GREEN RIVER GOLD PROVIDES DRILLING UPDATE AND REPORTS ASSAY RESULTS FROM THE ALTERATION ZONE OF DRILL HOLE WK-23-01, INCLUDING 7583 GRAMS PER TONNE ZINC, 4340 GRAMS PER TONNE LEAD, 5.3 GRAMS PER TONNE SILVER, AND 0.158 GRAMS PER TONNE GOLD

Green River Gold Corp. has released assay results from the alteration zone from drill hole WK-23-01 and preliminary X-ray fluorescence (XRF) scanning results of drill hole WK-23-02. The drilling results are from the company's 100-per-cent-owned Quesnel nickel project, located 40 kilometres east by road from Quesnel, B.C., in the prolific Cariboo mining district in south-central British Columbia, Canada.

Drill hole WK-23-01 was drilled approximately 900 metres southeast of zone 1, between zone 1 and zone 2. A strong serpentinized alteration zone was intersected in this hole from 47.4 metres to 50.8 metres. The assay results returned from the MSA lab in Langley, B.C., indicate the central part of the altered section (from 48.3 metres to 48.9 metres) contains 7,583 grams per tonne zinc, 4,350 grams per tonne lead, 5.3 grams per tonne silver and 0.158 gram per tonne gold. The assay results in this polymetallic vein confirm the presence of high0grade silver, lead and zinc, and elevated values of gold and copper. The assay results for the rest of the drill core from hole WK-23-01 are expected to be received from the MSA lab within the next two weeks.

Project geologist Tyler Tian comments on the assaying results: "The silver, lead, zinc and copper anomaly in the first hole drilled this year indicates the semi-massive sulphides are made up of pyrite, chalcopyrite, sphalerite and galena. It is exciting to see that the polymetallic vein intersects the ultramafic body and is associated with gold. More drill holes are planned for the area surrounding hole WK-23-01 in attempt to intersect the polymetallic vein system again."

Kyle Townsend, mine manager for Green River, says: "I was thrilled to learn that our latest drilling has encountered semi-massive sulphides containing lead, zinc, silver, copper and gold. These assay results confirm our belief that this area has significant potential for mineralization, and we are excited to continue exploring this site for further discoveries. This is a major step in our journey towards becoming a leading player in the mining industry, and we are eager to share this news with our shareholders and stakeholders."

As reported earlier (see press release of May 15, 2023), drill hole WK-23-01 was drilled to a depth of 120.9 metres to test the continuity of the known occurrence of nickel, cobalt, chromium and magnesium along the Deep Purple magnetic anomaly. The drill core was delivered to the company's facility in Quesnel and was scanned with an XRF analyzer. From the surface to 120.9 metres, the XRF scanned every 10 centimetres along the drill core and results averaged 0.194 per cent nickel, 0.0157 per cent cobalt, 0.195 per cent chromium and 22.47 per cent magnesium. The XRF results for all four minerals are quite consistent with the assay and XRF results from the previous 42 holes drilled across the magnetic anomaly.

Drill hole WK-23-02 was also drilled using a Winkie drill to establish the continuity of the mineralization farther along the Deep Purple magnetic anomaly. The company completed this second drill hole (WK-23-02) for the 2023 season, which ended at 98.6 metres. The primary host rock in both holes (WK-23-01 and 02) is an ultramafic rock (peridotite) belonging to the Slide Mountain terrane (crooked amphibolite). The drill core was delivered to the company's facility in Quesnel and was scanned with an XRF analyzer. From surface to 98.6 metres, the XRF scanned every 10 cm along the drill core and the analytical results averaged 0.233 per cent nickel, 0.0179 per cent cobalt, 0.226 per cent chromium and 23.73 per cent magnesium. The XRF results for all four commodities in holes WK-23-01 and 02 are consistent with the assay and XRF results from the previous 43 holes drilled along the magnetic anomaly.

Note: The XRF data are taken as point values and will not represent the true grade of the samples analyzed. The elemental data are highly dependent on the location of which the beam intersects the rock. The device used to take the data points is a 2023 SciAps X-550 hand-held X-ray fluorescence (XRF) analyzer, which produces a beam spot diameter up to three millimetres. It is designed to achieve laboratory-quality results in the field and provides rapid and accurate elemental analysis and testing.

The next phase of drilling will be a continuation of the 2022 drill program in zones 1 and 2 and will comprise approximately 500 metres in five 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 commencing at the surface. The drill holes from 2022 were drilled from 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 metres and ended in mineralization (see press release dated Jan. 5, 2023).

The next drill hole WK-23-03 is presently being drilled 90 metres southeast of WK-23-01. This hole has dual purpose; the company hopes to continue to establish the continuity of the nickel occurrence along the Deep Purple magnetic anomaly, while also attempting to connect with the potential extension of the semi-massive sulphides in the polymetallic vein intersected in drill hole WK-23-01.

The second stage of this year's program will also include 20 planned NQ diamond drill holes involving a 6,000-metre program to test at depths down to 300 metres and expand on the 14-kilometre strike 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 (1-3/8ths inches) diameter core barrel was used for the 2023 diamond drill program at the Quesnel nickel and talc property. The drill stem dip and azimuth were orientated at each collar location by a qualified geologist prior to drilling. Core samples were generally selected between 0.6 and 1.5 m 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. Standard samples and the repeat samples which returned from previous assaying and blanks (CDN-BL-10) were systematically inserted into each batch of samples at regular intervals. The standard samples include high-grade (CDN-ME-2001) and low-grade (CDN-PGMS-29) nickel samples purchased from CDN Resource Laboratories in Langley, B.C. The core samples placed in sealed bags were shipped directly to Met-Solve Laboratories Inc. (MSA) in Langley, B.C. The assaying lab preparation procedure included crushing the entire sample to 80 per cent passing two millimetres, riffle splitting 250 grams and pulverizing the split to 95 per cent passing 105 micrometres. Base metal analyses are determined using the four-acid digestion method with an inductively coupled plasma optical emission spectroscopy finish. Gold analyses are determined using the fire assaying method with an ICP-EM finish. Analytical results are verified with the application of industry-standard quality assurance and quality control (QA/QC) procedures. MSA Labs has an ISO 17025 certificate.
