• 8 drill holes completed so far this season, for a total of 641 meters
• Assay results received for 5 drill holes showing 0.18% average nickel grade and over 21% average magnesium grade
• Drilling is ongoing using a Winkie drill
• Awaiting permits for 6,000 meter NQ drill program to consist of 20 holes, each with a target depth of 300 meters
• 50 drill holes have been drilled to date spanning almost 10 kilometers of the 14 kilometer Deep Purple magnetic anomaly

(Newsfile Corp. - October 3, 2023) - Green River Gold Corp. (CSE: CCR) (OTC Pink: CCRRF) (the "Company" or "Green River") is pleased to announce the receipt of assay results for drill holes WK-23-04 and WK-23-05 from MSA Labs, Langley, B.C. The Company has also finished drilling hole numbers WK-23-06, WK-23-07, and WK-23-08 and is awaiting assay results from those holes. The drilling results are from the Company's 100%-owned Quesnel Nickel Project, located 40 kilometres east by road from Quesnel, British Columbia, in the prolific Cariboo Mining District in South Central British Columbia, Canada. Since late in the calendar year 2021, the Company has drilled 50 holes at various locations spanning almost 10 kilometres of the total 14-kilometre length of the Deep Purple magnetic anomaly. All of the drill holes show XRF results indicating significant nickel, magnesium, cobalt and chromium beginning at the surface of the bedrock and continuing to depth. Assays results received for 5 of the 8 holes drilled in 2023 confirm the presence of mineralization from the surface of the bedrock.

The Company is pleased to report the assay results from WK-23-04 and WK-23-05, the fourth and fifth drill holes completed in the 2023 drilling season. Comparing the results with the previously reported results for 2023, the assay results are quite similar. The nickel, magnesium, cobalt and chromium concentrations are also consistent with the 42 holes drilled in late 2021 and throughout 2022.

The drillers encountered 1.50 meters of glacial till before reaching bedrock in drill hole WK-23-04. They encountered 8.22 meters of glacial till before reaching bedrock in drill hole WK-23-05. The glacial till is similar to sediment layers at surface, which is typical in the Cariboo region. Many of the previous drill holes were drilled from rocky outcrops and encountered no glacial till. These two drill holes encountered nickel, magnesium, cobalt, and chromium in the first meter of bedrock, as did the previous 48 drill holes.

Perry Little, President and CEO of Green River comments, "We are thrilled to see the consistency and continuity of the drill results as we continue to expand the known area of mineralization. We are able to drill throughout the Winter months because of our location, only 45 minutes from our large shop in Quesnel. Pending the receipt of permits, our drilling contractor, Gold Rush Supplies Inc. is ready to drill deeper holes so we can move toward the preparation of a 43-101 resource estimate on Zone 1 in the first half of 2024."

Metallurgical testing on Zone 1 was performed by Base Metallurgical Laboratories Ltd., located in Kamloops, British Columbia in 2022. The results of the analysis revealed that the core sample contains 0.16% nickel and 0.44% sulphur. Additionally, based on weight percentages, the mineral composition is determined to be 50.7% talc, 27.1% dolomite, and 12.8% serpentine. The QEMSCAN BMA analysis was utilized to determine the mineral content and nickel distribution. The analysis indicates that the main sulphide minerals present are pyrite (23.8%), pyrrhotite (33.8%), pentlandite (39.0%), and chalcopyrite (1.90%). Furthermore, the nickel distribution reveals that 97.8% of the nickel composites are found in pentlandite, while 2.15% of the nickel composites are present in pyrrhotite. Pentlandite was observed as the primary nickel mineral. Typically, nickel in the form of pentlandite can be effectively recovered using gravity and/or flotation methods.

The current phase of drilling is a continuation of the 2022 drill program in Zones 1 and 2, and will comprise approximately 600 meters in 8 Winkie diamond drill holes. The 2022 Quesnel Nickel program consisted of 42 diamond drill holes, all of which encountered significant nickel, magnesium, chromium, and cobalt concentrations commencing at the surface. The drill holes from 2022 were drilled along two large outcrops known as Zone 1 and Zone 2, which rise approximately 700 feet above the surrounding ground. The deepest hole in 2022 was drilled to a depth of 128 meters and ended in mineralization (See Press Release dated January 5, 2023).

The second stage of this year's drill program (Figure 4) will also include 20 planned NQ diamond drill holes involving a 6,000-meter program to test at depths down to 300 meters and expand on the 14-kilometre strike length around and between Zone 1 and Zone 2. The 2023 program also includes plans for exploration groundwork on its newly expanded Fontaine Gold Project, which will include bedrock mapping, soil and rock sampling, and a geophysical program. Program details will be announced as they are finalized.

Quality Assurance, Quality Control

An AQTK or 35.5 mm (1 3/8 in) diameter core barrel was used for the 2023 diamond drill program at the Quesnel Nickel and Talc Property. The drill stem dip and azimuth was orientated at each collar location by a qualified geologist before drilling. Core samples were generally selected between 0.6 and 1.5-meter intervals, depending on identified lithology and mineralization style. The core was cut in half with a diamond core saw, with half of the core placed in sample bags and the remaining half securely retained in core boxes at Green River's office in Quesnel. The nickel standard samples of high-grade (CDN-ME-2001) and low-grade (CDN-PGMS-29) and the repeat samples which returned from previous assaying and blanks (BL-10) were systematically inserted into each batch of samples at regular intervals and submitted to MSA laboratory. The standard samples were purchased from CDN Resource Laboratories in Langley, British Columbia. The assay lab preparation procedure included crushing the entire sample to 80% passing 2 millimetres, riffle splitting 250 grams, and pulverizing the split to 95% passing 105 micrometres. Base metal analyses are determined using the four-acid digestion method with an ICP-OES finish. Gold analyses are determined using the fire assay method with an ICP-EM finish. Analytical results are verified with the application of industry-standard Quality Assurance and Quality Control (QA/QC) Procedures. The MSA Labs has an ISO 17025 certificate.
