Copper Fox Provides Update on Schaft Creek PEA

May 13, 2021

Calgary, Alberta–(Newsfile Corp. - May 13, 2021) - Copper Fox Metals Inc. (TSXV: CUU) (OTC Pink: CPFXF) (“Copper Fox” or the “Company”) is pleased to provide an update on progressing the Preliminary Economic Assessment (“PEA”) for the Schaft Creek Project. The Schaft Creek Project is managed through the Schaft Creek Joint Venture (“SCJV”) formed in 2013 between Teck Resources Limited (“Teck”) (75%) and Copper Fox (25%) with Teck being the operator. The Schaft Creek deposit is one of the largest undeveloped porphyry copper deposits containing significant gold, molybdenum and silver by-products in North America. Highlights of the work completed to date are set out below.


  • Improved mine design and plan that significantly reduces the life of mine (“LOM”) strip ratio.
  • A more compact and capital efficient project configuration.
  • Resource base supports a 20-year plus mine life with options to extend mine life and/or increase throughput.
  • Tailings Management Facility designed to accommodate potential future mine life extension/expansion.
  • Lower LOM operating cost per tonne milled compared to the 2013 feasibility study.
  • Preparation of pre-tax cash flow model nearing completion.

Elmer B. Stewart, President and CEO of Copper Fox, stated: “The work completed on the Schaft Creek deposit over the past several years resulted in a number of significant positive changes to the mine plan and infrastructure design. These changes provide a more compact project configuration with positive investment returns that provides options to accommodate mine expansion or mine life extension. The 2021 PEA will include a project configuration comparison with the one envisaged in the 2013 feasibility study.”

Schaft Creek PEA

With input from the SCJV, Tetra Tech Canada Inc. (“Tetra Tech”) and other independent consultants are advancing the Schaft Creek Project PEA. A summary of the major changes to the project description from that set forth in the 2013 feasibility study are outlined below.

Resource Estimate

The Resource Estimate for the Schaft Creek project, prepared by Tetra Tech and reported below, forms the base case used in the PEA under preparation by Copper Fox (please refer to the News Release dated March 22, 2021). The NI 43-101 Technical Report supporting the Resource Estimate has been completed and is filed on SEDAR and the Company’s website.

Mineral Resources are reported using the 2014 CIM Definition Standards.
The QP for the estimate is Mr. Michael F O’Brien, P.Geo., Red Pennant Geoscience.
Mineral Resources have an effective date of 15 January 2021.
Mineral Resources are reported within a conceptual constraining pit shell that includes the following input parameters: $3/lb Cu, $1,200/oz Au, $10/lb Mo, $20/oz Ag, and pit slope angles that vary from 40-44º, metal prices are in US$.
Metallurgical recoveries reflective of prior test work that averages: 86.6% for copper, 73.0% for gold, 58.8% for molybdenum and 48.3% for silver.
Mineral Resources are reported using a net smelter return (“NSR”) cut-off of US$4.31/t.
Totals and Metal Content may not sum due to rounding and significant digits used in calculations.
Copper Equivalent % was estimated using average metallurgical recoveries for copper, gold, molybdenum and silver and metal prices stated in this release.

Mine Plan

The mine plan considers a 21-year mine life, delivering 133,000 tonnes per day (“tpd”) to the processing facility (48.5Mt/year) which represents a 2.5% increase in throughput over the 2013 feasibility study (47.4Mt/yr.). The LOM delivers approximately 1.03 billion tonnes to the processing facility while mining approximately 1.03 billion tonnes of waste resulting in a 1:1 strip ratio compared to the strip ratio of 2.16:1 set out in the 2013 feasibility study. The mine plan includes a stockpiling strategy to ensure constant LOM mill feed grade.

Metal Production

The processing circuit has been designed to process 133,000 tpd at 92% availability and includes crushing, two stage grinding and conventional flotation to produce separate copper and molybdenum concentrates. The project produces 385,000 tonnes of copper concentrate per year at an average grade of 28% copper, 14.2 g/t gold and 63.1 g/t silver. Over the LOM, annual molybdenum concentrate production will average 9,400 tonnes per year at an average grade of 50% molybdenum.

Capital and Operating Costs

The LOM operating cost are estimated to be US$8.66/t processed compared to US$13.25/t processed in the 2013 feasibility study. Capital costs (direct costs, indirect costs, and contingency) are estimated to be US$2.65 billion compared to US$3.26 billion in the 2013 feasibility study. Sustaining capital over the 21-year mine life is estimated to be US$755 million compared to US$1.20 billion in the 2013 feasibility study.


The work completed over the past two years resulted in several infrastructure changes that have reduced or delayed capital expenditures and lowered operating costs in comparison to the 2013 feasibility study. These changes include.

  • The milling facility has been moved closer to the pit to reduce haul distance.
  • Re-design of the Tailing Management Facility contemplates two embankments compared to three in the 2013 feasibility study.
  • The number of waste rock storage facilities has been reduced from three to two.
