Rio Tinto has reported a 9 per cent year-on-year increase in copper equivalent production for the first quarter of 2026, supported by gains across its manufacturing-linked aluminium and copper operations, according to its latest quarterly update.
In an ASX statement, chief executive Simon Trott said operational performance across the group’s integrated portfolio contributed to the growth, highlighting continued ramp-up at the Oyu Tolgoi copper mine and a “strong performance” from its aluminium business.
Trott said safety remained a priority following two fatalities during the quarter, noting operations at affected sites were temporarily halted and later restarted under revised conditions.
The company’s aluminium segment, which underpins downstream manufacturing supply chains, recorded a 1 per cent increase in primary aluminium production and a 6 per cent rise in alumina output year-on-year, despite weather-related disruptions to bauxite operations. Rio Tinto said the performance reflected resilience across its vertically integrated value chain.
Copper production rose 9 per cent to 229,000 tonnes, driven largely by higher output from Oyu Tolgoi, while iron ore production in the Pilbara increased 13 per cent year-on-year. However, shipments were affected by tropical cyclones, reducing volumes by an estimated 8 million tonnes, with about half expected to be recovered.
Lithium projects also progressed, with several developments achieving mechanical completion and first production expected in the second half of 2026, supporting future supply for battery and energy storage manufacturing.
Rio Tinto said its broader portfolio and global supply chain positioning helped maintain operational stability amid external pressures, including ongoing conflict in the Middle East, which has introduced uncertainty into global markets.
While commodity prices showed mixed movements during the quarter, the company reported limited direct disruption to its operations.
The company maintained its full-year production and cost guidance, stating that productivity initiatives delivering $650 million in annualised benefits have been fully implemented, with further improvements underway.
