In October 2024, we acquired Osisko Mining, with 100% ownership of the Windfall Project and the extensive surrounding exploration camps in Canada’s Quebec province. Windfall was previously jointly and equally owned by Gold Fields and Osisko. It consists of three key properties: The Windfall project, and the Urban-Barry and Quévillon exploration properties.

We own the Windfall project in Canada’s Quebec province. Windfall is among the largest gold deposits in Canada, and a top 10 gold deposit globally by head grade.
