Gunnison Copper Announces That Rio Tinto and Amazon Web Services Collaborate to Bring Low-Carbon Nuton Copper from Gunnison's Johnson Camp Mine to U.S. Data Centers

Amazon and Rio Tinto Validate Gunnison’s "Low-Carbon" Copper via Strategic Data Center Supply Chain Integration

Executive Summary

On January 15, 2026, Gunnison Copper announced a high-profile collaboration between Rio Tinto’s Nuton Technology and Amazon Web Services (AWS). Key components include: - AWS will utilize the first "Nuton copper" produced at Gunnison’s Johnson Camp Mine (JCM) in components for its U.S. data centers. - AWS will provide cloud-based data and analytics to optimize Nuton’s bioleaching technology currently deployed at JCM. - This represents the first commercial application of Nuton’s proprietary technology in a major tech supply chain, focusing on the "low-carbon" and "Made-in-America" credentials of the copper produced.

Material Impact

This news is a significant de-risking event and a commercial "Game Changer" for a junior producer. - Validation of Product: Having a global titan like Amazon as an end-user validates the commercial quality and environmental claims of the Nuton bioleaching process. - Strategic Moat: The "low-carbon" designation allows Gunnison to command interest from ESG-focused tech buyers, potentially leading to premium pricing or guaranteed offtake as data center demand for electrical infrastructure surges. - Operational Optimization: The integration of AWS cloud analytics provides Nuton (and by extension, Gunnison) with advanced tools to improve recovery rates and lower costs, which is critical given the low-grade nature of the resource (0.31% Cu). - Supply Chain Security: It reinforces the "domestic supply" narrative, aligning the company with U.S. national interests and the Inflation Reduction Act goals.
