DYNATEC TO JOIN FNX MINING IN
AURORA PLATINUM ACQUISITION

TORONTO, ONTARIO - May 18, 2005 - FNX Mining Company Inc. (FNX-TSX/AMEX) announced today that it has agreed to sell to Dynatec Corporation (DY-TSX), its partner in the Sudbury Joint Venture, a 50% indirect interest in Aurora Platinum Corp. (ARP-TSXV) following the completion of FNX's acquisition of Aurora in exchange for approximately 7.8 million Dynatec shares, cash not to exceed $12.1 million and their share of FNX’s transaction costs.

Under the terms of the agreement between Dynatec and FNX, Dynatec will pay an amount of money (indirectly) to FNX equal to 25% of the aggregate value of the FNX common shares issued to acquire Aurora; and Dynatec will issue to FNX 3.61365 Dynatec common shares for each two FNX common shares issued to acquire Aurora, totaling approximately 7.8 million Dynatec shares and 7.2273 Dynatec share purchase warrants for each two FNX options issued in exchange for options of Aurora, with each Dynatec share purchase warrant entitling the holder to acquire one Dynatec common share at a price equal to the price of the FNX options issued divided by 7.2273 for a term equivalent to the term of the FNX options for which the particular Dynatec share purchase warrants are issued.

Aurora is a junior Canadian resource company actively exploring for nickel-copper-platinum-palladium-gold deposits in Ontario and Quebec and through various ownership interests and agreements holds an extensive land position in the prolific Sudbury Basin mining camp.

Further details of the acquisition of Aurora by FNX and Aurora’s assets can be found in FNX's news release dated May 4, 2005.  Completion of the acquisition of Aurora by FNX and the FNX sale of 50% of Aurora to Dynatec are subject to receipt of all necessary regulatory and court approvals and Aurora shareholder approval, which will be sought on June 20, 2005.
