Gold Fields clears Windfall environmental hurdle
Gold Fields (GFI) received Quebec's environmental approval for its Windfall gold project, allowing it to resume underground development. The company expects to provide updated capital estimates and a construction schedule by February. Windfall is projected to produce 300,000 oz. of gold annually, with development costs estimated between $1.7B and $1.9B. BMO analyst Raj Ray anticipates higher costs and first production in late 2029. The project is subject to further permits and board approval.
