COPPER FOX ANNOUNCES PORPHYRY COPPER DISCOVERY AND STRONG VECTORS TOWARD CORE AT MINERAL MOUNTAIN

Copper Fox Metals Inc. and its wholly owned subsidiary, Desert Fox Mineral Mountain Co., has released preliminary results from diamond drill hole (DDH) MM-02-2025 at its 100-per-cent-owned Mineral Mountain porphyry copper project in Arizona. DDH MM-02-2025 has confirmed the presence of a large, evolved porphyry copper-molybdenum system and intersected the outer portion of a mineralized copper shell, with multiple geological indicators suggesting increasing mineralization at depth and proximity to the core of the system. DDH MM-01-2025 intersected the shoulder of the system approximately 1.3 kilometres southwest of DDH MM-02-2025.

Elmer B. Stewart, president and chief executive officer of Copper Fox, stated: "DDH MM-02-2025 intersected a classic porphyry alteration and mineralization sequence and indicates vectoring toward a potential higher-grade potassic core below that marks an important advance in our understanding of the Mineral Mountain porphyry copper system. The distribution and increase in copper-molybdenum mineralization, quartz veining, high-temperature alteration minerals, magnetite sulphidization and appearance of bornite rimming chalcopyrite at depth indicate that drilling has not yet reached the core of this large porphyry system. Intersecting the outer, lower-grade part of the copper shell, together with increased molybdenum values, provides clear targets for follow-up drilling and supports our view that higher-grade mineralization may lie below the current drill depth."

Highlights:

• Porphyry copper system confirmed, with multiphase alteration and mineralization;
• DDH MM-02-2025 intersected the outer copper shell, with grades increasing downhole;
• Strong vectoring indicators toward a higher-grade core at depth;
• Significant quartz-sulphide veining and sulphide content increase with depth;
• Copper-molybdenum mineralization hosted in quartz veins, fractures and disseminations in vein alteration envelopes;
• DDH MM-02-2025 terminated early at 1,697.35 metres due to drilling conditions, leaving system open at depth;
• Located six mineral claims to cover extension of recently identified porphyry copper target.

The Mineral Mountain project is located in a prolific Laramide-age porphyry copper belt in Arizona, approximately 25 kilometres southwest of Rio Tinto and BHP's giant Resolution porphyry copper-molybdenum deposit and approximately 20 kilometres northeast of the recently commissioned Florence ISCR (in situ copper recovery) copper mine reinforces the porphyry potential of the property.

DDH MM-02-2025 can be re-entered to deepen the drill hole to test the core of the porphyry system below 1,700 metres and used for stepout drilling to define the lateral extent of the copper shell.

Lithologies

DDH MM-02-2025 intersected a fine-grained granodiorite from surface to a depth of 380.09 metres and Precambrian Pinal Schist from 380.09 metres to the end of the hole at 1,697.35 metres. These lithologies are intruded by a series of synchronous and postmineralization rhyolite porphyry, quartz monzonite porphyry and quartz latite porphyry dikes of variable thickness.

Alteration

DDH MM-02-2025 intersected early potassic (hydrothermal biotite, anhydrite, magnetite veins and potassium-spar envelopes) overprinted by propylitic (epidote/chlorite/actinolite) followed by strong phyllic ((quartz/sericite/pyrite, or QSP) and locally late intermediate argillic (fresh potassium-spar and plagioclase altered to sericite) like that observed in porphyry copper systems. Beginning at approximately 600 metres below surface, the drill hole intersected propylitic altered Pinal Schist to a depth of approximately 1,140 metres. The QSP alteration (1,140 to 1697.35 metres) shows increasing pyrite content (up to 3 per cent), coarse-grained sericite and quartz veining (up to 41 per cent) and obliterates the original fabric of the Pinal Schist associated with increasing molybdenite and trace bornite concentrations toward the end of the hole. The localized late-stage intermediate argillic alteration is associated with a weakly mineralized quartz-eye quartz monzonite porphyry. The drill hole is interpreted to have penetrated the outer portion of the copper shell and indicates vectoring toward an expected higher-grade potassic core typically seen in porphyry systems.

Analytical results

Sampling of DDH MM-02-2025 began at a core depth of 896 metres within propylitic altered Pinal Schist, characterized by crackle texture, chlorite-epidote alteration envelopes, scattered thin veinlets of vuggy potassium-spar/quartz/chlorite/epidote/pyrite/chalcopyrite/scheelite and thin red-fluorescent calcite veinlets. Analytical results for the sampling between 896 metres and 1,394 metres have been received and returned the following metal concentrations: copper -- from 12.9 to 2,032 parts per million (0.203 per cent), molybdenum -- from 1.0 to 515 parts per million (0.051 per cent) and silver -- from 0.1 to 4.5 parts per million. The analytical results show an increasing trend in copper-molybdenum values at depth associated with strong phyllic alteration and quartz-chalcopyrite-plus-or-minus-molybdenite veining.

The core interval 1,365 to 1,394 metres exhibits intense quartz/sericite/pyrite alteration and elevated copper (58.9 to 2,032 parts per million (0.203 per cent), molybdenum 22.0 to 515.0 parts per million (0.051 per cent) and 0.1 to 0.9 part per million silver values. Upon receipt of all analytical results, selected samples containing elevated copper content will be analyzed for gold concentration.

Mineral zonation

DDH MM-02-2025 exhibits progressively higher-temperature sulphide mineralization and associated alteration at increasing depth in the hole. The outer portion of the porphyry system is characterized by propylitic alteration containing variable concentrations of pyrite in the core interval 600 to 1,140 metres below surface. The pyrite shell is interpreted to have been intersected at an estimated depth of 1,140 metres associated with the transition to QSP alteration.

The increase in copper content in DDH MM-02-2025 exhibits a crude correlation to transition from propylitic to QSP alteration. Typically, the outer copper-enriched pyritic portion of a porphyry system contains low copper content in the order of 0.10 per cent to 0.20 per cent. The central potassic core of a porphyry system at depth is typically enriched in bornite and chalcopyrite.

The increase in molybdenum concentrations in DDH MM-02-2025 shows a moderate correlation to the QSP/outer potassic zone. Porphyry copper systems typically exhibit a broad, annular molybdenum halo that extends outward and upward from the higher copper concentrations typically observed in the inner potassic zone.

Vein assemblages

The sulphide veins intersected in DDH MM-02-2025 displays with depth, the transition from the outer lower-temperature propylitic (quartz/calcite/hematite veining) to the inner higher-temperature potassic alteration overprinted by intense QSP alteration. The outer portion of the system exhibits abundant classic D veins (quartz/pyrite plus or minus chalcopyrite with distinct QSP envelopes). Chalcopyrite is the main copper sulphide with molybdenite and trace amounts of bornite appearing in the lower portions of the drill hole. The copper-molybdenum mineralization occurs primarily in quartz veins with subordinate amounts occurring on fractures and as disseminations in quartz vein alteration envelopes. The crosscutting relationships of the veins indicate several episodes of mineralization and alteration.

Drilling and sampling procedures

The upper 517-metre portion of DDH-02-2025 was completed using HQ rods before reducing to NQ-diameter rods. Overall core recovery was estimated to be greater than 95 per cent. After cutting with a diamond saw, one-half of the core was collected for sample preparation and analysis, and the other half was retained on site for future reference. Sample intervals selected do not cross lithological boundaries and ranged from 1.00 to 3.00 metres in length depending on the presence of copper and/or molybdenum mineralization.

Quality assurance/quality control

Copper Fox follows a rigorous QA/QC program. A total of 352 core samples were submitted as part of the drill core analysis, including 11 split-core duplicates, 30 commercial certified reference material (CRM) standards and 34 blanks. The matrix material of the CRMs matches the Mineral Mountain geology. All standards are certified for four-acid digestion.

Skyline Assayers and Laboratories Inc. (Accreditation 2953.01 and Standard ISO/IEC 17025:2017) located in Tucson, Ariz., completed the sample preparation and analysis for the Mineral Mountain samples. Samples were prepared using preparation code SP-1 -- crush to plus 75 per cent minus-10 mesh, split and pulverize with standard steel to plus 95 per cent minus-150 mesh. Analytical code TE-7 was used for trace elements by multiacid (with hydrofluoric acid); silver, arsenic, mercury, antimony, selenium and tellurium concentrations were determined by aqua regia and ICP-OES/ICP-MS (49 elements).
