Robust Results Reflect Resolute Rio Resolve

Global miner Rio Tinto revealed a remarkable Q2 2025, achieving a 13% uplift in copper equivalent production year-on-year & a 6% rise for the half year. Chief Executive Jakob Stausholm praised record bauxite production, higher copper volumes & successful ramp-up at Oyu Tolgoi, Mongolia. The company’s strategy aims to diversify operations beyond iron ore, strengthen copper, bauxite & lithium portfolios, and ensure profitable growth while adapting to shifting commodity demand.

Bauxite Bonanza Bolsters Business Balance

Rio Tinto’s bauxite business hit a second consecutive quarterly record, with output rising to 15.6 million metric tons, up 6% year-on-year. This positions production at the higher end of full-year guidance between 57 & 59 million metric tons. Increased bauxite supplies support alumina production, stabilise aluminium smelting, and reinforce Rio’s strategy to secure raw material chains, given rising demand from low-carbon transport & packaging sectors.

Copper Catalysts Cultivate Continued Climb

Copper production reached 229 thousand metric tons, up 15% year-on-year & 9% from the previous quarter, driven by Oyu Tolgoi’s ramp-up and the Arcadium acquisition. Full-year copper production now tracks the higher end of guidance, between 780 & 850 thousand metric tons. Improved unit costs further strengthen margins as global demand for copper surges amid renewable energy & electric vehicle investment.

Iron Increases Inspire Investor Interest

Pilbara iron ore production reached 83.7 million metric tons, a 5% rise year-on-year & a 20% surge from Q1. Shipments recovered from earlier weather impacts, at 79.9 million metric tons. With first shipments from Guinea’s Simandou expected around November 2025, Rio Tinto diversifies its iron ore portfolio, targeting 0.5 to 1.0 million metric tons this year & tapping high-grade supply crucial for greener steelmaking.

Aluminium & Alumina Achieve Ascendant Aims

Alumina production rose 8% to 1.8 million metric tons, while aluminium output edged up 2% to 0.84 million metric tons. Rio expects aluminium to stay within the 3.25 to 3.45 million metric tons guidance, supported by steady power supply & asset improvements. Rising demand for low-carbon aluminium, especially from carmakers & packaging firms, aligns with Rio’s investment in renewable power & smelter efficiency.

Lithium Leap Lays Long-Term Leverage

Integration of lithium assets proceeds as planned, aiming to establish a world-class business. Rio’s strategy positions lithium as a future growth pillar, vital for batteries & renewable storage. Early focus on project design & sustainability ensures compliance with global standards and opens doors to emerging electric vehicle markets.

Strategic Simandou Shipments Strengthen Supply

The Simandou project in Guinea accelerates, with first shipments brought forward to around November 2025. Expected volumes of 0.5 to 1.0 million metric tons mark the start of Rio’s push into high-grade West African iron ore. Alongside Pilbara, this diversifies supply, lowers average carbon intensity per ton, and supports global steelmakers’ decarbonisation.

Key Takeaways:

• Copper equivalent production surged 13% in Q2 2025, driven by copper & bauxite.

• First Simandou shipments expected by November, diversifying iron ore sources.

• Bauxite & copper production trends now at higher end of Rio’s annual guidance.
