Global mining group Rio Tinto’s second quarter 2025 results show strong operational performance, led by record output from its bauxite business, which achieved a second consecutive quarterly high and is now tracking toward the upper end of full-year production guidance. Oyu Tolgoi also continued its ramp-up, positioning it to become the world’s fourth-largest copper mine by the end of the decade.
The company is also advancing key growth projects, recording its highest Q2 production from the Pilbara iron ore mine since 2018 following recovery from Q1 weather disruptions. In Guinea, development of the Simandou high-grade iron ore project is ahead of schedule, with 0.5 to 1.0 Mt of shipments expected in 2025.

Copper equivalent production rose 13% in Q2 YoY, and 6% YoY for the half year, driven by strong performance in the copper business and the contribution of the acquisition of Arcadium Lithium. Copper production is now expected at the higher end, and copper unit costs around the lower end of full year guidance ranges.
The integration of Arcadium Lithium is progressing as planned, aligning with Rio Tinto’s strategy to build a world-class lithium business. The company is also advancing its iron ore replacement strategy, with the Western Range iron ore mine opening on schedule and within budget, and the Hope Downs 2 project securing all necessary government approvals.
Chief executive Jakob Stausholm says: “We delivered excellent operational performance from our mine operations. We will continue to drive progress towards our long-term strategy to deliver profitable growth and build a stronger, more diversified business.”
