Osisko Critical Minerals Corporation Announces C$100 Million Private Placement of Special Warrants

Osisko Critical Minerals Corporation (OCMC), a wholly-owned subsidiary of Osisko Metals Incorporated (OM), announced a best-efforts private placement of special warrants to raise gross proceeds of C$100 million. Canaccord Genuity is acting as the lead agent and sole bookrunner for the offering. The warrants are priced at $0.25 per unit, with proceeds allocated to the exploration and development of OCMC's New Brunswick properties, including the NB Copper Project and Bathurst Mining Camp holdings, as well as general working capital.

Each special warrant converts into one common share plus one-half of a common share purchase warrant exercisable at $0.35 per share for a 24-month period. Closing is expected on or about November 17, 2026, contingent on prospectus qualification and TSX Venture Exchange listing approval. This announcement follows the September 15, 2026 spin-out of the New Brunswick assets into OCMC.

Osisko Metals Incorporated has executed a financing step consistent with its previously announced spin-out strategy, providing dedicated capital to advance its New Brunswick portfolio independently from the parent company. This incremental funding follows directly from the September 15 corporate restructuring announcement, a move the market has already priced in alongside the associated capital raise.

The transaction will be dilutive to Osisko Metals upon conversion, though the capital remains within the subsidiary to accelerate exploration and de-risk the assets. The news confirms management's commitment to advancing the NB assets but introduces no new strategic investors, unexpected valuation changes, or material shifts in the parent company's operational trajectory. It does not alter the fundamental thesis or near-term catalysts for Osisko Metals.

Osisko Metals Incorporated (OM) is a Canadian copper development company focused on the Gaspé Copper Project in Eastern Québec. The flagship Gaspé Copper Project is a brownfield site with extensive infrastructure, including highway access, port proximity, and power substation. The 2026 Mineral Resource Estimate reports 1.83 billion tonnes of Measured and Indicated resources at 0.32% CuEq, containing 10.77 billion pounds of copper.

The company also holds the Pine Point Project in the Northwest Territories via a joint venture with Appian Capital Advisory. Additionally, the newly formed OCMC holds approximately 645 square kilometres of critical mineral exploration properties in northern New Brunswick, including the NB Copper Project and historic zinc-lead assets in the Bathurst Mining Camp.
