Copper Mountain Mining Announces Updated Economics and Development Plan for Eva Copper Project

December 13, 2021

Canada NewsWire

VANCOUVER, BC , Dec. 13, 2021  /CNW/ - Copper Mountain Mining Corporation (TSX: CMMC) (ASX: C6C) (the “Company” or “Copper Mountain”) announces updated economics, including capital and operating costs (” December 2021  Update”) for its 100% owned Eva Copper Project (“Eva” or “the Project”) located in Queensland, Australia . All other technical aspects of Eva, including mining, processing, production plan, and Mineral Reserves and Mineral Resources, remain unchanged from the NI 43-101 Technical Report for the Eva Copper Project – Feasibility Study Update, with an effective date of January 31, 2020  , and a report date of May 2020  and filed on SEDAR under the Company’s profile at www.sedar.com (the ” May 2020  Feasibility Study”). (Australian dollars are indicated as A$ and U.S. Dollars are indicated as US$).

“Eva’s project economics are strong and have improved compared to the May 2020  Feasibility Study,” commented Gil Clausen , Copper Mountain’s President and CEO. “The current inflationary environment prevalent globally, particularly for some material and labour supply in Queensland Australia , has resulted in some Project capital cost escalation. We believe this impact will ease as the local economy opens fully after COVID-19 restrictions lift, materials flow regularly, and labour pressures relax over the next six to 12 months.”

“The Company will continue to adhere to a disciplined project execution plan to closely manage capital expenditures and the project schedule. With that approach, our Board has now formally approved the plan to construct the Project subject to advancing detailed engineering to 80% completed; obtaining committed project financing; and the lifting of COVID-19 restrictions in Queensland , Australia. Upon satisfaction of these items, the Company will be able to fix a construction start date. We expect this detailed engineering work to require approximately six months to complete during which time the Company will secure commitments on certain critical long lead-time equipment. This project execution plan approach reduces development risk but will have a four to six-month extension to the original project schedule. The Company now anticipates Eva Mine commissioning in late 2024, provided the above conditions are met,” added Mr. Clausen.

Mr. Clausen continued, “We will fund the expenditures for moving the Project through detailed engineering and to secure long lead items with current cash on hand.  We expect to fund the full development of Eva through conventional bank project debt financing and internal cash flow. The project financing process is well advanced, with closing expected for mid- 2022.  We are excited to formally advance Eva, which is expected to add over 100 million pounds of copper production per year, given the ever increasing and important role copper will play in a green economy and the limited number of other copper projects currently in development globally.”

Summary of Metrics

The December 2021  Update compared to the May 2020  Feasibility Study is provided below.

After-tax NPV (8%) (2,3)




After-tax IRR (2,3)

Long-term Gold Price (2,3)





The Company reports the non-GAAP financial measure of C1 cash costs per pound of copper to manage and evaluate its operating performance. For further information, see “Cautionary Note Regarding Non-GAAP Performance Measures”.


Metal prices for the Dec 2021 Update is based on the forward curve to 2028 (2024 of US$4.30/lb and US$1,706/oz Au; 2025 of US$4.25/lb Cu and US$1,598/oz Au; 2026 of US$4.00/lb and US$1,598/oz Au; 2027 of US$3.75/lb and $1,598/oz Au) and long-term consensus pricing thereafter of US$3.39/lb Cu and US$1,598/oz Au.


Metal prices for the May 2020 Feasibility Study were based on consensus pricing of Year 1 of US$3.03/lb Cu and US$1,434/oz Au and Year 2 and long-term prices of US$3.04/lb Cu and US$1,362/oz Au.

Eva’s after-tax net present value (NPV), based on an 8% discount rate is now $622 million , a 42% increase compared to the May 2020  Feasibility Study. The main factor for the value growth is higher metal prices, offset by a stronger Australian dollar and higher capital. A variance analysis comparing the after-tax NPVs in the December 2021  Update and the May 2020  Feasibility Study is provided below.

Total initial development capital for the Project is estimated to be approximately A$836 million , including a contingency of A$76 million . A summary of the total initial development capital by area in Australian Dollars is provided below.

Owner’s Costs
















Initial development capital in the December 2021  increased by approximately 18.7% compared to the May 2020  Feasibility Study.  A summary of the variances by main area is provided below.

Cost increases in steel, mechanical, concrete, and construction labour were the most significant drivers in the higher capital costs, particularly in the processing area. Raw material and finished equipment costs have been impacted by shortages as COVID restrictions remain tight, especially in Queensland.  Higher estimated infrastructure costs were mainly driven by an expanded camp facility, power infrastructure, and water development, with lower mining equipment costs marginally offsetting the overall higher capital costs in other areas. The total life of mine sustaining capital in the December 2021  Update is estimated to be US$46.6 million , compared to US$33.8 million in the May 2020  Feasibility Study. This increase in sustaining capital is mainly due to higher sustaining mining equipment costs as well as appreciation in the A$ to US$ exchange rate. Sustaining capital is comprised of rehabilitation costs and mining equipment.

The average life of mine C1 cash cost per pound of copper in the December 2021  Update is estimated to be US$1.53  , net of by-product credits. This cost compares to US$1.44  per pound of copper in the May 2020  Feasibility Study. The increase in C1 cash cost is due to A$ to US$ exchange rate appreciating from 1.55 to 1.40.

Project Plan

The Company has formally approved the development of Eva, contingent on completing detailed engineering to at least 80%, which is expected to take approximately six months, project financing committed, and the lifting of COVID-19 restrictions in Queensland, Australia . The advancement of detailed engineering will minimize project execution risk and allow the Company to establish a more significant component of fixed-price contracts for major scope elements. The Company also intends to place deposits on long lead capital equipment during this period. Total project expenditures for the first half of 2022 are estimated to be approximately A$40 million . Detailed engineering is planned for completion, to at least an 80% level, in Q3 of 2022.

The Company’s current cash will fund the near-term project expenditures. The Company also plans to finance the development expense of Eva through conventional project bank debt and internal cash flow. Copper Mountain continues to advance the project financing process and expects it to close mid-2022.
