Osisko Metals Gaspé Copper Project Intersects 645 Metres Averaging 0.28% Cu

Core Viewpoint - Osisko Metals has announced significant new drilling results from the Gaspé Copper Project, highlighting the potential for resource expansion with the longest continuous intercept to date of 853 meters averaging 0.20% Cu, 1.43 g/t Ag, and 0.02% Mo (0.30% CuEq) [1][2]. Summary by Relevant Sections New Drill Results - Drill hole 30-1082 reported 853.5 meters of continuous mineralization, including a lower intercept of 424.0 meters averaging 0.21% Cu, 1.33 g/t Ag, and 0.026% Mo, extending mineralization to a vertical depth of 1140 meters [11][12]. - Drill hole 30-1089 intersected 645.0 meters averaging 0.28% Cu, 1.46 g/t Ag, and 0.023% Mo, with a lower intercept of 396.7 meters averaging 0.30% Cu, 1.34 g/t Ag, and 0.023% Mo, extending to a depth of 965 meters [15][16]. - Drill hole 30-1083 showed 427.5 meters averaging 0.26% Cu, 1.54 g/t Ag, with a lower intercept of 328.0 meters averaging 0.24% Cu, 1.43 g/t Ag, extending to a depth of 900 meters [12][13]. Mineral Resource Potential - The current drill program aims to convert the November 2024 Mineral Resource Estimate (MRE) to Measured and Indicated categories and test for deeper and lateral expansions [21][22]. - The Gaspé Copper Project hosts Indicated Mineral Resources of 824 million tonnes averaging 0.34% CuEq and Inferred Mineral Resources of 670 million tonnes averaging 0.38% CuEq [30][31]. Geological Context - Mineralization at the Gaspé Copper Project occurs as disseminations and stockworks of chalcopyrite with pyrite or pyrrhotite, with at least five recognized mineralizing events [19]. - The drilling is focused on defining open-pit resources within the Copper Mountain stockwork mineralization, with significant resource increases noted in the Inferred category [20][31].
