MiningArizona, United States51-200 Employees

Gunnison Copper is a mining company based in Phoenix, Arizona, focused on operating and developing copper mines in Southern Arizona to supply copper cathode that is produced entirely in the United States for domestic energy, defense, and manufacturing supply chains. It emphasizes local hiring, local procurement, and local sales, while maintaining a commitment to safety, responsible operations, and long-term value for stakeholders. The Johnson Camp Mine is currently in production, delivering US-produced copper cathode, and the company is collaborating with Nuton LLC, a Rio Tinto venture, to apply bioleaching technologies to expand output and unlock sulfide potential.

The Gunnison Project, described in a comprehensive assessment, contemplates a large open-pit operation south of the Johnson Camp Mine that would use conventional open-pit mining, heap leach, and SX/EW processes to produce very high-purity copper cathode for U.S. energy, data center, manufacturing, and defense supply chains. The plan anticipates an average annual production of 174 million pounds of copper cathode for the first 15 years, with a total of 3.2 billion pounds over a 21-year mine life. In 2026 Gunnison Copper joined the Defense Industrial Base Consortium to strengthen domestic supply chains for critical minerals and defense-related technologies.
