AWS to use Rio Tinto copper for datacenters

AWS

AWS to use Rio Tinto copper for datacenters under a new two-year partnership. The deal links Arizona cathode output to US data center buildouts. Meanwhile, AWS will support Nuton with cloud tools for leaching optimization.

Nuton produces 99.99pc copper cathodes at the Johnson Camp mine in Arizona. Nuton uses proprietary bioleaching to extract copper from primary sulfide ore. AWS to use Rio Tinto copper for datacenters as the project moves from first metal to scale.

Nuton’s bioleaching links copper supply to AI infrastructure

Nuton positions bioleaching as a lower-footprint route for refined copper in the US. Gunnison produced its first copper cathode from the project in August. Therefore, the partnership arrives as operators seek reliable domestic metals for electrification and AI demand.

Nuton expects the project to produce 30,000t of refined copper over four years. Nuton expects 14,000t to come from its bioleaching technology. AWS to use Rio Tinto copper for datacenters as volumes build and specifications stay tight.

AWS simulations target higher recovery with lower water and acid use

Nuton will use AWS platforms to simulate performance and improve recovery predictions. The workflow aims to optimize water and acid consumption across the leaching circuit. As a result, Nuton can tune operating parameters faster and reduce trial-and-error.

The partners also build a repeatable digital template for future leaching deployments. Nuton and Gunnison previously secured $13.9mn in DOE tax credits to support domestic copper output. Therefore, the project fits a broader push to localize critical materials supply chains.

The Metalnomist Commentary

This partnership ties “digital mine” methods directly to refined copper supply for hyperscale infrastructure. However, the real test will be consistent recoveries across variable sulfide feeds. If Nuton proves repeatability, bioleaching could win a larger share of US copper growth.
