Copper Fox Highlights Significant Porphyry Copper-Molybdenum Exploration Indicators at Sombrero Butte, Advancing Permitting Plans for Testing Porphyry Target

Updated exploration model integrates geophysics, alteration, mineralogy, fluid inclusion studies, and historical drilling to define a large near-surface porphyry copper-molybdenum target in the Laramide copper province of Arizona, USA. Calgary, Alberta--(Newsfile Corp. - July 24, 2026) - Copper Fox Metals Inc.  (TSXV: CUU) (OTCQX: CPFXF) (FSE: HPU) ("Copper Fox" or the "Company") , through its wholly owned subsidiary Desert Fox Sombrero Butte Co., is pleased to present an updated exploration model for the 100% owned Sombrero Butte project in Arizona, USA. The updated model supports the interpretation that Sombrero Butte hosts a large, highly evolved porphyry copper-molybdenum system within the Laramide copper province of the southwestern United States.

The exploration model integrates the 2024 geophysical survey, recent mapping, high-resolution airborne magnetics, petrography, SWIR, whole-rock, trace-element and fertility geochemistry, fluid-inclusion observations, and historical drilling results. Collectively, these datasets define a coherent porphyry-style footprint characterized by a large chargeability anomaly, Laramide intrusive phases, potassic alteration overprinted by intense phyllic and spheroidal sericite alteration, hypersaline fluid inclusions, copper-mineralized breccias and evidence of multiple high-temperature hydrothermal events. Elmer B. Stewart, President and Chief Executive Officer of Copper Fox, stated, "The exploration results at Sombrero Butte bring together the principal geological, geophysical, mineralogical and alteration indicators expected in an Arizona Laramide-age porphyry copper-molybdenum system.

The coincidence of hypersaline fluid inclusions, spheroidal sericite, and relic potassic alteration, several hydrothermal events and a large chargeability response strength
