Michael Fox interviews Craig Hallworth, CFO of Gunnison Copper (TSX: GCU) (OTCQB: GCUMF) (FSE: 3XS0), to discuss the company’s focus on copper development and production in southern Arizona. Craig details Gunnison Copper as a pure-play copper developer with their flagship Gunnison Copper Project aiming for 170 million pounds of copper cathode annually at a $1.94 per pound cost. He highlights a partnership with Rio Tinto’s Nuton LLC using innovative sulfide leaching technology at the Johnson Camp mine, targeting production by year-end. They explore copper’s critical role in the U.S. economy amid supply deficits and strengthening government support. The conversation covers the U.S. copper processing shortfall, innovations like the Nuton process that eliminate smelting and cut costs, and the upcoming January 2026 Preliminary Economic Assessment update for Gunnison’s flagship project, signaling promising progress and investment potential.
ABOUT GUNNISON COPPER
Gunnison Copper Corp. is a multi-asset pure-play copper developer and producer that controls the Cochise Mining District (the district), containing 12 known deposits within an 8 km economic radius, in the Southern Arizona Copper Belt.
Its flagship asset, the Gunnison Copper Project, has a Measured and Indicated Mineral Resource containing over 831.6 million tons with a total copper grade of 0.31% (Measured Mineral Resource of 191.3 million tons at 0.37% and Indicated Mineral Resource of 640.2 million tons at 0.29%), and a preliminary economic assessment yielding robust economics including an NPV8% of $1.3 billion, IRR of 20.9%, and payback period of 4.1 years. It is being developed as a conventional operation with open pit mining, heap leach, and SX/EW refinery to produce finished copper cathode on-site with direct rail link.
The PEA is preliminary in nature and includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the conclusions reached in the PEA will be realized. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
In addition, Gunnison’s Johnson Camp Asset, which is now in production, is fully funded by Nuton LLC, a Rio Tinto Venture, with a production capacity of up to 25 million lbs of finished copper cathode annually.
Other significant deposits controlled by Gunnison in the district, with potential to be economic satellite feeder deposits for Gunnison Project infrastructure, include Strong and Harris, South Star, and eight other deposits.
