Osisko Intersects 330.6 Metres Averaging 0.46% Cu in Southern Extension at Gaspe
None
On November 12, 2025, Osisko Metals announced new drill results from its Gaspé Copper Project in Québec. The results are from 10 holes totaling 9,729.2 metres as part of the ongoing definition and expansion drill program. The headline intercept was from hole 30-1128 in the southern extension of the deposit, which returned 330.6 metres averaging 0.46% Copper (Cu). Other significant results included hole 30-1115, which intersected two separate high-grade expansion zones of 33.0 metres at 1.28% Cu and 56.1 metres at 0.59% Cu. The release also featured several other long intercepts, such as 779 metres of 0.26% Cu and 804 metres of 0.24% Cu. The drilling continues to test for infill and expansion mineralization.
The drill results announced on November 12, 2025, are materially positive and align with the successful trend of results released throughout the year. The headline intercept of 330.6 metres at 0.46% Cu is strong, and the higher-grade intercept of 33.0 metres at 1.28% Cu is a significant bonus. These results successfully demonstrate continued expansion of the mineralized footprint, particularly in the southern extension, which has been a key objective of the 2025 drill program.
Looking at the progression of news, the company has consistently delivered on its exploration plan since the transformative C$107.4 million financing and management overhaul in December 2024. A timeline of key drill results highlights this consistency: - April 14: 300 m @ 0.39% Cu - May 5: 323 m @ 0.43% Cu - July 10: 279 m @ 0.49% Cu - August 13: 731 m @ 0.29% Cu - September 4: 1117.5 m @ 0.25% Cu - September 18: 133.7 m @ 1.04% Cu - October 29: 592 m @ 0.33% Cu - November 12: 330.6 m @ 0.46% Cu
The latest results are not a "game-changer" in isolation, as the market has come to expect strong results from this large-scale drill program. However, they are a crucial confirmation that the geological model holds up and that the deposit continues to grow. Each successful expansion hole adds tonnage and de-risks the project ahead of the planned Mineral Resource Estimate (MRE) update in Q1 2026. This consistent execution is what underpins the stock's significant re-rating in 2025. The results are in line with expectations, reinforcing the project's potential as one of North America's largest undeveloped copper resources.
Osisko Metals is a Canadian exploration and development company focused on critical metals. Its flagship asset is the 100%-owned Gaspé Copper Project, a past-producing mine located in the Gaspé Peninsula, Québec. Acquired from Glencore in July 2023, it is now considered the largest undeveloped copper resource in Eastern North America. The current focus is a large-scale 110,000-metre drill program designed to upgrade and expand the substantial NI 43-101 resource estimate published in November 2024 (824 Mt @ 0.34% CuEq Indicated and 670 Mt @ 0.38% CuEq Inferred). The company also holds an interest in the Pine Point zinc project in the Northwest Territories through a joint venture.
