NORTHWEST TERRITORIES – The Mackenzie Valley Environmental Impact Review Board has recommended that the Gahcho Kué environmental impact assessment be accepted. The proposed diamond mine 300 km northeast of Yellowknife is a joint venture of Mountain Province Diamonds (49%) and De Beers Canada (51%), the operator.

The letter from the MVEIRB to the federal minister of Aboriginal Affairs and Northern Development Canada said, “The Gahcho Kué Panel recommends … that this development be allowed to proceed subject to implementation of the measures and follow-up programs described in this report which are necessary to prevent potentially significant adverse impacts on the environment.”

A full copy of the report of environmental impact review and reasons for the decision is available at ReviewBoard.ca.

Gahcho Kué is the largest new diamond mine currently under development in the world. The project has probable reserves of 31.3 million tonnes grading 157 cpht or 49.0 million contained carats. Mining will start from an open pit beginning in 2014 or 2015 at a rate of 4.5 million ct/y for 11 years.
