Copper Mountain announces initiation of exploration diamond drill program at the mine

TSX: CMMC

VANCOUVER, May 11, 2017 /PRNewswire/ - Copper Mountain Mining Corporation (TSX: CMMC) (the "Company" or "Copper Mountain") has started a 10,000m exploration drilling program at the Copper Mountain Mine.  The 2017 program is targeting to further extend Pit 2 to the West and to follow up on the pre-2012 drilling that intersected significant mineralization below Pit 2.

Previous drilling by the Company in the Pit 2 Eastern zone intersected a 128m interval grading 1.01% Cu and 0.25g/t Au (including 39m grading 2.33% Cu and 0.38g/t Au) beginning approximately 90m below the current pit bottom in hole 10SD-64.  In addition, hole number 10SD-68 intersected 173m interval grading 0.43% Cu and 0.15g/t Au, while hole number 12P2-19 intersected 123m interval grading 0.52% Cu and 0.27g/t Au. The exploration drilling is designed to better determine the trend and continuity for high-grade mineralization at depth under Pit2.

With the strengthening of the commodity price over the last year and the mine's improved financial position, the Company has allocated modest funds to an exploration drilling program at the mine site. Our focus is to follow up on prior drilling successes to expand the open pit to the west and further test the continuity of higher grade mineralization at depth.
