The nine hole Phase 2 program consisted of 3,718.3 metres. The Mount Polley 2025 Phase 2 program had three goals; to test a high-grade zone beneath the Wight Pit (See Figure 1), to expand and determine the boundaries for mineralization in the higher gold grade encountered at depth in the C2 zone, and to test beneath the previously mined Bell Pit for depth extension using new targeting techniques successfully deployed in the Springer Pit. The results of the first hole drilled in this program have been received, with the remainder pending. Figure 1: Wight Pit Drill Plan Drill hole WB-25-268 was collared on the eastern edge of the previously mined Wight Pit and targeted a high-grade area located in the Green zone, adjacent to the Martel zone, at depth beneath the Wight Pit (See Figure 2). The goal of drill hole WB-25-268 was to test the continuity and further define the high-grade zone originally defined by holes WB-05-189 (15.0 metres grading 3.1% copper, 0.33 g/t gold, and 20.1 g/t silver) and WB-04-179 (12.4 metres grading 6.7% copper, 3.65 g/t gold, and 44.8 g/t silver). Figure 2: Wight Pit Drill Cross Section Hole WB-25-268 intercepted a hydrothermal fragmental potassic-altered breccia hosting significant bornite and chalcopyrite cement at the target depth that returned from 304.4 metres, 11.0 metres grading 4.43% copper, 1.53 g/t gold and 41.7 g/t silver. In addition to the mineralization intercepted in the targeted zone the hole intersected a number of other higher-grade sections, both above and below the targeted area, including 9.6 metres grading 3.71% copper, 0.42 g/t gold and 9.89 g/t silver starting at 272.5 metres.
