Sirios Resources Combines with OVI Mining, Advancing Cheechoo Gold Project in Québec's James Bay Region

Sirios Resources is a Québec-based gold exploration and development company focused on the Eeyou Istchee James Bay region. Its flagship Cheechoo gold project is one of the largest in the province by resource size and benefits from favorable geology, near-surface mineralization, and existing infrastructure. The company completed a transformational combination with OVI Mining in December 2025, integrating Sirios into the Osisko development ecosystem and strengthening the leadership team. With over 30 years of exploration experience in James Bay and strong partnerships with local and Indigenous communities, Sirios is well-positioned to create value through disciplined project advancement and exploration-driven growth.
