Calgary, Alberta--(Newsfile Corp. - December 22, 2025) - Copper Fox Metals Inc. (TSXV: CUU) (OTCQX: CPFX) (FSE: HPU) ("Copper Fox" or the "Company") through its wholly owned subsidiary Desert Fox Van Dyke Co., is pleased to provide an update on advancing its 100% owned Van Dyke in-situ copper recovery (ISCR) project.

The Van Dyke ISCR project is recognized as a potential near term, mid-size, environmentally friendly, sustainable copper project with a 17-year mine life and a production capacity of 85 million pounds of Grade A 99.99% pure copper cathode per year located in the center of the prolific Miami-Inspiration Mining District, Gila County, Arizona. The project is expected to provide five hundred direct and indirect jobs in the Miami-Globe area, inject approximately US$1.07 billion into the Miami-Globe and Arizona economies and contribute approximately US$355 million in mineral, state, and federal taxes over its 17-year mine life. The project has significant resource expansion potential and benefits from access to local infrastructure that includes a copper smelter, a copper rod plant, highways, rail lines, and electrical power.

Highlights

• Execution of non-binding Letters of Intent (LOI's) to purchase industrial water for leaching purposes and removal (offtake) of the Gila Conglomerate excavated from the planned underground development.
• Assembling the engineering team to complete the recently announced preliminary economic assessment (PEA) is in progress.
• Continuation and advancement of hydrogeological studies, a critical component of understanding the water flow in relation to in-situ copper recovery projects.
• Working towards the permitting process with the Town of Miami for future planned drilling activities.

Elmer B. Stewart, President and CEO of Copper Fox, stated, "The execution of these LOI's demonstrate the increasing support from the local business community and the Town of Miami towards advancing the Van Dyke project toward our stated objective to re-start copper production from this historic copper mine. These agreements provide access to a critical component of the planned leaching operations and provide an opportunity to reduce the project footprint and projected capital costs. As Copper Fox enters 2026 our focus is on completion of an updated PEA to deliver a capital efficient optimized plan to advance the project to the prefeasibility study (PFS) stage, advancing critically important hydrogeological studies and permitting of future planned drilling activities."

Letters of Intent
The LOI's with Tri-City Regional Sanitary District ("TRSD") and the Town of Miami (the "Town"), contemplates TRSD providing a portion of the industrial water needed for leaching purposes and the Town removing the Gila Conglomerate rock excavated from the planned underground access. The terms and conditions of the final agreements related to both LOI's are to be negotiated later and are contingent on the Van Dyke project achieving production.

The LOI with TRSD contemplates providing the Van Dyke project with 15% of their industrial water from its 50,000 gallon per day facility currently scheduled for completion in Q1 2027.

Mary-Anne Morano, President and CEO of TRSD stated, "We are pleased to support advancing the Van Dyke project by providing much needed industrial water for leaching purposes. The successful completion of our facility combined with the expectation that the Van Dyke project reaches production is mutually beneficial to both parties."

The LOI with the Town contemplates them taking the Gila Conglomerate, a locally occurring sedimentary rock that is commonly used for road construction purposes, excavated from the proposed access to the Van Dyke deposit for road maintenance and other construction purposes. The removal of this material from the site potentially reduces the project's infrastructure and environmental footprint by eliminating the waste rock storage facility and associated capital costs contemplated in the 2020 PEA.

Alexis Riveria, Town Manager for Miami stated, "We are pleased to continue supporting the advancement of the Van Dyke project and to have this opportunity to access this much need industrial material for the Town. This agreement is an example of two groups with a mutually vested interest working together to advance the Van Dyke project toward production which, if achieved, would have a significant long term positive impact on Miami and surrounding communities."
