Copper Mountain Mining Meets its 2020 Sustainability Targets

VANCOUVER, BC, Dec. 11, 2020 /PRNewswire/ - Copper Mountain Mining Corporation (TSX: CMMC) (ASX:C6C) (the "Company" or "Copper Mountain") is pleased to announce that the Company has achieved a "AAA" rating for its Aboriginal and Community Outreach and a "AA" rating for Safety and Health under the Canadian Mining Association's Towards Sustainable Mining (TSM) standards.  The external verification was completed by an independent, qualified and Certified TSM Verification Service Provider for TSM requirements.

The Company has wholly adopted the TSM standards and has already achieved a "AA" rating for its Tailings Management. Copper Mountain is targeting to achieve at least an "A" rating on the remaining TSM protocols by the end of 2021. These protocols include: Biodiversity Conservation Management, Crisis Management Planning, Energy Use and GHG Management, Child and Forced Labour Free Certification and Water Stewardship.

"We set a target at the beginning of this year to achieve at least a 'AA' rating in these categories and we exceeded our goal," commented Gil Clausen, Copper Mountain's President and CEO. "We take our ESG commitments seriously at Copper Mountain, and our progress demonstrates that commitment.  Setting and achieving these TSM targets is just one example. Another initiative that is currently underway, is our plan to trial electric trolley assist, which has the potential to replace diesel consumption in our haulage fleet with hydroelectricity, thereby reducing Greenhouse Gas Emissions. We are currently partnered with Komatsu/SMS, ABB, the BC government, and BC Hydro to advance this trial. Through hydro electrification and capacity increases, we plan to reduce our carbon intensity by over 50% in five to seven years as we aim to be net zero by 2035. So not only will Copper Mountain be producing the metals that drive a green economy we will deliver that value the right way."

Copper Mountain is committed to transparent and continuous disclosure on its ESG programs and will provide regular updates on its TSM progress and ESG initiatives.
