Projects

Overview

Northern Fox Copper Inc., a wholly owned subsidiary of Copper Fox Metals Inc., owns 24.4% of the issued and outstanding shares of District Copper Corp. (formerly Carmax Mining Corp.). in late 2018, District opted to engage in gold exploration and completed the acquisition of a 100% working interest in the Stony Lake gold project located in central Newfoundland on February 8, 2019.  District also holds a 100% working interest in the Eaglehead copper-gold-molybdenum-silver located in northern British Columbia.

Stony Lake Project:

The Stony Lake gold project (13,025 ha) project covers a 27 km strike length of the Cape Ray/Valentine Lake structural trend in central Newfoundland, Canada’s newest emerging orogenic gold district.  This district hosts several recent high-grade gold discoveries including Sokoman Iron Corporation’s Moosehead discovery, Antler Gold’s Twilight zone and Marathon’s Valentine Lake gold deposit.  The Stoney Lake project is located between the Moosehead discovery to the northeast and the Twilight zone to the southwest.

The 2019 Stony Lake program consists of mapping, prospecting and sampling and a property wide airborne magnetometer and radiometric survey to map bedrock lithologies, structural features and zones of potassic alteration.  The 2019 program commenced in early May on the Rabbit Tracks and Frenchman’s Pond targets where preliminary results have been encouraging.  Analytical results are pending.

The Rabbit Tracks target is underlain by extensive quartz-feldspar porphyry intrusive with disseminated pyrite and arsenopyrite; several, altered, weakly mineralized mafic dikes and a coarse-grained crystal tuff unit within fine grained sandstones and siltstones of the Wigwam Formation.  Two large areas of silica, (quartz veining, stockworks) sericite and carbonate altered sub-crop and angular boulders carrying 1% to 3% disseminated pyrite/arsenopyrite extending over a horizonal distance of between 600 to 1,000 meters have been identified.

At the Frenchman’s Pond target, a zone (1,000m by 75m) of silicified and sericite altered fine grained sandstone containing 2% to 5% pyrite has been located.  In 2008, several grab samples from angular boulders located approximately 1 km north of Frenchman’s Pond assayed from 2.9 to 3.4 g/t gold.

District continues to expand the size of its Stony Lake project and has entered into separate arm’s length agreements to acquire, subject to the TSX Venture Exchange approval, the Duffitt and Island Pond gold properties located either contiguous to or with the Stony Lake project.  Between 1988-1990, preliminary till and lake sediment sampling located highly anomalous concentrations of gold (Au), arsenic (As) and antimony (Sb), geochemcial indicator elements of gold mineralization in the areas within and surrounding both properties.

Eaglehead Project:

The Eaglehead copper-molybdenum-gold-silver project (15,956 ha) is located in the Liard Mining District in northern British Columbia.  The project is currently on care and maintenance with no work planned for 2019. 

Between 2014 and 2018, District re-logged 94 historical diamond drill holes (26,248m), sampled, re-sampled and re-analyzed 22,697m of drill core from 99 historical drill holes, completed airborne and ground geophysical surveys, preliminary rock characterization testwork and drilled six diamond drill holes (3,413m) to test the continuity of the copper-molybdenum-gold-silver mineralization in the East, Bornite and Pass zones.

Representative mineralized intervals from the various zone located within the property are set out below.  (Note:  The mineralized intervals below do not represent true widths)

Preliminary Metallurgical Testwork
In 2015 and 2016; preliminary rock characterization (“metallurgical”) testwork on mineralized lithologies over a range of copper grades showed that all samples responded well to conventional copper-molybdenite flotation producing a clean concentrate product with recoveries of 89.9% copper, 71.1% molybdenite, 78.6% gold, and 78.1% silver.

In 2017, Copper Fox prepared a report entitled “NI 43-101 Technical Report on the Eaglehead Project” with an Effective Date of July 10, 2017; Robert A. (Bob) Lane, M.Sc., P.Geo. as Qualified Person. The conclusions and recommendations of the Technical Report are summarized below.

  • The Project is at the early to intermediate stage of exploration and hosts a calc-alkalic porphyry copper-molybdenum-gold-silver system of significance. 
  • A multi-parameter exploration program estimated to cost $4.95 million is warranted to more fully evaluate the potential of the Project to host an economic calc-alkalic porphyry Cu-Mo-Au-Ag deposit. 
  • The proposed recommended exploration program includes among other activities 11,000m of drilling, preliminary metallurgical testwork and geophysical surveys.
  • Six zones of copper-molybdenum-gold-silver mineralization occur within a prospective, mineralized corridor (0.5-1.5km in width and in excess of 8km long) characterized by: 
    - a belt of moderate magnetic response with small, irregular-shaped moderate-to-high magnetic features that coincides with the western margin of the Eaglehead pluton; 
    - a 10km long, semi-continuous copper soil geochemical anomaly; 
    - a 6km long, open-ended chargeability-high anomaly, within which five zones of copper-molybdenum-gold-silver mineralization are located.  This anomaly averages 900m wide and is open below a depth of 500m; 
    - a Far East zone, located approximately 3,000m from the end of the chargeability anomaly, exhibits several mineralized drill holes and a 1,000m by 1,000m copper and molybdenum soil geochemical anomaly; 
    - moderate-to-intense potassic (principally K-feldspar), pervasive phyllic (sericitic) and late propylitic alteration of the mineralized intrusive host rocks; 
    - multiple phases of mineralization, consisting primarily of chalcopyrite and bornite with minor molybdenite in quartz veins, quartz stockworks, and zones of fracturing and brecciation; and 
    - drilling has intersected good grades of copper-molybdenum-gold-silver over narrow-to-wide intervals (ranging from 1.5 to 521.2m) in 120 of 126 holes completed to-date

In 2018 District completed the re-logging, sampling and re-sampling of the remaining historical diamond drill holes from the East, Bornite, Pass and Camp zones. This work completes the process of cleaning up the “legacy data” issues related to the Eaglehead project. The 2018 analytical results did not materially change the previously reported analytical results for the drill holes re-sampled in 2018.
