Copper Mountain Mining Receives Reclamation Award

VANCOUVER, Sept. 22, 2022 - Copper Mountain Mining Corp. (TSX: CMMC) (ASX: C6C) (the "Company" or "Copper Mountain") is pleased to announce it has received the award for Outstanding Achievement in Mine Reclamation in the Metal Mine category from the British Columbia Technical and Research Committee on Reclamation for its reclamation work on the Wolfe Creek Realignment and Fish Habitat Offsetting Plan ("FHOP").

In 2019, Copper Mountain initiated the Wolfe Creek Realignment Project. The project consisted of realigning a section of Wolfe Creek around the Copper Mountain Mine. The FHOP was developed to provide a new higher quality fish habitat to offset a portion of the creek that was fish-bearing. The Company consulted and worked with local First Nations Bands who were involved in the project. Reclamation work consisted of soil applications, seeding and planting trees and shrubs. In 2021, an initial effectiveness evaluation was conducted and indicated that the habitat suitability index values were above average to excellent and that the constructed ponds were providing a suitable rearing habitat for rainbow trout.

"We are proud to receive this award, which recognizes Copper Mountain's environmental stewardship," stated Gil Clausen, Copper Mountain's President and CEO. "As part of our commitment to being a responsible neighbour, we are continuously advancing and scaling up our reclamation and biodiversity efforts. This project exemplifies how we streamline environmental initiatives throughout our operations, aligning with our corporate purpose to power a sustainable future."
