Rio Tinto reported first‑quarter 2026 production results that show a 9 % year‑over‑year increase in copper‑equivalent output, driven by a 56 % rise at the Oyu Tolgoi copper mine. Total copper production reached 229,000 tonnes, while Pilbara iron ore output hit 78.8 million tonnes, bauxite fell 11 % to 13.3 million tonnes, aluminium production was 0.84 million tonnes, alumina 2.0 million tonnes, and lithium carbonate equivalent 12.7 kt.
The copper growth was supported by the continued ramp‑up at Oyu Tolgoi and a strong performance from the integrated aluminium business. Management said, "Operating excellence drove 9% YoY copper equivalent production growth across our portfolio as the Oyu Tolgoi copper mine continues to ramp up as planned and our integrated aluminium business, again, delivered a strong performance. Our Pilbara iron ore mines performed strongly, while shipments were impacted by two cyclones in the quarter." The company also highlighted that the first $650 million of annualised productivity benefits is now fully implemented, with more underway.
Iron ore shipments were reduced by roughly 8 million tonnes due to two cyclones that shut down port operations, but the company expects to recover about half of those losses in the coming months. Bauxite production declined 11 % as heavy rainfall and cyclone‑related shutdowns forced temporary closures. Despite these weather‑related disruptions, the integrated aluminium business still delivered growth, underscoring resilience in the face of supply‑chain volatility.
Safety remains a top priority after the loss of two colleagues at Simandou on February 14 and at Kennecott on March 12. Operations at both sites were suspended and are now being restarted in a phased manner. Simon Trott said, "Safety is the foundation of our business. The tragic loss of two colleagues this year, at Simandou and Kennecott, is a stark reminder that we must ensure everyone goes home safely at the end of every shift."
Rio Tinto maintained its full‑year production and cost guidance across all major divisions, signalling confidence in its execution plan. The company also highlighted progress on lithium projects, with Fenix 1B and Sal de Vida reaching mechanical completion and expected to start production in the second half of 2026. These developments reinforce the group’s strategic shift toward higher‑margin metals and support long‑term growth prospects.
Overall, the results demonstrate that Rio Tinto’s focus on operational excellence, productivity gains, and a diversified commodity mix is translating into tangible output growth. Headwinds such as cyclones, weather disruptions, geopolitical uncertainty, and higher diesel prices are being managed through robust contingency plans, while tailwinds from the Oyu Tolgoi ramp‑up, lithium milestones, and productivity benefits position the company to sustain its transformation toward a higher‑margin metals portfolio.
