Gunnison Copper Corp. Mobilizes Mining Fleet at the Johnson Camp Mine in SE Arizona

Further to the construction update from the press release dated August 8^th, 2024, where it was announced construction of the new leach pad, including crushing of the over-liner material, had commenced the Company is pleased to report that the mining fleet has been mobilized, and mining activities such as pre-stripping have begun.

Construction of the Johnson Camp Mine is fully funded by Nuton LLC ("Nuton"), a Rio Tinto venture. Gunnison is the owner and operator of the mine which has a production capacity of up to 25 million pounds of copper cathode per year to directly supply critical American supply chains in the clean energy, defense, and manufacturing sectors.

"We are extremely pleased with how well the JCM construction is progressing. We are tracking our major construction milestones and budget, including mobilization of the mining fleet and leach pad construction. The successful start of mining activities was made possible by our highly talented local workforce of over 150 employees and third party contractors, reflecting our commitment to workforce development and local area economic stimulus," comments Robert Winton, SVP Operations and General Manager of Gunnison Copper. "From concept to first production measured in months is a testament to our partnership with Nuton and the support of the 3 engineering firms contributing to this industry first."

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 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 yielding robust economics including an NPV8% of $1.3Billion, 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 under construction with first copper production in H1 2025, 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.
