Copper Fox Commences Updated Resource Estimate on the Van Dyke Copper Project
Calgary, July 17, 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 provide shareholders an update of activities and analytical results for the Van Dyke In-Situ Leach ("ISL") oxide copper project (see news release May 28, 2019).
Highlights:
- Moose Mountain Technical Services ("MMTS") has been retained to complete an updated resource estimate for the Van Dyke copper deposit.
- MMTS completed the Preliminary Economic Assessment of the Van Dyke copper deposit in 2015 and the maiden resource estimate in 2014.
- The four drill holes reported in this news release were previously reported to contain no soluble copper greater than 0.05%.
- DDH-UVD-14 returned an average of 0.445% acid soluble copper ("ASCu") over a 79.09 meter ('m') core interval including a 6.25m interval grading 1.008% ASCu.
- The additional sampling extended the mineralized intervals reported from the Phase I sampling program in six drill holes with increases ranging from 11.0m to 47.2m.
Elmer B. Stewart, President and CEO of Copper Fox, stated, "The analytical results from the Phase II sampling program along with a more robust geological model were the basis for the decision to proceed with an updated resource estimate. The updated estimate will include the drill holes listed in this news release along with five additional drill holes that were excluded from the maiden resource estimate for the Van Dyke copper deposit."
The weighted average acid soluble copper concentrations using a 0.05% ASCu cutoff for the last four drill holes from the Phase II analytical program reported in this news release are shown below. To compare the weighted average grades for the historical and 2019 analytical results, the analytical results from the historical database were weight averaged over the same interval corresponding to the 2019 interval.
DDH ID | Azi | Dip | From (m) | To (m) | Interval (m) | 2019 TCu (%) | Historical TCu (%) | 2019 ASCu (%) | Historical ASCu (%) | Acid Soluble 2019/Historical (%) |
OXY-21 | 0 | -90 | 457.81 | 498.35 | 40.54 | 0.397 | 0.412 | 0.121 | 0.025 | 484% |
UVD-14 | 0 | -90 | 521.06 | 600.15 | 79.09 | 0.425 | 0.264 | 0.445 | NR | |

TCu= total copper, (%) = percent, (m) = meters, ASCu = acid soluble copper, NR = reported no ASCu over 0.05%, the above mineralized intervals do not represent true widths.
The following table compares the thickness of the 2019 mineralized intervals based on 0.05% ASCu cut-off to the reported historical mineralized intervals for the four holes reported in this news release.
2019 Results | Historical Results | ||||||
DDH ID | From (m) | To (m) | Interval (m) | From (m) | To (m) | Interval (m) | Thickness (m) 2019 minus historical |
OXY-21 | 457.81 | 498.35 | 40.54 | NR | NR | 0.00 | 40.54 |
UVD-14 | 521.06 | 600.15 | 79.09 | NR | NR | 0.00 | 79.09 |
OXY-29 | 381.00 | 416.97 | 35.97 | NR | NR | 0.00 | 35.97 |
VD-10 | 312.75 | 395.63 | 82.88 | NR | NR | 0.00 | 82.88 |
NR = reported no ASCu over 0.05%, (m) = meters, the above mineralized intervals do not represent true widths.
The weighted average grades for the mineralized intervals were estimated using a 0.05% ASCu cutoff; in line with the cutoff grade used in the maiden resource estimate for the Van Dyke copper project completed in 2014. A maximum interval of 3 meters grading less than 0.05% ASCu within the mineralized interval was tolerated when estimating the weighted average. The Phase II sampling extended the mineralized intervals reported from the Phase I sampling in the follow drill holes. Re-stated weighed average grades and mineralized intervals are reported below.
Phase I Reported | Phase II Results | |||||||||
DDH ID | From (m) | To (m) | Interval (m) | 2019 TCu (%) | 2019 ASCu (%) | From (m) | To (m) | Interval (m) | 2019 TCu (%) | 2019 ASCu (%) |

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 15 blanks and certified reference standards were inserted (insertion rate 1:12) 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.
