    Gold Fields' Windfall Expansion: Key Takeaways for Mining Professionals

    November 17, 2025
    Gold Fields' Windfall Expansion: Key Takeaways for Mining Professionals

    First reported on MINING.com(Gold Fields doubles down on growth with expanded Windfall project)

    30 Second Briefing

    Gold Fields has significantly increased its investment in the Windfall gold project in Quebec, revising capital expenditure to C$1.7-C$1.9 billion from an initial C$790 million. The project is expected to produce an average of 306,000 ounces of gold annually, with an impressive Internal Rate of Return of 34% and All-in Sustaining Cost of $758 per ounce. Construction is set to begin in Q2 2025, with first production anticipated by late 2026, while a crucial impact-benefit agreement with local First Nations remains pending.

    Technical Brief

    • Gold Fields has increased its capital expenditure for the Windfall project to C$1.7-C$1.9 billion, up from C$790 million, indicating a more comprehensive development plan.
    • The project aims to produce an average of 306,000 ounces of gold annually, with an Internal Rate of Return of 34% and an All-in Sustaining Cost of $758 per ounce.
    • Gold Fields projects an after-tax Net Present Value of C$1.2 billion for the Windfall project.
    • The company plans to increase its annual gold output to 3 million ounces by 2030, stabilising between 2.5 and 3 million ounces annually from 2031-2035.
    • Gold Fields has committed to returning C$500 million to shareholders over the next two years through dividends or share buybacks.

    Context From Recent Coverage

    • With an after-tax NPV of $1.2 billion and a 34% IRR at an AISC of $758/oz, Windfall positions Gold Fields competitively against other Canadian gold projects flagged in the federal Major Projects process, which often rely on higher-cost or polymetallic profiles to clear investment hurdles.
    • The 85 km, 69 kV First Nations-owned hydro-electric power line in Quebec aligns with Canada’s push to fast-track lower-carbon, grid-connected mines, contrasting with several other gold-linked projects in the database that still depend on diesel or mixed power solutions.

    Liontown’s online lithium auction: implications for contract strategy and pricing for mine planners

    Liontown Resources’ inaugural online auction for spodumene concentrate from the Kathleen Valley project drew over 50 qualified buyers spanning nine countries, signalling a shift from traditional offtake contracts to digital spot sales. The auction platform enabled real-time competitive bidding for lithium units, reflecting growing global demand and price volatility. This approach could alter contract negotiation dynamics for Australian lithium producers as spot market mechanisms gain traction.

    Andy Well gold drilling: implications for near-surface resource expansion and mine planning

    Meeka Metals has intersected shallow, high-grade gold mineralisation at its Andy Well underground mine, extending the Wilber lode strike. Drilling revealed significant gold grades at relatively shallow depths, indicating potential for near-surface resource expansion. These results could enhance future mine planning by enabling access to additional high-grade ore zones without deep development.
