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

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

    First reported on Australian Mining

    30 Second Briefing

    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.

    Technical Brief

    • For other mining operators, similar cost structures reinforce the need for haulage and energy-efficiency optimisation.

    Our Take

    The record 19.8 Mt 1H output follows Yancoal’s acquisition of the Kestrel underground metallurgical coal mine reported in April 2026, suggesting part of the volume uplift is now structurally underpinned by added Bowen Basin capacity rather than just short-term productivity gains.

    Our database shows multiple 2025–26 items on Yancoal maintaining or lifting coal guidance while keeping a cash balance above $2 billion, so higher unit costs in Australia are being absorbed from a relatively strong balance sheet position, giving the operator more room to keep mines running through cost cycles.

    The earlier move to deploy Cat 794 AC electric-drive haul trucks at Mount Thorley Warkworth indicates Yancoal is already spending capex on fleet modernisation, which likely contributes to near-term cost pressure but positions its Australian coal operations for better productivity and decarbonisation metrics over the medium term.

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

    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.

    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.

    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.
