Gunnison Copper Advances Toward NYSE American Listing as Copper Reaches Record Highs

TSX: GCU | OTCQB: GCUMF | FSE: 3XS0

Gunnison Copper Corp. announced that it has received pre-clearance for a proposed NYSE American listing under the ticker "GUNN," with trading expected in late October 2026, subject to SEC registration effectiveness and final listing approvals, according to the company. The proposed listing would broaden U.S. investor access to the company, which is headquartered in Phoenix, Arizona, with mining and development assets entirely in Arizona, and which the company states is supplying the U.S. defense sector and Amazon Web Services today.

According to the press release, the proposed listing would complement Gunnison's existing Toronto Stock Exchange listing, with the company's common shares continuing to trade on the TSX under the symbol "GCU."

Key Listing and Growth Details

Proposed NYSE American Listing and ADR Program

• Gunnison has received pre-clearance for a proposed NYSE American listing under the ticker "GUNN," with trading expected in late October 2026, subject to SEC registration effectiveness and final listing approvals.
• The company intends to establish a Level II American Depositary Receipt ("ADR") program, with each ADR representing thirty-five (35) common shares of the company.
• The ADRs are expected to trade on NYSE American under the ticker symbol "GUNN."
• Gunnison's common shares would continue to trade on the TSX under the symbol "GCU."
• Establishment of the Level II ADR program and the NYSE American listing remain subject to the filing and effectiveness of applicable registration documentation with the SEC, satisfaction of all applicable NYSE American listing requirements, receipt of applicable regulatory approvals, and other customary conditions, according to the company. Pre-clearance does not constitute final listing approval.
• According to the press release, there can be no assurance that the proposed ADR program or NYSE American listing will be completed on the terms currently contemplated, within any anticipated timeframe, or at all.

Production Base and Growth Potential

• Gunnison's Johnson Camp Mine has annual production capacity of up to 25 million pounds of finished copper cathode, according to the company.
• The flagship Gunnison Project's March 2026 preliminary economic assessment ("PEA") estimates average annual production of 174 million pounds during its first 15 years, according to the company.
• The company states this creates the potential for combined annual output that is nearly eight times Johnson Camp's nameplate capacity, subject to development of the Gunnison Project and continued operation of Johnson Camp at capacity.
• 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.

Defense and AI Infrastructure Supply

• Gunnison is a member of the Defense Industrial Base Consortium, supporting what the company describes as its commitment to strengthening America's defense supply chains.
• The company also directly supplies Amazon Web Services with copper for data center construction, according to the press release.

Execution Track Record

• Gunnison brought Johnson Camp from construction decision to production in under 18 months, according to the company.
• The company intends to apply the same urgency and execution discipline to advancing the Gunnison Project, pursuing opportunities to accelerate engineering, permitting and development, according to the press release.

Domestic Supply Chain

• Johnson Camp mines American mineralized material and processes copper in Arizona, producing finished copper cathode on-site without sending material overseas for smelting or refining, according to the company.
• The Gunnison Project is being designed around the same model, according to the press release.

"Copper connects some of America's most powerful investment themes: artificial intelligence, electrification and national defense," said Craig Hallworth, President and Chief Executive Officer of Gunnison Copper. "We are supplying the U.S. defense sector and Amazon Web Services today, while advancing a project with the potential to transform our production scale. With copper prices reaching record highs, we believe the opportunity to build a larger American copper business is compelling."

"We brought Johnson Camp from construction decision to production in under 18 months, an exceptionally fast timeline that demonstrates our ability to execute with urgency and discipline. We intend to bring that same urgency to accelerating the Gunnison Project. Our proposed NYSE American listing would give more American investors access to the growth we are working to deliver."

Market Note: Level II ADR Programs and NYSE American Listings

According to the press release, an American Depositary Receipt ("ADR") program allows a non-U.S. company's shares to trade on a U.S. exchange through a depositary structure, with each ADR representing a fixed number of underlying common shares, in Gunnison's case thirty-five (35) common shares per ADR. A Level II ADR program, as described by the company, involves listing on a U.S. national securities exchange, which requires filing and effectiveness of registration documentation with the SEC and satisfaction of the exchange's listing requirements, in addition to the company's existing TSX listing, which would continue unaffected.

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 23%, 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.
