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)

Final environmental approvals and a formal Board Investment Decision (FID) are expected in the second half of 2025 or early 2026.

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.
