Set to become Canada's next major mining complex, the Windfall Project is located in the Eeyou Istchee James Bay territory in Québec, 115 km east of Lebel-sur-Quévillon.

Second Series of Responses to COMEX and Update of Key Studies for the Advancement of the Windfall ProjectWMG confirms the continuation of the environmental assessment process through the submission of the second series of responses to COMEX questions. This revision reflects the company's ESG performance standards, adapted to Canadian and Quebec regulatory requirements.

"WMG remains committed to developing a low-carbon operation, including through its partnership with the Cree First Nation, positioning Windfall among the lowest carbon-intensity gold projects globally", said Mike Fraser, CEO of Gold Fields.

"The update of our environmental impact assessment study with the submission of this second series of responses to COMEX demonstrates our commitment to advancing the Windfall project in accordance with the best practice environmental, social, and regulatory standards." added Andréanne Boisvert, Vice President, Environment and Community Relations. 

Visual Identity: The Lynx Gives Way to the LionFollowing the full acquisition of the Windfall project in 2024, WMG is adopting the corporate group's visual identity. The company's transitional logo is being replaced by that of Gold Fields, marking the integration of the project into the global Gold Fields family, which operates across four continents.
