Copper Fox Reports Final Analytical Results From Phase 2 Sampling Program at Mineral Mountain
CALGARY, Alberta, Dec. 19, 2018 (GLOBE NEWSWIRE) – 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 the final 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:
- Copper mineralization has been traced in outcrop over a horizontal distance of 4,500m by up to 2,000m wide.
- Within the copper mineralized area, two large areas of coincident molybdenum mineralization have been outlined.
- Sampling in Area 1 has returned copper concentrations of up to 10.38% copper and 0.015% molybdenum hosted in Laramide age Quartz Monzonite.
- Sampling in Area 3 has returned copper concentrations of up to 9.52% copper and 0.022% molybdenum hosted in Laramide age Quartz Monzonite.
- The high copper grades in samples are due to abundant chalcocite.
Elmer B. Stewart, President and CEO of Copper Fox, stated, “The sampling program has partially outlined a large Laramide age porphyry copper system at Mineral Mountain. The secondary copper minerals and trace element geochemistry combined with abundant mineralized outcrop containing chalcocite support the presence of a Leach Cap; a feature typically located above porphyry deposits in arid and semi-arid climates. The occurrence of disseminated, fracture and quartz vein hosted copper mineralization, abundance of chalcocite, coincident copper-molybdenum mineralization and mineralized porphyritic intrusive phases suggest that at the current level of erosion, the interpreted sulphide copper-molybdenum portion of the porphyry system is closer to surface than previously interpreted. Compilation of the data is underway, the results of which will be used to determine the exploration activities required to advance the project to the drill stage.”
Geological Model:
The secondary copper minerals, trace element geochemistry and abundance of chalcocite at Mineral Mountain represents the weathered surface of porphyry copper style mineralization (a “Leach Cap”). Porphyry copper deposits in climates like Arizona typically exhibit a Leach Cap on surface, underlain by high grade copper mineralization referred to as a “chalcocite blanket”, due to supergene enrichment followed by sulphide copper mineralization at depth. Copper and molybdenum are the primary metals in Laramide age porphyry deposits in Arizona.
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 and trace element geochemistry present in veins, other mineralized structures and the outcrop. The samples are not necessarily representative of the mineralization on the property. Non-mineralized outcrops were also sampled to determine background concentration of various elements. Outcrop exposures within the areas sampled during this phase of the program are estimated to range between 2-5%. The average metal concentrations for the new analytical results are tabulated below and do not include previously announced results discussed in the November 21, and November 29, 2018 news releases (see tables below for individual sample results).

Mineralization:
The copper mineralization occurs in quartz veins, veinlets and sheeted quartz veins as malachite-chalcocite and chalcocite veins and veinlets (of variable thickness), on fractures and as disseminations 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 styles of mineralization were completed. Selected rock chip samples were collected from outcrop to characterize the base metals and trace element geochemistry present in veins, other mineralized structures and outcrops. Outcrop exposures within the areas sampled during the last phase of the program are estimated to be between 2-5%. 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 certified blank and 4 certified reference standards were inserted (insertion rate 1:15) 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.
