shares under the offer. Under no circumstances will interest accrue or be paid on our shares or cash for fractional shares by us or the depositary, regardless of any delay in making such payment. Fractional Golden Star shares will not be issued. Instead of receiving a fraction of a Golden Star share, you will receive a cash payment equal to such fraction multiplied by the current market price. For the purposes of determining the amount of any such cash payment, all IAMGold shares deposited by a registered holder will be aggregated.

      The depositary will act as the agent for you if you deposit your IAMGold shares into the offer for the purposes of receiving payment from us and transmitting such payment to you. Receipt of the share certificates and cash, if any, by the depositary shall be deemed to constitute receipt of payment by you.

      Settlement for the exchange will be made by the depositary forwarding (a) for your IAMGold shares (other than those representing fractional Golden Star shares), a certificate for the Golden Star shares to which you are entitled under the offer, provided that you are a resident of a province of Canada or another jurisdiction in which the Golden Star shares may be lawfully delivered without further action by us and (b) if applicable, a cheque in U.S. dollars in payment for the cash equivalent of any fractional Golden Star shares determined in accordance with the offer, that is payable to you. Subject to the foregoing and unless otherwise directed by the letter of transmittal, the certificates and any cheques will be issued in the name of the registered holder of the IAMGold shares so deposited. Unless you instruct the depositary to hold the certificate representing our shares and any cheque for pick-up by checking the appropriate box in the letter of transmittal, the certificate and any cheque will be forwarded by first class insured mail to such person at the address specified in the letter of transmittal. If no such address is specified, the certificate and any cheque will be sent to the address of the holder as shown on the securities register maintained by or on behalf of IAMGold. Certificates and cheques mailed in accordance with this paragraph will be deemed to be delivered at the time of mailing.

Time and Manner for Acceptance

      The offer is open for acceptance, unless withdrawn or extended at our sole discretion until the expiry time, being 9:00 p.m. (Toronto time), on July 16, 2004, unless the offer is withdrawn or extended.

      The offer may be accepted by you by depositing the following documents with the depositary at the offices specified in the letter of transmittal no later than the expiry time:

	(a) the certificate or certificates representing IAMGold shares in respect of which the offer is being accepted;
	(b) a properly completed and duly signed copy of the letter of transmittal (or a manually signed facsimile copy), with the signature or signatures guaranteed in accordance with the instructions set out in the letter of transmittal; and
	(c) any other relevant document required by the instructions set forth on the letter of transmittal.

      The offer will be deemed to be accepted only if the depositary actually has received these documents at or before the expiry time at one of the addresses for the depositary indicated on the letter of transmittal. If you cannot comply on a timely basis with these procedures for deposit of the requisite certificates for IAMGold shares, you may deposit certificates representing IAMGold shares pursuant to the procedures for guaranteed delivery described immediately below.

Procedure for Guaranteed Delivery

      If you wish to accept the offer and either (i) the certificates representing your IAMGold shares are not immediately available or (ii) you cannot deliver the certificates and letter of transmittal to the depositary by the expiry time, those IAMGold shares may nevertheless be deposited under the offer, provided that all of the following conditions are met:

	(a) such deposit is made only at the principal office of the depositary in Toronto by or through an eligible institution which means a Canadian Schedule 1 chartered bank, a major trust company in Canada, a member of a Securities Transfer Agent Medallion Program (STAMP), a member of the Stock Exchange Medallion Program (SEMP) or a member of the New York Stock Exchange, Inc. Medallion Signature Program (MSP). Members of these programs are usually members of a recognized stock exchange in Canada or the United States, members of the Investment Dealers Association of Canada, members of the National Association of Securities Dealers or banks and trust companies in the United States, referred to as an “eligible institution”;
	(b) a properly completed and duly executed notice of guaranteed delivery (or a manually signed facsimile) is received by the depositary at its principal office in Toronto at or before the expiry time; and

Extensions, Variations and Changes to the Offer

      The offer will be open for acceptance at the places of deposit specified in the letter of transmittal until, but not after, the expiry time.

Table of Contents

      We may, at any time and from time to time while the offer is open for acceptance, vary the terms of the offer or extend the expiry time by giving notice in writing to the depositary at its principal office in Toronto. Also, if at any time before the expiry time, or at any time after the expiry time, but before the expiry of all rights of withdrawal with respect to the offer, a change occurs in the information contained in this prospectus, as amended from time to time, that would reasonably be expected to affect your decision to accept or reject the offer (other than a change that is not within our control or of any of our affiliates), we will give written notice of such change to the depositary at its principal office in Toronto. Upon the giving of such notice to the depositary, the expiry time or withdrawal rights, as applicable, shall be deemed to be extended to the date specified in such notice or in the case of a variation the offer shall be deemed to be varied in the manner described in such notice, as the case may be. We will, as soon as practicable after giving any such notice to the depositary, publicly announce the extension, variation or change and cause the depositary to mail a copy of any such notice to IAMGold shareholders as required by applicable securities legislation at your address appearing in the share register of IAMGold. In addition, we will provide a copy of such notice to the TSX and AMEX. Any notice of extension, variation or change will be deemed to have been given and be effective on the day on which it is delivered or otherwise communicated to the depositary at its principal office in Toronto. During any extension of the offer, all IAMGold shares previously deposited and not taken up and paid for or withdrawn will remain subject to the offer and subject to applicable law may be accepted for purchase by us on or before the expiry time in accordance with the terms of the offer.

      An extension of the expiry time shall not in and of itself constitute a waiver by us of any of our rights.

      Under applicable Canadian provincial securities law, if there is a variation in the terms of the offer, the period during which IAMGold shares may be deposited under the offer shall not expire before 10 days after the notice of variation has been delivered. If, prior to the expiry time, we, in our sole discretion, increase the amount of consideration for your IAMGold shares, such increase shall be applicable to all holders whose IAMGold shares are taken up under the offer.

      Notwithstanding the foregoing, the offer may not be extended by us if all the terms and conditions of such offer have been complied with, except those waived by us, unless we first take up and pay for all IAMGold shares validly deposited and not withdrawn under the offer.

	Changes in Capitalization of IAMGold; Dividends and Distributions; Liens

      If, on or after the date of the offer, IAMGold should divide, combine, reclassify, consolidate, convert or otherwise change any of the IAMGold common shares or its capitalization, or should disclose that it has taken or intends to take any such action, then we may, in our sole discretion and without prejudice to our rights, make such adjustments as we deem appropriate to reflect such division, combination, reclassification, consolidation, conversion or other change in the purchase price, the number of our shares to be issued or other terms of the offer (including, without limitation, the type of securities offered to be purchased and the consideration payable therefor).

      IAMGold shares acquired from you pursuant to the offer shall be transferred by you and acquired by us free and clear of all liens, restrictions, charges, encumbrances, security interests, claims and equities or rights of others of any nature or kind whatsoever and together with all rights and benefits arising therefrom, including (subject to the payment of dividends as described below) the right to all other securities which may be declared, paid, issued, accrued, distributed, made or transferred on or after the date of the offer on in respect of the IAMGold shares.

      If, on or after the date of the offer, IAMGold declares or pays any dividend or declares, makes or pays any other distribution or payment on or declares, allots, reserves or issues any securities, rights or other interests with respect to the IAMGold shares, that is payable or distributable to the holders of such IAMGold shares on a record date that precedes the date of transfer of such IAMGold shares into our name or our nominees or transferees on the share register maintained by or on behalf of IAMGold then without prejudice to our rights: (a) in the case of cash dividends, distributions or payments, the amount of

	(b) if your IAMGold shares have not been paid for by us within three business days after having been taken up.

      A notice of withdrawal of deposited IAMGold shares must:

	(a) be made by a method that provides the depositary with a written or printed copy of such notice (which includes a telegraphic or electronic facsimile communication);

      In addition, any signature in the withdrawal notice must be guaranteed in the same manner as in the letter of transmittal or notice of guaranteed delivery, except where the IAMGold shares were deposited for the account of an eligible institution.

      Withdrawals may not be rescinded and any IAMGold shares withdrawn will thereafter be deemed not validly deposited for purposes of the offer. However, withdrawn IAMGold shares may be redeposited at any time before the expiry time by again following one of the appropriate procedures to deposit those shares.

Table of Contents

      In addition to the foregoing rights of withdrawal, in certain provinces of Canada you are entitled to statutory rights of rescission or damages or both in certain circumstances.

      All questions as to the validity (including timely receipt) and form of notices of withdrawal shall be determined by us in our sole discretion and such determinations shall be final and binding. Neither we, the depositary, or any other person will be under any duty to give notice of any defect or irregularity in any notice of withdrawal or shall incur any liability for failure to give such notice.

Return of Withdrawn IAMGold Shares

      If any deposited IAMGold shares are not taken up by us pursuant to the terms and conditions of the offer for any reason, or if certificates are submitted for more IAMGold shares than are deposited, certificates for IAMGold shares that are not purchased will be returned, at our expense, to you by first class registered or insured mail to your address specified in the letter of transmittal or, if no such address is specified, to your address as shown on the share register maintained by or on behalf of IAMGold. Certificates and other relevant documents will be returned as promptly as practicable following the expiry time or withdrawal or early termination of the offer.

Mail Service Interruption

      Notwithstanding the provisions of this prospectus, the letter of transmittal and the notice of guaranteed delivery, cheques, share certificates and any other relevant documents will not be mailed if we determine that delivery thereof by mail may be delayed. You may take delivery of these at the office of the depositary at which the IAMGold shares were delivered by you, upon application to the depositary, until such time as we have determined that delivery by mail will no longer be delayed. Notwithstanding the Notice and Delivery section below, the deposit of cheques, share certificates and any other relevant documents with the depositary in such circumstance shall constitute delivery to the persons entitled thereto and the IAMGold shares shall be deemed to have been paid for immediately upon such deposit. Notice of any determination regarding mail service delay or interruption made by us shall be given in accordance with the Notice and Delivery section below.

Notice and Delivery

      Without limiting any other lawful means of giving notice, any notice that we or the depositary may give or cause to be given under the offer will be deemed to have been properly given to you if it is mailed by prepaid, first class mail to the registered holders of such securities at their respective addresses appearing in the appropriate registers maintained by IAMGold and will be deemed, unless otherwise specified by applicable law, to have been received on the first business day following the date of mailing. These provisions apply notwithstanding any accidental omission to give notice and notwithstanding any interruption of mail service in Canada or the United States following mailing. In the event of any interruption of mail service in Canada or the United States, we intend to make reasonable efforts to disseminate the notice by other means such as publication. In the event that post offices are not open for the deposit of mail, or there is reason to believe that there is or could be a disruption in all or any part of the postal service, any notice which we or the depositary may give or cause to be given under the offer will be deemed to have been properly given and to have been received by you if it is given to the TSX and AMEX for dissemination through their facilities or if it is published in a newspaper or newspapers of general circulation in Toronto or if it is given to CCN Matthews News Service.

      Unless post offices are not open for the deposit of mail, this prospectus, the letter of transmittal and the notice of guaranteed delivery will be mailed to you. In addition, we will use reasonable efforts to furnish such documents to brokers, banks and similar persons whose names, or the names of whose nominees, appear on the security holder list, or, if applicable, who are listed as participants in a clearing agency’s security position listing, for subsequent transmission to beneficial owners of IAMGold shares when such list or listing is received.

Table of Contents

      Wherever the offer calls for documents to be delivered to the depositary, such documents will not be considered delivered unless and until they have been received at one of the offices specified in the letter of transmittal.

General

      The method of delivery of certificates representing IAMGold shares and all other documents is at your option and risk and delivery will be effective only when documents are actually received by the depositary. We recommend that certificates and accompanying letters of transmittal be delivered by hand to the depositary and that a receipt be obtained for their deposit. If the documents are mailed, we recommend that registered mail with return receipt or acknowledgement of receipt be used and that proper insurance be obtained.

      If your IAMGold shares are registered in the name of a broker, investment dealer, bank, trust company or other nominee, you should contact that nominee for assistance in depositing those IAMGold shares under the offer.

      No fee or commission will be payable by you if you deliver IAMGold shares directly to the depositary.

      We reserve the right to permit you to accept the offer in a manner other than as set out above.

      All questions as to the validity, form, eligibility (including timely receipt) and acceptance of any IAMGold shares deposited under the offer, including the propriety and effect of the execution of the letter of transmittal will be determined by us in our sole discretion, and you agree that such determination shall be final and binding. We reserve the absolute right to reject any and all deposits which we determine not to be in proper form, or which, in the opinion of counsel, it may be unlawful to accept under the laws of any jurisdiction. Our interpretation of the terms and conditions of the offer, the letter of transmittal and notice of guaranteed delivery will be final and binding. There shall be no obligation on us, the depositary, or any other person to give notice of any defect or irregularity in acceptance and no liability shall be incurred by any of them to any person for failure to give such notice.

      The deposit of your IAMGold shares pursuant to the procedures described in the offer will constitute a binding agreement between you and us and such agreement shall be subject to the conditions of the offer and include representations and warranties of you that: (i) you have full power and authority to deposit, sell, assign and transfer the IAMGold shares being deposited; (ii) you own the IAMGold shares being deposited; (iii) the deposit of the IAMGold shares complies with applicable securities laws; and (iv) when the IAMGold shares are taken up and paid for by us, in accordance with the offer, we will acquire good title thereto free and clear of all liens, restrictions, charges, encumbrances, claims and equities.

Other Terms of the Offer

      We reserve the right to transfer or assign to one or more of our affiliates the right to purchase all or any portion of the IAMGold shares deposited pursuant to the offer.

      The offer and all contracts resulting from the acceptance thereof shall be governed by and construed in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein.

      This prospectus does not constitute an offer or a solicitation to any person in any jurisdiction in which such offer or solicitation is unlawful. The offer is not being made or directed to, nor is this prospectus being mailed to, nor will deposits be accepted from or on behalf of, shareholders residing in any jurisdiction in which the making or acceptance of the offer would not be in compliance with the laws of such jurisdiction.

Effect of the Offer on the Market for and Listing of IAMGold Shares

      Our purchase of IAMGold shares pursuant to the offer will reduce the number of IAMGold shares that might otherwise trade publicly and will reduce the number of holders of IAMGold shares and, depending on the number of IAMGold shares acquired by us, could adversely affect the liquidity and market value of the remaining IAMGold shares held by you.

      The rules and regulations of the TSX and the AMEX establish certain criteria which, if not met, could, upon successful completion of the offer, lead to the delisting of the IAMGold shares from the TSX and the AMEX. Among such criteria are the number of IAMGold shareholders, the number of IAMGold shares publicly held and the aggregate market value of the IAMGold shares publicly held. Depending on the number of IAMGold shares purchased under the offer, it is possible that the IAMGold shares would fail to meet the criteria for continued listing on the TSX and the AMEX. If this were to happen, the IAMGold shares could be delisted and this could, in turn, adversely affect the market or result in a lack of an established market for such IAMGold shares. If permitted by applicable law, subsequent to completion of the offer or a compulsory acquisition or any subsequent acquisition transaction, if necessary, we intend to apply to delist the IAMGold shares from the TSX and the AMEX. If the IAMGold shares are delisted from the TSX and the AMEX, the extent of the public market for the IAMGold shares and the availability of price or other quotations would depend upon the number of shareholders, the number of IAMGold shares publicly held and the aggregate market value of the IAMGold shares remaining at such time, the interest in maintaining a market in IAMGold shares on the part of securities firms, whether we remain subject to public reporting requirements in Canada and the United States and other factors.

      After the purchase of the IAMGold shares under the offer, IAMGold may cease to be subject to the public reporting and proxy solicitation requirements of the CBCA and the securities laws of Canada and the United States or may request to cease to be a reporting issuer under the securities laws of such jurisdictions.

Regulatory Matters

      Our obligation to take up and pay for IAMGold shares tendered under the offer is conditional upon all appropriate regulatory approvals having been obtained on terms satisfactory to us, acting reasonably. Based upon an examination of the information publicly available relating to IAMGold’s business, we believe that the offer will be exempt from review by the Antitrust Division of the U.S. Department of Justice and the U.S. Federal Trade Commission under the Hart-Scott-Rodino Antitrust Improvements Act.

Securities Regulatory Matters

      The distribution of our shares under the offer is being made pursuant to statutory exemptions from the prospectus qualification and dealer registration requirements under applicable Canadian securities laws and, in certain provinces where such statutory exemptions are not available, will apply for exemptive relief from such requirements. While the resale of our shares issued under the offer is subject to restrictions under the securities laws of certain Canadian provinces and territories, shareholders in such provinces and territories generally will be able to rely on statutory exemptions from such restrictions and, where such statutory exemptions are not available, we will apply for exemptive relief from the applicable securities regulatory authorities to the effect that our shares to be issued under the offer may be resold without a prospectus.

      A Registration Statement on Form S-4 has been filed with the SEC registering the issuance of our shares as required by the U.S. Securities Act of 1933. Our shares may not be issued until the Registration

GOLDEN STAR

Corporate Overview

      We are a Canadian international gold mining and exploration company, focused primarily on mining, mine development and exploration in Ghana, West Africa. We produced 174,315 ounces of gold in 2003 at a cash operating cost of $166 per ounce, and 47,202 ounces in the first quarter of 2004 at a cash operating cost of $181 per ounce. We expect to produce from 185,000 to 210,000 ounces in 2004 at a cash operating cost of $200 to $225 per ounce.

      For the fiscal year ended December 31, 2003, we had revenues of approximately $64 million. We had net assets as at that date of approximately $198 million, with working capital of approximately $97 million. As at June 4, 2004, Golden Star’s market capitalization was approximately $668 million.

      We own 90% interests in two properties in Ghana, the Bogoso/Prestea open pit mine and related properties and the Wassa project. We operate the Bogoso/Prestea mine, with ore mined at the Prestea property being processed at the Bogoso processing plant. To date, Bogoso/Prestea has produced all of our gold since we became a gold producer upon our purchase of the Bogoso mine in late 1999. We commenced development of the Wassa mine in mid-2003. We expect to begin commercial production in the third quarter of 2004 by milling material from the existing heap leach pads, possibly supplemented by higher grade ore from the open pit mine, with full production from the open pit mine anticipated in early 2005. We also own a 61% managing interest in the currently inactive Prestea underground mine in Ghana. As part of our $21 million 2004 exploration program, we plan to spend $6.6 million in exploration underground as part of our effort to determine whether the underground mine can be reactivated on a profitable basis.

      Golden Star also holds interests in gold exploration properties in Ghana, Sierra Leone, Mali, Suriname and French Guiana.

      We are a reporting issuer or the equivalent in all provinces and territories of Canada and the United States and file continuous disclosure documents with the Canadian securities regulatory authorities and the United States Securities and Exchange Commission. Such documents are available at www.sedar.com and at www.sec.gov.

      Our principal place of business is located at 10901 W. Toller Drive, Littleton, Colorado, 80127-6312, U.S.A., telephone number (303) 830-9000.

Authorized and Outstanding Share Capital

      Our authorized share capital consists of an unlimited number of common shares and an unlimited number of first preferred shares issuable in series. As of June 8, 2004, there were 138,646,013 common shares issued and outstanding and no first preferred shares issued and outstanding.

Acceptance of the Offer

      We have no knowledge as to whether any IAMGold shareholder will accept the offer.

BACKGROUND TO THE OFFER

      We first discussed a possible business combination with IAMGold in September 2003. Joseph Conway, President and Chief Executive Officer of IAMGold, and Peter Bradford, President and Chief Executive Officer of Golden Star, met in Denver, Colorado, during a gold conference held in Denver from September 22 through September 24, 2003. In addition, there were meetings among Allan Marter, Senior Vice President and Chief Financial Officer of Golden Star; Bruce Higson-Smith, Vice President, Corporate Development of Golden Star; and Grant Edey, Chief Financial Officer of IAMGold. At these meetings, the participants engaged in preliminary discussions regarding the possibility of a business combination of Golden Star and IAMGold, and agreed to exchange certain operating and financial information in order to evaluate whether further discussions should take place.

      We entered into a confidentiality agreement with IAMGold dated September 25, 2003. In early October, Golden Star and IAMGold exchanged information about their respective properties, reserves, operations, plans and budgets, and financial results. During October and November, representatives of Golden Star and IAMGold analyzed the information received and engaged in occasional due diligence discussions. Mr. Bradford met with Mr. Conway in IAMGold’s offices in Toronto during the week of November 24, 2003. They discussed in general terms various aspects of a possible business combination between Golden Star and IAMGold, including a range of possible commercial terms and issues related to the blending of the boards of directors and executive officers of the two companies. Mr. Bradford and Mr. Conway both expressed their views that it appeared to be possible that Golden Star and IAMGold could negotiate a transaction acceptable to both parties. During meetings the week commencing on

      During this period, we also were considering other potential acquisitions and equity financing opportunities. On December 4, 2003, Mr. Bradford informed Mr. Conway that we were terminating discussions regarding a possible combination with IAMGold. Mr. Bradford subsequently confirmed the termination of discussions in a letter to Mr. Conway.

      From December 5, 2003 through March 30, 2004, we completed an equity financing and continued to consider other acquisition alternatives. Mr. Bradford and Mr. Conway spoke twice during this period in person and by telephone, and each indicated generally his interest in Golden Star and IAMGold recommencing discussions regarding a possible business combination once their annual reporting requirements had been completed. There were no other discussions regarding a business combination between representatives of Golden Star and IAMGold during this period.

      On March 30, 2004, IAMGold announced that it had entered into a pre-merger agreement with Wheaton River, pursuant to which, subject to certain conditions, Wheaton River shareholders would receive 0.55 IAMGold common shares for each common share of Wheaton River. IAMGold and Wheaton River subsequently entered into an arrangement agreement dated April 23, 2004, and amended and restated on April 29, 2004. IAMGold and Wheaton River each announced special meetings of their respective shareholders to be held on June 8, 2004 to consider the proposed transaction.

      Commencing on April 1, and continuing until and after May 27, when Golden Star announced its proposal of a business combination with IAMGold, Golden Star management has received telephone calls and other communications from a number of institutional shareholders of IAMGold, indicating their opposition to the proposed combination of IAMGold and Wheaton River, and suggesting that Golden Star commence an offer for IAMGold shares.

      On April 6, 2004, our Board of Directors met to discuss the relative merits of two potential transactions, including a possible offer for IAMGold. The Board concluded that it was interested in further investigation of a possible offer for IAMGold. The Board appointed a Special Committee composed of Messrs. David Fagin, Lars-Eric Johansson and Ian MacGregor, each an independent director. The Special Committee was authorized to instruct and direct Mr. Bradford in possible discussions and negotiations with IAMGold, to retain legal and financial advisors to assist and advise the Special Committee and Mr. Bradford, and to make recommendations to the Board of Directors regarding any possible business combinations. The Board appointed BMO Nesbitt Burns Inc. to provide financial advisory services and Fasken Martineau DuMoulin LLP to provide legal services with respect to a possible transaction with IAMGold, and instructed the Special Committee and Golden Star’s management to evaluate a possible transaction with or bid for IAMGold.

      During the months of April and May 2004, Golden Star’s management, with the assistance of its financial and legal advisors, obtained and analyzed certain publicly available information regarding IAMGold and constructed valuation models of IAMGold and its assets to determine the relative values of IAMGold and Golden Star. Management also worked with its financial and legal advisors to consider various structuring and transaction alternatives for the combination. Management also monitored the reaction of the markets, analysts and IAMGold shareholders to the IAMGold/Wheaton River transaction, as well as movements in the prices of Golden Star’s own shares. Members of the Special Committee engaged in frequent discussions with management and its financial and legal advisors regarding various financial, legal and business issues including pricing, valuations, transaction alternatives and strategic benefits. The Special Committee delivered periodic written updates to the Board regarding these matters during April.

Table of Contents

      The Board met with management to review management’s progress in analysis, valuations and proposed structuring and transaction alternatives on April 22 and April 27, and at its regularly scheduled meetings on April 29 and May 19. The financial and legal advisors participated in the April 22 Board meeting, and the financial advisors participated in the April 27 meeting. At the May 19, 2004 Board Meeting, the Special Committee was dissolved.

      On May 20, 2004, BMO Nesbitt Burns advised Golden Star that it had, through its relationship with a third party, become aware that Coeur d’Alene Mines Corporation was considering a proposal to Wheaton River. Mr. Bradford and Dennis Wheeler, the Chairman and Chief Executive Officer of Coeur d’Alene, spoke later that day. Mr. Wheeler confirmed Coeur d’Alene’s interest in Wheaton River and that its board of directors was considering a proposal to Wheaton River. Mr. Bradford confirmed Golden Star’s interest in IAMGold subject to the finalization of its valuation analysis. Between May 20, 2004 and May 26, 2004, the companies’ financial advisors discussed certain matters related to a possible business combination transaction and issues related to the break-fee clause in the arrangement agreement between IAMGold and Wheaton River. In that discussion and in a subsequent discussion on May 26, Mr. Wheeler and Mr. Bradford discussed the impact of the break fee clause in the arrangement agreement and agreed to a net payment of $26 million that would be paid by Coeur d’Alene to Golden Star if both parties were ultimately successful in their independent bids for IAMGold and Wheaton River.

      On May 26, 2004, the Board of Directors met with management and its financial and legal advisors to discuss a possible proposal for a business combination with IAMGold. The Board discussed the terms and conditions on which a proposal might be made, and instructed management and its financial and legal advisors to prepare a letter to IAMGold’s Chief Executive Officer regarding a proposal.

      On May 27, 2004 the Board of Directors met again with management and its financial and legal advisors and reviewed, discussed and approved the proposal to IAMGold and the related terms and conditions. Also on May 27, 2004 Golden Star entered into an agreement with Coeur d’Alene regarding the payment of break-fees under the arrangement as previously described. For more information regarding this agreement, see “Pre-Offer Agreement with Coeur d’Alene”.

      After the close of markets on May 27, 2004, Mr. Bradford met Mr. Conway and Larry Phillips, Vice President, Corporate Affairs and Corporate Secretary of IAMGold, together with financial and legal advisors, at the offices of IAMGold. Mr. Bradford advised Mr. Conway that Golden Star was proposing a business combination with IAMGold under which IAMGold shareholders would be offered 1.15 Golden Star shares for each IAMGold share, a premium of 13% over the IAMGold shares price based on the last sales prices on the TSX on May 27, 2004.

      Mr. Bradford further advised Mr. Conway that a formal offer by Golden Star would be conditional, among other things, on Golden Star having had an opportunity to perform confirmatory due diligence on IAMGold (which could be completed quickly once Golden Star received full access to necessary materials) and receiving appropriate support from IAMGold’s directors and shareholders. Mr. Bradford requested a list of IAMGold shareholders and the opportunity to meet with the Board of Directors of IAMGold at its earliest convenience to discuss the proposed combination and its benefits for IAMGold shareholders.

      Golden Star announced its proposal for a business combination with IAMGold by press release on May 27, 2004. Coeur d’Alene issued a press release on May 27, 2004 announcing its proposal to make an offer for the shares of Wheaton River. On May 28, 2004, Golden Star held a conference call for investors and other members of the public to discuss its proposal. Management and its financial advisors began conducting discussions and meetings with investors to assess shareholder support for the Golden Star proposal, and have continued to do so.

      Following telephone conversations between Mr. Bradford and each of Mr. Conway and Mr. Gordon Bogden (a director of IAMGold) on May 28 and 30, 2004 and delivery to the IAMGold directors of a letter from Mr. Bradford on May 31, 2004, each requesting an opportunity for Mr. Bradford to meet with the IAMGold directors to present Golden Star’s proposal, Mr. Bradford and a financial advisor made a

41

Table of Contents

      On June 1, 2004, Golden Star issued a press release reaffirming the merits of its proposal to IAMGold, noting positive market response to its proposal, and indicating that the arrangement agreement may have inappropriately restricted the IAMGold directors’ ability to consider alternative proposals. Also on June 1, Golden Star received a list of IAMGold shareholders accompanied by a letter from IAMGold’s legal counsel. The letter requested details of Golden Star’s proposed use of the shareholder list and threatened legal action if Golden Star were to make an offer to IAMGold shareholders regarding its proposed business combination. In particular, IAMGold alleged that the making of an offer by Golden Star would breach the “standstill” terms of the September 25, 2003 confidentiality agreement. IAMGold advised that it would seek appropriate remedies for any non-compliance with such provisions.

      After further correspondence between legal counsel to Golden Star and IAMGold failed to resolve this issue, Golden Star applied to the Ontario Superior Court of Justice for a declaration confirming Golden Star’s interpretation that Golden Star’s making an offer to IAMGold shareholders would not breach the confidentiality agreement. In addition, Golden Star sought an order enjoining the meeting of IAMGold shareholders scheduled for June 8, 2004 to provide for a court determination and for shareholders to assess a formal offer from Golden Star. Golden Star announced its application to the Court in a press release on June 2, 2004 and announced on June 4, 2004 that the Court would hear its application on June 7, 2004.

      Golden Star’s application was heard on Monday, June 7, 2004 by Madam Justice Hoy. An application commenced by certain shareholders of IAMGold who sought similar relief was also heard by Madam Justice Hoy. Wheaton River brought motions to the Court to intervene in both applications, which motions were granted by the Court. The Court reserved its decision until June 8, 2004. On that date Her Honour delivered oral reasons for the decision. Madam Justice Hoy declared that the terms of the confidentiality agreement do not prohibit Golden Star from making an offer. The Court also granted the relief requested by the shareholder applicants to postpone the IAMGold meeting until June 29, 2004.

      On June 8, 2004, the shareholders of Wheaton River approved the business combination contemplated by the arrangement agreement with IAMGold.

REASONS FOR THE PROPOSED COMBINATION

      We believe that the combination of Golden Star and IAMGold is a unique opportunity to create an intermediate gold producer with a portfolio of profitable gold operations and advanced exploration and development opportunities in West Africa. We believe that West Africa is host to one of the world’s most geologically prospective areas for future gold discoveries and development of large, low cost mining operations. We believe that the combination of Golden Star and IAMGold will produce the following valuable benefits.

      A leading intermediate gold producer. The combined company would have gold production of approximately 800,000 ounces per year commencing in 2005 and annual revenues of approximately $300 million at a gold price of $375 per ounce. Commencing in 2006, following completion of current development projects, the combined company would have estimated net free cash flow (after capital expenditures and exploration expense) in excess of $100 million per year. The combined company would have the largest reserve and resource base among intermediate producers, with approximately 7.3 million ounces of gold reserves and an additional 90 million tonnes of measured and indicated resources at an average grade of 1.6 grams per tonne. The new company would have significant potential to increase its resources and convert resources to reserves, particularly in our properties in Ghana.

Table of Contents

      Substantial cost savings. We estimate the combined company would achieve annual savings of approximately $8 million per year commencing in 2005, primarily through a combination of corporate overhead cost reductions and rationalization of our exploration programs.

      Financial strength. On a pro forma basis, the combined company would have a strong, liquid balance sheet, with approximately $185 million (assuming a break fee of $23 million is paid to Wheaton River) in cash, cash equivalents and bullion, with total long-term debt of approximately $12 million and sufficient cash flow to fund currently planned development activities. The combined company’s financial strength would provide excellent access to capital and an enhanced ability to expand the company’s portfolio of gold mines, development projects and exploration properties.

      Portfolio of West African gold mines. Golden Star and IAMGold are both gold producing companies focused on West Africa. Our Bogoso/ Prestea operation and Wassa development project, expected to commence production in the third quarter of 2004, are both in Ghana. IAMGold is also an established gold producer with mature production and cash flows from its minority interests in four large mines in West Africa, including the world-class Tarkwa and Sadiola mines in Ghana and Mali, respectively.

      Management strength. The Golden Star management team would bring to our combined company many years of hands-on operating and project development experience in Ghana and other parts of West Africa and Africa, with strong credibility in the capital markets.

      Stronger presence in West Africa. As a result of the proposed combination, we would emerge as the predominant intermediate gold mining company active in West Africa. With our extensive operating, project development and exploration experience and financial strength, we would have the opportunity to increase our portfolio by acquiring additional properties and by becoming the partner of choice for junior gold explorers in the region. We believe we would have greater flexibility than the senior gold companies active in West Africa in the pursuit of growth opportunities.

      Increased geological understanding. The knowledge base established by IAMGold’s past activity in West Africa, combined with Golden Star’s own ongoing and active exploration program, is expected to result in a widespread geological understanding in West Africa. We believe this will provide unique potential for organic growth that we can capitalize on with our in-house project development and operational skills.

      Increased competitiveness. With its financial and management strength, enhanced geological understanding and significant presence in West Africa, the combined company would have increased ability to compete for world-class gold projects in the region.

      Increased market profile. The combined company would have a market capitalization of approximately $1.4 billion based on the last trading prices of our respective shares on June 8, 2004. Due to the increased market capitalization, the shares of the combined company would be eligible investments for additional potential institutional investors in the U.S. and Canada. Most of Golden Star’s trading activity is on the AMEX, and most of IAMGold’s trading activity is on the TSX. The combined company should achieve an excellent balance of capital markets participation across the U.S.-Canadian border, with anticipated daily trading volumes of from $25 to $30 million per day.

PLANS FOR GOLDEN STAR AND IAMGOLD FOLLOWING

      Our focus has been to acquire holdings in Ghana in areas from which significant amounts of gold have historically been produced and where we believe there are excellent opportunities for the discovery of additional gold. More recently, we have expanded our focus to include exploration for new gold discoveries in new prospective areas, in southeast Mali and in Sierra Leone.

      Following the acquisition of IAMGold, Golden Star would emerge as a dominant intermediate size gold producer with strong, diversified cash flow from six operations in Ghana and Mali and a royalty portfolio. We would have continuing production growth in 2004 and 2005 as Wassa begins operations, production at Bogoso/Prestea increases and the Tarkwa expansion is completed. We expect to fund the current development projects of the combined company primarily from free net cash flow, preserving and growing the combined treasury of approximately $185 million (assuming we pay a $23 million break fee to Wheaton River) to enable us to respond quickly to attractive growth opportunities.

      Golden Star, following the acquisition, would continue to have its operations and immediate development and exploration activities concentrated in West Africa, a part of the world where we believe there is excellent potential for new gold discoveries and the development of new gold mines. The fact that three of the top four gold producers have significant operations in the region supports our view.

      As the dominant intermediate gold producer in this region, with substantial cash flow from existing operations, we should be a leader in the exploration for new gold discoveries and in the acquisition of existing gold projects. We already have operating credibility in this region. We intend to be the partner of choice for junior companies operating in West Africa, several of which have advanced exploration or development stage projects but do not possess project development or operating expertise. We would have sufficient cash and cash flow to be a partner of choice for senior companies and to take advantage of the acquisition opportunities presented by senior gold company dispositions.

      In West Africa, local experience and knowledge is crucial. We have extensive experience in Ghana, and have begun to develop our knowledge of Sierra Leone and Mali. IAMGold explored actively in West Africa during the early to mid 1990s, and we expect our exploration efforts to benefit substantially from the combination of the two companies.

Delisting

      If permitted by applicable law, subsequent to the completion of the offer and, if necessary, any compulsory acquisition or any subsequent acquisition transaction (as defined below), we intend to delist the IAMGold shares from the TSX and AMEX and, where applicable, to cause IAMGold to cease to be a reporting issuer.

      As referenced in “Background of the Offer”, a break fee is payable by IAMGold to Wheaton River if the arrangement agreement is terminated in the following events: (i) Wheaton River terminates the arrangement agreement if an acquisition proposal is determined by IAMGold’s directors to be a “Superior Proposal”, as defined in the arrangement agreement, and the directors of IAMGold withdraw or modify their recommendation of the transactions contemplated in the arrangement agreement or approve, recommend or enter into any agreement with respect to the Superior Proposal; (ii) IAMGold terminates the arrangement agreement on the basis that another acquisition proposal is a Superior Proposal (after having given Wheaton River the opportunity to match the offer); (iii) if an acquisition proposal is not withdrawn prior to IAMGold’s shareholders meeting and the shareholders of IAMGold do not approve the transactions contemplated in the arrangement agreement (and the arrangement agreement is terminated on that basis) and IAMGold completes the business combination with the person who proposed the acquisition proposal within 9 months from the date of termination of the arrangement agreement; or (iv) IAMGold shareholders do not approve the transactions and certain other matters on or before

      In accordance with the terms of their agreement, Golden Star and Coeur d’Alene agreed to net the potential break fees payable under the arrangement agreement such that if both Golden Star and Coeur d’Alene complete their proposed combinations with IAMGold and Wheaton River, respectively, Coeur d’Alene or Wheaton shall pay to IAMGold a fee of $26 million in lieu of either party paying a break fee under the arrangement agreement.

      On June 8, 2004, the shareholders of Wheaton River approved the business combination contemplated by the arrangement agreement with IAMGold. As a result of this approval, it is less likely that we, through our ownership of IAMGold, will receive a break fee and IAMGold may be obligated to pay the break fee referred to above. We estimate the break fee payable to IAMGold to be approximately $23 million.

ACQUISITION OF SHARES NOT DEPOSITED

	Compulsory Acquisition

      If, within 120 days after the date of the offer, the offer has been accepted by the holders of not less than 90% of the issued and outstanding IAMGold shares, other than IAMGold shares held at the date of the offer by or on behalf of us or our affiliates and associates (as such terms are defined in the Canadian Business Corporations Act, or CBCA), and we acquire the deposited IAMGold shares under the offer, we currently intend to perform a compulsory acquisition where we would acquire the IAMGold shares not deposited under the offer on the same terms as the IAMGold shares acquired under the offer pursuant to the provisions of section 206 of the CBCA, referred to as a compulsory acquisition.

      To complete the compulsory acquisition, we must give notice to each IAMGold shareholder who did not accept the offer (and each person who subsequently acquires any such IAMGold shares) and to the director under the CBCA of such proposed acquisition on or before the earlier of 60 days from the date of the termination of the offer and 180 days from the date of the offer. Within 20 days of the giving of the notice by us, we must pay or transfer to IAMGold the consideration we would have had to pay or transfer to the dissenting offerees if they had elected to accept the offer, to be held in trust for the dissenting offerees. In accordance with section 206 of the CBCA, within 20 days after receipt of the notice from us, each dissenting offeree must send the certificates representing the IAMGold shares held by such dissenting offeree to IAMGold, and must elect either to transfer such IAMGold shares to us on the terms of the offer or to demand payment of the fair value of such IAMGold shares held by such holder. A dissenting offeree who does not notify us within 20 days after the person receives our notice is deemed to have elected to transfer such IAMGold shares to us on the same terms that we acquired IAMGold shares from shareholders who accepted the offer. If a dissenting offeree has elected to demand payment of the fair value of such IAMGold shares, we may apply to a court having jurisdiction to hear an application to fix the fair value of such IAMGold shares of such dissenting offeree. If we fail to apply to the court within 20 days after we made the payment or transferred the consideration to IAMGold referred to above, the dissenting offeree may then apply to the court within a further period of 20 days to have the court fix the fair value. If there is no such application made by the dissenting offeree within such period, the dissenting offeree will be deemed to have elected to transfer such IAMGold shares to us on the same terms that we acquired IAMGold shares from shareholders who accepted the offer. Any judicial determination of the fair value of the IAMGold shares could be more or less than the amount paid under the offer.

      The foregoing is a summary only of the right of a compulsory acquisition that may become available to us and is qualified in its entirety by the provisions of section 206 of the CBCA. Section 206 of the CBCA is complex and may require strict adherence to notice and timing provisions, failing which such rights may be lost or altered. Shareholders who wish to be better informed about the provisions of section 206 of the CBCA should consult their legal advisors. See “Certain Canadian Federal Income Tax

	Compelled Acquisition

      If you do not receive the notice from us regarding a compulsory acquisition, you may, within 90 days after the date of the termination of the offer, or if you did not receive the offer, within 90 days of the later of the date of termination of the offer and the date on which you learned of the offer, require us to acquire your IAMGold shares on the terms of the offer.

      The foregoing is a summary only of the right of compelled acquisition that may be available to you and is qualified in its entirety by the provisions of section 206.1 of the CBCA. Section 206.1 of the CBCA is complex and may require strict adherence to notice and timing provisions, failing which such rights may be lost or altered. If you wish to be better informed about the provisions of section 206.1 of the CBCA, you should consult your legal advisors.

	Subsequent Acquisition Transaction

      If we take up and pay for IAMGold shares validly deposited under the offer and the right of compulsory acquisition described above is not available or we elect not to pursue such right, we currently intend to cause a special meeting of IAMGold shareholders to be called to consider an amalgamation, statutory arrangement, capital reorganization or other transaction involving IAMGold and Golden Star or an affiliate for the purpose of enabling us or our affiliate to acquire all IAMGold shares not acquired pursuant to the offer, referred to as a subsequent acquisition transaction. The timing and details of any such subsequent acquisition transaction will depend on a number of factors, including the number of IAMGold shares acquired pursuant to the offer. If at least 66 2/3% of the issued and outstanding IAMGold shares are taken up under the offer, we should own sufficient IAMGold shares to effect a subsequent acquisition transaction. While we currently intend that the consideration offered under any subsequent acquisition transaction would be the same consideration as the consideration offered under the offer, the consideration offered to holders of IAMGold shares in a subsequent acquisition transaction could ultimately have a higher or lower value than the value of the consideration pursuant to the offer.

      Each type of subsequent acquisition transaction described above would be a “going private transaction” within the meaning of certain applicable Canadian securities legislation and regulations, the Ontario Securities Commission, referred to as the “OSC,” Rule 61-501 and the Autorité de marchés financiers (Quebec), referred to as the “AMF,” Policy Q-27, if such subsequent acquisition transaction would result in your interest in IAMGold being terminated without your consent. In certain circumstances, the provisions of Rule 61-501 and Policy Q-27 may also deem certain types of subsequent acquisition transactions to be “related party transactions”. However, if the subsequent acquisition transaction is a “going private transaction” carried out in accordance with Rule 61-501 or an exemption therefrom and Policy Q-27 or an exemption therefrom, the “related party transaction” provisions of Rule 61-501 and Policy Q-27 would not apply to such transaction. We intend to carry out any such going private transaction in accordance with Rule 61-501 and Policy Q-27 or exemptions therefrom such that the related party transaction provisions of Rule 61-501 and Policy Q-27 will not apply to the going private transaction.

      Canadian securities legislation and regulations, Rule 61-501 and Policy Q-27 provide that, unless exempted, a corporation proposing to carry out a going private transaction is required to prepare a valuation of the IAMGold shares (and subject to certain exceptions, any non-cash consideration being offered therefor) and provide to the holders of the IAMGold shares a summary of such valuation or the entire valuation. In connection therewith, we intend to rely on any exemption then available or to seek waivers pursuant to Rule 61-501 and Policy Q-27 from the OSC and AMF, respectively, exempting us, IAMGold and any affiliates, as appropriate, from the requirement to prepare a valuation in connection with any subsequent acquisition transaction.

      Depending on the nature of the subsequent acquisition transaction, the provisions of the CBCA may require the approval of at least 66 2/3% of the votes cast by holders of the outstanding IAMGold shares at a

      In addition, under Rule 61-501 and Policy Q-27, if, following the offer, we and our affiliates are the registered holders of 90% or more of the IAMGold shares at the time the subsequent acquisition transaction is initiated, the requirement for minority approval would not apply to the transaction if a statutory right to dissent and seek fair value or a substantially equivalent enforceable right is made available to the minority shareholders. If we decide not to effect a compulsory acquisition or propose a subsequent acquisition transaction involving IAMGold, or we propose a subsequent acquisition transaction but cannot promptly obtain any required approval or exemption, we will evaluate our other alternatives. Such alternatives could include, to the extent permitted by applicable law, purchasing additional IAMGold shares in the open market, in privately negotiated transactions, in another take-over bid or exchange offer or otherwise, or from IAMGold, or taking no further action to acquire additional IAMGold shares. Any additional purchases of IAMGold shares could be for consideration greater than, equal to or less than that to be paid for IAMGold shares under the offer and could be for cash and/or securities or other consideration. Alternatively, we may sell or otherwise dispose of any or all IAMGold shares acquired pursuant to the offer or otherwise. Such transactions may be effected on terms and at prices then determined by us, which may vary from the terms and the price paid for IAMGold shares under the offer.

      Any subsequent acquisition transaction may also result in you having the right to dissent and demand payment of the fair value of your IAMGold shares. If the statutory procedures are complied with, this right could lead to a judicial determination of the fair value required to be paid to you for your IAMGold shares. The fair value of IAMGold shares so determined could be more or less than the amount paid per IAMGold shares pursuant to the subsequent acquisition transaction or the offer.

      The tax consequences to you of a subsequent acquisition transaction may differ significantly from the tax consequences to you of accepting the offer. See “Certain Canadian Federal Income Tax Considerations” and “Certain U.S. Income Tax Considerations”, respectively. You should consult your legal advisors for a determination of your legal rights with respect to a subsequent acquisition transaction if and when proposed.

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

General

      The following is a summary, as of the date hereof, of the principal Canadian federal income tax consequences generally applicable to shareholders who dispose of their IAMGold shares pursuant to the offer and who, for purposes of the Income Tax Act (Canada), or Tax Act, hold their IAMGold shares as

47

---

Table of Contents

      This summary is based upon the current provisions of the Tax Act, the regulations thereunder, all proposed amendments to the Tax Act or the regulations announced by the Minister of Finance prior to the date hereof and our understanding of the current published administrative and assessing practices of Canada Revenue Agency, referred to as the CRA. This summary does not otherwise take into account or anticipate changes in the law, whether by way of judicial, governmental or legislative decision or action, nor does it take into account provincial, territorial or foreign tax legislation or considerations.

      This summary is of a general nature only and is not exhaustive of all possible Canadian federal income tax considerations. This summary is not intended to be, nor should it be construed to be, legal or tax advice to any particular shareholder and, accordingly, shareholders should consult their own independent tax advisors for advice with respect to the income tax consequences to them of disposing of their IAMGold shares having regard to their own particular circumstances.

Shareholders Resident in Canada

      In addition to the comments set out under the heading “General,” this portion of the summary is applicable only to shareholders who are resident or deemed to be resident in Canada for purposes of the Tax Act, referred to as the resident shareholders.

      Certain resident shareholders whose IAMGold shares might not otherwise qualify as capital property may, in certain circumstances, make an irrevocable election in accordance with subsection 39(4) of the Tax Act to have their IAMGold shares and every “Canadian security” (as defined in the Tax Act) owned by such holders in the taxation year of the election and in all subsequent taxation years deemed to be a capital property.

Resident Shareholders Accepting the Offer

      A resident shareholder who exchanges IAMGold shares pursuant to the offer for our shares will, unless the resident shareholder chooses otherwise, be deemed to have disposed of such IAMGold shares for proceeds of disposition equal to the resident shareholder’s adjusted cost base thereof. Such resident shareholder would therefore neither recognize a capital gain nor a capital loss in respect of the exchange and would be deemed to acquire our shares at a cost which is equal to the adjusted cost base of our shares for the purposes of computing the adjusted cost base of all Golden Star shares owned by them for purposes of the Tax Act.

      Under the current administrative and assessing practice of the CRA, a resident shareholder who receives cash in an amount which does not exceed Cdn$200 in lieu of a fraction of a Golden Star share pursuant to the exchange of shares under the offer may ignore the computation of any gain or loss on the disposition of the fractional share and reduce the adjusted cost base of the Golden Star shares received on the exchange by the amount of such cash. In the alternative, a resident shareholder may include the capital gain or loss arising on the disposition of the fractional share in the computation of that resident shareholder’s income.

      Notwithstanding the foregoing, resident shareholders who receive Golden Star shares in exchange for their IAMGold shares may, if they so choose, recognize a capital gain or a capital loss in respect of such disposition by reporting the same in their income tax return for the taxation year during which the

Acquisition of Shares Not Deposited

	Compulsory Acquisition

      We may acquire IAMGold shares not deposited under the offer pursuant to a compulsory acquisition. The consequences under the Tax Act of any compulsory acquisition will depend upon the consideration offered by us in respect thereof. Generally speaking, to the extent the IAMGold shares are acquired by us for our shares, the consequences to resident shareholders will generally be as set out above under the heading “Resident Shareholders Accepting the Offer.”

      A resident shareholder who dissents in a compulsory acquisition and elects to receive the fair value for the holder’s IAMGold shares will be considered to have disposed of the IAMGold shares for proceeds of disposition equal to the amount received by the resident shareholder less the amount of interest awarded by the court and will realize a capital gain (or a capital loss) in the manner, and subject to the treatment, described above in the last paragraph under “Resident Shareholders Accepting the Offer.” Any interest awarded to the resident shareholder by the court will be included in the resident shareholder’s income for the purposes of the Tax Act.

	Subsequent Acquisition Transaction

      If we do not acquire all of the IAMGold shares pursuant to the offer or by means of a compulsory acquisition, we may propose other means of acquiring the remaining issued and outstanding IAMGold shares. It is our current intention that the consideration offered under any subsequent acquisition transaction would be identical to the consideration offered under the offer. The tax treatment of a subsequent acquisition transaction to a resident shareholder will depend upon the exact manner in which the subsequent acquisition transaction is carried out.

      We may propose to carry out a subsequent acquisition transaction by means of an amalgamation, statutory arrangement, capital reorganization, consolidation or other transaction, the tax consequences of which would depend upon the nature of the particular transaction undertaken and may be substantially the same as, or materially different from, those described above. Depending upon the exact manner in which the transaction is carried out, such tax consequences may include a capital gain or capital loss, a deemed dividend or both a deemed dividend and a capital gain or capital loss. Any such capital loss may, in certain circumstances, be reduced by the amount of certain dividends previously received or deemed to have been received on your IAMGold shares (or on shares of an amalgamated corporation for which the IAMGold shares are exchanged) to the extent and under the circumstances described in the Tax Act.

      A resident shareholder that is a corporation should consult its tax advisors for specific advice with respect to the potential application of subsection 55(2) of the Tax Act with respect to any dividends received, or deemed to be received, by such corporation in connection with a subsequent acquisition

49

---

Table of Contents

      A resident shareholder that is a “private corporation” or a “subject corporation” (as such terms are defined in the Tax Act) may be liable under Part IV of the Tax Act to pay a refundable tax of 33 1/3% on dividends received, or deemed to be received, in connection with a subsequent acquisition transaction to the extent that such dividends are deductible in computing such corporation’s taxable income.

      In the case of a resident shareholder who is an individual (including a trust), dividends received or deemed to be received in connection with a subsequent acquisition transaction will be included in computing the resident shareholder’s income, and will be subject to the gross-up and dividend tax credit rules normally applicable to taxable dividends paid by a taxable Canadian corporation.

      If the subsequent acquisition transaction is carried out by means of an amalgamation, under the current administrative practice of the CRA, resident shareholders who exercise their right of dissent in respect of such an amalgamation should be considered to have disposed of their IAMGold shares for proceeds of disposition equal to the amount paid by the amalgamated corporation to the dissenting resident shareholder for such shares, other than interest awarded by the court. Because of uncertainties under the relevant legislation as to whether such amounts paid to a dissenting resident shareholder would be treated entirely as proceeds of disposition, or in part as the payment of a deemed dividend, dissenting resident shareholders should consult with their tax advisors in this regard.

      Resident shareholders should consult their own tax advisors for advice with respect to the income tax consequences to them of having their IAMGold shares acquired pursuant to a subsequent acquisition transaction.

	Shareholders Not Resident in Canada

      In addition to the comments set out above under the heading “General,” this portion of the summary is applicable to shareholders who, for purposes of the Tax Act, have not been resident in Canada or deemed to be resident in Canada at any time while they held their IAMGold shares, do not carry on an insurance business in Canada and who do not use or hold and are not deemed to use or hold their IAMGold shares in carrying on a business in Canada. Such persons are referred to as non-resident shareholders below.

Non-Resident Shareholders Accepting the Offer

      A non-resident shareholder will not be subject to tax under the Tax Act in respect of any capital gain realized on a disposition of IAMGold shares pursuant to the offer unless such shares are or are deemed to be “taxable Canadian property” and the non-resident shareholder is not afforded any relief under an applicable tax treaty.

      Generally, IAMGold shares will not be taxable Canadian property at a particular time provided that such shares are listed on a prescribed stock exchange (which includes the TSX and the AMEX), unless:

	(a) at any time during the five year period immediately preceding the disposition of the IAMGold shares by such non-resident shareholder, the non-resident shareholder, persons not dealing at arm’s length with such non-resident shareholder, or any combination thereof owned (or had options to acquire) not less than 25% of the issued shares of any class or series of the capital stock of IAMGold; or
	(b) the non-resident shareholder’s IAMGold shares were acquired in certain types of tax deferred exchanges in consideration for property that was itself taxable Canadian property.

50

Table of Contents

      Even if the IAMGold shares are taxable Canadian property to a non-resident shareholder and the disposition would give rise to a capital gain, an exemption from tax may be available under the terms of an applicable income tax treaty between Canada and the country of residence of the non-resident shareholder.

Acquisition of Shares Not Deposited

      The consequences under the Tax Act to a non-resident shareholder of any compulsory acquisition or subsequent acquisition transaction would depend upon the nature of the transaction. In general, the non-resident shareholder would not be subject to taxation under the Tax Act in respect of any capital gain that is recognized unless the non-resident shareholder’s IAMGold shares are taxable Canadian property, as described above, and the non-resident shareholder is not afforded any relief under an applicable tax treaty.

	Compulsory Acquisition

      A non-resident shareholder who dissents in a compulsory acquisition and elects to receive the fair value for the holder’s IAMGold shares will be considered to have disposed of the IAMGold shares for proceeds of disposition equal to the amount received by the resident shareholder less the amount of interest awarded by the Court. In such circumstances, the non-resident shareholder would not be subject to taxation under the Tax Act in respect of any capital gain that is recognized unless the non-resident shareholder’s IAMGold shares are taxable Canadian property, as described above, and the non-resident shareholder is not afforded any relief under an applicable tax treaty.

      Interest awarded to a dissenting non-resident shareholder by a court will be subject to non-resident withholding tax at the rate of 25% unless the rate is reduced under the provisions of an applicable tax treaty.

	Subsequent Acquisition Transactions

      If we acquire less than 90% of the IAMGold shares under the offer or the right of compulsory acquisition is not available for any reason or if we elect not to proceed under such provisions, we may propose other means of acquiring the remaining issued and outstanding IAMGold shares. It is our current intention that the consideration offered under any subsequent acquisition transaction would be identical to the consideration offered under the offer. The tax treatment of a subsequent acquisition transaction to a non-resident shareholder will depend upon the exact manner in which the subsequent acquisition transaction is carried out. A non-resident shareholder may realize a capital gain or a capital loss and/or a deemed dividend. Dividends paid or deemed to be paid to a non-resident shareholder will be subject to Canadian withholding tax at a rate of 25%. This rate may be reduced under the provisions of an applicable income tax treaty.

      Non-resident shareholders should consult their own tax advisors for advice with respect to the potential income tax consequences to them of having their IAMGold shares acquired pursuant to a compulsory acquisition or subsequent acquisition transaction.

CERTAIN U.S. INCOME TAX CONSIDERATIONS

      The following is a summary of the material anticipated U.S. Federal income tax consequences of exchanging IAMGold shares for our common shares pursuant to the offer. This summary is based upon the U.S. Internal Revenue Code of 1986, as amended, referred to as the “Code,” treasury regulations promulgated under the Code, administrative rulings of the U.S. Internal Revenue Service, referred to as the “IRS”, and judicial decisions of the U.S. courts, in each case as in effect on the date hereof. Changes in the laws may alter the U.S. Federal income tax treatment of our common shares discussed in this summary, possibly with retroactive effect.

      This summary is general in nature and does not address the effects of any state or local taxes, or the tax consequences in jurisdictions other than the United States. In addition, this summary does not address

	•	a person that owns, has owned, or will own 5% or more (by voting power or value, and taking into account certain attribution rules) of our issued and outstanding shares or IAMGold shares;
	•	a broker, dealer or trader in securities or currencies, or any person who owns IAMGold shares or our shares other than as capital assets within the meaning of Section 1221 of the Code;
	•	a bank, mutual fund, life insurance company or other financial institution;
	•	a tax-exempt organization;
	•	a real estate investment trust or regulated investment company;
	•	a qualified retirement plan or individual retirement account;
	•	a person that holds or will hold their IAMGold shares or Golden Star shares as part of a straddle, hedge, constructive sale or other integrated transaction for tax purposes;

	•	an investor in a partnership, S corporation or other “pass-through” entity, as determined for U.S. Federal income tax purposes;
	•	a person whose functional currency for tax purposes is not the U.S. dollar;
	•	a person liable for alternative minimum tax.

      It is assumed for purposes of this summary that we are not, have not at any time been and will not be after this offering (a) a “controlled foreign corporation,” as defined in Section 957(a) of the Code, (b) a “foreign investment company,” as defined in Section 1246(b) of the Code or (c) a “foreign personal holding company,” as defined in Section 552 of the Code.

      HOLDERS OF IAMGOLD SHARES ARE URGED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE TAX CONSEQUENCES OF THE ACQUISITION PURSUANT TO THE OFFER, OWNERSHIP AND DISPOSITION OF OUR SHARES IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES, AS WELL AS THE TAX CONSEQUENCES UNDER STATE, LOCAL AND NON-UNITED STATES TAX LAW AND THE POSSIBLE EFFECTS OF CHANGES IN TAX LAW.

      For purposes of this discussion, a “U.S. Holder” means a beneficial owner of a common share of IAMGold, or Golden Star, as the case may be, who is, for U.S. Federal income tax purposes:

	•	an individual citizen or resident of the United States;
	•	a corporation created or organized in or under the laws of the United States or any political subdivision thereof;
	•	an estate the income of which is subject to U.S. Federal income taxation regardless of its source; or
	•	a trust (1) that validly elects to be treated as a U.S. person for U.S. Federal income tax purposes or (2) the administration over which a U.S. court can exercise primary supervision and all of the substantial decisions of which one or more U.S. persons have the authority to control.

      “Non-U.S. Holder” means any person who owns shares of IAMGold, or our shares, as the case may be, and who is not a U.S. Holder.

      If a “pass-through” entity holds IAMGold shares, the tax treatment of an owner of such “pass-through” entity generally will depend upon the status of such owner and upon the activities of the “pass-through” entity. An owner of “pass-through” entity holding IAMGold shares should consult such owner’s tax advisor regarding the specific tax consequences of exchanging IAMGold shares in the offer.

U.S. Holders of IAMGold Shares

	Consequences of Exchanging IAMGold Shares Pursuant to the Offer

      We will endeavor to cause the exchange of IAMGold shares pursuant to the offer to be treated as an exchange pursuant a “reorganization” within the meaning of Section 368(a)(1) of the Code. Any such reorganization likely would be treated as including the exchange of IAMGold shares made pursuant to any compulsory acquisition transaction. However, reorganization treatment may or may not be available, depending upon the precise outcome of any compulsory acquisition or subsequent acquisition transaction. Each U.S. Holder is urged to take into account the possibility that a transfer of IAMGold shares pursuant to the offer may not qualify as an exchange pursuant to a “reorganization” under Section 368(a)(1) of the Code.

      If the exchange of IAMGold shares pursuant to the offer qualifies as an exchange pursuant to a reorganization under Section 368(a)(1) of the Code, the exchange should have the following U.S. Federal income tax consequences:

	•	Golden Star and IAMGold will be treated as “parties to the reorganization” under Section 368(b) of the Code.
	•	No gain or loss will be recognized by a U.S. Holder of IAMGold shares on the exchange of those shares for our shares.
	•	The aggregate adjusted tax basis of our shares received in the exchange by a U.S. Holder will be the same as the aggregate adjusted tax basis of such U.S. Holder’s IAMGold shares exchanged therefore.
	•	The holding period of our shares received in the exchange by a U.S. Holder will include the holding period of such U.S. Holder’s IAMGold shares exchanged therefore.
	•	The receipt of cash in lieu of a fractional Golden Star share by a U.S. Holder will generally result in taxable gain or loss to the U.S. Holder equal to the difference between the amount of cash received by the U.S. Holder and the U.S. Holder’s adjusted tax basis in such fractional share. Such gain or loss will be capital gain or loss and will be long-term capital gain or loss if the U.S. Holder’s holding period exceeds one year upon the closing of the exchange. However, in certain circumstances in which a U.S. Holder maintains a sufficient interest in Golden Star (both direct and constructive), the amount of a cash payment received in lieu of a fractional share by the U.S. Holder may be treated as dividend income to the extent paid out of earnings and profits.

      U.S. Holders of IAMGold shares who have acquired different lots of IAMGold shares for different prices per share should consult with their U.S. tax advisors to determine whether they may identify specific lots of our shares as received in exchange for the different lots of IAMGold shares.

      If the exchange of IAMGold shares for our shares fails to qualify as an exchange pursuant to a reorganization under Section 368(a)(1) of the Code, a U.S. Holder will recognize taxable gain or loss equal to the difference between the fair market value of our shares received in the offer and the U.S. Holder’s adjusted basis in the IAMGold shares exchanged. Any such gain or loss generally will be capital gain or loss, and will be long-term capital gain or loss if the U.S. Holder’s holding period in the IAMGold shares exceeds one year upon the consummation of the exchange pursuant to the offer.

      For non-corporate U.S. Holders, long-term capital gain recognized in connection with an exchange made pursuant to the offer generally will be taxed at a maximum U.S. Federal income tax rate of 15%. The deductibility of capital losses is subject to limitations.

      The tax consequences described above are based upon the assumption that IAMGold is not, and has not been, a passive foreign investment company referred to as a “PFIC.” If IAMGold were a PFIC for the taxable year that includes any portion of a U.S. Holder’s holding period in IAMGold shares, the tax

Table of Contents

	•	if the exchange is in pursuance of a reorganization under Section 368(a)(1) of the Code, the U.S. Holder would recognize gain (but not loss) on the exchange of IAMGold shares in return for our shares pursuant to the offer, and would recognize gain or loss, or, in some circumstances, dividend income, on the receipt of cash in lieu of fractional shares, with all such gain or income treated as ordinary income; and
	•	if the exchange does not qualify as a reorganization under Section 368(a)(1) of the Code, the U.S. Holder would recognize gain or loss, with such gain treated as ordinary income.

In either case, any such gain or income would be subject to tax as an “excess distribution” at the highest marginal rates applicable to ordinary income, and would be subject to interest charges to reflect the value of the U.S. income tax deferral, unless the U.S. Holder has timely made an election to mark the IAMGold shares to market or to treat IAMGold as a “qualified electing fund.”

	Transfer of IAMGold Shares Not Exchanged Pursuant to the Offer

      We may acquire IAMGold shares not exchanged in the offer pursuant to a compulsory acquisition. The consequences to a U.S. Holder of any compulsory acquisition will depend upon the consideration issued by Golden Star in the compulsory acquisition. To the extent the IAMGold shares are acquired by us for our shares, the consequences to a U.S. Holder should generally be similar to the consequences to a U.S. Holder of exchanging IAMGold shares for our shares pursuant to the offer. Such consequences will depend upon whether the exchange qualifies as an exchange pursuant to a reorganization under Section 368(a)(1) of the Code. See “U.S. Holders of IAMGold Shares — Consequences of Exchanging IAMGold Shares Pursuant to the Offer,” above.

      A U.S. Holder that exercises dissent rights and receives cash for its IAMGold shares will recognize gain or loss based on the difference between the cash received and the holder’s adjusted tax basis in the IAMGold shares exchanged. Any such gain or loss would generally be treated in the same manner as gain or loss that is recognized in an exchange made pursuant to the offer, as described under “U.S. Holders — Consequences of Exchanging IAMGold shares Pursuant to the Offer,” above.

      If we do not acquire all of the IAMGold shares pursuant to the offer or by means of a compulsory acquisition, we may propose other means of acquiring the remaining issued and outstanding IAMGold shares in a subsequent acquisition transaction. The tax treatment of a subsequent acquisition transaction to a U.S. Holder will depend upon the manner in which the subsequent acquisition transaction is carried out, and may or may not result in the recognition of taxable gain.

	Distributions on Golden Star Shares

      Subject to the discussion under “Passive Foreign Investment Company” below, the gross amount of distributions, if any, payable on our shares generally will be treated as a foreign source dividend to the extent paid out of current or accumulated earnings and profits, and generally will be “passive income” for U.S. foreign tax credit purposes. A distribution on our shares in excess of current or accumulated earnings and profits will be treated as a tax-free return of capital to the extent of the U.S. Holder’s adjusted tax basis in such shares and, to the extent in excess of adjusted basis, as capital gain. See “Sale or Other Disposition of Golden Star Shares,” below.

      Canadian withholding tax on dividend distributions paid by us to a U.S. Holder is generally reduced to 15% pursuant to the U.S.-Canada tax treaty in the case of U.S. Holders who are eligible for benefits under the U.S.-Canada tax treaty. U.S. Holders generally may treat the amount of any Canadian income taxes withheld from distributions with respect to the common shares either as a deduction from their gross income or as a dollar-for-dollar credit against their U.S. Federal income tax liability, subject to numerous and complex limitations and restrictions, which must be determined and applied on an individual basis by

	Sale or Other Disposition of Golden Star Shares

      Subject to the discussion below under “Passive Foreign Investment Company,” a U.S. Holder who sells or otherwise disposes of our shares in a taxable disposition will recognize gain or loss equal to the difference, if any, between the U.S. dollar value of the amount realized on such sale or other taxable disposition and the U.S. Holder’s adjusted tax basis in such shares. Any such gain or loss will be capital gain or loss, and will be long-term capital gain or loss if the holding period for our shares is more than one year at the time of the sale or other disposition. Any such gain or loss will generally be treated as U.S. source income for U.S. foreign tax credit purposes, although special rules apply to U.S. Holders who have a fixed place of business outside the United States to which the gain is attributable. Special considerations may apply to a U.S. Holder who receives foreign currency in connection with a sale or other taxable disposition of our shares.

	Passive Foreign Investment Company

      If Golden Star were or were to become a PFIC for U.S. Federal income tax purposes, U.S. Holders of our shares would be subject to a special, adverse tax regime (different in significant respects from that described above). If we were, or were to become, a PFIC for any year in which a U.S. Holder owns our shares, gain on a disposition or deemed disposition by the U.S. Holder of our shares, and the amount of distributions, if any, payable on our shares, would be subject to tax as an “excess distribution” at the highest marginal rates applicable to ordinary income, and would be subject to interest charges to reflect the value of the U.S. income tax deferral, unless the U.S. Holder has timely made a “mark-to-market” election or a “qualified electing fund” election. In general terms, we will be a PFIC for any tax year in which either (i) 75% or more of our gross income is passive income or (ii) the average percentage, by fair market value, of our assets that produce or are held for the production of passive income is 50% or more. “Passive income” includes, for example, dividends, interest, certain rents and royalties, certain gains from the sale of stock and securities, and certain gains from commodities transactions.

      We do not believe that we are, nor do we expect to become, a PFIC. However, there can be no assurance that Golden Star’s determination concerning our PFIC status will not be challenged by the IRS. There is also a possibility that we could become a PFIC in the future as a result of future financial results.

Non-U.S. Holders

	Consequences of Exchanging IAMGold Shares Pursuant to the Offer

      If the exchange of IAMGold shares for our shares pursuant to the offer qualifies as an exchange pursuant a “reorganization” within the meaning of Section 368(a)(1) of the Code, Non-U.S. Holders generally will not recognize gain or loss for U.S. Federal income tax purposes upon the receipt of our shares in the exchange. However, a Non-U.S. Holder may recognize gain on the receipt of cash in lieu of fractional Golden Star shares if either of the following conditions applies:

	•	Such gain is attributable to an office or other fixed place of business in the United States and, if a treaty applies, such gain is attributable to a permanent establishment or fixed base the Non-U.S. Holder maintains in the United States; or
	•	The Non-U.S. Holder is an individual who is present in the United States for 183 days or more during the taxable year of disposition, has a tax home in the United States, and certain other requirements are met.

      If the exchange of IAMGold shares for our shares fails to qualify as an exchange pursuant to a reorganization under Section 368(a)(1) of the Code, a Non-U.S. Holder would not recognize gain on the exchange for U.S. Federal income tax purposes unless either one of the two conditions described immediately above is satisfied.

	Acquisition of IAMGold Shares Not Exchanged Pursuant to the Offer

      We may acquire IAMGold shares not exchanged in the offer pursuant to a compulsory acquisition. The consequences to a Non-U.S. Holder of any compulsory acquisition will depend upon the consideration issued by us in the compulsory acquisition. To the extent the IAMGold shares are acquired for our shares, the consequences to a Non-U.S. Holder should generally be similar to the consequences to a Non-U.S. Holder of exchanging IAMGold shares for our shares pursuant to the offer. Such consequences will depend in part upon whether the exchange qualifies as an exchange pursuant to a reorganization under Section 368(a)(1) of the Code. See “Non-U.S. Holders — Consequences of Exchanging IAMGold shares Pursuant to the Offer.”

      A Non-U.S. Holder that exercises dissent rights and receives cash for its IAMGold shares will recognize gain (based on the difference between the cash received and the holder’s adjusted tax basis in the IAMGold shares exchanged) only if one of the two conditions apply that are described (and bulleted) in the discussion captioned “Non-U.S. Holders — Consequences of Exchanging IAMGold Shares Pursuant to the Offer.”

      If we do not acquire all of the IAMGold shares pursuant to the offer or by means of a compulsory acquisition, we may propose other means of acquiring the remaining issued and outstanding IAMGold shares in a subsequent acquisition transaction. The consequences of a subsequent acquisition will depend upon the circumstances of the subsequent acquisition. In general, however, a Non-U.S. Holder would not recognize gain in a subsequent acquisition unless one of the two conditions apply that are described (and bulleted) in the discussion captioned “Non-U.S. Holders — Consequences of Exchanging IAMGold Shares Pursuant to the Offer.”

	Sale or Other Disposition of Golden Star Shares

      In general, a Non-U.S. Holder will not be subject to U.S. Federal income tax on any gain realized upon the sale or other disposition of our shares unless:

	•	Such gain is attributable to an office or other fixed place of business in the United States and, if a treaty applies, such gain is attributable to a permanent establishment or fixed base the Non-U.S. Holder maintains in the United States; or
	•	The Non-U.S. Holder is an individual who is present in the United States for 183 days or more during the taxable year of disposition, has a tax home in the United States, and certain other requirements are met.

Information Reporting and Backup Withholding

      U.S. Holders of IAMGold shares may be subject to information withholding and may be subject to backup withholding, currently at up to a 28% rate, on cash payments received in exchange for IAMGold shares. Payments of distributions on, or the proceeds from a sale or other disposition of, our shares paid within the U.S. may be subject to information reporting and may be subject to backup withholding. Payments of distributions on, or the proceeds from the sale of, our shares to or through a foreign office of a broker generally will not be subject to backup withholding, although information reporting may apply to those payments in certain circumstances.

      Backup withholding will generally not apply, however, to a U.S. Holder who:

	•	furnishes a correct taxpayer identification number and certifies that he, she or it is not subject to backup withholding on the IRS Form W-9 (or substitute form); or
	•	is otherwise exempt from backup withholding.

      Non-U.S. Holders generally will not be subject to U.S. information reporting or backup withholding. However, such holders may be required to provide certification of non-U.S. status (generally, on IRS

Table of Contents

      Backup withholding is not an additional tax. Any amounts withheld from a payment to a holder under the backup withholding rules may be credited against the holder’s U.S. Federal income tax liability, and a holder may obtain a refund of any excess amounts withheld by filing the appropriate claim for refund with the IRS in a timely manner and furnishing any required information.

FINANCIAL ADVISOR, DEALER MANAGER, DEPOSITARY AND INFORMATION AGENT

      BMO Nesbitt Burns Inc. has been retained as our financial advisor. In addition, BMO Nesbitt Burns Inc. and Harris Nesbitt Corp., its U.S. affiliate, have been retained to act as dealer manager in connection with the offer. In Canada, BMO Nesbitt Burns Inc. may form a soliciting dealer group comprised of members of the Investment Dealer Association of Canada and members of the stock exchanges in Canada to solicit acceptances of the offer. We will reimburse the dealer manager for its reasonable out-of-pocket expenses, including reasonable attorneys’ fees, and have also agreed to indemnify the dealer manager against certain liabilities and expenses in connection with the offer, including certain liabilities under applicable securities laws. We have also retained Innisfree M&A Incorporated to act as Information Agent in connection with the offer. Innisfree will receive reasonable and customary compensation from us for services performed in connection with the offer, will be reimbursed for certain out-of-pocket expenses and will be indemnified against certain liabilities, including liabilities under securities laws and expenses incurred in connection therewith.

      We have also retained CIBC Mellon Trust Company to act as depositary under the offer for the receipt of the certificates in respect of the IAMGold shares and related letters of transmittal and notices of guaranteed delivery deposited under the offer. The depositary will receive reasonable and customary compensation from us for its services in connection with the offer and will be reimbursed for certain out-of-pocket expenses. We have also agreed to indemnify the depositary against certain liabilities and expenses in connection with the offer, including liabilities under applicable securities laws.

OFFEREES’ STATUTORY RIGHTS

      Securities legislation in certain of the provinces and territories of Canada provides securityholders of IAMGold with, in addition to any other rights they may have at law, rights of rescission or damages, or both, if there is a misrepresentation in a circular or a notice that is required to be delivered to such securityholders. However, such rights must be exercised within the time limit prescribed by the securities legislation of the securityholder’s province or territory. Holders of IAMGold shares should refer to any applicable provisions of the securities legislation of their province or territory for the particulars of those rights or consult with a lawyer.

COMPARISON OF SHAREHOLDER RIGHTS

Comparison of Rights of Holders of Golden Star Common Shares and IAMGold Common Shares

      Golden Star and IAMGold are both corporations organized in Canada and the rights of the respective shareholders are governed by the Canada Business Corporations Act, referred to as the “CBCA”, and other laws of Canada, and the respective articles and by-laws. Following consummation of the offer, IAMGold shareholders who exchange their shares will become our shareholders and as such their rights will be governed by Canadian law and our articles of arrangement and by-laws.

      The following is a summary of the material differences between the rights of holders of IAMGold shares and the rights of holders of our shares. Since both companies are governed by the CBCA, these differences arise from disparities between the respective corporate charters and by-laws of IAMGold and

ACCOUNTING TREATMENT OF OFFER

      As required by Canadian and United States generally accepted accounting principles, Golden Star has used purchase accounting rules in its pro forma financial statements. Purchase accounting specifies that the acquired entity’s assets and liabilities be revalued to their fair value prior to consolidating the acquired entity with the acquiring entity.

      Once fair value is established for the acquired entity’s assets and liabilities, the excess of the purchase price over the net asset value is recorded as goodwill in the consolidated financial statements.

      Fair value is estimated by various techniques including analysis of expected future cash flows and market comparables. Purchase accounting also requires that adjustments be made to the acquired entity’s financial statements to reconcile any differences in accounting policies between the two entities.

INTERESTS OF CERTAIN PERSONS IN THE OFFER

Interests of Directors, Officers and Affiliates

      Investors should be aware that some Golden Star and IAMGold executive officers and directors may have interests in the proposed transaction that may be different from, or in addition to, their interests as stockholders of Golden Star. Note that the information presented below related to IAMGold is based on public information and has not been verified by us. As a result, we do not make any representation as to the accuracy or completeness of such IAMGold information.

	Stock Options

      Under Golden Star’s Second Amended and Restated 1997 Stock Option Plan, in the event of a change of control, all options outstanding shall become immediately exercisable. “Change of control” is defined as the occurrence of any of the following: (i) the sale, lease, transfer, conveyance or other disposition, in one or a series of related transactions, of all or substantially all of the assets of the Corporation to any “person” or “group” (as such terms are used in Sections 13(d)(3) and 14(d)(2) of the Securities Exchange Act of 1934), (ii) any person or group, is or becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act, except that a person shall be deemed to have “beneficial ownership” of all shares that any such person has the right to acquire, whether such right is exercisable immediately or only after the passage of time), directly or indirectly, of more than 50% of the total voting power of the voting stock of Golden Star, including by way of merger, consolidation or otherwise or (iii) during any period of two consecutive years, individuals who at the beginning of such period constituted the Board of Directors (together with any new directors whose election by such Board of Directors whose nomination for election by the shareholders of Golden Star was approved by a vote of a majority of the directors of Golden Star, then still in office, who were either directors at the beginning of such period or whose election or nomination for election was previously so approved) cease for any reason to constitute a majority of the Board of Directors, then in office.

      Golden Star understands that IAMGold has in place a Share Incentive Plan that includes a share option plan under which if a “take-over bid” (within the meaning of the Securities Act (Ontario)) is made for the shares of IAMGold, then the IAMGold directors may permit all options outstanding to become immediately exercisable in order to permit IAMGold shares issuable under such options to be tendered to such bid.

	Employment Agreements

      We have agreed to enter into employment agreements with Messrs. Bradford, Marter, Gray, Jones and Higson-Smith. Each agreement has a one year term and is automatically renewed for successive one year periods unless terminated by either party. If terminated by us without cause, or by the executive for good reason as defined in the agreement, each executive would receive a lump-sum payment equal to one year salary, target bonus and benefits, except for Mr. Bradford who would receive two years salary, target bonus and benefits.

      If the executive’s employment is terminated without cause by us or by the executive for good reason following a change in control, each executive will be entitled to a lump sum payment equal to two years salary, target bonus and benefits, except for Mr. Bradford, who would receive three years salary, target bonus and benefits. A change in control occurs if any of the following four circumstances occurs: (i) any “person” or “group” (within the meaning of Sections 13(d) and 14(d)(2) of the Exchange Act), other than a trustee or other fiduciary holding securities under an employee benefit plan of the Company is or becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of more than thirty percent (30%) of the then outstanding voting stock of the Company; or (ii) persons who are Incumbent Directors cease to constitute a majority of the Board of Directors; or (iii) the stockholders of the Company approve a merger or consolidation of the Company with any other corporation, other than a merger or consolidation which would result in the voting securities of the

      Golden Star understands that IAMGold has employment and management agreements with Messrs. Pugliese, Conway, Edey, Phillips, Olmsted and Jones. These agreements contain change of control provisions that provide that, under certain specified circumstances, a change in control of IAMGold is deemed to constitute termination of the applicable person by IAMGold other than for cause, unless waived by such person. These agreements contain a provision that if any such person is terminated by IAMGold other than for cause, Mr. Pugliese is entitled to 12 months base salary, and Messrs. Conway, Edey, Phillips, Jones and Olmsted are entitled to 24 months base salary.

      We understand that if the employment of the relevant IAMGold executive officers terminates following the offer under circumstances entitling the executive officers to severance under the employment agreements, the approximate cash amount of the severance payments that would be paid under such agreements (not including any gross-up payments) would be up to Cdn$3 million.

	Other

      During the year 2003, Golden Star obtained legal services from a legal firm, to which Mr. MacGregor, our director and Chairman of the Board, is counsel. The total value of all legal services provided in 2003 was Cdn$169,000. The same law firm continues to provide services to us, including services related to the offer. Mr. MacGregor performed no services (other than services as a director of Golden Star for which he was compensated) for us for which he or the firm received compensation. He did not receive during 2003 and will not receive during 2004 any economic benefit directly or indirectly from payments made by Golden Star for the services performed by the firm.

LIMITATION OF LIABILITY AND INDEMNIFICATION

      We have entered into agreements with our directors and officers indemnifying such directors and officers to the extent permitted by the CBCA, and our by-laws. Our by-laws provide that we will indemnify any such person in such circumstances as the CBCA or law permits or requires.

      Our ability to indemnify our directors and officers is governed by section 124 of the CBCA. Under this provision, we may indemnify a director or officer, a former director or officer or another individual who acts or acted at our request as a director or officer or in a similar capacity, of another entity (the “individual”) against all costs, charges, and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by the individual in respect of any civil, criminal, administrative, investigative or other proceeding in which the individual is involved by reason of their association with us or such other entity. However, we may not indemnify an individual unless the individual:

	a. acted honestly and in good faith with a view to the best interests of our or such other entity for which the individual acted as director or officer or in a similar capacity at our request, as the case may be; and
	b. in the case of criminal or administrative action or proceeding that is enforced by a monetary penalty, the individual had reasonable grounds for believing that the individual’s conduct was lawful.

      We may advance funds to a director, officer or other individual for the costs, charges and expenses of a proceeding referred to above. The individual shall repay the amount advanced if the individual does not fulfill the conditions of sections (a) and (b) above.

Table of Contents

      With the approval of a court, we may indemnify an individual, or advance funds, in respect of an action by or on our behalf or by or on behalf of another entity to procure a judgment in our favor to which the individual is made a party because of the individual’s association with us or such other entity against all costs, charges and expenses reasonably incurred by the individual in connection with such action if the individual fulfills the conditions in clauses (a) and (b) above.

      In addition to the right to indemnification set forth in the agreements with our directors and our by-laws, the CBCA provides that an individual is entitled to indemnification from us in respect of all costs, charges and expenses reasonably incurred by the individual in connection with the defense of any civil, criminal, administrative, investigative or other proceeding to which the individual is subject because of the individual’s association with us or such other entity, if the individual seeking indemnity:

	a. was not judged by the court of other competent authority to have committed any fault or omitted to do anything that the individual ought to have done; and
	b. fulfills the conditions set out in clauses (a) and (b) above.

      We maintain a directors’ and officers’ liability insurance policy which insures directors and officers for losses as a result of claims based upon the acts or omissions of our directors and officers, including liabilities arising under the Securities Act, and also reimburses us for payments made pursuant to the indemnity provisions under the CBCA.

      Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the registrant pursuant to the foregoing provisions, the registrant has been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

ANNEX A

INFORMATION CONCERNING GOLDEN STAR

      The following information should be read in conjunction with the information concerning Golden Star appearing elsewhere in the prospectus and incorporated by reference in the prospectus. All references in this Annex A to “Golden Star” or “we” mean Golden Star and its consolidated subsidiaries, or any one or more of them as the context requires.

Overview

      We are a Canadian international gold mining and exploration company, focused primarily on mining, mine development and exploration in Ghana, West Africa. We produced 174,315 ounces of gold in 2003 at a cash operating cost of $166 per ounce, and 47,202 ounces in the first quarter of 2004 at a cash operating cost of $181 per ounce. We expect to produce from 185,000 to 210,000 ounces in 2004 at a cash operating cost of $200 to $225 per ounce.

      We own 90% interests in two properties in Ghana, the Bogoso/ Prestea open pit mine and related properties and the Wassa project. We operate the Bogoso/ Prestea mine, with ore mined at the Prestea property being processed at the Bogoso processing plant. We commenced development of the Wassa mine in mid-2003. We expect to begin commercial production in the third quarter of 2004 by milling material from the existing heap leach pads, possibly supplemented by higher grade ore from the open pit mine, with full production from the open pit mine anticipated in 2005. We also own a 61% managing interest in the currently inactive Prestea underground mine. As part of our $21 million 2004 exploration program, we plan to spend $6.6 million in exploration underground in 2004 as part of our effort to determine whether the underground mine can be reactivated on a profitable basis.

      We also hold interests in gold exploration properties in Ghana, Sierra Leone, Mali, Suriname, and French Guiana.

Business Strategy and Development

      Our business and development strategy since 1999 has been to focus primarily on the acquisition of gold properties in Ghana and on the exploration, development and operation of these properties. Given our significant mineral resource position at Bogoso/ Prestea, we plan to increase production by adding a carbon-in-leach plant at Bondaye and are completing further technical studies regarding the addition to the existing Bogoso plant of a bio-oxidation circuit. At our Wassa property, we expect to commence production in the third quarter of 2004 by processing material from the existing heap leach pads left by the former owner. We plan to commence full ore production from the Wassa open pit mine in 2005. If our expansion and development plans are realized as expected, our annualized production rate should exceed 350,000 ounces of gold in 2005. However, there can be no assurance that development and start-up will be completed as anticipated or that our production goals will be achieved.

      Our objective is to grow our business to become a profitable intermediate gold producer (which we understand to be a producer with annual production from 300,000 to 1 million ounces), with an expanding presence in West Africa. In addition to our increases in production as described above, we have been actively investigating the acquisition of producing, development and advanced stage exploration gold properties and companies. These efforts have culminated in our offer to acquire IAMGold. During 2004 we have significantly increased our exploration activities and expenditures around our mines and on our current exploration properties, primarily in Ghana, with planned expenditures of approximately $21 million in 2004 compared to $8.5 million in 2003.

OUR PROPERTIES

Bogoso/ Prestea

      We own 90% of and operate the Bogoso/ Prestea gold mining and milling operation located along the Ashanti Gold Belt in southwestern Ghana. The property consists of several open pit mines and a nominal 6,000 tonne per day carbon-in-leach mill and processing plant. We hold the property under renewable mining leases granted by the Government of Ghana, terminating from 2017 to 2031. In 2003 Bogoso/ Prestea produced 174,315 ounces, an increase over 2002 production due primarily to higher than average ore grades and improved recoveries. Historical and forecast production from Bogoso/ Prestea are shown on the Gold Production and Cash Costs table below.

      Following the receipt of necessary permits, we expect to commence construction in the fourth quarter of 2004 of the Bondaye carbon-in-leach plant that we acquired in 2003. We plan that the Bondaye plant will be completed in mid-2005 at a cost of approximately $17 million, which should approximately double production capacity at Bogoso/ Prestea. Overall production from Bogoso/ Prestea should double by 2006. We also plan to upgrade the Bogoso/ Prestea truck fleet during 2004 at a cost of approximately $12 million and to expand the truck fleet in 2005 at a cost of approximately $15.5 million to increase the mining rate once the Bondaye plant commences operations.

      We continue technical work for the proposed Bogoso plant bio-oxidation (BIOX) circuit, which is currently estimated to cost approximately $25 million. Subject to receiving necessary permits and approvals, construction could commence in early 2005 and be completed by year-end 2005.

      The Government of Ghana owns the remaining 10% of Bogoso/ Prestea. As required by the law of Ghana for all mining operations, the Government has a carried interest under which it receives 10% of any future dividends from the subsidiaries owning the Bogoso/ Prestea mine, following repayment of all capital, and has no obligation to contribute development or operating expenses. The Government of Ghana also receives a royalty based on total revenues earned from the lease area. For the last three years, we have paid a royalty equal to 3% of our revenues from Bogoso/ Prestea.

Wassa

      Our 90% owned Wassa gold mine development property is also located in southwestern Ghana, approximately 35 kilometers east of Bogoso/ Prestea. Wassa was operated by its former owners as a conventional open pit, heap leach gold operation and was shut down in 2001. We acquired the Wassa property in 2002, completed a feasibility study for its redevelopment as an open pit, carbon-in-leach operation in July 2003 and commenced development in mid-2003. We plan to produce approximately 50,000 to 55,000 ounces in the third and fourth quarters of 2004 primarily by milling material from the existing heap leach pads at an estimated cash operating cost of $200 to $240 per ounce. Once the material from the heap leach pads is exhausted in 2005, and we begin processing ore mined from the open pit, we expect an annualized production rate at Wassa to average approximately 140,000 ounces at an average cash operating cost of about $200 per ounce for an initial mine life of four years, based on current reserves.

      Construction and development costs at Wassa are projected at approximately $26 million, excluding mobile equipment. Development is expected to be completed in the third quarter 2004. We expect to incur approximately $17 million of additional capital cost in 2005 to acquire a mining fleet, for which we have secured third party financing.

      We hold the Wassa property under a renewable mining lease expiring in 2022. The Government of Ghana has a 10% carried interest in Wassa.

RECONCILIATION OF CASH OPERATING COST PER OUNCE

      In this prospectus, the terms “total cash cost” and “cash operating cost” are used on a per ounce of gold basis. Total cash cost per ounce is equivalent to mining operations expense for the period as found on the Consolidated Statements of Operations, divided by the number of ounces of gold sold during the period. Cash operating cost per ounce is equivalent to mining operations expense for the period less production royalties, divided by the number of ounces of gold sold during the period. Set forth below are these reconciliations for the periods stated:

		Year Ended				Three Months Ended
		December 31,				March 31,
		2003				2004
		(Dollar figures in thousands,
		except per ounce amounts)
Mining operations expense		$	32,125			$	9,125
Less royalties			3,222				582
Cash operating expense		$	28,903			$	8,543
Gold sold (oz)			174,315				47,202
Cash operating cost per ounce ($)			166				181

      We have included total cash cost and cash operating cost information to provide investors with information about the cost structure of our mining operations. We use this information for the same purpose and for monitoring the performance of our operations. This information differs from measures of performance determined in accordance with GAAP in Canada and the United States and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. These measures are not necessarily indicative of operating profit or cash flow from operations as determined under GAAP and may not be comparable to similarly titled measures of other companies.

      All figures in this table are on a 100% basis, which represents our current beneficial interest in gold production and revenues. Once all capital invested in a Ghanaian subsidiary has been repaid, the Government of Ghana would receive 10% of any dividends declared by the Ghanaian subsidiary.

MINERAL RESERVES AND RESOURCES

Proven and Probable Reserves

      Our proven and probable mineral reserves are estimated in conformance with definitions set out in Canada’s National Instrument 43-101. We have filed on SEDAR (www.sedar.com) Technical Reports on our mineral reserves for Bogoso/Prestea and Wassa as required in Canada’s National Instrument 43-101.

      Our proven and probable mineral reserves as of December 31, 2003 have been estimated at an economic cut-off grade based on a gold price of $325 per ounce.

      As used in “Mineral Reserves and Resources,” “g/t” means grams per tonne.

(1)	Tonnes of mineral reserves are net of a 5% dilution allowance for mining, to account for losses resulting from planned mining methods, and a 98% ore recovery factor.
(2)	Calculation of contained ounces includes adjustments due to rounding.
(3)	Approximately 68% of the 2003 Bogoso/ Prestea mineral reserves are refractory ore. The estimated recovery rates used in our mineral reserve calculations in 2003 ranged from 65% to 85% for oxides and other less-refractory ores, and from 78% to 85% for refractory ore. The estimated cut-off grades used in 2003 ranged from 0.7 g/t to 1.8 g/t for oxide ore and other less-refractory ores and from 1.5 g/t to 2.3 g/t for refractory ore. Included in the December 31, 2003 proven reserves is 0.8 million tonnes at an average grade of 2.4 g/t in stockpiles. Included in probable reserves are the Mampon property reserves of 0.9 million tonnes at an average grade of approximately 5.6 g/t containing approximately 162,000 ounces of gold, acquired in June 2003.
(4)	Wassa reserves are non-refractory. The estimated recoveries used in mineral reserve calculations in 2003 ranged from 92% to 93%. The estimated cut-off grades used in 2003 range from 0.5 g/t to 0.6 g/t. The mineral reserves include 4.2 million tonnes of material grading 0.7 g/t remaining on the leach pads from the previous operation.

Non-Reserves — Measured and Indicated Mineral Resources

	Cautionary Note to US Investors Concerning Estimates of Measured and Indicated Mineral Resources

      This section uses the terms “measured mineral resources” and “indicated mineral resources”. We advise US investors that while those terms are recognized and required by Canadian regulations, the SEC does not recognize them. U.S. investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into mineral reserves.

      Our measured and indicated mineral resources do not include proven and probable mineral reserves, and have been estimated in conformance with definitions set out in Canada’s National Instrument 43-101. We have filed on SEDAR (www.sedar.com) Technical Reports on our mineral reserves and mineral resources (mineral resources stated in the Technical Reports include mineral reserves) for Bogoso/Prestea and Wassa as required in Canada’s National Instrument 43-101.

Non-Reserves — Inferred Mineral Resources

	Cautionary Note to US Investors Concerning Estimates of Inferred Mineral Resources

This section uses the term “inferred mineral resources”. We advise US investors that while this term is recognized and required by Canadian regulations, the SEC does not recognize it. “Inferred mineral resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resources will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources could not form the basis of feasibility or other economic studies. US investors are cautioned not to assume that part or all of the inferred mineral resource exists, or is economically or legally mineable.

      Our inferred mineral resources do not include proven and probable mineral reserves or measured and indicated mineral resources, and have been estimated in conformance with definitions set out in Canada’s National Instrument 43-101. We have filed on SEDAR (www.sedar.com) Technical Reports on our

EXPLORATION

      Most of our exploration efforts in 2003 were focused on the Prestea Underground, Prestea, Wassa and the Akropong Trend properties in Ghana. We spent approximately $8.5 million in exploration activities during 2003, including $2.2 million at Wassa establishing mineral reserves in the existing pits and in areas outside the pits, $3.1 million at the Prestea Underground, including underground care and maintenance costs, $2.3 million on exploration projects outside the Wassa and Bogoso/ Prestea areas and $0.9 million developing new mineral reserves in the Plant North area. Exploration spending during 2003 was less than expected due to a shortage of drill rigs in Ghana. Increases in exploration activity in Ghana by us and our competitors have adversely impacted drill rig availability and as a result some of our planned work was delayed, including drilling at the Prestea Underground which was delayed several months.

      During 2004, we plan to spend approximately $21 million on gold exploration, of which approximately $4.9 million was spent in the first quarter 2004. Approximately $6 million will be used to evaluate surface projects in and around Bogoso/ Prestea including the Akropong Trend and Dunkwa properties. Approximately $6.6 million is planned for the continued exploration efforts at the Prestea Underground project, $2.5 million is scheduled for the Wassa area, $2.4 million is expected to be spent on the properties in Sierra Leone and Mali, both in West Africa, $1.7 million is expected to be used to identify and evaluate projects in South America, including some of Guyanor’s holdings, and $1.6 million is planned for our project generation program.

      Golden Star and Guyanor announced in late May plans to make certain changes to the ownership and management of Guyanor. The impact of these changes is unlikely to be material to Golden Star.

DESCRIPTION OF SECURITIES

      Our authorized capital includes an unlimited number of common shares and an unlimited number of first preferred shares, without nominal or par value, issuable in series.

Common Shares

      As of June 8, 2004, there were 138,646,013 Golden Star common shares outstanding.

	Dividend Rights

      Holders of our common shares may receive dividends when, as and if declared by our board on the common shares, subject to the preferential dividend rights of any other classes or series of our shares. In no event may a dividend be declared or paid on the common shares if payment of the dividend would cause the realizable value of our assets to be less than the aggregate of its liabilities and the amount required to redeem all of the shares having redemption or retraction rights, which are then outstanding.

	Voting and Other Rights

      Holders of our common shares are entitled to one vote per share, and in general, all matters will be determined by a majority of votes cast.

	Liquidation

      In the event of any liquidation, dissolution or winding up of Golden Star, holders of the common shares have the right to a ratable portion of the assets remaining after payment of liabilities and liquidation preferences of any preferred shares or other securities that may then be outstanding.

Table of Contents

	Redemption

      Our common shares are not redeemable or convertible.

	Rights Agreement

      Rights to purchase our common shares have been issued to holders of our common shares under a rights agreement between us and CIBC Mellon Trust Company. One right is attached to each common share. If the rights become exercisable following the occurrence of certain specified events, each right will entitle the holder, within certain limitations, to purchase one common share at an exercise price equal to three times the market price of the common share, as determined under the terms of the agreement. In certain events (including when a person or group becomes the beneficial owner of 20% or more of any class of our voting shares without complying with the “permitted bid” provisions of the rights agreement or without the approval of our board of directors), exercise of the rights would entitle the holders of the rights (other than the acquiring person or group) to acquire that number of our common shares having an aggregate market price on the date of the event equal to twice the exercise price of the rights for an amount in cash equal to the exercise price. Accordingly, exercise of the rights may cause substantial dilution to a person who attempts to acquire us. The rights, which expire in 2007 (unless extended as provided in the rights agreement), may be redeemed at a price of Cdn$0.00001 per right at any time until a person or group has acquired 20% of our common shares, except as otherwise provided in the rights agreement. The rights agreement may have certain anti-takeover effects.

	Other Provisions

      All outstanding common shares are, and the common shares to be issued in connection with the offer, if issued in the manner described in this Circular, will be, fully paid and non-assessable.

PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS OF GOLDEN STAR RESOURCES LTD.

DESCRIPTION OF OFFER TO PURCHASE IAMGOLD CORPORATION

      Golden Star Resources Ltd. (“Golden Star”, the “Company”, “us”, “we”) announced on May 27, 2004 a proposed business combination with IAMGold Corporation (“IAMGold”). On June 9, 2004 we commenced our offer to exchange 1.15 Golden Star common shares for each common share of IAMGold, or approximately 171.7 million of Golden Star common shares for approximately 149.3 million IAMGold common shares, assuming all in-the-money options to purchase IAMGold common shares are exercised.

      Assuming all IAMGold shares are exchanged in this offer, immediately following the exchange, approximately 48% of the shares would be held by current Golden Star shareholders and approximately 52% of the shares would be held by current IAMGold shareholders, calculated on a fully diluted basis. As the relative share ownership of the two groups of shareholders is similar, it is expected that Golden Star’s board of directors and management will retain their positions in the combined entity and Golden Star’s corporate office will continue to be the headquarters of the combined entity, Golden Star is considered to be the acquirer for the purposes of purchase accounting. In accordance with this assumption, IAMGold’s assets and liabilities have been restated in the pro forma financial statements presented below, to reflect their estimated fair values as of the date of the announcement of the proposed acquisition.

      The pro forma financial statements are based upon a Golden Star common share price of $5.10, this amount being the average closing common share price of Golden Star three days before and after the day of the date of the public announcement of Golden Star’s proposed business combination with IAMGold.

      As a consequence of the nature of the transaction, there may be, and likely will be, actions and other events or changes initiated by IAMGold that would significantly change purchase prices and purchase price allocations. Also, Golden Star has not had access to proprietary and confidential corporate financial and other information of IAMGold and has not had an opportunity to undertake any due diligence procedures. Such information and procedures may provide Golden Star with additional information that could materially affect the purchase price paid for the acquisition of IAMGold, the purchase price allocation and, accordingly, the assumptions and pro forma adjustments. Identified factors which may have a significant impact on the basis and results of the combinations are described in Note 3 of the accompanying notes to the Pro Forma Consolidated Financial Statements.

      The combination of Golden Star and IAMGold is subject to, among other things, regulatory approval. The fair value of IAMGold’s assets and liabilities will ultimately be determined after the completion of the transaction. Therefore, it is likely that the fair values of assets and liabilities will vary from those shown and the differences may be material.

      The preliminary allocation of the purchase price ($000s) summarized in the table below is subject to change:

Purchase price
	149,266,712 IAMGold shares (1)		$	874,877
	Estimated acquisition costs			10,000
			$	884,877

	Share purchase loans			266
	Deferred stock-based compensation			3,748

1.	The amount shown is an estimated price based on the number of IAMGold shares outstanding on June 4, 2004 and assumes the exercise of all IAMGold options where the market price on June 4, 2004 exceeds such option’s exercise price, or “in-the-money IAMGold options.”
2.	The allocation shown above assumes IAMGold will pay a $23 million break fee to Wheaton River. If Wheaton River were to combine with Coeur d’Alene, we would then receive a $26 million payment in lieu of the break fee from Coeur d’Alene per an agreement between us and Coeur d’Alene. See “Pre-Offer Agreement with Coeur d’Alene.” If we receive the $26 million payment from Coeur d’Alene, our cash would be $49 million higher and the goodwill would be $49 million lower than shown above.

BASIS OF PRESENTATION

      Set out below are the unaudited consolidated pro forma statements of operation for the year ended December 31, 2003 and three months ended March 31, 2004 and the unaudited consolidated pro forma balance sheet of Golden Star at March 31, 2004. These statements have been prepared by the management of Golden Star to assist you in your analysis of the financial effects of the proposed business combination of Golden Star and IAMGold.

      The Golden Star information has been derived from our historical unaudited financial statements as of and for the three months ended March 31, 2004 and from our historical audited financial statements for the year ended December 31, 2003. Our historical data was prepared using accounting principles generally accepted in Canada.

      IAMGold’s information has been compiled solely from publicly available information for the same periods as Golden Star’s, as described above. IAMGold has not provided us access to their detailed accounting records nor has IAMGold assisted us in preparing any of the data contained in the pro forma financial statements shown below. IAMGold’s historical data was prepared using accounting principles generally accepted in Canada.

      It is management’s opinion that these pro forma consolidated financial statements include all adjustments necessary for the fair presentation, in all material respects, of the transaction described above in accordance with Canadian generally accepted accounting principles applied on a basis consistent with Golden Star’s accounting policies.

      The pro forma consolidated financial statements are not intended to reflect the results of operations or the financial position of Golden Star which would have actually resulted had the proposed transactions been effected on the dates indicated. Further, the pro forma financial information is not necessarily indicative of the results of operations that may be obtained in the future. The unaudited pro forma consolidated financial statements should be read in conjunction with the historical financial statements and notes thereto of Golden Star and IAMGold, described above.

      The pro forma consolidated financial statements assume that IAMGold will combine with Golden Star, and Wheaton River will not combine with Coeur d’Alene. As a result, IAMGold would be required to pay a $23 million break fee to Wheaton River. If Wheaton River agrees to combine with Coeur d’Alene, rather than IAMGold paying a $23 million break fee, we would receive a $26 million break fee from Coeur d’Alene. The accounting effect of this event on the pro forma financial statements would be a $49 million increase in the combined entity’s cash and a $49 million reduction in goodwill on the balance sheet of the combined entity both at March 31, 2004 under Canadian GAAP and at December 31, 2003 under US GAAP. This change would not affect net income or earnings per share.

      The pro forma consolidated financial statements include the following pro forma assumptions and adjustments:

	(a) The unaudited pro forma consolidated financial statements have been compiled using the significant accounting policies as set out in the audited financial statements of Golden Star for the year ended December 31, 2003.
	(b) The December 31, 2003 and the March 31, 2004 pro forma statements of operations assume that the acquisition occurred on January 1, 2003. The March 31, 2004 balance sheet assumes the acquisition occurred at March 31, 2004.

F-11

---

Table of Contents

	(c) All of IAMGold’s assets and liabilities have been restated where appropriate to reflect estimated fair values using purchase accounting concepts. Estimated mining property and equity investment fair values are based upon discounted cash flow analysis.
	(d) IAMGold’s transaction costs are estimated to be $5 million. Golden Star’s transaction costs and fees, including advisors, legal, accounting, exchange fees, regulatory fees, and IAMGold rationalization costs will total approximately $10 million. It is also assumed that IAMGold will pay a $23 million break fee to Wheaton River. See “Pre-Offer Agreement with Coeur d’Alene”. Assumes that in-the-money IAMGold options outstanding as of June 4, 2004 are exercised for cash and the IAMGold shares issued are exchanged for Golden Star shares.
	(e) The excess of the purchase price over the fair value of the net assets is shown as goodwill. The goodwill shown in the pro forma financial statements is based upon a preliminary analysis of the factors involved in determining fair values. The final allocation of the purchase price and the fair values of IAMGold’s assets and liabilities is subject to completion of definitive appraisals which would be carried out following completion of the acquisition.
	(f) No adjustments have been made to reflect expected synergies or cost savings of the proposed transaction.
	(g) Amortization has been adjusted to reflect adjustments of asset basis to fair value.
	(h) The impact of differences between the fair value and the tax value of assets and liabilities has been reflected in the future tax balance and the resulting impact on income tax expense has been reflected on the statements of operations.
	(i) The pro forma information has been compiled using a Golden Star common share price of $5.10 per share, being the average of the closing price on the AMEX for the three days before and after May 27, 2004, the date of announcement of Golden Star’s proposed business combination with IAMGold.
	(j) IAMGold’s 2003 and first quarter 2004 exploration costs have been capitalized as deferred exploration to correspond with Golden Star’s accounting policy.
	(k) During the first quarter of 2004, IAMGold changed its accounting policies with respect to the accounting for Asset Retirement Obligations and share options. Golden Star changed its accounting policies for Asset Retirement Obligations and share options effective January 1, 2003. Therefore, IAMGold’s statement of operations for the year ended December 31, 2003 has been restated to account for these changes in accounting policies using the information disclosed in IAMGold’s audited consolidated financial statements for the year ended December 31, 2003, and the consolidated financial statements for the three months ended March 31, 2004.
	(l) Deferred revenues related to hedge positions closed in past periods were assigned a fair value of nil and therefore the revenue recognized in IAMGold’s statements of operations has been reversed on the Golden Star pro forma statements of operation.
	(m) The gain on marketable securities recognized by IAMGold in comprehensive income is eliminated as a pro forma adjustment since the marketable securities were adjusted to fair value in the acquisition of IAMGold by Golden Star.

PART II

INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 20.	Indemnification of Officers and Directors.

      We have entered into agreements with our directors and officers indemnifying such directors and officers to the extent permitted by the CBCA, and our by-laws. Our by-laws provide that we will indemnify any such person in such other circumstance as the CBCA or law permits or requires.

      Our ability to indemnify our directors and officers is governed by section 124 of the CBCA. Under these provisions, we may indemnify a director or officer, a former director or officer or another individual who acts or acted at our request as a director or officer or in a similar capacity, of another entity (the “individual”) against all costs, charges, and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by the individual in respect of any civil, criminal, administrative, investigative or other proceeding in which the individual is involved by reason of their association with us or such other entity. However, we may not indemnify an individual unless the individual:

	a. acted honestly and in good faith with a view to the best interests of our or such other entity for which the individual acted as director or officer or in a similar capacity at our request, as the case may be; and
	b. in the case of criminal or administrative action or proceeding that is enforced by a monetary penalty, the individual had reasonable grounds for believing that the individual’s conduct was lawful.

      We may advance funds to a director, officer or other individual for the costs, charges and expenses of a proceeding referred to above. The individual shall repay the amount advanced if the individual does not fulfill the conditions of sections (a) and (b) above.

      With the approval of a court, we may indemnify an individual, or advance funds, in respect of an action by or on our behalf or by or on behalf of another entity to procure a judgment in our favor to which the individual is made a party because of the individual’s association with us or such other entity against all costs, charges and expenses reasonably incurred by the individual in connection with such action if the individual fulfills the conditions in clauses (a) and (b) above.

      In addition to the right to indemnification set forth in the agreements with our directors and our by-laws, the CBCA provides that an individual is entitled to indemnification from us in respect of all costs, charges and expenses reasonably incurred by the individual in connection with the defense of any civil, criminal, administrative, investigative or other proceeding to which the individual is subject because of the individual’s association with us or such other entity, if the individual seeking indemnity:

	a. was not judged by the court of other competent authority to have committed any fault or omitted to do anything that the individual ought to have done; and
	b. fulfills the conditions set out in clauses (a) and (b) above.

      We maintain a directors’ and officers’ liability insurance policy which insures directors and officers for losses as a result of claims based upon the acts or omissions as our directors and officers, including liabilities arising under the Securities Act of 1933, or the ’33 Act, and also reimburses us for payments made pursuant to the indemnity provisions under the CBCA.

      Insofar as indemnification for liabilities arising under the ’33 Act may be permitted to directors, officers or persons controlling the registrant pursuant to the foregoing provisions, the registrant has been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the ’33 Act and is therefore unenforceable.

Item 22.	Undertakings.

      (a) The undersigned registrant hereby undertakes:

	(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

	(i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;
	(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and

Table of Contents

	any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;
	(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

	(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
	(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

      (b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

      (c) The undersigned registrant hereby undertakes to deliver or cause to be delivered with the prospectus, to each person to whom the prospectus is sent or given, the latest annual report to security holders that is incorporated by reference in the prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Exchange Act; and, where interim financial information required to be presented by Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or cause to be delivered to each person to whom the prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the prospectus to provide such interim financial information.

      (d) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question, whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

      (e) The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11 or 13 of this Form, within one business day of receipt of request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

      (f) The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
