Baystreet.ca - Baystreet - Thu Dec 4, 2025

Announced that Rio Tinto has successfully produced the first copper from the Johnson Camp mine in Arizona using its Nuton® Technology, marking a pivotal step forward in the development of this innovative copper processing technology. After more than 30 years of research and development, the first copper cathode using Rio Tinto's proprietary bioleaching technology, which relies on microorganisms grown on site, was produced at Gunnison Copper's Johnson Camp mine last month. The deployment involves the design and delivery of a technology package for a heap leach pad targeting production of approximately 30,0001 tonnes of refined copper over a four-year demonstration period. Rio Tinto is engaging with several potential customers in the U.S. to support the domestic copper supply chain. Gunnison Copper Corp. shares T.GCU are trading up 2 cents at $0.39.
