Rio Tinto (RIO -0.09%) is a diversified global mining company based in the U.K. It produces aluminum, copper, diamonds, gold, industrial minerals, iron ore, and uranium. It also produces other basic materials, including borates, lithium, salt, and titanium dioxide. It was the world's top iron ore producer and the tenth-largest copper miner, based on its 2025 output. Copper accounts for about 39% of its earnings.
The company's copper business consists of two large-scale mining operations:
- Rio Tinto operates the Kennecott mine in Utah. The world-class copper mine also produces silver and gold.
- The company has a 66% interest in Oyu Tolgoi, a copper and gold deposit in Mongolia, one of the world's largest known deposits. By 2030, Oyu Tolgoi should be the world's fourth-largest copper-producing mine.
Rio Tinto has several copper-related growth projects in the pipeline, including Resolution Copper in the U.S. and Winu in Australia. Discovered in 2017, the Winu copper and gold resource has the potential to become a large-scale mining operation. In 2025, Rio Tinto signed an agreement with Sumitomo Metal Mining to jointly develop its Winu copper-gold project. Meanwhile, Rio Tinto and BHP Group expect to open the Resolution Copper mine by the mid-2030s.
In early 2026, Rio Tinto signed a deal with Amazon (AMZN -1.78%) to supply it with copper for data center construction. Rio Tinto will deploy a new method that uses bacteria and acid to extract copper from low-grade deposits previously uneconomical to process. Amazon and other data center developers need a lot of copper for wiring, busbars, circuit boards, transformers, and other electrical components used in AI data centers.
