The Ekati Diamond Mine ("Ekati") is Canada's first surface and underground diamond mine. It is located 310 km (190 mi) north-east of Yellowknife, Northwest Territories, and about 200 km (120 mi) south of the Arctic Circle, near Lac de Gras. Until 2014 Ekati was a joint venture between Dominion Diamond Mines (80%), and the two geologists who discovered kimberlite pipes north of Lac de Gras, Chuck Fipke and Stewart Blusson each holding a 10% stake in the mine, until Fipke sold his share to Dominion.
