Story details
Mineral Resources (MinRes) reported a record 103 million tonnes of Mining Services production volumes for the three months to 30 September, up 10% from the June quarter. The company’s 23 October update says the result was supported by ramp-ups at Bald Hill and the Pilbara Hub and increased stripping at Mt Marion. This is a volume measure for its mining-services business, not 103 million tonnes of ore produced by MinRes-owned mines. The distinction is important because the company operates across contracting, iron ore and lithium, and the headline figure combines a different business activity from commodity production.
Onslow Iron shipped 9.2 million wet metric tonnes on a 100% project basis and 5.0 million tonnes attributable to MinRes. September was a record export month, with 3.49 million wet tonnes shipped. The quarterly average realised iron-ore price across Onslow Iron and the Pilbara Hub was US$83 per dry metric tonne, down 5% quarter on quarter. Onslow’s free-on-board cost was A$53 per wet tonne, below the company’s guidance range of A$54–58. These figures use different units and denominators; wet tonnes, dry tonnes and attributable volumes should not be directly compared without the stated basis.
The Pilbara Hub produced 3.2 million wet tonnes and shipped 2.9 million, with production up 55% from the previous quarter. MinRes said Lamb Creek moved from commissioning to full operations during the quarter, less than a year after ground was broken in December 2025. The company listed the fixed crushing plant, mine access road, vehicle facilities, administration buildings and a 200-person village among the infrastructure delivered. It reported a quarterly free-on-board cost of A$75 per wet tonne, within its A$74–79 guidance. Those are company operating disclosures and do not establish a long-run mine rate or cost.
Lithium was a mixed part of the quarter. Attributable spodumene production across the company’s three projects was 166,000 dry metric tonnes at 6% lithium oxide equivalent (SC6), up 17% quarter on quarter. Attributable sales reached a record 170,000 dry tonnes SC6, up 8%, at a weighted average realised price of US$1,873 per dry tonne CIF. The price fell 23% from the June quarter, which MinRes linked to lower spot lithium prices in September. The company noted that most of its lithium sales are spot-linked, so realised prices can move before lagging published indices. Record volumes therefore coincided with a lower realised price; neither result alone describes the full-year outlook.
Performance varied by operation. Wodgina produced a record 102,000 dry tonnes, up 9% quarter on quarter, with recoveries improving to 70%. Mt Marion produced 71,000 dry tonnes, down 13%, as the company described FY27 as a transitional year with planned high stripping and a higher share of lower-grade contact ore. Bald Hill produced 27,000 dry tonnes during its ramp-up; its dense-media-separation plant was commissioned and was moving toward a design capacity of 140,000 tonnes per year in Q2 FY27. These project-specific figures should not be collapsed into one trend: operations had different feed, recovery and ramp-up conditions.
The balance sheet also strengthened. MinRes said net debt fell by about A$200 million to approximately A$4.1 billion, while liquidity rose by about A$100 million to A$2.5 billion. The company attributed the net-debt reduction largely to a roughly A$170 million increase in cash, after about A$300 million of capital expenditure and payment of an approximately A$200 million FY26 dividend. Its liquidity figure included A$1.7 billion cash and an undrawn A$800 million revolving credit facility. Fitch upgraded its rating to BB stable from BB- stable in September, according to the company’s report.
MinRes maintained FY27 guidance across its divisions. It also reported higher diesel prices in September, which it expects to flow into free-on-board costs from October because of a one-month pricing lag; based on current prices, the company expected costs to remain within guidance. That is a management outlook, not a measured future cost. The quarter’s evidence is a combination of record services volumes, record attributable lithium sales, different iron-ore and lithium trends, and reduced debt. Whether these operational and financial indicators continue will depend on logistics, mine performance, commodity prices and capital spending in subsequent quarters.
