Ekati Mine, Lac de Gras, Northwest Territories, Canada

Canada's first diamond mine.
Located near Lac de Gras 300 kilometres (186 mi) north-east of Yellowknife.

This first known kimberlite pipe in Canada was discovered at Pointe Lake in 1991 by Chuck Fipke and Stewart Blusson, who had been prospecting in the region for almost ten years, having found kimberlite indicator minerals as early as 1985.
Between 1998 and 2008, the mine has produced 40 million carats (8,000 kg / 17,636 lb) of diamonds out of six open pits. As the high grade ore close to surface was depleted, development was completed to access the ore utilizing underground methods. Two of the open pits (Panda and Koala) have been converted to underground mines.

3.7 Mct diamonds were produced in 2001.
