Key Highlights

•  Attributable iron ore shipments reached a record 7.9 million tonnes, and Mining services produced a record 103 million tonnes, up 10 per cent on the June quarter.

•  Net Debt was A$4.1 billion, and the pace of reduction depends on Commodity prices and cash generation.

•  Lithium prices weakened during the quarter, and the summary did not include detailed Onslow Iron, Wodgina or Mt Marion figures.

Mineral Resources (ASX:MIN) reported record volumes across its iron ore, lithium and mining services businesses in the September 2026 quarter, the first quarter of its 2027 financial year. The Perth-based diversified miner's quarterly activity report, released on 23 October 2026, also showed a reduction in net debt and maintained full-year guidance across all divisions.

Record volumes

Attributable iron ore shipments reached 7.9 million tonnes, which the company described as a record. Its mining services division, which provides contract mining, crushing and logistics services, produced a record 103 million tonnes, up 10% on the June quarter.

In lithium, attributable sales were a record 170,000 dry metric tonnes on a 6% spodumene concentrate equivalent basis. However, achieved lithium prices fell during the quarter as spot markets weakened. Construction of a lithium flotation plant at the Mt Marion operation is progressing.

The summary did not include detailed figures for Onslow Iron shipments, realised iron ore prices or free-on-board costs, nor production volumes and costs at the Wodgina and Mt Marion lithium operations.

Balance sheet

Net debt fell by A$0.2 billion over the quarter to A$4.1 billion, while group Liquidity rose to A$2.5 billion. Capital Expenditure for the quarter was A$310 million, and the company paid a FY26 Dividend totalling A$160 million.

In September, ratings agency Fitch upgraded the company's Credit rating to BB with a stable outlook. Reducing Leverage has been an important theme for the group following its heavy Investment in the Onslow Iron project in Western Australia's Pilbara region.

Guidance and outlook

Mineral Resources maintained its FY27 production and cost guidance across all divisions and said it was on track to meet guidance in every segment. The company noted that diesel prices rose towards the end of the quarter and that fuel costs increased temporarily in September, but said it expects free-on-board costs to remain within guidance.

The company also said the planned lithium transaction with POSCO Holdings is expected to be finalised in the first half of FY27, subject to the remaining conditions being satisfied. Construction of non-processing facilities at Onslow Iron is continuing, and exploration is ongoing across both the iron ore and lithium portfolios.

On safety, the lost-time injury frequency rate fell 16% to 1.01 and the total recordable injury frequency rate improved 9% to 6.41. Regulators had also concluded an investigation with no enforcement action.

Why it matters

The results suggest the company's operations are delivering higher volumes as Onslow Iron and its mining services Business scale up, while net debt continues to edge down. Record lithium sales show Volume growth, although weaker prices limit the Earnings benefit.

For investors, the quarter highlights how the group's three businesses interact. Mining services volumes provide a base of contracted activity, iron ore adds exposure to steel demand, and lithium offers leverage to the battery Supply chain. Record volumes across all three in the same quarter are notable, but the earnings contribution from each depends on prices that the company does not control.

Risks and next steps

Net debt of A$4.1 billion remains significant, and the pace of reduction will depend on commodity prices and cash generation. Lithium prices weakened during the quarter, and iron ore prices remain a key earnings driver. Diesel costs were flagged as a pressure point, and the POSCO transaction is still subject to conditions.

Upcoming markers include completion of the POSCO transaction, progress on the Mt Marion flotation plant and Onslow Iron facilities, and December quarter delivery against maintained guidance.
