Calgary, Alberta--(Newsfile Corp. - June 1, 2023) - Copper Fox Metals Inc. (TSXV: CUU) (OTCQX: CPFXF) ("Copper Fox" or the "Company") and its wholly owned subsidiary, Desert Fox Copper Inc. ("Desert Fox"), are pleased to provide the results of ongoing compilation of recently acquired data in advance of the planned geophysical survey on its 100% owned Mineral Mountain project located approximately 25 kilometers (15 miles) east of Florence, Arizona. (See News Release dated April 19, 2023). The survey is expected to commence before the end of June subject to the arrival of the geophysical crew. Highlights of the compilation are set out below:
Highlights
- The modelling of analytical data outlined overlapping, northeast trending zones of greater than 1,000 parts per million ("ppm") copper and greater than 30 ppm molybdenum.
- The copper zone measures approximately 3,000 meters ("m") by 700 m, and the molybdenum zone measures approximately 2,800 m by 600 m. These zones exhibit a strong spatial correlation to the chargeability signature identified in 2021.
- Whole rock geochemistry has outlined two distinct rock suites: a granodiorite-quartz diorite suite and a quartz monzonite suite.
- The recent sampling returned significant copper mineralization ranging from 1,620 to 27,200 ppm in granodiorite, quartz diorite and quartz monzonite intrusive phases of the Mineral Mountain intrusive.
- A new wholly owned subsidiary of Copper Fox named Desert Fox Mineral Mountain Co. has been formed for legal and accounting purposes.
Elmer B. Stewart, President, and CEO of Copper Fox, stated, "The compilation and modelling indicates the Mineral Mountain intrusive is more complex than previously thought. Whole rock geochemistry utilizing alkali/silica diagrams indicates proximal alkalic and sub-alkalic intrusive phases containing significantly different copper concentrations suggesting multiple mineralized intrusive phases from an interpreted "cupola" underlying the project consistent with the modelling of the 2022 airborne magnetic survey data."
Geological Model
The copper footprint exposed at Mineral Mountain is interpreted to represent the oxidized surface expression of a gold-molybdenum rich porphyry copper system similar to other porphyry copper deposits in the Safford Mining District in Arizona.
The oxidized/supergene process transformed the primary copper mineralization (chalcopyrite-chalcocite) to secondary copper minerals; specifically, malachite, chrysocolla and chalcocite and the magnetite to hematite. The mineralization is hosted in a porphyritic Laramide age intrusive (69.7 +/- 0.4 Ma; U/Pb zircon) associated with strong potassic alteration (Kspar-biotite-magnetite) contained within a broader zone of sericitic-chlorite alteration.
Compilation
Modelling
Modelling of the copper and molybdenum concentrations were completed using thresholds of 1,000 ppm for copper and 30 ppm for molybdenum. The locations, dimensions and general outline of the copper and molybdenum modelled shapes exhibit a strong correlation. The molybdenum mineralization overlaps and extends to the west of the copper shape (see Image #1).
Inflection points in the overlapping copper, molybdenum and 2021 chargeability signatures indicate post-mineralization structural re-adjustment (dextral movement) marked by a strong N trending late-stage dike swarm. The late-stage dike swarm is interpreted to have been emplaced along an interpreted N trending fault zone.

Copper Mineralization
Sampling of selected outcrop along the proposed geophysical survey lines was completed for whole rock geochemical and petrographic studies to determine the chemical composition and obtain detailed description of the mineralogy/alteration of the samples. Of the 13 samples collected, one sample contained chalcopyrite, nine samples exhibited evidence of leaching and a combination of quartz vein, fracture and disseminated styles of copper mineralization. Six of the samples of granodiorite, quartz diorite and quartz monzonite composition returned copper concentrations ranging from 0.16% up to 2.72%, with the highest copper concentration (0.67% and 2.72%) contained within the quartz monzonite samples. The results of the petrographic study on these samples are pending.
Whole Rock Geochemistry
Whole rock geochemical studies based on alkali/silica ratio indicates two distinct populations of intrusive rocks. The majority of the samples are sub-alkaline and plot within in the granodiorite/quartz diorite fields. The second population are alkalic in nature and plot in the quartz monzonite/monzonite field. The clustering of the sample locations on the alkali/silica diagram suggests two very distinct intrusive phases.
QA/QC
The copper and molybdenum shapes were generated using the implicit modelling application contained within the Micromine software package. Whole rock analyses were completed by Actlabs (ISO/IEC 17025:2017; ISO 9001:2015) located in Ancastor, Ontario using their 4LITHO (11+) QOP WRA/ QOP WRA 4B2 (/Major/Trace Elements Fusion ICPOES/ICPMS) package. Whole rock classifications utilized the Total Alkalis vs Silica IUGS classification system for intrusive rocks.
