Gold Fields (NYSE: GFI; JSE: GFI) has secured Quebec’s principal environmental approval for its Windfall gold project, clearing the way to restart underground development while it prepares a final investment decision.
The certificate, issued Oct. 30, completes the project’s provincial environmental and social impact review. Gold Fields will now pursue a mining lease and secondary permits, with an updated construction schedule, capital estimate and resource and reserve estimates expected by February alongside its provisional 2026 results, the company said Monday.
“Receiving the Certificate of Authorization for Windfall is a major milestone for Gold Fields and for one of Canada’s highest-grade development-stage gold projects,” CEO Mike Fraser said in a statement. “The Uukiimau Agreement and the Certificate of Authorization demonstrate how responsible mining can be advanced through respect, transparency and shared value creation.”
Windfall is expected to produce about 300,000 oz. of gold annually once ramped up, adding a Canadian operation to the South African producer’s portfolio. The approval removes a key development risk, although updated costs and the construction timetable remain important outstanding items, BMO mining analyst Raj Ray wrote in a note Monday.
Costs and timing
Development capital is expected towards the upper end of Gold Fields’ existing $1.7-billion to $1.9-billion guidance, equivalent to roughly C$2.4 billion to C$2.7 billion and expressed in 2025 U.S. dollars, the company said in August.
BMO models spending of $2.1 billion, about 11% above the upper end of company guidance, and first production in the second half of 2029, Ray wrote.
Underground activities were suspended after the project’s bulk-sample exploration permit expired at the end of August. Gold Fields had been awaiting the separate environmental authorization needed to advance construction.
Personnel and equipment will now be remobilized, with underground work resuming progressively. Early civil works and camp construction covered by existing board authorization will also begin shortly, the company said. The final investment decision remains subject to board approval.
Cree agreement
The environmental authorization follows the June signing of the Uukiimau impact and benefit agreement with the Cree First Nation of Waswanipi, the Cree Nation Government and the Grand Council of the Crees.
The agreement sets out commitments covering training, employment, business opportunities, environmental monitoring and financial participation over the project’s operating life.
Quebec’s Environmental and Social Impact Review Committee, known as COMEX, examined the development, including through public hearings in Lebel-sur-Quévillon and Waswanipi in spring 2026.
Windfall lies on Waswanipi’s traditional territory, about 115 km by road east of Lebel-sur-Quévillon. Windfall Mining Group, a wholly owned Gold Fields subsidiary, is developing the project.
Gold Fields secured full ownership in October 2024 through its C$2.16-billion takeover of Osisko. It had acquired an initial 50% interest in May 2023 for an upfront C$300 million.
Beyond Windfall, Gold Fields controls about 2,500 sq. km in the Urban-Barry and Quévillon areas, where regional exploration is targeting additional discoveries.
