COPPER MOUNTAIN MINING ACHIEVES 2021 SUSTAINABILITY TARGETS

Copper Mountain Mining Corp. has met or exceeded its sustainability targets for 2021, which were to achieve a "yes" or at least an A rating on each of the Mining Association of Canada's Towards Sustainable Mining (TSM) protocols.

"ESG [environmental, social and governance] is deeply integrated into our business, and meeting or exceeding each of the TSM targets confirms our commitment to mining with integrity," said Gil Clausen, Copper Mountain's president and chief executive officer. "TSM addresses a broad range of critical mining protocols. Those protocols, along with our innovative ESG initiatives, such as our electric trolley assist program, which will launch in the first half of this year, enable us to reduce our greenhouse gas emissions and pave the way to our 2035 net-zero target."

Mr. Clausen added: "The copper we produce is vital to driving the green energy transition and we intend to deliver that value in a comprehensive and responsible way. This aligns with our corporate purpose -- to power a sustainable future."

The TSM external verification was completed by an independent, qualified and certified TSM verification service provider for TSM requirements.

A summary of the protocols, targets and ratings achieved is provided in the attached table.

In addition to the company's efforts to drastically reduce its greenhouse gas emissions, Copper Mountain continues to look for innovative solutions to further its sustainability practices. Beyond trolley assist, Copper Mountain is also collaborating with the British Columbia Ministry of Energy, Mines and Low Carbon Innovation and a few key partners to develop the Mines Digital Trust project. This project uses blockchain technology to attach ESG disclosures to metal production, enabling transparency along the supply chain, allowing third parties to track responsible producers. The company is also focused on minimizing waste through efficiency, recycling and reuse and is working in partnership with Kal Tire to advance haul truck tire recycling.

Copper Mountain is committed to transparent and continuous disclosure of its ESG programs and will continue to provide regular updates on the company's TSM progress and ESG initiatives. Copper Mountain expects to publish its inaugural sustainability report in the second quarter of 2022.
