Osisko Intersects 592 Metres Averaging 0.33% Cu at Gaspe
None
On October 29, 2025, Osisko Metals announced new drilling results from its ongoing program at the Gaspé Copper Project in Québec. The results are from nine holes totaling 10,227.7 metres.
Key intercepts include: - Hole 30-1107: 592.0 metres averaging 0.33% Copper (Cu), 1.68 g/t Silver (Ag), and 0.032% Molybdenum (Mo). - Hole 30-1112: 868.5 metres averaging 0.23% Cu, 1.45 g/t Ag, and 0.019% Mo. - Hole 30-1122: 760.5 metres averaging 0.24% Cu, 1.71 g/t Ag, and 0.015% Mo. - Hole 30-1119: 46.4 metres averaging 1.10% Cu and 5.08 g/t Ag. - Hole 30-1114: 142.1 metres averaging 0.39% Cu and 1.5 g/t Ag.
CEO Robert Wares stated that the results continue to confirm and expand the resource model, deepening the deposit and confirming its southern extension. He also noted the favorable macro environment with copper approaching US$5/lb.
The news is positive as it demonstrates continued drilling success, reinforcing the geological model and the large-scale nature of the Gaspé Copper deposit. The results are consistent with, and in some cases exceed, the average grade of the current mineral resource estimate (MRE). The long intercepts confirm the bulk-tonnage potential that the company is targeting.
However, the impact is rated as Routine - Positive. Over the past year, Osisko Metals has consistently released similar results from its extensive 110,000-metre drill program. The market has come to expect these long, continuous intercepts that confirm and expand the resource. This release, while strong, does not fundamentally change the investment thesis established by the transformative November 2024 MRE and the subsequent C$107.4M financing. It represents solid, ongoing execution of a well-defined plan.
The results successfully de-risk the project by improving confidence in the resource ahead of the planned MRE update in Q1 2026. The continued expansion at depth and to the south is exactly what the drill program was designed to achieve. While not a game-changer on its own, this news is an important and expected step in advancing Gaspé Copper.
Osisko Metals Incorporated is a Canadian exploration and development company focused on critical metals, primarily copper and zinc.
Its flagship asset is the Gaspé Copper Project, located in Québec. This is a past-producing mine acquired from Glencore in 2023. Osisko Metals is redefining the project as a large-scale, open-pit, bulk-tonnage copper-molybdenum deposit. The November 2024 MRE established it as the largest undeveloped copper resource in Eastern North America, with an Indicated Resource of 824 million tonnes at 0.34% CuEq and an Inferred Resource of 670 million tonnes at 0.38% CuEq. The company is in the midst of a 110,000-metre drill program to upgrade and expand this resource.
The company also holds a significant interest in the Pine Point Project, a past-producing zinc-lead mining camp in the Northwest Territories, which is being advanced toward a feasibility study via a joint venture with Appian Capital Advisory LLP.
