Copper Fox Metals Reports Additional Mineralized Intervals Advancing the Van Dyke ISCR Project

About this update from Copper Fox Metals Inc.

Calgary, Alberta--(Newsfile Corp. - May 26, 2026) - Copper Fox Metals Inc. (TSXV: CUU) (OTCQX: CPFXF) (FSE: HPU) ("Copper Fox" or the "Company"), through its wholly owned subsidiary, Desert Fox Van Dyke Co., is pleased to report the final analytical results from the previously announced historical diamond drill core sampling program (see news release dated April 21, 2026). The program was designed to further define the limits of total soluble copper ("TSCu") mineralization and the mineralogical domains within the Van Dyke copper deposit. The Van Dyke in-situ copper recovery ("ISCR") project is 100%-owned by Copper Fox and is located in the Globe-Miami Mining District, Gila County, Arizona. This news release reports analytical results for 18 drill holes, 15 of which returned intervals exceeding the TSCu cutoff of 0.025% (ASCu% + CNCu%) used in the 2020 mineral resource estimate ("MRE"). Analytical results have now been received for all 29 drill holes included in the 2026 core sampling program. Highlights DDH M-2 returned a 53.80-metre core interval (272.19 m to 325.98 m) averaging 0.543% total copper ("TCu") and 0.416% TSCu, including a 34.60-metre interval averaging 0.725% TCu and 0.592% TSCu. DDH OXY-46 returned a 74.60-metre core interval (286.51 m to 361.19 m) averaging 0.273% TCu and 0.223% TSCu, including a 19.51-metre interval averaging 0.518% TCu and 0.453% TSCu. Completion of the preliminary 3D groundwater flow model for the Bloody Tanks Wash drainage basin has materially advanced the Company's understanding of the Van Dyke project hydrogeology. Work on the updated PEA is progressing across resource estimation, cost modelling, engineering, geotechnical, water treatment and hydrogeological studies. Ground water monitoring indicates water quality parameters, water level measurements, analytical results and VWP data are consistent with that observed in previous quarters. Elmer B. Stewart, President and CEO of Copper Fox, stated, "The positive results from the drill core sampling program have expanded the limits of the total soluble copper envelope at the Van Dyke copper deposit and could influence the updated mineral resource estimate, a critical component of the revised PEA. An updated mineral resource and improved definition of the mineralogical domains are important to optimizing the underground access concept and wellfield layout in support of th...
