Gunnison Copper Corp. 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. Such forward-looking statements relate to the intention to deploy the Nuton®?

technology at the Johnson Camp mine and future production therefrom; the continued funding of the stage 2 work program by Nuton; the details and expected results of the stage two work program; future production and production capacity from the Company's mineral projects; the results of the preliminary economic assessment on the Gunnison Project; and the exploration and development of the Company's mineral projects.
