Copper Fox Intersects Porphyry Copper System at Mineral Mountain

Calgary, Alberta--(Newsfile Corp. - April 7, 2026) - Copper Fox Metals Inc. (TSXV: CUU) (OTCQX: CPFXF) (FSE: HPU) ("Copper Fox" or the "Company") and its wholly owned subsidiary, Desert Fox Mineral Mountain Co. ("Desert Fox"), are pleased to report that diamond drillhole (DDH) MM-01-2025 intersected the outer propylitic zone of a blind porphyry copper system. The overlapping, mixed assemblages of early stage, high temperature chalcopyrite-bornite-molybdenite veins with early potassic and later sericitic envelopes and lower temperature pyrite-epidote-chlorite veins with sericitic and propylitic envelopes indicate the broad spectrum of hydrothermal temperature and oxidization conditions in an evolved porphyry copper system exhibiting several phases of copper and molybdenum mineralization and indications of hypogene enrichment.
