Gunnison Copper released a construction update for the fully permitted Johnson Camp Mine (JCM), in southeast Arizona.
“The fast pace at which our construction partners continue to progress the Johnson Camp project is nothing short of impressive,” said Robert Winton, SVP Operations.
“In roughly 12 months we will have transformed Gunnison Copper into a nimble open pit copper producer with a future as bright as the Arizona sky we enjoy daily,” added Winton.
The mining fleet had been mobilized and mining activities such as pre-stripping had begun. The JCM construction activities are progressing well and on track to produce cathode in Q3 2025.
Mining of mineralized material commenced in January 2025 and is being stockpiled in advance of the completion of the leach pad. Leach pad phase-1 is complete, and phase-2 of the leach pad follows closely behind. With phase-2 advancement, the company will begin installing Nuton’s processing equipment and ultimately start stacking sulfide and oxide production mineralized material.
The company has completely redesigned and constructed a modern laboratory for on-site material and process analysis. The lab will begin ramping up in April and will be commissioned once production from the leach pad commences.
In addition, the company’s HR group is progressing with its staffing plan, with a focus on hiring locally, and has added exceptional talent to the Gunnison team.
