Osisko Metals Incorporated Announces New Drilling Results from the 2025 Drilling Program at the Gaspé Copper Project, Located in the Gaspé Peninsula of Eastern Québec
Osisko Metals Incorporated announced new drilling results from the 2025 drilling program at the Gaspé Copper Project, located in the Gaspé Peninsula of Eastern Québec. Results for eight new holes are reported below, located at the southern end of the deposit defined in the 2024 Mineral Resource Estimate. Drill hole 30-1075, located in the south-eastern portion of the 2024 MRE model, intersected 258.0 metres averaging 0.33% Cu and 2.95 g/t Ag (including 15.6 metres averaging 1.47% Cu and 8.5 g/t Ag), and a second intercept at depth, below the base of the 2024 MRE model, of 96 metres averaging 0.54% Cu and 3.34 g/t Ag, extending mineralization to a vertical depth of 529 metres. Drill hole 30-1076, located along the southern limit of the 2024 MRE model, intersected 208.4 metres averaging 0.40% Cu and 2.61 g/t Ag (including 12.0 metres averaging 1.91% Cu and 9.6 g/t Ag), followed by a second intercept of 70.8 metres averaging 0.25% Cu and 2.15 g/t Ag, and a third intercept at depth, below the base of the 2024 MRE model, of 48.9 metres averaging 0.34% Cu and 2.78 g/t Ag, extending mineralization to a vertical depth of 548 metres. Drill hole 30-1068, located in the south-eastern portion of the 2024 MRE model, intersected 189.0 metres averaging 0.30% Cu and 2.62 g/t Ag. Drill hole 30-1070, located near the eastern limit of the 2024 MRE model, intersected 160.5 metres averaging 0.16%, Cu and 1.92 g/t Ag, followed by a second intercept of 122.8 metres averaging 0.62% Cu and 4.86 g/t Ag (including 25.6 metres averaging 2.19% Cu and 16.9 g/t Ag at the level of the C Zone skarn), followed by a third intercept at depth, below the base of the 2024 MRE model, of 29.7 metres averaging 1.92% Cu and 15.2 g/t Ag at the level of the E Zone skarn, extending mineralization to a vertical depth of 629 metres. Drill hole 30-1074, located in the south-central portion of the 2024 MRE model, intersected 118.5 metres averaging 0.26% Cu and 1.92 g/t Ag, and a second intercept of 167.2 metres averaging 0.22% Cu and 1.60 g/t Ag at depth below the base of the 2024 MRE model, extending mineralization to a vertical depth of 797 metres. Drill hole 30-1073 was drilled to the east of the 2024 MRE limit and did not intersect significant mineralization. Previously reported drill holes 30-1062 and 30-1066 were also collared to the southeast and to the east, respectively, of the 2024 MRE limit and these holes also failed to intersect significant mineralization, indicating that the deposit does not extend towards the east. The deposit remains open to the south and southwest. All holes were drilled sub-vertically into the altered calcareous stratigraphy which dips 20 to 25 degrees to the north; true widths are estimated at 90-92% of reported widths. The L1 (C Zone) the L2 (E Zone) skarn/marble horizons were intersected in most holes, as well as intervening porcellanites (pale green to white potassic-altered hornfels) that host the bulk of the disseminated copper mineralization. The November 2024 MRE was limited at depth to the base of the L1 skarn horizon (C Zone), and all mineralized intersections below this horizon represent potential depth extensions to the deposit, to be included in the next scheduled MRE update in First Quarter 2026. Mineralization occurs as disseminations and veinlets of chalcopyrite and is mostly stratigraphically controlled in the area of Needle Mountain, Needle East and Copper Brook. As expected, no significant molybdenum mineralization was encountered in porcellanites in the latter areas, but high grades (up to 0.4% Mo) were locally obtained in both the C Zone and E Zone skarns. The bulk of the molybdenum mineralization occurs in veinlet stockworks further north at Copper Mountain, where true porphyry copper-style mineralization occurs, forming a distinct secondary mineralized zone that is characterized by widespread, continuous copper-molybdenum stockwork mineralization radiating from the central source of hydrothermal fluids, i.e. the Copper Mountain porphyry intrusion. At least five vein/stockwork mineralizing events have been recognized at Copper Mountain, which overprint earlier skarn/porcellanite-hosted mineralization throughout the Gaspé Copper system. The 2022 to 2024 Osisko Metals drill programs were focused on defining open-pit resources within the Copper Mountain stockwork mineralization, leading to the May 2024 MRE (see May 6, 2024 press release). Extending the resource model south of Copper Mountain into the poorly-drilled primary skarn/porcellanite portion of the system subsequently led to a significantly increased resource, mostly in the Inferred category. The current drill program is designed to convert the November 2024 MRE to Measured and Indicated categories, as well as test the extension of the system deeper into the stratigraphy and laterally to the south and southwest towards Needle East and Needle Mountain respectively.
