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.

Gunnison exists to develop and operate copper mines in Southern Arizona to produce fully Made in America finished copper cathode to directly supply American energy, defense, and manufacturing supply chains. Gunnison proudly hires locally, purchases locally, and sells its products in America. Gunnison invests in its employees, their families, and the communities around it. Gunnison operates safely and responsibly with a focus on technology and positive societal impact, while also emphasizing long-term value creation for stakeholders.

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 a preliminary economic assessment ("PEA") 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 expected in Q3 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.

For additional information on the Gunnison Project, including the PEA and mineral resource estimate, please refer to the Company's technical report entitled "Gunnison Project NI 43-101 Technical Report Preliminary Economic Assessment" dated effective November 1, 2024 and available on SEDAR+ at www.sedarplus.ca.
