5/5, 12:00 PM (Source: Newsfile Corp)

Calgary, Alberta--(Newsfile Corp. - May 5, 2020) -  Copper Fox Metals Inc. ("Copper Fox" or the "Company") (TSXV: CUU) (OTC Pink: CPFXF) and its wholly owned subsidiary, Desert Fox Van Dyke Co., are pleased to report that it has filed on SEDAR a National Instrument 43-101 ("NI 43-101") Technical Report (the "Technical Report") which includes an updated resource estimation for the Van Dyke copper project located in the Globe-Miami mining district of Arizona.

The Technical Report is titled "Technical Report and Updated Resource Estimate for the Van Dyke Copper Project" dated May 4, 2020 and was prepared by Moose Mountain Technical Services ("MMTS"). The effective date of the Technical Report is January 9, 2020 and the resource estimate was disclosed in a news release dated March 25, 2020. Highlights are:

Highlights:

  1. The exploration potential for additional resources is extensive to the south and at depth.
  2. Metallurgical testwork indicates that the deposit is amenable to recovery using in-situ leaching (ISL) with an estimated metallurgical recovery of 90%.
  3. Recommendations include a combined eight-hole (4,500m) drilling, metallurgical, geotechnical and hydrogeological program estimated to cost US$2.13 million.
  4. Additional engineering studies to update the PEA.

Elmer B. Stewart, President and CEO of Copper Fox stated, "The 2019 work has significantly changed the understanding of the origin and mineral potential of the Van Dyke project. The highlighted results of the updated resource estimate include: 1) an upgrade of a portion of the resource to the Indicated category; 2) an overall 50% increase in soluble copper content; and 3) a potentially 2km long extension of the Van Dyke deposit to the southwest. The Technical Report recommends a drilling program and additional engineering studies which highlights the exploration potential to add value by expanding the limits of the Van Dyke project."

The updated Resource Estimate for the Van Dyke project is summarized in the table below (see news release dated March 25, 2020 for details):

Resource Estimate for the Van Dyke Deposit, effective date January 9, 2020:




Cu Metal (Mlbs)
ClassKTonnes (000)Rec Cu (%)TCu (%)ASCu (%)CNCu (%)Recovery (%)Soluble CuTotal Cu
Indicated97,6370.240.330.230.0490517717
Inferred168,0260.190.270.170.04906991,007

 

M(lbs)=millions of pounds, (%)=percent, ASCu=acid soluble copper, CNCu=cyanide soluble copper, Rec Cu(%)=estimated recoverable copper grade, Soluble Cu=sum of ASCu + CNCu, Total Cu=total copper

Notes for Table:

  1. The "reasonable prospects for eventual economic extraction" shape has been created based on a copper price of US$2.80/lb, employment of in-situ leach extraction methods, processing costs of US$0.60/lb copper, and all in operating and sustaining costs of $US1.25/tonne, a recovery of 90% for total soluble copper and an average Specific Gravity of 2.6t/m3.
  2. Approximate drill-hole spacings is 80m for Indicated Mineral Resources
  3. The average dip of the deposit within the Indicated and Inferred Mineral Resource outlines is 20 degrees. Vertical thickness of the mineralized envelope ranges from 40m to over 200m.
  4. Numbers may not add due to rounding.

Cautionary Note to Investors:
While the terms "measured (mineral) resource", "indicated (mineral) resource" and "inferred (mineral) resource" are recognized and required by National Instrument 43-101 - Standards of Disclosure for Mineral Projects, investors are cautioned that except for that portion of mineral resources classified as mineral reserves, mineral resources do not have demonstrated economic viability. Investors are cautioned not to assume that all or any part of measured or indicated mineral resources will ever be upgraded into mineral reserves. Additionally, investors are cautioned that inferred mineral resources have a high degree of uncertainty as to their existence, as to whether they can be economically or legally mined, or will ever be upgraded to a higher category.

Investors are advised that current Mineral Resources are not current Mineral Reserves and do not have demonstrated economic viability.

Recommended Exploration Program:
The recommended program is estimated to cost $US2.13 million; the main components of which are outlined below:

  1. Diamond Drilling & Analysis: an 8-hole (4,500m) program to test the extension of the Van Dyke deposit to the southwest and collect whole core samples for additional metallurgical testwork.
  2. Down-Hole Geophysics: Downhole acoustic televiewer survey to collect geotechnical data on rock mass characteristics such as fracture orientations and density.
  3. Metallurgical Testwork: 6-8 pressure leach tests on whole core from select areas of the deposit to obtain additional data on copper recoveries, leach time, reagent consumption and solution chemistry.
  4. Hydrogeology: Installation of piezometers to obtain additional data on water level fluctuations and sampling points for ground water geochemical analyses.

Recommendations for Ongoing Engineering Studies:
Recommendations for ongoing engineering studies include: run a pilot ISL test; update the Cost Estimate, Geotechnical and Water Management Studies; and then revise the Van Dyke ISL PEA project dated December 18, 2015 using the updated resource estimate. The estimated cost for this work is $US10 million.

Exploration Potential:
Updating the geological model for the Van Dyke deposit included the review and compilation of all available historical geological, geophysical and drilling reports on work completed on the Van Dyke project since the late 1960s. In 1970, Occidental Minerals identified the Azurite target approximately 2km south of the Van Dyke deposit.

The review completed in 2019 did not locate any reports on activities completed on the Azurite target, however, several maps showing the results of an Induced Potential survey and exploration activities for this target were reviewed. Historical exploration activities include:

  1. three drill holes;
  2. several long surface trenches; and
  3. nine outcrops containing secondary (azurite) copper mineralization.

The updated resource estimate combined with historical exploration results suggests that the area of the project extending from the southwest edge of the Van Dyke deposit to the Azurite target is a high priority exploration target, see map below:
