The NWT’s Ekati diamond mine is asking regulators for permission to turn its Sable open pit into an underground mining operation. Beginning to mine underground at Sable is an important milestone in Ekati owner Burgundy’s attempt to keep the mine running – in some form – until 2040.
Submitting plans for Sable earlier this month, Ekati urged regulators to provide “timely authorization” of the initial work needed to switch to underground mining.
