Gunnison Copper Corp. (TSX: GCU) (OTCQB: GCUMF) (FSE: 3XS0) is pleased to announce that President and CEO Craig Hallworth and People First Leader Alex Bovell recently met with the Honorable Katie Hobbs, Governor of Arizona, in recognition of the Company’s partnership with the State of Arizona and its approval under the Arizona Commerce Authority’s Qualified Facility Tax Credit Program.

The meeting follows Gunnison’s May 2026 announcement that its Arizona operations had been approved under the QFTC Program, providing the Company with access to non-dilutive, refundable state income tax credits tied to qualifying capital investment and job creation. Gunnison created 81 qualifying jobs during the 2025 tax year and expects to receive US$1.62 million in cash from refundable tax credits in Q4 2026. The Company expects to create an additional 19 qualifying jobs during the 2026 tax year and receive a further US$0.38 million in refundable tax credits in Q4 2027. In total, the program is expected to provide Gunnison with US$2.0 million in non-dilutive cash funding based on the creation of 100 jobs at Johnson Camp.

The QFTC Program is designed to encourage investment in Arizona manufacturing facilities while creating high-quality employment opportunities in the state. Gunnison’s approval under the program supports the Company’s mission to produce American copper in Arizona while creating high-quality local jobs and strengthening domestic supply chains.

Gunnison has delivered on those commitments through the ramp-up of its Johnson Camp Mine, where the 81 jobs created during the 2025 tax year are supporting employment and economic activity in southern Arizona. JCM is producing copper cathode, while Gunnison continues to advance its flagship Gunnison Project toward development.

Craig Hallworth, President and CEO of Gunnison Copper, commented:

“It was a privilege to meet with Governor Hobbs and personally thank her for her leadership and strong support for job creation, economic development and responsible mining in Arizona. We are sincerely grateful to the Governor, her administration and the Arizona Commerce Authority for their partnership and recognition of Johnson Camp’s contribution to Cochise County and the State. We look forward to building on this partnership as we continue investing in Arizona and advance the much larger Gunnison Project.”

Governor Katie Hobbs commented:

“Gunnison Copper’s investment at Johnson Camp is creating high-quality jobs in Cochise County and strengthening Arizona’s position as a leader in American copper production,” said Governor Katie Hobbs. “My administration is committed to delivering opportunity to Arizonans in rural communities, and these jobs demonstrate the tangible benefits of our partnership with Gunnison and the Arizona Commerce Authority. Together we are bolstering Arizona’s manufacturing economy and critical supply chains.”

The QFTC approval forms part of Gunnison’s growing track record of government support as the Company advances its U.S. copper production and development strategy. The Company continues to engage with state and federal agencies on opportunities that support domestic critical mineral production, manufacturing and secure U.S. supply chains.

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 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.
