Key Highlights

  • BHP's coal Business delivered higher realised steelmaking coal prices in the September quarter.
  • NSWEC output rose 26%, and all FY27 coal guidance was left unchanged.
  • A fatal incident at Peak Downs and a higher strip ratio weighed on BMA's quarterly production.
  • The December quarter will show whether BMA stays on track for its FY27 guidance.

BHP Group Limited (ASX:BHP) is best known for iron ore and copper, but its coal business has become a more visible swing Factor for the BHP share price as steelmaking coal prices have moved higher. In its operational review for the September quarter, released on 20 October 2026, BHP reported an average realised steelmaking coal price of US$242.82 per tonne, up 34% on the same quarter a year earlier, while the BHP Mitsubishi Alliance (BMA) in Queensland produced 4.9 million tonnes on BHP's share and New South Wales Energy Coal (NSWEC) lifted output by 26%. FY27 coal guidance was left unchanged, so the near-term question is whether BMA can hold its production range while managing strip ratios and the aftermath of a fatal incident at Peak Downs.

BMA Production in the September Quarter

BMA produced 4.9 million tonnes of steelmaking coal in the September quarter on BHP's share, or 9.8 million tonnes on a 100% basis. That was an increase of 1% on the prior-year quarter, which BHP attributed to operational performance and mine sequencing. Compared with the June quarter, production fell 13%, reflecting a planned higher strip ratio and scheduled maintenance.

Sales were 4,821 kilotonnes, up 8% on the prior-year quarter, while production at Saraji was 846 kilotonnes, down 4%. BHP said BMA's focus remains on stabilising raw coal inventory levels and normalising the strip ratio over the medium term. The strip ratio, which measures how much waste must be moved for each tonne of coal, is a key driver of Mining costs and productivity.

The Peak Downs Fatality and Safety Response

BHP reported that operations at all BMA mines were suspended following the death of a team member at Peak Downs. Mining was suspended for one week at Peak Downs and for 24 hours across BMA's other operations. Chief Executive Officer Brandon Craig said no loss of life is acceptable.

The Peak Downs incident followed a separate fatal incident at Escondida in Chile on 23 September, which also led to a temporary suspension of mining activities. Safety performance has been a central theme of Mr Craig's early months as chief executive, and any further operational interruptions would be relevant to the delivery of guidance.

Steelmaking Coal Prices and Market Context

BHP's realised steelmaking coal price of US$242.82 per tonne in the September quarter compared with US$180.67 per tonne a year earlier and was also 4% above the June quarter. Higher realised prices directly lift Revenue from BMA, whose output is sold to steelmakers, mainly in Asia, for use in blast furnaces.

The Reserve Bank of Australia, in its November 2026 Statement on Monetary Policy, said conflict in the Middle East has pushed up energy prices and that prices for base metals and agricultural commodities have risen sharply. While the Reserve Bank did not single out coal, higher energy prices form part of the environment in which steelmaking coal is traded. On the cost side, higher fuel prices affect a business that relies on large truck fleets and rail haulage.

FY27 Coal Guidance

BHP kept BMA's FY27 production guidance at 18.5 to 20.5 million tonnes on its share, or 37 to 41 million tonnes on a 100% basis. Unit cost guidance for BMA remains US$126 to US$137 per tonne. Simple annualisation of the first-quarter result of 4.9 million tonnes gives about 19.6 million tonnes, close to the middle of the full-year range, although quarterly output can vary with mine sequencing, maintenance and weather. The 13% fall from the June quarter to the September quarter is a reminder that output within a financial year may not be evenly spread, and that a single quarter is only a partial guide to the full-year outcome.

NSWEC, which operates the Mt Arthur energy coal mine in the Hunter Valley, has FY27 production guidance of 14 to 16 million tonnes, also unchanged. It produced 4.4 million tonnes in the September quarter, up 26% on the prior-year period and 6% on the June quarter. BHP said production increased because of higher bypass coal as mining progressed into lower strip ratio areas. Bypass coal can be shipped without washing, which can reduce processing requirements and costs per tonne. NSWEC therefore offers a different exposure from BMA, as its output is thermal coal used largely for power generation rather than steelmaking.

Renewable Electricity at BMA

BMA reached a milestone in July 2026, becoming BHP's first operated Australian asset to run on 100% renewable electricity, based on current forecast demand. The shift reduces the operation's indirect emissions from purchased power, although emissions from diesel use and from coal seam methane are separate matters that require other measures.

This sits within BHP's broader effort to lower operational emissions while continuing to Supply steelmaking coal to blast furnace customers. BHP's separate steel decarbonisation partnerships with major Asian and European steelmakers are aimed at reducing emissions from the use of its products.

How Coal Fits the BHP Portfolio

Coal is smaller than iron ore and copper within BHP, but the September quarter shows how it can move group results. With copper volumes down 19% in the quarter and the realised iron ore price down 9%, the 34% lift in the realised steelmaking coal price provided a partial offset. BMA's unit costs, however, remain well above those of BHP's iron ore and copper operations, making cost control and strip ratio management particularly important when prices are volatile.

Bottom Line

BHP's coal business delivered higher realised steelmaking coal prices and steady BMA volumes in the September quarter, alongside a 26% lift in NSWEC output, with all FY27 coal guidance unchanged. The fatal incident at Peak Downs and the planned higher strip ratio weighed on BMA's quarter-on-quarter production, and BHP has said it is focused on rebuilding raw coal inventories and normalising strip ratios. For those following the BHP share price, the December quarter will show whether BMA's output stays on track for its 18.5 to 20.5 million tonne range and whether steelmaking coal prices hold near current levels.
