Canada's federal government says the proposed expansion of the Northwest Territories' Ekati diamond mine doesn't need a second environmental review. That's good news for Dominion Diamond Corporation, which hopes to begin construction on the expansion in the second half of 2016, but it's not good news for the Kitikmeot Inuit Association (KIA). The KIA wants the Nunavut review because the Jay project lies within the Lac de Gras watershed. All water from the watershed goes to the Coppermine River, a popular canoeing destination and source of drinking water and fish for the Inuit of Kugluktuk. Dominion Diamond is pleased to avoid the delay: the company wants to begin mining from the Jay pit before Ekati's existing reserves run out in 2020, and avoid laying off workers. The expansion is expected to add 10 years to the mine.
