(TSXV: CUU) (OTCQX: CPFXF) (FSE: HPU) (\"Copper Fox\" or the \"Company\"), through its wholly owned subsidiary Desert Fox Van Dyke Co., is pleased to provide the results of the Preliminary Geometallurgical Model completed by Samuel Engineering on its 100% owned Van Dyke in-situ copper recovery (ISCR) project located in the Globe-Miami Mining District, Gila County, Arizona (see news release dated June 23, 2025). In 2020, Copper Fox announced the results of an updated Mineral Resource Estimate (MRE) and Preliminary Economic Assessment (PEA) on Van Dyke using a US$3.15/lb copper price for the Base Case economic model. The PEA indicates annual production of 85 million pounds of Grade A copper cathode, at full capacity, utilizing the ISCR and solvent extraction and electrowinning (SX/EW) process. The study highlighted the following:Project economics sensitive to copper price, Significant exploration potential to increase resource base, and A recommendation to advance the project to prefeasibility study (PFS) stage. Preliminary Geometallurgical Model (PGM) The PGM achieved three critical components for developing an updated geometallurgical model to support the completion of a PFS level of investigation by identifying the mineralogical domains (zones) in the Van Dyke deposit, \"data gaps\" in the project metallurgical results across the deposit and developed recommendations for future metallurgical testing.Elmer B. Stewart, President and CEO of Copper Fox, stated, \"The PGM has identified the data gaps in the metallurgical coverage across the Van Dyke deposit and recommendations for future sampling to gain greater certainty on the metallurgical variability across the Van Dyke deposit. The PGM is a critical part of the Execution Plan that maps out the scope, timing and estimated cost of the studies required to meet the threshold of a PFS level study.\"Mineralogical DomainsThe mineralogical domains identified in the Van Dyke deposit are consistent with the general description of \"Supergene\" copper deposits (see Figure-1 and Table-1). At Van Dyke, the oxide and transition zones are the main zones of interest. Below the transition/chalcocite zones the mineralization, where p...
