Copper Fox Announces Additional Drill Holes with Increased Soluble Copper Concentrations from Van Dyke Copper Deposit
Calgary, Alberta--(Newsfile Corp. - April 11, 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 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:
- DDH-OXY-10 returned an average of 0.748% ASCu over a 40.84m core interval including a 12.50m interval grading 2.253%ASCu.
- The four drill holes yielded increased weighted average ASCu concentrations of 16% compared to the original database.
- The four drill holes yielded an average 20% increase in the thickness of the mineralized intervals compared to the original database.
- The percentage ASCu/TCu is 30.7% higher in 2019 versus the original analytical results.
- The mineralized intervals in the four drill holes reported are open and additional sampling is required.
Elmer B. Stewart, President and CEO of Copper Fox, stated, "The results for 19 of the 23 drill holes that were re-analyzed yielded significant increases in the soluble copper concentrations over thicker mineralized intervals suggesting that the soluble copper content is higher and the dimensions of the deposit are larger than that used in the maiden resource estimate for the Van Dyke deposit completed in 2014. On receipt of the analytical results for the last four drill holes, the additional sampling required to close the mineralized intervals is planned."

TCu= total copper, (%) = percent, (m) = meters, ASCu = acid soluble copper, the above mineralized intervals do not represent true widths.
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 3 meters below cut-off within the mineralized interval was tolerated when estimating the weighted average.
Analytical Procedures:
Sample preparation and analytical work was 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 4 blanks and 7 certified reference standards were inserted (insertion rate 1:14) 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.
