Copper Mountain Mining Achieves 2018 Production Guidance and Announces Three-Year Guidance

VANCOUVER, Jan. 9, 2019 /CNW/ - Copper Mountain Mining Corporation (TSX:CMMC | ASX:C6C)  ("Copper Mountain" or the "Company) announces Q4 and full year 2018 production results for its Copper Mountain mine, located in southern British Columbia. The Company also announces three-year production guidance for 2019 to 2021.  All results are reported on a 100% basis. 

"We are pleased to finish 2018 strong, achieving guidance across all metrics," said Copper Mountain's President and CEO, Gil Clausen. "As we guided, the fourth quarter was our strongest production quarter. The Copper Mountain mine continues to operate predictably and reliably and in line with plan."

Mr. Clausen added, "We expect production in 2019 to be slightly lower than 2018, but as we move forward, production levels are expected to increase materially. We are also currently advancing our technical work to bring the New Ingerbelle Mineral Resources into Mineral Reserves and integrate those reserves into a new life of mine plan technical report for the Copper Mountain Mine.  We are well advanced on this work and on track to deliver the results in the first quarter of 2019.  The integrated life of mine plan results are not included in our current three-year guidance, and have the potential to add significant production value to Copper Mountain."

* Copper Equivalent was calculated based on a Copper price of US$3.00/lb, Gold price of US$1,300/oz, and a Silver price of US$17.00/oz

The Company expects production in 2019 to be between 72 and 80 million pounds of copper, with midpoint slightly lower than 2018 as a result of slightly lower grade mined. Mined grade recovers strongly in the later years, with production expected to be between 86 to 95 million pounds in 2020 and 81 to 89 million pounds of copper in 2021. The three year production guidance does not include any production from the New Ingerbelle pit.  The Company intends to deliver a Technical Report for an integrated Copper Mountain mine production plan, including the New Ingerbelle pit, in the first quarter of 2019.
