Osisko Metals Incorporated has announced promising new drilling results from its ongoing 2025 exploration program at the Gasp茅 Copper Project, located on the Gasp茅 Peninsula in Eastern Qu茅bec. The latest assays from six new drill holes, situated at the southern end of the deposit outlined in the 2024 Mineral Resource Estimate (MRE), reveal significant copper mineralization and highlight the potential for resource expansion at depth and to the south.
The most notable result comes from drill hole 30-1065, which intersected an impressive 323.0 metres averaging 0.43% copper (Cu) and 3.18 grams per tonne silver (Ag). This broad intersection includes a higher-grade zone of 13.3 metres averaging 2.50% Cu and 17.8 g/t Ag within the C Zone skarn horizon. This hole, drilled near the southern boundary of the current MRE, underscores the continued potential for resource growth in this direction.
Further encouraging results were obtained from drill hole 30-1061, located near the western limit of the 2024 MRE. This hole returned two significant intercepts: 172.5 metres averaging 0.18% Cu and 1.52 g/t Ag, and a deeper intersection of 215.5 metres averaging 0.31% Cu and 2.67 g/t Ag. Importantly, this deeper intercept lies below the current MRE model, extending known mineralization to a vertical depth of 712 metres and suggesting substantial potential for vertical expansion of the deposit.
The current drill program aims to upgrade the Inferred resources from the November 2024 MRE to the Measured and Indicated categories, as well as to explore the potential for expanding the mineralized system at depth and laterally to the south and southwest. The mineralized intersections below the L1 skarn horizon (C Zone) represent potential depth extensions that are slated for inclusion in the next MRE update, anticipated in the first half of 2026.
The mineralization at Gasp茅 is primarily characterized by disseminated and veinlet chalcopyrite, largely controlled by the stratigraphy within the Needle Mountain, Needle East, and Copper Brook areas. While significant molybdenum mineralization was not encountered in the porcellanites in these areas, higher grades of molybdenum were locally observed in both the C Zone and E Zone skarns. The bulk of the molybdenum mineralization is located further north at Copper Mountain, where a distinct porphyry copper-style mineralization forms a secondary zone.
Osisko Metals' drilling efforts between 2022 and 2024 focused on defining open-pit resources within the Copper Mountain stockwork mineralization, culminating in the May 2024 MRE. Subsequent drilling to the south of Copper Mountain, targeting the less explored primary skarn/porcellanite portion of the system, led to a substantial increase in the resource, primarily in the Inferred category, as reported in November 2024. The ongoing 2025 drill program continues to build on these successes, aiming to further delineate and expand the significant copper potential of the Gasp茅 Copper Project.
