SIRIOS AND OVI COMBINE TO FORM AN OSISKO-BACKED GOLD COMPANY IN EEYOU ISTCHEE JAMES BAY
Sirios Gets Osisko's Midas Touch in James Bay Consolidation Play
On December 11, 2025, Sirios Resources Inc. announced a definitive agreement to acquire OVI Mining Corp. ("OVI") in an all-share transaction. Under the terms of the deal, each OVI share will be exchanged for 2.34 Sirios shares. Upon completion, existing Sirios shareholders will own approximately 75% of the combined company, with former OVI shareholders holding the remaining 25%.
The transaction will result in a significant management and board overhaul. Jean-Félix Lepage, CEO of OVI, will become the new CEO of the combined company. Sean Roosen, CEO of Osisko Development, and Laurence Farmer will join the Board of Directors. Sirios' founder, Dominique Doucet, will remain with the company to provide his extensive geological expertise. The stated rationale for the combination is to create a well-capitalized, Osisko-backed gold company focused on advancing Sirios' flagship Cheechoo gold project in Quebec's Eeyou Istchee James Bay region.
This transaction is a pivotal and transformative event for Sirios. While the company has successfully defined a significant gold resource at its Cheechoo project, it has historically lacked the market visibility and development-focused management required to advance the asset. This merger directly addresses these critical shortcomings.
The involvement of Sean Roosen and the "Osisko-backed" branding is the most significant aspect of this deal. The Osisko group has a stellar track record of developing and financing major gold mines in Quebec, most notably Canadian Malartic. This association provides Sirios with unparalleled credibility in the capital markets, improves access to financing, and brings proven mine-building expertise to the table. The market typically assigns a significant premium to companies with Osisko's endorsement.
The management transition is also a logical and necessary step. Dominique Doucet, a geologist by trade, has successfully guided the company through its discovery and resource definition phases. The appointment of Jean-Félix Lepage, who has a corporate finance background, signals a clear shift in strategy towards project development and commercialization. Retaining Mr. Doucet ensures continuity of the deep technical knowledge of the asset.
Critically, Sirios is effectively using its well-defined asset to attract a top-tier management and development team. While the 25% dilution to existing shareholders for what appears to be primarily a management team and strategic relationship may seem steep, it is a strategic trade-off. In the current market, the value added by a proven team with access to capital far outweighs the dilution, as it dramatically increases the probability of the Cheechoo project being advanced towards production.
Tracing the company's progress, Sirios spent late 2024 and early 2025 delivering excellent drill results that validated a new geological model for Cheechoo. This culminated in a significant Mineral Resource Estimate (MRE) update in July 2025, which increased both ounces and grade. The company subsequently completed a $2.5 million financing and began infrastructure upgrades. The merger with OVI is the logical and perhaps essential next step to capitalize on these technical successes. The transaction transforms Sirios from a technically sound explorer into a credible development company.
Sirios Resources Inc. is a Canadian junior exploration company focused on gold properties in Quebec. Its flagship asset is the 100%-owned Cheechoo gold project, located in the Eeyou Istchee James Bay region. The project is situated adjacent to the Éléonore gold mine, which was acquired by Dhilmar Ltd. from Newmont in 2024. As of July 2025, the Cheechoo project hosts an NI 43-101 compliant Mineral Resource Estimate of 1.3 million ounces of gold in the Indicated category at a grade of 1.12 g/t Au and 1.7 million ounces of gold in the Inferred category at 1.23 g/t Au, with potential for both open-pit and underground mining scenarios. The company also holds the Aquilon project in a joint venture with Sumitomo Metal Mining Canada.
