Copper Fox Metals Inc. (“Copper Fox” or the “Company”) (TSX-V: CUU – OTC-Pink: CPFXF) and its wholly owned subsidiary, Desert Fox Copper Inc., are pleased to provide additional analytical results for the recently completed mapping and sampling program on its 100% owned Mineral Mountain copper project located approximately 15 miles east of Florence, Arizona.

Highlights:

  • A large area of copper-molybdenum mineralization has been located in the southeast corner of Area #1 with molybdenum concentration of up to 0.2%.
  • The copper mineralization in Area #1 and Area #3 has been extended and remains open in several directions.
  • The mineralization in Area #2 occurs within a narrow, northeast trending zone estimated to be 2.8 kms long.
  • Two new areas of significant copper mineralization have been located in the Laramide age intrusive.

Elmer B. Stewart, President and CEO of Copper Fox, stated, “Following the significant results from the initial sampling program, the recent results continue to expand the limits of the copper mineralization in Areas #1 and #3; and more importantly, has identified a large area of copper-molybdenum mineralization in the southeast corner of Area #1 along the Laramide/Precambrian intrusive contact. Results for the balance of the samples collected during the recently completed Phase 2 sampling program will be released on receipt thereof.”

Geological Model:

The surface mineralization represents weathered porphyry copper mineralization (a “leach cap”) sitting above a buried porphyry copper system (see news release dated April 30, 2018). The recent mapping program has located a number of intrusive phases in the Laramide age intrusive that are not shown on the preliminary geology map covering the project area. The sulfur content of the samples strongly supports the leached nature of the Laramide age intrusive that hosts the majority of the copper mineralization.

Analytical Results:

The mapping and sampling program consisted of mapping lithologies, alterations, and vein assemblages. Selected rock chip samples were collected from mineralized outcrops to characterize the metals present in veins, other mineralized structures and the outcrop. The samples are not necessarily representative of the mineralization on the property. Outcrop exposures within the sampled area are estimated to 5-10%. The approximate dimensions and average metal concentrations in the Areas sampled for the current analytical results are tabulated below (see tables below for individual sample results). Area #1:

The copper mineralization has been extended approximately 200m to the west and 400m to the south and southeast and remains open to the west and to the south towards Area #3. Sampling 1.6 kms to the east of Area #1 located a new area of copper mineralization hosted in the Laramide age Quartz Monzonite intrusive. The ground between Area #1 and the new discovery has been mapped and analytical results for the samples collected during this work are pending.

Area #3:

The copper mineralization has been extended approximately 400m to the south and mapping and prospecting indicates that the mineralization is open to the north toward Area #1 and to the south. A new area of copper mineralization has been located approximately 600m west of Area #3 hosted in Laramide age Quartz Monzonite intrusive. Analytical results for mineralized samples collected in Area #3.

Mineralization:

The copper mineralization occurs in quartz veins, veinlets and sheeted quartz veins (with and without potassic alteration envelopes), as malachite-chalcocite and chalcocite veins and veinlets (of variable thickness), on fractures and disseminations hosted in potassic and phyllic altered Laramide age Quartz Monzonite and porphyritic intrusives (containing 15-30% phenocrysts). The main copper minerals are malachite, chrysocolla and chalcocite with minor azurite, native copper and rare chalcopyrite. Gangue minerals include goethite after pyrite and jarosite.

Analytical and Sampling Procedures:

Outcrop sampling as well as mapping lithologies, alterations, and vein assemblages was completed. Selected rock chip samples were collected from outcrop to characterize the metals present in veins, other mineralized structures and the outcrop. Outcrop exposures within the sampled area are estimated to 5-10%. The samples were picked up from site by Skyline Laboratories of Tucson, Arizona.

Samples were crushed to plus 75% -10 mesh, split and pulverized to plus 95% -150 mesh. Pulps were subjected to a multi-acid digest (HNO3, HF, and HClO4). Gold was analyzed on a 30-gram charge by fire assay (FA-01) with an atomic absorption finish. Skyline’s package code TE-5 was used to analyze the samples for the base and other trace elements. Metal concentration in samples exceeding the upper limit of detection were assayed for copper using (MEA) and silver (FA-04). Skyline has an ISO/IEC 17025/2005 accreditation.

Quality Control:

A total of 1 field blank and 5 certified reference standards were inserted (insertion rate 1:17) with the sample for which analyses are being reported. QA/QC shows that the blank and standards were within +/-5% of accepted value for the blank and standards.

Elmer B. Stewart, MSc. P. Geol., President and CEO of Copper Fox, is the Company’s non-independent, nominated Qualified Person pursuant to National Instrument 43-101, Standards for Disclosure for Mineral Projects, and has reviewed and approves the scientific and technical information disclosed in this news release.
