Copper Mountain Announces Robust Preliminary Economic Assessment Results for New Ingerbelle

Copper Mountain Mining Corporation (?Copper Mountain? or the ?Company – http://www.commodity-tv.net/c/search_adv/?v=298239) is pleased to announce that it has completed a Base Case Preliminary Economic Assessment (?PEA?) on its 75% owned New Ingerbelle property (?New Ingerbelle? or ?the Project?), which is located one kilometer from the Company?s flagship operation, the Copper Mountain Mine, in southern British Columbia. ?(Please see Appendix A for New Ingerbelle location map). All dollars are in U.S. dollars unless otherwise indicated.

PEA Highlights

New Ingerbelle is expected to have total production of 768 million pounds of copper and 550,300 ounces of gold over its mine life, based on Measured and Indicated Resources only. The production plan assumes the use of Copper Mountain mine?s existing mine equipment fleet and mill.

?New Ingerbelle represents a low capital, low risk, high quality development project in a world-class mining jurisdiction,? said Gil Clausen, Copper Mountain?s President and CEO. ?Our next steps include evaluating various operational alternatives to test against this Base Case, which assumes supplanting Copper Mountain Mine production. We will study incorporating New Ingerbelle into the Copper Mountain mine plan using the existing mill and study expanding the mill at Copper Mountain to increase the combined annual production.? New Ingerbelle should give us tremendous flexibility as we execute our low risk growth strategy. This PEA demonstrates just how much potential value this project holds.?

Mining and Processing

The New Ingerbelle mine design uses a US$2.75 per pound copper price Whittle pit shell (Measured and Indicated Resources only) generated using actual costs from the adjacent Copper Mountain Mine as a basis. Metal recoveries are based on historical Ingerbelle mill recoveries and metallurgical test work conducted on recent exploration drill core from the New Ingerbelle deposit. ?

The Whittle pit shell was used as the basis for an ultimate design pit, which has a final haul road and waste dump designs incorporated. This ultimate pit was sequenced to produce a life of mine (LOM) plan which includes three pushback phases that include haul roads. ?The study used the haulage profiles to determine mining equipment requirements. Capital and operating costs, along with copper and gold recoveries that were used, are outlined in the tables below.? The PEA is based on the Mineral Resource which was previously published on September 21, 2018. ?

The PEA assumes New Ingerbelle mill feed would be trucked to the Copper Mountain operation, using Copper Mountain?s existing mine equipment fleet, the 40,000 tonnes per day (tpd) mill and tailings facility.? Total mill feed mined is expected to be 175 million tonnes and total waste is expected to be 250 million tonnes for a low strip ratio of 1.43:1.? The production plan for New Ingerbelle is based only on Measured and Indicated Mineral Resources. All 24.6 million tonnes of Inferred Resources mined were considered as waste in the pit optimization and LOM scheduling.

Capital and Operating Costs

The total initial capital cost required to start operations at New Ingerbelle is estimated to be approximately US$130 million. The estimate is largely due to the cost to complete a three-kilometre access road from New Ingerbelle to the Copper Mountain mine, pre-stripping and miscellaneous infrastructure upgrades. Total life of mine sustaining capital is expected to be US$63 million, which is mainly for mining equipment replacement and tailings dam expansions.

Average C1 cash costs, net of by product credits, are approximately US$1.52 per pound of copper. Total operating costs are estimated to be US$9.66 per tonne milled, which includes mining costs of US$3.06 per tonne milled and processing costs of US$5.32 per tonne milled.?

Project Economics

The after-tax NPV assuming an 8% discount rate is US$394 million and the after-tax IRR is 65%.? The economics are based on a long-term Canadian Dollar to U.S. Dollar exchange rate of 1.25 to 1 and bank consensus long-term metal prices of US$3.08 per pound copper, US$1,310 per ounce of gold and US$18.90 per ounce of silver.

The PEA is based on Measured and Indicated Mineral Resources that are included within a Whittle optimized pit shell generated using values based on copper, gold and silver metal prices of US$2.75, US$1,250 and US$16.50 and recoveries of 80%, 65% and 70%, respectively.????
