Copper Mountain Increases Mineral Reserves at Copper Mountain Mine, Provides Life of Mine Production Guidance
VANCOUVER, Oct. 1, 2018 - Copper Mountain Mining Corporation ("Copper Mountain" or the "Company) is pleased to announce an updated Mineral Reserve and Mineral Resource estimate along with updated life of mine production guidance for its Copper Mountain mine ("Copper Mountain Mine" or the "Mine"), located in southern British Columbia. All metrics are on a 100% basis.
"Our Flagship Copper Mountain Mine's longevity provides a solid cash flow base for our new growth projects," Commented Gil Clausen, Copper Mountain's President and CEO. "The production projections in this updated guidance do not include the large Mineral Resource or potential from the New Ingerbelle deposit. We believe extraordinary upside exists as we now begin the evaluation of integrating New Ingerbelle into the Copper Mountain Mine plan."
Life of Mine Production Plan
The Company's life of mine production plan and guidance is based on Copper Mountain Mine's updated Mineral Reserves only. This production plan does not include any other Mineral Resource categories or production from the New Ingerbelle deposit. The Company believes that potential exists to increase production by converting Copper Mountain Mine Resources to Reserves, increasing resources through exploration in addition to the contribution of potential production from New Ingerbelle, which could thereby extend its mine life far beyond current Reserves. The Company is evaluating operational alternatives to incorporate New Ingerbelle into the Copper Mountain mine plan (See September 27, 2018 Press Release for more information on New Ingerbelle).
Total material moved is expected to be 572 million tonnes over 14 years, with total ore mined expected to be 148 million tonnes and total waste expected to be 424 million tonnes. 13.5 million tonnes of inferred resource within the pit shell is treated as waste. Using average recoveries of 79% for copper, 68% for gold and 71% for silver, total production is expected to be 925 million pounds of copper, 333,000 ounces of gold and 4.2 million ounces of silver. A summary of operating metrics is provided below.
| All metrics are on an average annual basis | Years 1-3 | Years 4-10 | Years 11-14 (Stockpile) | Total |
| Annual Ore Mined (kt) | 20,100 | 12,300 | 1,200 | 147,600 |

| Average Annual Silver Production (ozs) | 379,100 | 352,400 | 145,500 | 4,186,300 |
The Company expects an average range of C1 cash cost on a per pound of copper basis, net of by-product credits, to be US$2.10 to US$2.20 for years 1 -3, US$2.35 to US$2.45 for years 4-10 and US$1.75 to US1.85 for years 11-14.
Mineral Reserves and Mineral Resources
Copper Mountain Mine's Mineral Reserve increased 36% to 210 million tonnes, when compared to the December 31, 2017 Mineral Reserve. The Mineral Reserve is included in the Mineral Resource and the effective date of the Mineral Reserve and Mineral Resource is September 1, 2018. The Mineral Resource does not include the New Ingerbelle Mineral Resource. A summary of the Mineral Reserve and Mineral Resource is provided below.
