About Copper Mountain Mining Corporation:

Copper Mountain's flagship asset is the 75% owned Copper Mountain mine located in southern British Columbia near the town of Princeton. The Company has a strategic alliance with Mitsubishi Materials Corporation who owns the remaining 25%. The Copper Mountain mine commenced production in the latter half of 2011, and has continued to improve its operations. The key development for 2014 was the installation of the secondary crusher as a permanent solution to maximize concentrator throughput and improve overall efficiencies for the company. Secondary crusher construction was completed by the end of July 2014 on budget and on schedule. The 18,000 acre site has a large resource of copper that remains open laterally and at depth. The mine has significant exploration potential that will need to be explored over the next few years to fully appreciate the property's full development potential. Additional information is available on the Company's web page at www.CuMtn.com.
