Osisko Intersects 1117.5 Metres Averaging 0.25% Cu at Gaspé

Core Viewpoint - Osisko Metals has reported significant new drilling results from the Gaspé Copper Project, highlighting the longest continuous mineralization intercept to date of 1117.5 meters averaging 0.25% Cu, 1.81 g/t Ag, and 0.022% Mo, which indicates strong potential for resource expansion and upgrade in mineral resource categories [1][2][9]. Summary by Relevant Sections Drilling Results - Drill hole 30-1097 achieved the longest intersection of 1117.5 meters with an average of 0.25% Cu, 1.81 g/t Ag, and 0.022% Mo, including a deeper expansion of 426.0 meters averaging 0.27% Cu [2][9]. - A total of over 65,000 meters of drilling has been completed with 10 drills on site, and the current drilling program will continue until December 2025 [2][4]. Mineral Resource Estimate (MRE) - The updated MRE is expected to be released in Q1 2026, focusing on upgrading inferred mineral resources to measured or indicated categories [2][4][17]. - The current drill program aims to convert the November 2024 MRE to Measured and Indicated categories and test for deeper and lateral expansions [17]. Mineralization Characteristics - The Gaspé Copper mineralization is characterized as porphyry copper/skarn type, with significant occurrences of chalcopyrite, pyrite, and molybdenite [15]. - High molybdenum grades (up to 0.5% Mo) have been noted in specific zones away from Copper Mountain [15]. Company Background - Osisko Metals is focused on the Gaspé Copper Project, which hosts the largest undeveloped copper resource in eastern North America, with current Indicated Mineral Resources of 824 million tonnes averaging 0.34% CuEq and Inferred Mineral Resources of 670 million tonnes averaging 0.38% CuEq [25][26]. - The company acquired a 100% interest in the Gaspé Copper mine from Glencore Canada Corporation in July 2023 [25].
