Progressive Reclamation in Partnership with Indigenous Groups in British Columbia
We plan how we are going to reclaim the areas we mine before we start construction. In some cases, we reclaim at the same time as we extract to expedite the process, which is called progressive reclamation.
At Mount Milligan, our end land use objective is to restore the area to land that is capable of supporting wildlife, recreation and traditional uses by First Nations.
In 2019, we completed reclamation work on approximately four hectares of the south-facing slope of the tailings dam. During the 2019 growing season, Twin Sisters Native Plant Nursery of Moberly Lake, British Columbia, grew approximately 5,040 Sitka alder and 2,000 fireweed seedlings for planting in a portion of the tailings dam slope in 2020. The remaining portion was allocated toward the reclamation trial area. Reclamation research trials began in 2019 with the spring planting of willow stakes in 12 plots across three trial blocks and the measurement of stake survival following the first growing season.
As part of Mount Milligan’s five-year reclamation plan, ongoing collaboration with First Nations groups on research trials will continue. The focus will be on species selection for continued seeding and sampling of native species, surface preparation and treatments, and follow-up effectiveness monitoring.
