Copper Fox Announces Final Analytical Results from Re-Sampling Program at Van Dyke Copper Deposit
Calgary, Alberta–(Newsfile Corp. - May 7, 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 the final results for the re-analytical 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:
- DDH-OXY-18 returned an average of 0.284% ASCu over a 199.95m core interval including a 21.03m interval grading 1.141% ASCu.
- DDH-OXY-5 returned an average of 0.510% ASCu over a 33.53m interval including 0.931% ASCu over 13.71m and an average of 0.350% ASCu over a core interval of 57.91m including 1.046% ASCu over 10.67m.
- 20 of the 25 drill holes re-analyzed returned higher (3 to 260%) ASCu concentrations and 19 drill holes returned thicker (1.0 to 62.7m) mineralized intervals when compared to the original data base.
- The ASCu/TCu ratio for all samples analyzed averaged 86% in 2019 compared to 71% in the original data base.
Elmer B. Stewart, President and CEO of Copper Fox, stated, “The increased ASCu/TCu ratio combined with the higher ASCu concentrations and thicker mineralized intervals are encouraging. The full impact of these factors will only be known when additional sampling has been completed. Updating of the geological model for the Van Dyke deposit is underway and the additional sampling required to define the full extent (thickness) of the mineralized intervals is expected to commence immediately. Contingent on the results of these activities, Copper Fox may assess the possibility of completing an updated resource estimate for the project.”

In DDH VD-5, the interval from 450.80 to 524.56 was not re-sampled with the interval containing original results of TCu concentrations that range from 0.018% to 0.151%. In DDH VD-16, the interval from 572.11 to 612.54 was sampled and returned ASCu concentrations below the 0.05% cutoff.
The re-analysis program consists of 25 drill holes. The results of the 2019 program compared to the original project data base is summarized as follows: 20 drill holes returned higher (from 3 to 260%) ASCu concentrations, four drill holes returned lower (15 to 76%) ASCu concentrations and one drill hole returned the same ASCu concentration. 19 drill holes returned thicker (from 1.0 to 62.7m) mineralized intervals, two drill holes returned thinner (8.0m and 16m) mineralized intervals and the mineralized interval in four drill holes remained unchanged.

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 3m below the 0.05% ASCu 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. 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 5 blanks and 18 certified reference standards were inserted (insertion rate 1:11) with the samples for which analyses are being reported. The Skyline results for the blank and standards were within +/-5% of accepted value for the blank and standards.
