Eaglehead

Northern Fox Copper Inc., a wholly owned subsidiary of Copper Fox Metals Inc., owns 60.4% of the issued and outstanding shares of Carmax Mining Corp. ("Carmax"). Carmax owns 100% working interest in the Eaglehead copper-gold-molybdenum project. The Project covers a total area of approximately 13,540 hectares ("ha") in the Liard Mining Division of British Columbia.

In July 2017 Copper Fox completed a National Instrument 43-101 Technical Report entitled "NI 43-101 Technical Report on the Eaglehead Project", prepared by Moose Mountain Technical Services dated July 10, 2017. The Qualified Person who prepared the Technical Report for Copper Fox was Robert A. (Bob) Lane, M.Sc., P.Geo.

Exploration of the Eaglehead project dates back to the early 1960's. Over the past 50 years, numerous exploration companies conducted various exploration program including soil geochemical surveys, induced polarization surveys, mapping and limited diamond drilling programs. During the course of this 50-year time span, six zones of copper mineralization were located. The drilling intersected varying concentrations of copper mineralization over a 5,000 meter ("m") strike length. Approximately 36,000m of drilling have been completed.

The Eaglehead deposit is hosted in moderate to strong potassic, phyllic and mixed potassic-phyllic altered biotite granodiorite, hornblende quartz diorite and Quartz Feldspar porphyry dikes. Chalcopyrite +/- bornite along with significant concentration of gold-molybdenum-silver occur in fractures, veinlets, disseminations and in late fault and breccia zones. Intervals of higher grade copper mineralization usually occur in late stage structurally controlled zones characterized by intense potassic alteration and bornite.

2014 Exploration
In 2014 Carmax completed the re-logging of selected historical drill core, airborne and ground geophysical surveys and a small diamond drilling program. The four hole (2,229m) diamond drilling program tested the continuity of the copper-molybdenum-gold mineralization in the East and the Bornite zones as was suggested by the chargeability signature. Weighted average metal grades for the mineralized intervals reported by Carmax from the 2014 diamond drilling program are set out below.

The 2014 exploration enhanced the technical understanding of the property and yielded the following conclusions:
  • A 6,000m long chargeability anomaly open to the northwest towards the West zone and to the southeast toward the Far East zone. This anomaly averages 900m wide and is open below a depth of 500m,
  • The Far East zone, located approximately 3,000m from the end of the chargeability anomaly, exhibits a 1,000m by 1,000m copper and molybdenum in soil anomaly and a number of mineralized drill holes.
  • The area located between the East zone and Far East zone is considered a prime exploration target,
  • Re-logging of selected diamond drill cores from all six mineralized zones suggests that Eaglehead could be a 9,000m long porphyry copper system that exhibits the alterations and several generations of mineralization that would be expected in a porphyry system,
  • Mineralized drill holes (120 historical and current) occur over 5,000m of the 6,000m long chargeability anomaly, the areas between the mineralized zones have not been drill tested.
Preliminary Metallurgical Testwork
In 2015, Carmax announced the results of preliminary rock characterization ("metallurgical") testwork from the Eaglehead project.

Copper recoveries to copper concentrate ranged from 77.1% (0.11% composite) to 92.7% (master composite sample) with the corresponding copper concentrate containing between 21.1% and 37.9% copper with metal credits of 11.8 grams per tonne ("g/t") gold and 96 g/t silver. Metal recoveries to the copper concentrate ranged from 65 to 87% for gold, 71 to 80% for silver and 17 to 55% for molybdenum. The concentrate contained low concentrations of arsenic, selenium and tin. Based on the molybdenum content of the concentrate, it is expected that a separate molybdenum concentrate could be produced.

2015 Exploration
In 2015, Carmax's field program focused on the Pass zone. The objectives of the program were to bring the historical drill holes located within this zone into the project database by a combination of re-logging, re-sampling, sampling and diamond drilling. The diamond drilling program consisted of 1,184m of drilling (in 2 drill holes) to test the reported historical exploration results in the Pass zone and to test the chargeability/resistivity signatures outlined in 2014.

Analytical results for the 2015 diamond drilling and the re-sampling for the Pass zone reported by Carmax are shown below:

The 2015 program yielded the following results:
  • significant copper mineralization over at least a 1,000m long portion of the Pass zone. The mineralization remains open on both ends,
  • near surface mineralization in the Pass zone is Cu-dominated which overlies Cu-Mo-Au mineralization at depth,
  • the property shows a crude metal zonation from Cu-Mo in the East zone to Cu-Au in the Bornite zone to Cu in the Pass zone; a horizontal distance of approximately 3.5 kilometers, and
  • some of the intrusive rock on the Eaglehead project exhibit a strong Adakite affinity supporting the potential for a large porphyry copper system, which is consistent with the core observations and results of the geophysical surveys.
2016 Exploration
In 2016, Carmax completed a $1.5 million program consisting of:
  • re-logging historical core in the Pass-Bornite-East zones,
  • sampling and in certain instances re-sampling of historical core where necessary,
  • re-analyzing of the available pulps from historical drill holes, and
  • rock characterization studies to enhance metal recoveries.
At the end of the 2016 program, Carmax has reported re-logging, sampling and re-sampling of 40 historical drill holes from the Camp-Pass-Bornite-East zones, re-analysis of approximately 15,000 pulp and core samples from historical drill core and additional positive preliminary metallurgical testwork results.
