Core Insights - Stuhini Exploration Ltd. reported highly favorable metallurgical test results from a surface mini-bulk sample at the Silver Surprise Zone, confirming a 95% silver recovery from a sample with a grade of 4,200 g/t silver [1][2][4] Metallurgical Results - The 1585 lb (719 kg) mini-bulk sample confirmed very high-grade silver mineralization with a recovery of 95% silver via direct smelting, and a gravity separation process recovered 15% of the contained silver [6][9] - The gravity separation produced a refined silver bar weighing 445 grams (14.3 troy ounces) [8] - Tailings after gravity separation assayed 3,540 g/t silver, indicating a significant amount of free and heavy silver [6][9] Strategic Importance - The results are significant as they confirm the potential for a low-complexity processing route for the ultra-high-grade, quartz-hosted silver mineralization, which is well-suited for direct smelting [4][9] - The high recovery rates align with the rising global demand for silver driven by investment interest and industrial applications [2] Future Plans - The Silver Surprise Zone remains open for further exploration, with plans for follow-up prospecting and sampling in 2026, as well as the possibility of a larger bulk sample or drilling program [10][12] Project Overview - The Ruby Creek Project spans 29,734 hectares and includes the highest silver grades identified on the property, with previous surface grab sampling showing values between 1,000 g/t and 16,030 g/t silver [11][16] - The project also hosts a molybdenum deposit with a measured and indicated resource of 433 million pounds [16][17]
