The 2022 metallurgical drill program completed 4,688 meters ("m") with the objective of collecting samples to complement historical metallurgical test work. The drill program expanded the metallurgical sampling coverage across the Schaft Creek project, with a focus on the early part of the mine life, to better inform metal recoveries and comminution characteristics. Eleven (11) drill holes were completed across the project's mineralized zones; Liard (six holes), Paramount (three holes) and West Breccia (two holes). Highlights and additional details regarding the analytical results received to date are summarized below.
Highlights
The drilling intersected copper-gold-molybdenum-silver mineralization across a range of grades representative of the project life of mine for metallurgical test work. Below are selected intervals from the Liard mineralized zone.
DDH SCK-22-450 intersected 88.0 m grading 0.443% copper, 0.292 g/t gold, 0.022% molybdenum and 1.91 g/t silver starting at 21.0 m downhole. This interval includes 39.0 m of 0.533% copper, 0.250 g/t gold, 0.037% molybdenum and 1.97 g/t silver starting at 21.0 m.
DDH SCK-22-452 intersected 234.55 m grading 0.450% copper, 0.274 g/t gold, 0.019% molybdenum and 2.05 g/t silver starting at 16.0 m downhole. This interval includes 117.0 m of 0.679% copper, 0.558 g/t gold, 0.080% molybdenum and 2.60 g/t silver starting at 46.0 m.
Elmer B. Stewart, President and CEO of Copper Fox, stated, "The mineralized intervals reported in this news release further extend the near-surface higher-grade mineralized zones reported in 2021 and increase the continuity of this type of mineralization between existing drill holes. Receipt of the analytical results from the 2022 metallurgical drilling program allows sample selection for metallurgical test work to commence. Analytical results for the remaining five (5) drill holes will be reported when available."
2022 Metallurgical Drilling Program
Mineralized intervals reported in this news release were calculated using a 0.10 CuEq % copper equivalent cut-off grade. Samples lower than the selected cut-off grade were included in the weighted average interval provided that the sample interval below the cut-off did not exceed 10.0 m in core length. Intervals of lower grade mineralization are reported to demonstrate metal distribution within the drill holes. Information on the drill holes completed, including the weighted average grades of the mineralized intervals, are tabulated below.

Discussion of Diamond Drill Results
The 2022 metallurgical drilling program allows sample selection for metallurgical test work to commence and increases metallurgical sample coverage across the Schaft Creek deposit to better inform metal recoveries and comminution characteristics. The mineralized intervals reported in this news release further extend the near-surface higher-grade mineralization zones reported in 2021 and increase continuity of this type of mineralization between existing drill holes.
Liard Zone
Drill Holes SCK-22-450, DDH SCK-22-451 and DDH SCK-22-452 intersected broad intervals (ranging from 88.0 m to 234.55 m) of near-surface higher-grade copper-gold-molybdenum-silver mineralization. DDH SCK-22-450 also intersected an interval (113.4 m) of higher-grade mineralization starting at 319.8 m downhole. The last sample in DDH SCK-22-450 contained 0.247% copper, 0.265 g/t gold, trace molybdenum and 3.05 g/t silver.
DDH SCK-22-450 was completed at the collar location of DDH SCK-21-448. An attempt to re-enter DDH SCK-21-448, as hole number DDH SCK-22-449, was abandoned due to difficult ground conditions. DDH SCK-22-450 was collared at the same location and was successfully completed to a planned depth of 500m.
Paramount Zone
DDH SCK-22-455 encountered poor ground conditions in the core interval 44.80-94.25 m that resulted in 47% core recovery over this interval. The weighted average grade of the metals for the interval included the estimated core loss.
West Breccia Zone
DDH SCK-22-454 intersected two intervals of copper-gold-molybdenum-silver mineralization separated by a 35.1 m core interval of low metal concentrations. This drill hole extended the limits of the mineralization within this portion of the West Breccia zone. The last sample in DDH SCK-22-454 contained 0.162% copper, 0.016 g/t gold, trace molybdenum and 0.89 g/t silver.
Diamond Drilling and Sampling Procedures
The diamond drilling was completed using HQ diameter core. Overall core recovery was estimated to be greater than 90%. After cutting with a diamond saw, one half of the core was collected for sample preparation and analysis and the other half was retained for future reference. Sample intervals were selected to not cross major lithological or hydrothermal alteration changes and ranged from 0.50 to 2.60 m in length, with most intervals being an average of 2.0 m long. A total of 1,356 samples analyzed at ALS Canada Ltd.("ALS") located in Vancouver, British Columbia are reported in this news release.
Base metal and silver concentrations were determined by ALS MEMS61 package and a 4-acid digestion. Gold concentrations were determined using ALS Au_ICP21 package. ALS has a 9001:2008 International Standard Organization rating. ALS has an ISO/IEC 17025:2017 UKAS (ref 4028) accreditation.
Quality Control
The Joint Venture follows a rigorous Quality Assurance/Quality Control program. Of the 1,356 core samples collected, 163 field blanks and certified reference materials and 107 duplicates were inserted into the sample batches submitted to ALS.
