Diversified miner Rio Tinto reported strong production results for 2025, posting an 8% year-on-year growth in copper-equivalent output. This robust performance was underpinned by notable gains across copper, bauxite, and lithium operations, supported by a revitalized Pilbara iron ore system.
CEO Simon Trott highlighted that these outcomes demonstrate the depth of the company’s operational discipline and project delivery expertise, with record production achieved in several commodities despite facing significant weather-related disruptions earlier in the year.
“Our operations delivered excellent results on both a quarterly and full-year basis,” Trott stated, referencing record quarterly iron ore production in the Pilbara, milestone first shipments at Simandou in Guinea, and continued progress from the ramp-up of the Oyu Tolgoi underground mine in Mongolia.
Copper stood out, with consolidated production rising 11% year-on-year to 883,000 tonnes, surpassing the upper end of Rio Tinto’s revised guidance. This increase was driven by the successful ramp-up at Oyu Tolgoi, where completion of the underground development project marks a strategic point in the group’s copper growth journey.
The combination of higher copper output, increased bauxite volumes, and expanding lithium production lifted copper-equivalent output by 8% year-on-year in 2025, while overall shipments rose by 5%. Rio Tinto noted that these achievements reinforce its positioning for a more copper-intensive future as demand associated with electrification and decarbonization continues to grow.
Within iron ore, Pilbara operations demonstrated a strong recovery from cyclone-related interruptions earlier in the year. Fourth-quarter production reached a record annualized run rate of approximately 360 million tonnes, bolstered by favorable weather and ongoing investments in mine health and productivity.
Full-year Pilbara mine production totaled 327.3 million tonnes on a 100% basis, remaining broadly stable compared to the previous year, while shipments were only 1% lower at 326.2 million tonnes—despite losing around 13 million tonnes due to cyclones in the first quarter. Strong shipping in the second half enabled the system to recover nine million tonnes of those losses. Production guidance for 2025 is set between 323 million and 338 million tonnes.
The group also emphasized initiatives to unlock additional value from its infrastructure portfolio, including a new agreement with its Hope Downs joint venture partner to access an extra 400 million tonnes of resource and ongoing discussions with BHP to jointly mine up to 200 million tonnes of iron ore across neighboring Yandicoogina and Yandi operations.
Internationally, Rio Tinto achieved a milestone at the Simandou iron ore project, marking the first shipment from the port during the fourth quarter—an accomplishment demonstrating the company’s ability to execute large-scale growth projects.
Bauxite production increased by 6% year-on-year to a record 62.4 million tonnes, representing a significant improvement in operational performance as assets mature. Aluminium and alumina output also rose, with aluminium tracking toward the higher end of guidance.
In lithium, the company recorded its highest ever quarterly output from operating assets in Argentina and made planned progress from ongoing projects as it continues developing its disciplined, high-quality lithium portfolio.
Trott concluded that these results reflect the effective implementation of Rio Tinto’s “stronger, sharper, simpler” operating model, which is delivering measurable performance improvements and value creation.
