Strengthening America's Defense and Critical Mineral Supply Chains
Gunnison's NYSE American debut comes amid increasing U.S. government focus on securing domestic critical mineral production and reducing reliance on foreign supply chains.
Last week, Gunnison welcomed U.S. Secretary of the Interior Doug Burgum and Congressman Juan Ciscomani to its producing Johnson Camp Mine in Cochise County, Arizona, highlighting the strategic importance of American copper production to national security, industrial competitiveness and the nation's economic future.
The visit underscored the growing alignment between Gunnison's mission and federal priorities to strengthen domestic mineral production, support American manufacturing and secure critical supply chains. At Johnson Camp, Gunnison mines, processes and produces finished copper cathode on-site, eliminating the need for overseas smelting or refining.
A Significant American Copper Growth Opportunity
Beyond current production, Gunnison is advancing its flagship Gunnison Copper Project, located approximately 1.5 miles from Johnson Camp.
The Company's March 2026 Preliminary Economic Assessment outlined:
- ~175 million pounds of average annual copper production over a 21 year mine life.
- More than 3.2 billion pounds of copper production over the life of mine.
- US$2.0 billion after-tax NPV (8%), with a 22.5% IRR and 3.9-year payback, based on US$4.60/lb copper.
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.
The flagship Gunnison Project represent a significant opportunity to expand American copper production and strengthen long-term domestic supply security.
"America's future depends on securing the critical minerals needed to power our economy, defend our nation and support the next generation of technology," concluded Hallworth. "Gunnison is proud to be part of that future. With our NYSE American listing, we are opening the door to a broader U.S. investor base as we continue building a leading American copper company."
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 main pit Measured and Indicated Mineral Resource containing over 846 million tons with a total copper grade of 0.33% containing 5.19 billion pounds of copper (Measured Mineral Resource of 192 million tons at 0.37% containing 1.42 billion pounds of copper and Indicated Mineral Resource of 655 million tons at 0.31% containing 3.77 billion pounds of copper).
The Strong & Harris satellite deposit, located approximately 1.9 miles from the Gunnison processing facilities, is also included in the mine plan and hosts an Inferred Mineral Resource of 76 million tons grading 0.49% total copper (0.32% CuOx) at a 0.07% cutoff, 0.56% zinc and 0.12 oz/ton silver, containing approximately 740 million pounds of copper, including 483 million pounds of oxide copper, as well as zinc (856 million pounds) and silver (9.0 million ounces).
A preliminary economic assessment ("PEA") was completed in March 2026 for the Gunnison Project yielding robust economics including an NPV8% of $2 billion, IRR of 22.5%, and payback period of 3.9 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 South Star, and eight other deposits.
