Copper Fox Announces Additional Significant Increases in Soluble Copper Concentrations from Van Dyke Copper Deposit
February 28, 2019
Calgary, Alberta–(Newsfile Corp. - February 28, 2019) - Copper Fox Metals Inc. (TSXV: CUU) (OTC Pink: CPFXF) (“Copper Fox” or the “Company”) and its wholly owned subsidiary, Desert Fox Copper Inc. (“Desert Fox”), are pleased to announce additional analytical results from the recently announced program on the Van Dyke oxide copper deposit (see news release January 23, 2019). Van Dyke is an In-Situ Leach (“ISL”) project where the commodity of interest is acid soluble copper (“ASCu”).
Highlights are:
- DDH-UVD-13 returned an average of 0.616% ASCu over a 93.84m core interval.
- The 2019 result for DDH-UVD-13 represent a 73% increase in ASCu content and a 51% increase in thickness of the mineralized interval.
- DDH-UVD-12 returned a combined mineralized interval of 102.47m versus 63.71m reported in the original data base, a 61% increase in thickness.
- The four drill holes show increases in weighted average ASCu concentration that range from 5 to 73% higher than in the original data base.
- The mineralized intervals in two of the drill holes are open and additional sampling is required to determine the length of these mineralized intervals.
Elmer B. Stewart, President and CEO of Copper Fox, stated, “The objective of the 2019 analytical program is to determine the dimensions and increase the confidence level of the acid soluble copper concentrations in the Van Dyke oxide copper deposit. The 2019 results received to date continue to yield higher acid soluble copper concentrations and thicker mineralized intervals. The 2019 results are encouraging and suggest that the dimensions of the Van Dyke deposit are larger than previously modelled.”
The weighted average acid soluble copper concentrations for the 2019 results compared to the original results are:

TCu= total copper, (%) = percent, (m) = meters, ASCu = acid soluble copper, the above mineralized intervals do not represent true widths.
Total Copper (TCu) concentrations reported in the original project data base correlates with the 2019 results whereas significant variation has been identified between the original soluble copper concentration and the 2019 results at the sample and drill hole level.
The weighted average grades for the mineralized intervals were estimated using a 0.05% copper cutoff, in line with the cutoff grade used in the maiden resource estimate for the Van Dyke project completed in 2014. A maximum interval of 3m below cut-off within the mineralized interval was tolerated when estimating the weighted average.
Analytical Procedures:
Sample preparation and analytical work were completed by Skyline Assayers & Laboratories located in Tucson, Arizona. Skyline’s package codes CuT, CuSeq and CuCn were used to determine total copper, sequential copper and cyanide soluble copper. The sequential copper analysis uses a 0.25 gram sample digested (at room temperature) in 5% sulfuric acid and the solution is then diluted to 100 mL with deionized water. The residue from the sample is digested in 10% sodium cyanide solution and diluted to 100 mL. Atomic Absorption Spectrometry (“AAS”) was used to determine copper concentrations. Skyline has an ISO/IEC 17025/2005 accreditation.
Quality Control:
A total of 3 field blank and 7 certified reference standards were inserted (insertion rate 1:12) 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.
