    Whitehaven Coal’s 40 Mt output in weak markets: key cost lessons for mine planners

    Whitehaven Coal’s 40 Mt output in weak markets: key cost lessons for mine planners

    First reported on Australian Mining

    30 Second Briefing

    Whitehaven Coal has posted record FY26 managed production of 40.1 million tonnes of saleable coal while coal prices fell 27 per cent and the Australian dollar strengthened 6 per cent against the US dollar. Underlying NPAT came in at $227 million and underlying EBITDA at $702 million, supported by a 9 per cent reduction in unit operating costs to $106 per tonne. For mine planners and operators, the result signals continued high utilisation of existing longwall and open-cut fleets despite weaker thermal and metallurgical coal markets.

    Technical Brief

    • Stronger Australian dollar directly compressed AUD revenue per exported tonne under USD‑denominated coal contracts.
    • For other mining operators, similar FX and price conditions stress‑test longwall availability and strip‑ratio assumptions.

    Our Take

    The FY26 underlying NPAT of A$227 million comes after Whitehaven Coal secured a US$600 million senior secured syndicated facility in April 2026, signalling lenders still see bankable cash flow in its Australian coal portfolio despite softer prices.

    Our database shows multiple 2025–26 items on Whitehaven’s Queensland assets, including a 90%-plus reserve uplift at Blackwater and a A$740 million BUMA Australia contract extension, indicating the company is locking in both longer mine life and contracted mining capacity ahead of any further coal price volatility.

    Ramaco–Indium Brook mine gallium and germanium offtake: key notes for mine planners

    Ramaco Resources has signed a non-binding MOU with Indium Corporation to negotiate supply of gallium and germanium from the Brook mine rare earth and critical-mineral project near Sheridan, Wyoming, described by Ramaco as the nation’s largest unconventional REE and critical-mineral deposit hosted in coal and carbonaceous ore. Brook is the first new US rare earth and critical-mineral mine in over 70 years, with full-scale mining and construction of a pilot processing facility for vertically integrated commercial oxide production already under way. Indium Corporation, a Clinton, New York-based refiner and solder manufacturer supplying the semiconductor and electronics sectors, would channel Brook gallium and germanium into domestic and allied advanced manufacturing supply chains.

    Yancoal record coal output and rising costs: planning signals for mine engineers

    Yancoal has reported record first-half attributable saleable coal production of 19.8Mt, up 5 per cent on 1H 2025’s 18.9Mt, and says the run-rate puts it on track for a new full-year output record across its NSW and Queensland thermal and metallurgical coal operations. Stronger operational performance and higher realised coal prices were partly offset by increased unit costs driven by labour, explosives and overburden removal. For mine planners and contractors, the figures signal sustained high stripping ratios and continued demand for drill-and-blast, haulage and CHPP throughput optimisation into 2027.

    Fortescue’s record 201.3Mt iron ore shipments: project pipeline signals for mine planners

    Record iron ore shipments of 201.3Mt from Fortescue’s Pilbara operations in FY26 drove a nine per cent rise in revenue to $US17 billion, supported by higher earnings and stronger free cash flow. The result comes as Fortescue continues heavy investment in its Western Australian mining hubs, rail network and port capacity to sustain volumes above 200Mtpa. For mine planners and contractors, the numbers signal ongoing demand for large-scale pit development, overburden movement and materials handling upgrades across the Pilbara assets.
