Closely held Dominion, owned by the Washington Companies, filed for creditor protection in April, citing disruption to the global diamond trade caused by the novel coronavirus pandemic.
The deal does not include Dominion’s 40% stake in global miner Rio Tinto’s nearby Diavik mine, which is the subject of a separate dispute between the companies.
The company had this month recalled about 60 furloughed employees in anticipation of a restart.
Ekati, located about 300 km north-east of territorial capital Yellowknife, was Canada’s first surface and underground diamond mine.
Cumulative production through 2016 was 67.8-million carats, according to the latest figures on Dominion’s website.
In October, a sale of the mine to an affiliate of Dominion’s parent company The Washington Companies for $126-million failed to win support of insurance providers.
Washington Companies acquired a controlling interest in the Ekati mine in 2017, as part of $1.2-billion takeover of Dominion.
