VANCOUVER, BC, Sept. 28, 2022 /PRNewswire/ - Copper Mountain Mining Corporation (TSX: CMMC) (ASX: C6C) (the "Company" or "Copper Mountain") is pleased to announce an updated Mineral Reserves and Mineral Resources estimate and revised life of mine plan for its 75% owned Copper Mountain Mine, located in southern British Columbia. The new life of mine plan, based only on Mineral Reserves, supports an updated mill expansion scenario to 65,000 tpd ("65ktpd Expansion"), producing a total of 4.1 billion pounds of copper equivalent(1) over a mine life of 32 years with robust economics including an after-tax net present value ("NPV") at an 8% discount rate of $1.24 billion(1).
All metrics are on a 100% basis and all amounts are in U.S. dollars unless otherwise indicated.Highlights:
1.
Based on a C$1.30 to US$1.00 exchange rate and consensus metal prices for years 1, 2, 3 and long-term, respectively, of: $3.73, $3.86, $3.94 and $3.60 per pound copper; $1,796, $1,762, $1,749 and $1,650 per ounce of gold; and $21.86, $22.30, $22.24 and $21.35 per ounce of silver.
2.
Compared to the prior technical report titled "Copper Mountain Mine 65 kt/d Expansion Study and Life-of-Mine Plan NI 43-101 Technical Report" with an effective date of September 1, 2020 and dated November 30, 2020.
3.
For the first 20 years, starting in 2023. The Company reports the non-GAAP financial measure of AIC per pound of copper produced to manage and evaluate its operating performance. See "Cautionary Note Regarding Non-GAAP Performance Measures" in this press release.
"These results illustrate the size and scale of the Copper Mountain Mine," stated Gil Clausen, Copper Mountain's President and CEO. "Our large Mineral Reserves base underpins our updated 65ktpd Expansion study, which estimates total production of over 4.1 billion pounds of copper equivalent over a mine life that will extend beyond 30 years. Increasing plant capacity to 65ktpd requires only modest initial development capital, which is self funded with mine cash flow. In fact, not only is the Copper Mountain Mine able to fund capital required over the life of mine, but it is also expected to generate significant free cash flow beyond these requirements. In addition, higher-grade exploration upside remains, particularly at depth, providing further reserve expansion potential. With Mineral Reserves at the Copper Mountain Mine continuing to grow, the Company's total Mineral Reserves estimate, including at the Eva Copper Project, is now at 5.4 billion pounds of copper and over 2.6 million ounces of gold. We have two large, scalable assets in two of the best mining jurisdictions in the world."
The Executive Summary of the NI 43-101 technical report (the "2022 Technical Report") for the new life of mine plan for the Copper Mountain Mine is available on the Copper Mountain website at www.CuMtn.com. The Company will file the full 2022 Technical Report on SEDAR ( www.sedar.com ) within the next seven days and such report will be available at that time on the Company's website.Mining & Processing
The 65ktpd Expansion includes a new primary crusher feed hopper, modifications to the primary gyratory crusher, the installation of a High-Pressure Grinding Roll (HPGR) circuit, the addition of a fourth ball mill, a regrind verti-mill, additional rougher and cleaner flotation circuit capacity, and electrical system upgrades. The existing SAG mill will be retired. The fourth ball mill, a 22 ft by 38 ft mill, will be installed adjacent to the third ball mill within the existing building. With the addition of the fourth ball mill, the ball milling line will comprise four mills operating in parallel: two identical 24 ft x 30 ft mills, and two identical 22 ft x 38 ft mills (see Appendix 2 for the proposed 65ktpd process flowsheet). This work will allow for increased throughput with a slightly coarser grind size P80 of 165 µm as compared to the current grind size of 150 µm.
The 65ktpd Expansion is a planned plant-wide improvement that increases throughput in addition to:
The mine plan is based only on Proven and Probable Mineral Reserves at the Copper Mountain Mine, and indicates a 32-year life of mine, which comprises 30 years of mining and milling followed by 2 years of processing the low-grade stockpiles. The plan indicates average copper equivalent production of 138 million pounds per annum for the first 20 years starting in 2023. The increased milling rate to 65,000 tonnes per day is planned to commence in 2028. The additional mining equipment required includes one additional shovel, 21 haul trucks and one additional drill for a total of five shovels, 49 220-t haul trucks and six blasthole drills. The 65ktpd Expansion also includes Trolley Assist on the East haul road.
Significant exploration potential remains at the Copper Mountain Mine with mineralization open both laterally and at depth. Multiple historical drillholes end in copper mineralization and geophysical data suggests the copper deposit extends below the current known resource.
Total ore mined is expected to be 652 million tonnes and total waste mined is expected to be 1,356 million tonnes, with a strip ratio of 2.08:1. Using average recoveries of 87.9% for copper, 66.8% for gold and 68.2% for silver, total production is expected to be 4.1 billion pounds of copper equivalent composed of 3.4 billion pounds of copper, 1.6 million ounces of gold and 11.6 million ounces of silver. A summary of mining, processing and production metrics is provided below. A more detailed life of mine production schedule will be available in the 2022 Technical Report on SEDAR.

The initial capital cost required to increase throughput to 65,000 tonnes per day is estimated to be approximately $237 million. This includes the installation of the HPGR circuit, buildings, fourth ball mill, regrind circuit, verti-mill, additional rougher and cleaner flotation circuits, and electrical system upgrades. Other development capital requirements estimated at $223 million subsequently required over the remaining mine life, include additional mobile mining equipment, the East haul road Trolley Assist and water management related expenditures.
Total sustaining capital for the life of mine is estimated to be $828 million. With the 65ktpd Expansion's significant increase in Mineral Reserves and mine life, an additional replacement cycle for the mining fleet has been factored into the sustaining capital estimate which contributes to most of the total estimate.

AIC per pound of copper produced is a non-GAAP financial measure. See "Cautionary Note Regarding Non-GAAP Performance Measures" in this press release.
Total LOM operating unit costs are estimated to be $10.14 per tonne milled, which includes mining cost per tonne milled of $5.75, milling cost per tonne milled of $3.87 and G&A cost per tonne milled of $0.51. Mining cost per tonne mined is estimated to be $1.70. A unit cost breakdown is provided below.

Notes: Mining costs are inclusive of costs to rehandle the existing ore stockpiles.
The above costs result in an average AIC per pound of copper of $1.76 for the first 20 years of mine life.Economics
The after-tax NPV for the 65ktpd Expansion at the Copper Mountain Mine assuming an 8% discount rate is estimated to be $1.24 billion. The economics are calculated assuming a Canadian Dollar to U.S. Dollar exchange rate of 1.30 to 1 and long-term metal prices of $3.60 per pound copper, $1,650 per ounce of gold and $21.35 per ounce of silver. Metal price assumptions are based on consensus forecasts. A sensitivity analysis on varying copper prices was completed on the after-tax NPV (8%) and the results are summarized below.
