Osisko Metals Intersects 731 Metres Averaging 0.29% Cu at Gaspé

Core Viewpoint - Osisko Metals has announced promising new drill results from the Gaspé Copper Project, indicating significant resource expansion potential and the possibility of increasing the mineral resource estimate (MRE) in the upcoming update scheduled for Q1 2026 [1][2][19]. Summary by Relevant Sections Drill Results - New analytical results include 20 mineralized intercepts from 7 new drill holes, with infill intercepts aimed at upgrading inferred mineral resources and expansion intercepts potentially leading to additional resources [3][5]. - Drill hole 30-0872 returned 92.1 metres averaging 0.24% Cu and 3.05 g/t Ag, followed by a higher grade intercept of 47.2 metres averaging 1.14% Cu and 11.8 g/t Ag, extending mineralization to a vertical depth of 390 metres [9][10]. - Drill hole 30-1085 intersected 219.0 metres averaging 0.41% Cu and 2.79 g/t Ag, and a second intercept of 754.5 metres averaging 0.24% Cu, extending mineralization to a vertical depth of 1110 metres [10][12]. - Drill hole 30-1092 returned 331.5 metres averaging 0.37% Cu and 3.21 g/t Ag, located 230 metres south of the 2024 MRE model [11]. - Drill hole 30-1096 intersected 730.7 metres averaging 0.29% Cu, extending mineralization to a vertical depth of 1062 metres [13]. - Drill hole 30-1099 showed 614.7 metres averaging 0.23% Cu, extending mineralization in the porphyry core of the deposit to a vertical depth of 1000 metres [15]. Resource Expansion Plans - The current drill program aims to convert the November 2024 MRE to Measured and Indicated categories and test the expansion of the system deeper and laterally [19]. - Additional drill holes are planned in the resource expansion target area, covering a surface of 450 metres by 550 metres, which is expected to add significant new tonnage to the MRE update [2][19]. 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 [29][30].
