Copper Mountain Commences 2018 Drilling Program at New Ingerbelle

VANCOUVER, June 7, 2018 /PRNewswire/ - Copper Mountain Mining Corporation (TSX: CMMC) (ASX: CMMC) (the "Company" or "Copper Mountain") is pleased to announce that it has commenced drilling at the New Ingerbelle deposit at the Copper Mountain Mine, located near Princeton in southern British Columbia. This Phase 2, 10,000m drill program has been designed to follow up on the successful Phase 1, 2017 drilling program which has validated historical data and confirmed that mineralization is open both laterally and at depth.* The objectives of the program are to continue to expand the New Ingerbelle resource area and to convert inferred resources to Measured and Indicated status. A total of 30 holes are planned and the results from this summer program are expected in late Q3.

New Ingerbelle has never been included in the mine plan of the Copper Mountain Mine, nor has the Company reported any New Ingerbelle Mineral Reserves. Its resource categories are currently being updated with the addition of the Phase 1 2017 drill data and will be further updated after the completion of this phase 2 program. The average Cu Eq** grade for 35 significant drill intersections from last year's Phase 1 program* is 0.48% (0.34% Cu, 0.70g/t Ag and 0.22g/tAu ).

The Company's objective under a three phase program at New Ingerbelle is to outline sufficient resources to form the basis of a Feasibility Study on the development potential of this historic producing mine. The Company's target is to add a minimum of 150M tonnes of Measured and Indicated resources in order to commence that study.

Copper Mountain confirms that it is not aware of any new information or data since the release of the historical data included in the Company's press release on October 2, 2017 that affects materially or otherwise the information included in the Company's October 2, 2017 announcement.
