Gunnison Copper Corp has reached a major milestone with the first production of pure copper cathode at its fully operational Johnson Camp Mine (JCM) in southeast Arizona. Senior Vice President of Operations Robert Winton shared the news with Steve Darling from Proactive, noting that production officially commenced during the last week of August 2025, establishing Gunnison as the newest American copper producer.

The start of domestic production represents a pivotal achievement for both the company and the United States, as it strengthens energy independence, national defense readiness, and advanced manufacturing supply chains.

Winton explained that Gunnison successfully commissioned and brought online the solvent extraction and electrowinning (SX-EW) circuit, marking the transition from start-up to sustained copper production from run-of-mine ore. Importantly, the company achieved this milestone ahead of schedule, with Made-in-America copper now ready for domestic sales.

A key contributor to this success has been Nuton, Gunnison’s strategic and financial partner. Nuton has provided not only capital support but also exclusive access to its proprietary leaching technologies, enabling a more sustainable and economically viable pathway for copper recovery at JCM.

Equally noteworthy, Winton emphasized the company’s commitment to safety and operational excellence. The commissioning of the run-of-mine copper production circuit was completed without incident, underscoring Gunnison’s strong safety culture and disciplined execution.

With first copper now produced, Gunnison is poised to expand production capacity and play an increasingly important role in securing a domestic copper supply chain critical for the energy transition, electrification, and national infrastructure.
