The project is currently in the , with Gold Fields aiming for aggressive development timelines:
The feasibility study projected an All-In Sustaining Cost ( AISC ) of approximately US$758–$760 per ounce , positioning it as one of the lowest-cost mines in Canada.
The site is now fully powered by hydroelectricity through an 85km power line operated by the Cree First Nation of Waswanipi , significantly reducing the project's carbon footprint.
Once at steady state, the mine is projected to produce 300,000 ounces of gold annually . Key Metrics & Infrastructure
As of April 2026, the has transitioned from an exploration-focused play to a high-priority development asset under the full ownership of Gold Fields , which completed a $2.1 billion acquisition of Osisko Mining in October 2024. While the project is moving toward construction, drilling continues to yield the "bonanza" grades that made the deposit famous. Latest Drilling & Exploration Highlights (Early 2026)
