Studies and field tests are conducted to select a strategy that allows us to reuse mine waste to restore the site, rather than use natural material, like clay, sand, and gravel brought in from outside.

In 2019, we began construction of cells to test the efficacy of four coverage possible options. Once completed, the cells will feature an organic layer for vegetation, a key aspect of erosion and moisture control.

Performance data, to be gathered over the coming years, will guide decisions on the ground cover plants that will eventually be planted over the entire tailings pond.

On December 31, 2019, the Government of Québec held $163.4 M in trust to ensure the timely closure of the Canadian Malartic site once mine operations have ceased.
