Osisko Critical Minerals Upsizes Private Placement to $250 Million

TORONTO, Sept. 21, 2026 /CourierPR/ -- Osisko Critical Minerals Corporation, a wholly-owned subsidiary of Osisko Metals Incorporated, has announced an upsize of its previously announced private placement of special warrants. The company, which was incorporated on September 16, 2026, as detailed in a news release by Osisko Metals, is now seeking to raise up to $250 million, up from the initial target of $100 million. This move reflects strong investor interest and confidence in the company’s exploration portfolio and its strategy in New Brunswick.

The private placement is being led by Canaccord Genuity Corp., acting as lead agent and sole bookrunner, on behalf of a syndicate of agents. All other terms of the private placement remain as described in the prior news release. Legal advisors for Osisko Metals in connection with the private placement are Bennett Jones LLP, while Peterson McVicar LLP is acting as legal advisors to Osisko Critical Minerals Corporation for certain corporate matters. Cassels Brock & Blackwell LLP is advising the agents.

The company's principal assets include the Properties, comprising approximately 645 square kilometres of mineral claims in northern New Brunswick, Canada. The Properties include the NB Copper Project, which hosts large-scale exploration targets for bulk-tonnage copper deposits in a geological setting analogous to the nearby Gaspé Copper Project. Osisko Critical Minerals Corporation is led by John Burzynski as Chief Executive Officer.

The private placement is subject to several conditions, including the completion of legal and tax structuring, financial analysis, negotiation and execution of definitive documentation, and required regulatory approvals. There is no certainty that the private placement will be completed on the terms proposed or at all. Completion is subject to a number of risks and uncertainties, including general market and economic conditions, fluctuations in commodity prices, and the ability to obtain required regulatory approvals.

This upsizing of the private placement underscores the company's ambition and the potential of its exploration projects in New Brunswick. The funds raised will be used to advance the aggressive exploration program on the copper assets and support the broader critical minerals strategy.
