Diavik proposes to store processed kimberlite, a mine waste, in the mined-out open pits and underground workings. Diavik plans to place mine waste in the pits from 2021 until mine closure in 2025. Diavik will place a minimum 40 m fresh water cap on top of the mine waste in the pits. Post-closure, once water quality is acceptable, Diavik will breach the dikes and reconnect the water in the open pits with Lac de Gras.
