About Gunnison Copper Corp.

Gunnison Copper is a multiasset pure-play copper developer and producer that controls the Cochise mining district (the district), containing 12 known deposits within an eight-kilometre 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 per cent (measured mineral resource of 191.3 million tons at 0.37 per cent and indicated mineral resource of 640.2 million tons at 0.29 per cent), and a preliminary economic assessment (PEA) yielding robust economics, including a net present value (NPV) at 8 per cent of $1.3-billion, an internal rate of return (IRR) of 20.9 per cent and a 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 financed by Nuton LLC, a Rio Tinto venture, with a production capacity of up to 25 million pounds 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 Nov. 1, 2024, and available on SEDAR+.
