Canarc Updates Preliminary Economics for the New Polaris Gold Mine Project, BC; $1500 Gold Price and $0.71 Exchange Rate Improve NPV to US$333 Million and 56% IRR After Tax

Vancouver, Canada – May 20, 2020 – Canarc Resource Corp. (TSX: CCM, OTC-QB: CRCUF, Frankfurt: CAN) announces that an update of the gold price and exchange rate within the range of sensitivities in the 2019 preliminary economic assessment (“PEA”) of the high-grade New Polaris gold mine project in northwestern British Columbia significantly improves the anticipated economics of the project. 

The 2019 PEA used a base case gold price of US$1300 per oz and a $CDN: $US exchange rate of 0.77 to generate an after-tax Net Present Value (“NPV”) of US$216 million and an after-tax Internal Rate of Return (“IRR”) of 38%.  At a US$1500 per oz gold price and a 0.71$CAD: USD exchange rate, the forecasted economics significantly improve to a US$333 million after-tax NPV and a 56% after-tax IRR.

Other benefits of the lower exchange rate include reductions of the cash operating cost from US$433 per oz gold to US$400 per oz gold, and of the payback period from 2.7 years to 1.9 years.  All parameters and conditions of the NI43-101 PEA by Moose Mountain Technical Services (“Moose Mountain”) dated February 28, 2019 PEA remain unchanged.

Scott Eldridge, Canarc’s CEO, stated: “These updated economic assumptions clearly demonstrate the potential for our New Polaris gold mine project to become a high-margin, low-cost gold mine. The 2019 PEA incorporated flotation, bio-oxidation and CIL plant circuits to produce doré gold bars, a game-changer that offers substantial operational and financial advantages over prior plans to ship flotation concentrates by barge and truck to offshore facilities for final processing.”

Summary of New Polaris Operating & Financial Parameters:

  • Post-tax internal rate of return improves to 56% from 38%
  • Post-tax net present value at 5% improves to US$333 million from US$216 million
  • Post-tax project payback improves to 1.9 years from 2.7 years
  • Cash operating cost decreases to US$400 per oz gold from US$433 per oz gold
  • Mine production of 2.3 million tonnes grading 10.3 grams per tonne over an 8.7-year mine life
  • Mill throughput of 750 tonnes per day with a process recovery of 90.5% to produce a total of 693,000 oz. gold
  • Average annual life of mine production: 80,000 oz. gold

Canarc is evaluating the potential to build and operate a 750 tonne per day gold mine at New Polaris using flotation to produce a high grade gold sulfide concentrate, bio-oxidation to oxidize the concentrates, and leaching of the oxidized concentrates to produce 80,000 ounces of gold per year in doré bars onsite.

On a pre-tax basis, the undiscounted life-of-mine cash flow totals CA$847 million with a 68% IRR and a 1.7 year pay-back period; compared to a undiscounted cash flow total of CA$554 million, a 47% IRR and a 2.3 pay-back period in the PEA.  Given the conceptual nature of the PEA, there is no certainty that the preliminary economic assessment will be realized.

Notes for Mineral Resource Estimate:

  • The Mineral Resource Estimate was prepared by Sue Bird, P.Eng. in accordance with CIM Definition Standards and NI 43-101, with an effective date of February 28, 2019.
  • A Mineral Resource is a concentration or occurrence of solid material of economic interest in the Earth’s crust in such form, grade or quality and quantity that there are reasonable prospects for eventual economic extraction. The location, quantity, grade or quality, continuity and other geological characteristics of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge, including sampling.
  • Mineral Resources are reported within a confining underground shape targeting mineralization over 4.0 g/t.  The 4.0 g/t target includes the following considerations: gold price of US$1,300/oz, exchange rate of 0.77 US$:CA$; Payable gold % of 99.9%, Offsite refining costs of US$7/oz, mining costs of CA$65.20/t, process costs of CA$62.70/t, G&A (General and Administration) costs of CA$37.00, sustaining capital costs of CA$19.83/t, and a 90.5% process recovery.
  • An Indicated Mineral Resource is that part of the Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in
  • sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Geological evidence is derived from adequately detailed and reliable exploration, sampling and testing and is sufficient to assume geological and grade or quality continuity between points of observation.
  • An Inferred Mineral Resource is that part of the Mineral Resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
  • Factors that may affect the estimates include: metal price assumptions, changes in interpretations of mineralization geometry and continuity of mineralization zones, changes to kriging assumptions, metallurgical recovery assumptions, operating cost assumptions, confidence in the modifying factors, including assumptions that surface rights to allow mining infrastructure to be constructed will be forthcoming, delays or other issues in reaching agreements with local or regulatory authorities and stakeholders, and changes in land tenure requirements or in permitting requirement.

Project Description:

The 100% owned New Polaris gold mine project is located in north-western British Columbia about 100 kilometers (“km”) south of Atlin, BC and 60 km northeast of Juneau, Alaska. There is no road access at present to the property, but year-round access is available via light aircraft from either Juneau or Atlin to a 400 meter airstrip on the property, and summer access is possible via shallow draft barge from Juneau.

The property consists of 61 contiguous Crown-granted mineral claims and one modified grid claim covering 2,100 acres. All claims are 100% owned and held by New Polaris Gold Mines Ltd., a wholly owned subsidiary of Canarc, subject to a 15% net profit interest held by Rembrandt Gold Mines Ltd. that can be reduced to a 10% net profit interest.

The deposit is an early Tertiary, mesothermal gold mineralized vein system occupying shear zones cross-cutting late Paleozoic andesitic volcanic rocks. It was mined by underground methods from 1938 to 1942, and from 1946 to early 1951, producing approximately 245,000 oz gold from 740,000 tonnes of ore at an average grade of 10.3 g/t gold. Three main veins (“AB, C and Y”) were mined to a maximum depth of 150 m and have been traced by drilling for up to 1,000 m along strike by up to 800 m down dip, still open for expansion.

The gold occurs dominantly in finely disseminated arsenopyrite within the stock-work veins and altered wall-rocks. The next most abundant mineral is pyrite, followed by minor stibnite and a trace of sphalerite. Individual mineralized zones range up to 250 m in length and up to 14 m in width but mineralized widths more commonly average around 2 to 5 m.

Mineral Resource Estimate:

Canarc explored the “C” vein system between 1988 and 1997, and carried out infill drilling in 2003 through 2006, to better define the continuity and grade of the vein systems. The total New Polaris database consists of 1,056 diamond drill holes with a total of 31,514 sample intervals. A Mineral Resource Estimate dated February 28, 2019 was based on ordinary kriging of 174 drill holes, 1,464 gold assay intervals and 1,320 m of drill intercepts within modelled domains.

Targeting mineralization over 4.0 gram per tonne (g/t) gold, a confining shape has delineated a Mineral Resource Estimate:

  • Indicated Mineral Resource totals 1,687,000 tonnes grading 10.8 g/t gold containing 586,000 oz gold.
  • Inferred Mineral Resource totals 1,483,000 tonnes grading 10.2gpt gold containing 485,000 oz gold.

The ROM production tonnes are a subset of the Mineral Resources and are within a confining shape targeting mineralization over 6.0 g/t gold. The mine plan uses a combination of conventional cut and fill and longhole stoping, depending on mineralization thickness and continuity. Development will include a decline from surface, extraction drifts on sublevels across the footwall of the orebody, and ventilation raises to the surface.

An onsite mill will produce a float concentrate feeding a bio-leaching and CIL plant to produce doré.  Process water will go through the ASTER treatment process and reclaim water will be stored in surface settling ponds near the plant.

Tails will be thickened with 42% being pumped underground to a paste plant and dispersal system into mined out voids and the remaining 58% filtered to a semi-dry state and hauled and dumped into a secure co-disposal facility (CDF) with waste rock from the underground development.

Cash costs include all costs to produce a gold-sulphide concentrate followed by Bio-Oxidation and CIL leaching process to produce doré gold bars at site.

This preliminary economic assessment is based on resources, not reserves, and a portion of the modeled resources in the mine plan are in the inferred resource category. Given the inherent uncertainties of resources, especially inferred resources compared to reserves, the New Polaris gold mine project cannot yet be considered to have proven economic viability.
