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 ("PEA") 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.

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
