VANCOUVER, British Columbia, Jan. 26, 2026 (GLOBE NEWSWIRE) -- Orezone Gold Corporation (TSX: ORE| ASX: ORE | OTCQX: ORZCF) (“Orezone” or “Company”) is pleased to announce that it has entered into a definitive agreement (the “Agreement”) to acquire (the “Transaction”) Hecla Quebec Inc. (“Hecla Quebec”), a wholly owned subsidiary of Hecla Mining Company (“Hecla Mining”). Through this Transaction, Orezone will acquire 100% ownership of the operating Casa Berardi gold mine and a portfolio of exploration properties, all located in Quebec. Consideration for the acquisition consists of upfront and deferred consideration of $352M (the “Upfront and Deferred Consideration”) and contingent consideration of up to $241M (the “Contingent Consideration”) (the “Transaction”).

The Upfront and Deferred Consideration consists of $160M in cash and $112M in Orezone common shares representing 9.9% of the pro forma issued and outstanding shares of Orezone, both payable upon closing of the Transaction, and $80M of deferred consideration in two cash installments payable at 18 months and 30 months following the closing of the Transaction. The Contingent Consideration consists of $10M linked to gold prices, and $231M based on permitting and future gold production from the proposed Principal and WMCP open pits of Casa Berardi.

This Transaction marks a significant inflection point for Orezone as it adds a proven, cash-flow-generating asset to our portfolio, and provides asset diversification in a Tier 1 Jurisdiction,” commented Patrick Downey, President & CEO of Orezone. “The combination of Casa Berardi and Bomboré creates a multi-asset platform with strong production and free cash flow, positioning Orezone for near-term growth and long-term value creation. Casa Berardi’s established operating history, robust resource and reserve base, and substantial exploration upside across a 37 km mineralized corridor, provide a foundation for sustained growth. Consistent with recent acquisitions of non-core Canadian operating mines, we believe this transaction represents a defining milestone that will generate meaningful value for all shareholders.

I want to thank Franco-Nevada for their sponsorship in this acquisition, and their team’s dedication and support throughout. We welcome Hecla Mining as a new major shareholder and are committed to maintaining and building upon their legacy in the region. In addition, we welcome all of Hecla Quebec’s employees to the Orezone team, and are excited to continue to advance the long-term success of the Casa Berardi mine for the benefit of all project stakeholders, including local communities and Abitibiwinni First Nation.”

“We are delighted to partner with Orezone in this transformative transaction to acquire the Casa Berardi mine and portfolio of exploration properties in Quebec,” said Paul Brink, President & CEO of Franco-Nevada Corporation. “Patrick and the Orezone team have an excellent track record operating and developing mines and we look forward to their future success as they advance Casa Berardi’s next chapter.”
