Ekati Diamond Mine sorting and selling operations in Canada, Belgium, and India. Ekati Diamond Mine The Ekati Diamond Mine ("Ekati") is Canada's first surface and underground diamond mine. It is located north-east of Yellowknife, Northwest Territories, and about 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.

Permafrost early 1980s. Observed warming was up to 3 °C in parts of Northern Alaska (early 1980s to mid-2000s) and up to 2 °C in parts of the Russian European North (1971–2010). In Yukon, the zone of continuous permafrost might have moved poleward since 1899, but accurate records only go back 30 years. It is thought that permafrost thawing could exacerbate global warming by releasing methane and other hydrocarbons, which are powerful greenhouse gases. It also could encourage erosion because permafrost lends stability to barren Arctic slopes. Arctic temperatures are expected to increase at roughly twice the global rate. The Intergovernmental
