Copper Fox Identifies Drill Target at Mineral Mountain Project
CALGARY, Alberta, May 29, 2018 (GLOBE NEWSWIRE) – Copper Fox Metals Inc. (“Copper Fox” or the “Company”) (TSX-V:CUU) (OTC:CPFXF) is pleased to provide analytical results for the remaining 12 re-sampled trenches on its 100% owned Mineral Mountain copper project located near Florence, Arizona (see news release dated April 30, 2018). Highlights from the sampling program are:
Highlights:
- A drill target measuring about 600m by 500m has been defined based on work to date.
- Incomplete oxidization has yielded a number of previously unknown mineralized intervals with copper ranging from 1,000 ppm (0.1%) to 3,890 ppm (0.39%) and molybdenum ranging from 72 ppm (0.007%) to 209 ppm (0.02%) as well as elevated concentrations of gold.
- The Laramide age intrusive is characterized by highly anomalous concentrations of copper-molybdenum-gold and silver over a minimum area of 600m by 500m.
- The mineralized zone (2016 and 2018 sampling) is located within a three kms wide, north-south trending zone of intense structural deformation.
- The mineralized zone shows a generally concentric pattern with the higher copper-molybdenum concentration in the center.
Elmer B. Stewart, President and CEO of Copper Fox, stated, “Copper Fox is pleased that the trenching results support the presence of a buried porphyry system on the Mineral Mountain project. Identifying a drill target in the early stages of exploration is very encouraging. Copper Fox is currently evaluating the possibility of drill testing this target to determine the depth and grade of the interpreted porphyry that provided the source of the Cu-Mo-Au-Ag mineralization exposed at surface.”
Geological Model:
The geological model for the project suggests that the surface mineralization resulted from mineralized fluids that leaked upward through fractured Laramide age granodiorite from a deeper, geochemically zoned buried porphyry copper system. Such leaks are clearly manifested as steeply dipping, copper-molybdenum bearing veins and aplite dikelets that exhibit a broad range of strike orientations and support the interpretation that significant post-mineral rotation of the district has not occurred since the time of the Laramide mineralization.
Factor analysis (geochemical vectoring) of the 2018 geochemical data has identified early Cu-Mo-Au-Ag, late stage As-Sb-W and relict supergene/oxidization S-In-U geochemical factors related to porphyry-type copper mineralization. The geochemical association Pb-Zn-Cd normally found as a halo surrounding Cu-Mo-Au-Ag mineralization is probably present beyond the limits of the trench area.
Summary of 2018 Sampling Results:
The weighted average metal concentrations for the trenches located within the mineralized area are outlined below.
Trench | Interval | Copper | Molybdenum | Gold | Silver | Comments |
ID | (m) | (ppm) | (ppm) | (ppb) | (ppm) | |
E | 23.4 | 534 | 1.9 | 22 | 0.83 | includes one 3.0m sample containing 1,430 ppm (0.14%) Cu |
F | 9 | 52 | 0.6 | 5 | 0.37 | |
G | 45 | 341 | 3.1 | 5 | 1.51 | includes one 3.0m sample containing 1,330 ppm (0.13%) Cu, |
H | 29.8 | 146 | 1.1 | 5 | 0.39 | |
N | 67.5 | 610 | 19.4 | 8 | 2.3 | includes three, 3.0m samples with 2,550 ppm (0.25%), |
3,110 ppm (0.31%) and 1,020 ppm (0.10%) | ||||||
Note: ppm = parts per million, ppb = parts per billion |
Trenches A, I, J, P, Q, R, S, and T are located outside the mineralized zone and returned low concentrations of copper, molybdenum, gold and silver as expected.
The 2018 re-sampling located a number of previously unknown intervals of higher copper-molybdenum concentrations in addition to the 2016 sampling results. For example, Trench D returned 0.38% copper and over 12.0m with the mineralized interval being open to the east (see news release dated April 30, 2018), and the mineralized interval in Trench N (see above table), as well as the higher molybdenum values present in trenches D (72 ppm (0.007% over 12 m), O (two 3.0 m samples containing 103 ppm (0.01%) and 109 ppm (0.01%)), C, and M. Elevated gold concentrations occur sporadically with the higher copper concentrations.
Metal Content by Lithology:
The trenches were excavated in Laramide age granodiorite (170 samples), Pinal Schist (6 samples), and PreCambrian granite (57 samples). The AVERAGE metal concentration for the lithologies are listed below:
Lithology | Cu (ppm) | Mo (ppm) | Au (ppb) | Ag (ppm) |
Pinal Schist | 20 | 0.48 | 5 | 0.22 |
Granodiorite | 438 | 10 | 15.3 | 1.03 |
PreCambrian Granite | 60 | 2.3 | 7.3 | 0.26 |
The MEDIAN metal concentrations of for the various lithologies are listed below:
Lithology | Cu (ppm) | Mo (ppm) | Au (ppb) | Ag (ppm) |
Pinal Schist | 52 | 0.48 | 5 | 0.22 |
Granodiorite | 188 | 2.2 | 9 | 0.5 |
PreCambrian Granite | 52 | 1.9 | 6 | 0.2 |
Sampling Procedures:
Continuous sampling was completed either along the side of the trench or along the center line on the bottom of the trench. Samples (approximately 2 kgs in weight) were collected after the top layer of material was removed. The sample interval was maintained at 3 meters except where sample breaks were necessary. Detailed mapping of lithology, alteration and vein assemblages was completed for all trenches. The samples (233 in total) were delivered by the consulting geologist to Skyline Laboratories in 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, HClO4) followed by analysis by ICP/OES. Gold was analyzed on a 30-gram charge by fire assay with an atomic absorption finish. Skyline’s package code TE-5 was used to analyze the samples for the base and other trace elements. Skyline has an ISO/IEC 17025/2005 accreditation.
Quality Control:
The first sample of each batch was a field blank. One certified standard pulp was inserted into the sample stream for each laboratory batch of twenty samples. A total of 3 field blank and 12 certified reference standards were inserted with the sample batches for which analyses have been received. All standards were within +/-5% of accepted value for the standards.
