Canarc Reports Positive Preliminary Economic Assessment For the El Compas Gold-Silver Mine Project in Zacatecas, Mexico with Low All-In Sustaining Costs Estimated at US$614 per ounce AuEq.
Vancouver, B.C. – January 19, 2016 – Canarc Resource Corp. ( “Canarc” or “Company”) (TSX:CCM,) is pleased to announce the results of a Preliminary Economic Assessment (“PEA”) prepared by Mining Plus Canada Pty Ltd. on the Company’s 100% owned El Compas Gold-Silver Mine, located in Zacatecas, Mexico.
PEA Highlights
All dollar amounts are expressed in U.S. dollars unless otherwise indicated. The base case uses US$1100 / Oz Au, US$14 / Oz Ag and 18 MXN to 1 USD exchange rate.
- Total cash cost of $523 per Oz AuEq Oz and all in sustaining cost $614 per Oz AuEq
- Annual production of 18,000 Oz gold equivalent (AuEq) based on 78.6:1 gold: silver ratio
- 7.3 years mine-life at 450 tonnes per day producing a total of 126,000 net payable AuEq Oz
- $ 48.3 million net present value (“NPV”) and 102% internal rate of return (“IRR”) at a 5% discount rate before taxes and mining duties
- $32.9 million NPV and 84.3% IRR at a 5% discount rate after taxes, tax pools and mining duties
- $7.6 million total pre-production capital expenditures
- 1.8 years after-tax capital pay-back period
- 6 months construction period and 9 months to steady state production
Canarc CEO Catalin Chiloflischi comments: “The PEA clearly indicates that our El Compas Mine has the potential to be an economically robust, low cost, high margin, rapid payback project even at lower metal prices, thanks in part to its high grades, low costs and low capital expenditure requirements. We will now turn our focus to arranging the capital financing needed to develop this attractive gold-silver mine and place it into production.”
The PEA contemplates a 7-year operation involving underground mining using a local mining contractor to produce approximately 18,000 payable gold equivalent ounces per year. Mineralized material will be trucked twenty kilometers from the El Compas Mine to the government-owned La Plata processing plant on which Canarc has secured a long-term lease option with the Zacatecas government.
Processing will involve crushing, grinding and flotation followed by leaching of the flotation concentrate. A 50 tonne per day leach and Merrill Crowe recovery circuit will be added to the existing plant to produce doré bars. Life of Mine payable production will total 115,000 ounces of gold and 886,000 ounces of silver for a total of 126,000 ounces of gold equivalent.
The results of the PEA will be summarized in a technical report prepared pursuant to National Instrument 43-101, which will be filed on SEDAR within 45 days.
Conference Call
Canarc will be hosting a live conference call with shareholders, investors, analysts and bankers on Tuesday January 19, 2016 at 9.00am PST (12.00pm EST) to discuss the PEA results.
The teleconference will be hosted by: Canarc Chairman, Mr. Bradford Cooke, Canarc CEO, Mr. Catalin Chiloflischi and Canarc President, Mr. Garry Biles.

The reader is cautioned that the PEA is preliminary in nature and the PEA mine plan and economic model include the use of Inferred Resources that are considered to be too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. Mineral resources that are not mineral reserves do not have demonstrated economic viability. There is no certainty that Inferred resources can be converted to Indicated or Measured Resources or Mineral Reserves, and as such, there is no certainty that the results of this PEA will be realized.
Opportunities to Enhance Value
Canarc plans to conduct additional exploration drilling, subject to financing, with the goal of converting inferred resources to indicated or measured resources in order to reduce risk in the financial model. Canarc also plans to evaluate alternate processing scenarios that could reduce the initial plant capital requirements and enhance overall project economics even further.
Project History
The El Compas vein was historically mined from 2002 until 2007 via 1,200 metres of ramp mining whereby approximately 55,000 tonnes of mineralized material was shipped to the Veta Grande Mill, averaging 4.7 g/t gold and 87 g/t silver. From 2007 until 2011, Oro Silver completed extensive surface exploration of the property including three phases of drilling totalling 14,263 m in 96 diamond core and reverse circulation holes over portions of the El Compas and El Orito vein systems. In October 2015, Canarc Resources Corp. acquired 100% of the shares in Oro Silver Resources Ltd., a wholly-owned subsidiary of Marlin Gold Mining Ltd.
Mineral Resources
The PEA is based on an Indicated and Inferred mineral resource estimate completed by Lisa Bascombe, AIG (CP), Mining Plus Consultant, an Australian registered Professional Geologist and a Qualified Person.
The resource estimate was derived from 153 drill holes and 41 underground channel samples completed between 2005 and 2010 for a total of 30,069 meters of drilling and 305 meters of underground sampling. This drilling and underground sampling focused on the El Compas and El Orito zones, which account for the majority of metal discovered to date on the project. For further details, please see the Company’s press release dated January 14, 2016.

Notes:
- Mineral Resources estimated as of January 14, 2016
- CIM Definition Standards were followed for the Mineral Resource estimates.
- Mineral Resources are estimated using Vulcan software, and have been reported at a 2 g/t Au cut-off grade.
- For the purpose of resource estimation, assays were capped at 75 g/t for Au and 700 g/t for Ag.
- A bulk density of 2.6 tonnes/m3 has been applied for volume to tonnes conversion.
- Resource categories have been applied to the estimation on the basis of drill-hole density, number of available composites, estimation pass and confidence in the estimation.
- A small amount of the resource has been mined at the top of the El Compas vein and this material has been removed from the resource.
- The estimate includes inferred resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. Mineral resources that are not mineral reserves do not have demonstrated economic viability. There is no certainty that the results predicted by this estimate will be realized. The mineral resources estimate could be materially affected by: environmental, geotechnical, permitting, legal, title, taxation, socio‐political, marketing or other relevant issues.
Infrastructure
El Compas is accessed by an all-weather gravel road, one kilometer from the paved roads in the southern part of the city of Zacatecas. Access is available directly to the existing El Compas mine portal and to the quarry where the new portal will be excavated. Minor roadworks will be required to provide clear and suitable access in and around the new portal site.
Canarc has signed a letter of intent with the Zacatecas state government to lease their fully permitted La Plata flotation mill and tailings storage facility in Zacatecas. The La Plata mill and tailings facility are accessible by paved roads and all weather gravel roads, approximately 20 kilometers from the El Compas mine site around the western side of Zacatecas City.
Mining
The PEA contemplates utilzing an underground mining contractor that will mine at a rate of 450 tonnes of mineralized material per day with contractor direction and supervision by qualified and experienced professional and technical staff employed by the Company to ensure efficient mining of the deposit. Using a mining contractor reduces the upfront mining capital cost significantly and reduces or eliminates much of the training efforts needed when compared to using a mining crew of Company employees.
The geometry of the deposit makes it amenable to a lower cost long hole stoping mining method, with mining dilution and recovery estimated in the range of 12-14% and 91-93% respectively. Underground mining cost is estimated at $32/tonne based on competitive bids from qualified underground mining contractors and a mining development and stoping plan created by Mining Plus Consultants during their PEA study work.
The El Compas Project benefits from it’s location just south of the city of Zacatecas, which is one of Mexico’s historical and current centers for gold and silver mining. This provides the company excellent access to the qualified and experienced people needed to manage and operate the project and easy access to all of the services needed to support the operation.
Processing
Modifications will be made to the La Plata plant to allow for both flotation and cyanide leach circuits. The process flowsheet includes a two-stage crushing plant followed by grinding and flotation operations and cyanide leaching of the flotation concentrate. Leach solutions are processed using a Merrill Crowe recovery system and the resulting precipitate is melted into doré gold-silver bars.
The estimates for gold and silver recoveries and reagent consumptions are based on flotation and leaching test work undertaken at Research Development Inc.’s laboratory which is located in Colorado, US and supervised by Tetra Tech, Inc. personnel. Processing cost is estimated to be around $18 per tonne.
Capital and Operating Costs
Total life of mine capital requirements are estimated at $11.53 million, comprised of $7.65 million of upfront capital requirements and $3.88 million of sustaining capital requirements. A contingency of 15% was applied to upfront mine capital estimations. Mill Capital estimations have a 12% contingency applied. The following tables provide a summary of estimates of upfront capital costs and sustaining capital costs.
