RIO Continues to Increase Copper Production: What's the Road Ahead?
Read MoreHide Full Article
Key Takeaways
RIO's Q4 copper output rose 5% YoY; 2025 production reached 883 kt, driven by strong asset performance.
Rio Tinto produced the first copper at Arizona's Johnson Camp using Nuton technology.
RIO's 2025 copper growth was aided by Oyu Tolgoi ramp-up and strong Kennecott output.
Rio Tinto Group (RIO - Free Report) reported solid growth in copper production in the fourth quarter of 2025. Per the production results, the company’s consolidated copper output increased 5% year over year in the fourth quarter. The results were supported by strong performance across its operating assets.
The company is making steady progress across its growth pipeline. In December 2025, it achieved its first copper production at the Johnson Camp mine in Arizona using its proprietary Nuton technology. This marks a significant milestone for Rio Tinto, as Nuton enables cleaner, faster and more efficient copper recovery at an industrial scale.
The Johnson Camp deployment includes the design and delivery of a heap leach technology package, targeting approximately 30,000 tons of refined copper over a four-year demonstration period. Through the use of Nuton technology, Rio Tinto aims to produce copper with the lowest carbon footprint in the United States at the Johnson Camp.
Also, the company is actively collaborating with U.S. customers to strengthen the domestic copper supply. Rio Tinto’s total copper production reached 883 kilotonne (kt) in 2025, up 11% on a year-over-year basis. The results were supported by the solid ramp-up at the Oyu Tolgoi site and strong performance at the Kennecott mine.
