[2][3][4] The mine, which opened officially on 20 September 2016, consists of the Gahcho Kué kimberlite pipes, which lie underneath Kennady Lake.

In 1997, Monopros, now De Beers Canada, took over the camp when they joined the Mountain Province Mining Joint Venture.

De Beers and its partners approved it in June 2011 and are preparing a plan and budget for a final decision on whether to go ahead with the mine project.

De Beers appealed this decision to the NWT Supreme Court, but was denied in April 2007, and the review process began in 2007.

De Beers gave notice in November and filed the EIS on 23 December 2010, and after some subsequent revisions to address a few deficiencies, the MVEIRB accepted it on 26 July 2011.

The site consists of open pits, a concentration and recovery plant that converts kimberlite ore to rough diamonds, and support facilities including a camp, airport, and other infrastructure.
