About Rio Tinto plc

Rio Tinto plc is a leading global mining group that produces iron ore, copper, aluminium, lithium and other materials essential for infrastructure, energy and technology. Its operations span Australia, Canada, Mongolia, the United States, South America and Africa.

LSE:RIO has a 2.57% weighting in the FTSE 100 and a Market Capitalisation of about £109.4 billion. The group is among the largest companies in the index.

Iron Ore

Pilbara sales on a 100% basis were 85.7 million tonnes in the third quarter, up 2% year on year and flat on the previous quarter. For nine months, sales were 243.3 million tonnes, up 4%, and full-year guidance of 323 to 338 million tonnes is unchanged.

Iron ore remains a core part of the business, supplying steel makers who build cities and infrastructure around the world.

Copper

Consolidated copper production was 205 thousand tonnes in the third quarter and 646 thousand tonnes for nine months, up 1%. Full-year guidance of 800 to 870 thousand tonnes is unchanged.

Oyu Tolgoi in Mongolia was a highlight, with output up 27% year on year in the third quarter and 29% for the year to date, running at an annualised rate of around 450 thousand tonnes in the quarter.

Aluminium and Bauxite

Bauxite production was 15.7 million tonnes in the third quarter, and primary aluminium production was 0.8 million tonnes. Full-year guidance is 58 to 61 million tonnes for bauxite and 3.25 to 3.45 million tonnes for aluminium, both unchanged.

Lithium

Lithium carbonate equivalent production was 13.0 thousand tonnes in the third quarter, up 4% year on year, and 40.3 thousand tonnes for nine months, up 33%. Guidance for the year is 61 to 64 thousand tonnes.

The growth in lithium reflects the group's efforts to build a position in materials needed for batteries and the energy transition.

Why Diversified Mining Matters

A portfolio that spans iron ore, copper, aluminium and lithium allows the company to serve different end markets, from construction and Manufacturing to electric vehicles and renewable energy. Copper in particular is used widely in power grids, motors and electronics.

Scale, long-life Assets and operating expertise are central to the model. The group also invests in innovation, such as automation and low-carbon processing, to improve productivity.

Safety and Communities

Safety is the company's first priority, and it reports regularly on safety performance. It works with Indigenous peoples and local communities where it operates, and it has set targets for emissions reduction and water stewardship.

Iron Ore Operations

The Pilbara in Western Australia is the group's largest iron ore region, with mines, rail and port infrastructure operating as an integrated system. The scale of the operation and the quality of the ore make it a leading supplier to steel makers in Asia.

Rio Tinto has been investing in automation, including autonomous trains and trucks, to improve safety and productivity.

Copper and Critical Minerals

Copper is a growing part of the portfolio, with operations in Mongolia, the United States and Chile and a pipeline of projects. Demand for copper is expected to increase as economies electrify, build renewable generation and expand data centres.

The group is also building a position in lithium, which is used in batteries for electric vehicles and energy storage. Lithium output of 40.3 thousand tonnes in nine months, up 33%, shows early progress in this area.

Factors to Monitor

Investors following LSE:RIO may watch quarterly production against guidance, Oyu Tolgoi ramp-up, Commodity prices, progress in lithium and full-year results.

Conclusion

Rio Tinto plc moved 1.11% lower to 6,314.0p today following third-quarter production results showing 85.7 million tonnes of iron ore shipped, 27% growth in Oyu Tolgoi copper and unchanged 2026 guidance. Diversification across essential materials remains the central theme. Future company announcements should provide further detail on operating progress, capital allocation and management priorities.
