Copper Fox Metals enlarges mineralized envelope at Van Dyke ISCR Project, Arizona
Copper Fox Metals Inc. [TSXV: CUU; OTCQX: CPFXF; FSE: HPU], through its wholly owned subsidiary Desert Fox Van Dyke Co., reported analytical results from the previously reported historical diamond drill core sampling program to further define the limits of the total soluble copper (TSCu) mineralization in certain drillholes on its 100%-owned Van Dyke in-situ copper recovery (ISCR) project located in the Globe-Miami Mining District, Gila County, Arizona.
Analytical results from eleven drillholes have been received, eight of which returned intervals exceeding the TSCu cutoff (0.025%) used in the mineral resource estimate (MRE) update completed in 2020. Analytical highlights include:
Highlights: DDH OXY-42, intersected a 100.59-metre core interval (336.19 to 436.78m) that averaged 0.250% total copper (TCu) and 0.163% TSCu.
DDH OXY-42 included a 22.86-metre core interval (337.72 to 360.58m) that averaged 0.481% TCu and 0.409% TSCu.
These analytical results have better defined the boundary between the Transitional and Sulphide mineral domains in the Van Dyke deposit.
Elmer B. Stewart, President and CEO of Copper Fox, stated, “The sampling program has better defined the total soluble copper envelope in certain portions of the Van Dyke copper deposit. With eight of the eleven drill holes yielding analytical results above the 0.025% TSCu cutoff used in the 2020 MRE, the combination of these results and the pending analytical results from an additional eighteen drillholes suggests the potential to increase the TSCu content of the Van Dyke deposit.”
Analytical results for eight historical diamond drillholes from the Van Dyke project are reported in this news release. Analytical results from an additional 18 drillholes are pending. The analytical results of economic interest are acid soluble copper (ASCu) and cyanide soluble copper (CNCu). The TSCu (acid + cyanide soluble copper) cutoff grade used in the 2020 MRE was 0.025%.
The weighted average grades for the mineralized intervals presented in Table-1 used a 0.025% TSCu cutoff and a maximum core interval of five (5) meters of material below cut-off and/or missing samples within the mineralized interval in line with the cutoff grade used in the 2020 MRE.
The 2026 sampling completed in DDH OXY-42 extended the TSCu mineralization from 336.19-436.78 metres, an additional 100.59 metres down dip. The TSCu envelope in this drill hole now extends from a core interval of 249.33 metres to 436.78 metres. The objective of the sampling program was to either fill data gaps identified in previous sampling programs or extend the limits of the TSCu envelope to better define the boundary between the Transitional and Sulphide copper domains within the Van Dyke deposit. Analytical results for three drill holes yielded below cutoff (0.025% TSCu) copper concentrations.
Copper Fox and its subsidiaries own 100% of the Van Dyke ISCR project, a development stage, potential near term, mid-size copper mine in Arizona and a 25% interest in the Schaft Creek Joint Venture with Teck Resources Limited (75% interest and Operator) which hosts the Schaft Creek copper-gold-molybdenum-silver project in British Columbia’s Golden Triangle.
In addition, Copper Fox owns 100% of the resource stage Eaglehead polymetallic porphyry copper project in northwestern British Columbia and the Sombrero Butte and Mineral Mountain advanced exploration stage porphyry copper projects located in the prolific Laramide age copper province in Arizona.
