Stuhini completes mini-bulk sample at Ruby Creek

Ms. Meredith Eades reports STUHINI COMPLETES MINI BULK SAMPLE AT RUBY CREEK'S SILVER SURPRISE ZONE Stuhini Exploration Ltd. has extracted a 1,585-pound mini-bulk sample from the Silver Surprise zone at its 100-per-cent-owned Ruby Creek project, near Atlin, B.C. Extraction of the mini-bulk sample was completed at surface with hand tools along one of the Silver Surprise zone veins by a two-person team over a two-day period. The objective of this mini-bulk sample is to test and advance metallurgical understanding of the high-grade silver mineralization identified during prior Ruby Creek project exploration programs (see press release dated April 6, 2021, and Feb. 22, 2022). Analysis of the refined silver from this preliminary test will determine the likelihood of completing larger bulk samples in 2026. A bulk sample is a large, representative quantity of material extracted for detailed testing to determine its composition, properties and commercial potential. "With growing interest in silver globally, both from investors and the broader commodity markets, Silver Surprise zone stands out as one of the most compelling silver zones on the property," said Meredith Eades, president and chief executive officer. "With multiple samples over 10,000 grams per tonne silver and room to grow, we're excited to be advancing metallurgical work and further define the mineralized trend. This is an important step toward unlocking the full silver potential at Ruby Creek." Silver surprise zone highlights: Located along strike of the broader Adera structural corridor; Contains the highest-grade silver samples encountered on the Ruby Creek project to date, placing it firmly in bonanza-grade category; 28 samples between 1,000 and 16,030 grams per tonne silver and four samples over 10,000 g/t Ag, including: 16,030 g/t Ag; 14,179 g/t Ag; 12,980 g/t Ag; Mineralization hosted in massive sulphide-bearing quartz veins; Three parallel veins to date approximately one metre in width up to 180 m in length at surface; Remains open along strike and at depth. Mineralization at Silver Surprise zone occurs in at least three quartz-sulphide veins and vein breccias that are each approximately one m wide within the main body of the Surprise Lake batholith. The veins are exposed semi-continuously for a length from 180 m, 50 m and 30 m, respectively, before they are submerged beneath the talus. The veins are clustered within 200m laterally striking approximately 220 degrees and align with the Adera structural corridor and are subvertical. They appear to remain open at depth as well as along strike in both directions. There are also anomalous float samples uphill from the current occurrences on the talus slope. Petrography has shown the silver mineralization to occur predominantly as silver-tin sulphides (canfieldite) as well as acanthite and rare native silver with galena and pyrite plus or minus sphalerite and arsenopyrite. This mini-bulk sample will be processed, analyzed and monitored in Atlin under the direction of Rino Mihoc, a seasoned metallurgist with over 20 years of hands-on experience. For this program, Mr. Mihoc will oversee the metallurgical test design, with a focus on gravity separation and advanced mineralogical analysis. Results from the program will help inform future drill targeting, mineralogical modelling and development planning. Further geological mapping and geochemical sampling are under way to test potential extensions along the mineralized trend. Maps and imagery showing the sample site and structural features will be released as data become available. Historically, the Atlin region is known for the past-producing Atlin Ruffner silver mine, located 23 road kilometres from Atlin and approximately 12 km west of the Silver Surprise zone. It is reported that, around 1951, this mine produced a shipment of 44 tons of ore grossing seven ounces gold, 5,343 ounces silver, 36,197 pounds lead and 5,824 pounds of zinc.

About the Ruby Creek project The 29,734-hectare Ruby Creek project is road accessible and located 14 km east of Atlin, B.C. There are 48 different documented mineral occurrences on the property, of which 16 are gold related, with seven significant gold placer creeks. The property also hosts the Ruby Creek molybdenum deposit, which hosts a measured and indicated pit-constrained resource of 433 million pounds molybdenum using a molybdenum price of $15 (U.S.) per pound and a 0.02-per-cent cut-off grade (see news release dated March 15, 2022). Stuhini owns 100 per cent of the Ruby Creek project. About Stuhini Exploration Ltd.
