Copper Mountain Mining Announces Improved Feasibility Study Update Results for Eva Copper, Improves NPV and Increases Total Production by 57%

Receive up-to-date information about the company directly via push notification

Vancouver, B.C., May 7, 2020 – Copper Mountain Mining Corporation(TSX:CMMC | ASX:C6C)  (“Copper Mountain” or the “Company” - https://www.commodity-tv.com/play/copper-mountain-mining-q4-and-full-year-2019-numbers-published/ ) is pleased to announce positive results from its 2020 Feasibility Study Update (“2020 FS”) on its 100% owned Eva Copper Project (“Eva” or “the Project”), which is located in Queensland, Australia. The 2020 FS demonstrates significantly improved economics and operating metrics, including a higher after-tax NPV, increased production, lower cash costs and a longer mine life, when compared to the prior 2018 Feasibility Study.   All dollars are in U.S. dollars unless otherwise indicated.

2020 FS Highlights

Economic metrics highlights:

  • After-tax Net Present Value (NPV)(1) at an 8% discount rate of $437 million.
  • After-tax Internal Rate of Return (IRR) (1) of 29%.
  • Total initial development capital $382 million.

“These results demonstrate the high quality nature of the Eva Copper Project,” commented Gil Clausen, Copper Mountain’s President and CEO. “We have improved the Project with higher production, a longer mine life and lower operating costs.  The Blackard and Scanlan deposits were added  to Mineral Reserves, increasing total Mineral Reserves by 46%, and we have made process flow sheet optimizations. Eva Copper has the potential to add significant production and cash flow to our existing solid operating base. While we are and will continue to add value to Eva Copper, it should be noted that we will only move forward with development in the right copper price environment. Eva provides Copper Mountain shareholders with high quality organic growth potential in a low risk jurisdiction.”

Mining

Conventional open pit mining methods, which include drilling, blasting, loading, and hauling, will be employed at the Eva Copper Project. There are seven pits that make up the Project’s mine plan: Little Eva is the primary pit and will be supplemented by progressively mining six satellite pit areas at Blackard, Scanlan, Turkey Creek, Bedford, Lady Clayre, and Ivy Ann.  The pit designs for the seven deposits were based on a Whittle Lerchs-Grossmann optimization at US$2.75 per pound copper price, generated using Measured and Indicated Mineral Resources only. Mining costs are based on a first-principles model based on locally-sourced costs for major inputs.

The mine plan includes mining 551 million tonnes of ore and waste from seven deposits over a mine life of 15 years. Total ore mined is expected to be 170 million tonnes and total waste is expected to be 380 million tonnes, for a waste to ore strip ratio of 2.2 to 1. With an overall copper recovery of 87%, the Project’s total copper production is expected to be approximately 1.5 billion pounds of copper, while gold production would be 205,000 ounces based on a gold recovery of 78%.  Metal production on an average annual basis would be 100 million pounds of copper and 13,650 ounces of gold.   However, the first two years of mining are expected to produce approximately 128 million pounds of copper per year.

 

Processing

The process plant is designed to mill 31,200 tonnes per day (tpd) for an average throughput of 11.4 million tonnes per year.   Sequenced mining from the seven deposits will deliver a mixture of sulphide and native copper ore in a ratio of 75% to 25%.   The sulphide deposits include Little Eva, Turkey Creek, Bedford, Lady Clayre, and Ivy Ann, whereas the Blackard and Scanlan deposits contain both native copper and sulphide ore. The processing flowsheet consists of a crushing, grinding, gravity separation and flotation to recover copper and gold in concentrate form.  The flotation concentrate will be thickened, filtered and stockpiled for shipping to the Mt. Isa Smelter. Full transportation, smelting and refining costs were based on the Company’s existing long-term contract with Glencore’s Mt. Isa Smelter, which is situated 194 kilometres to the SW of Eva Project area.

A key update in the 2020 FS flowsheet from the 2018 Feasibility Study is the change from a SAG mill and pebble crushing circuit to a secondary crusher and High-Pressure Grinding Rolls (HPGR) design. The ball mill has also been upsized in order to support 31.2 kt/d at a P80 target grind of 165 µm. The process plant flowsheet developed for the Eva Copper Project is a standard concentrator design and all the unit operations selected for the plant consist of proven technology and are considered low-risk.

The Project is near existing infrastructure with power available through a 220 kV powerline. Water for the operations will be supplied through a well field located near the processing facility, pit dewatering and water reclaimed from the tailings storage facility, all of which are located on the Company property. The well field has been drilled, pump tested and verified by independent hydrologists as sufficient for the Project’s water consumption needs.

A summary of mining and production parameters is provided below. A summary of the Eva Copper Project’s life of mine production schedule by year is available in appendix 1. A detailed life of mine production schedule by deposit and zone is available in the 2020 FS Technical Report.

Economic Analysis

The after-tax NPV using an 8% discount rate is $437 million and the after-tax IRR is 29%. The economics are calculated using average bank consensus metal prices, which are as follows: for copper, $2.97 per pound in Year -1, $3.03 per pound in Year 1, and $3.04 per pound in Year 2 and long-term. For gold, $1,466 per ounce in Year -1, $1,434 in Year 1 and $1,362 per ounce Year 2 and long-term. The Australian Dollar to United States Dollar exchange rate used was 1.55.   A sensitivity analysis on varying copper prices and other variables was completed on the after-tax NPV (8%) and the results are summarized below.
