Drilling at Mount Polley Intersects 11.0 Metres Grading 4.43% Copper, 1.53 g/t Gold and 41.7 g/t Silver

Core Insights - Imperial Metals Corporation has reported the results of the first diamond drill hole from the Mount Polley 2025 Phase 2 Diamond Drill Program, which includes significant mineralization with 11.0 metres grading 4.43% copper, 1.53 g/t gold, and 41.7 g/t silver [1][2]. Drill Program Overview - The Mount Polley 2025 Phase 2 program aims to achieve three objectives: testing a high-grade zone beneath the Wight Pit, expanding and determining the boundaries of higher gold grade mineralization in the C2 zone, and exploring beneath the previously mined Bell Pit using new targeting techniques [2]. - The Phase 2 program consists of nine holes totaling 3,718.3 metres [1]. Drill Hole Details - Drill hole WB-25-268 was targeted at a high-grade area in the Green zone, adjacent to the Martel zone, beneath the Wight Pit [5]. - The hole intercepted a hydrothermal fragmental potassic-altered breccia with significant mineralization, including additional higher-grade sections above and below the targeted area [8]. - The detailed results from hole WB-25-268 include: - 1.5 metres grading 3.58% copper, 0.07 g/t gold, and 13.6 g/t silver from 254.6 to 256.1 metres - 9.6 metres grading 3.71% copper, 0.42 g/t gold, and 9.89 g/t silver from 272.5 to 282.1 metres - 11.0 metres grading 4.43% copper, 1.53 g/t gold, and 41.7 g/t silver from 304.4 to 315.4 metres [9]. Mineralization Characteristics - The higher silver to copper ratio observed in this hole is typical for the northeast quadrant of the Mount Polley property, indicating potential for further exploration in this area in 2026 [10]. - The Martel zone has been previously defined as an underground resource, with an indicated resource of 2,272,000 tonnes grading 1.14% copper, 0.30 g/t gold, and 7.20 g/t silver as of January 1, 2025 [11]. Company Profile - Imperial Metals is based in Vancouver and is involved in exploration, mine development, and operations, holding the Mount Polley mine (100%), Huckleberry mine (100%), and Red Chris mine (30%), along with a portfolio of 23 exploration properties in British Columbia [12].
