Diavik Diamond Mine
Located in one of the world’s most challenging environments, on an island in the remote tundra of Canada’s Northwest Territories, the Diavik Diamond Mine is an unincorporated joint venture between Diavik Diamond Mines (2012) Inc. and Dominion Diamond Diavik Limited Partnership. Diavik Diamond Mines is a subsidiary of Rio Tinto plc of London, England, and Dominion Diamond Diavik Limited Partnership is owned by Dominion Diamond Corporation of Yellowknife, Canada.The Diavik Diamond Mine, which began operations in 2003, includes four kimberlite ore bodies called A154 North, A154 South, A418, and A21. To open-pit mine the A154 and A418 kimberlites, which were located under shallow waters of Lac de Gras, Diavik constructed two water retention rockfill dikes. The open-pit mining phase of these three kimberlites concluded in 2012 at which time Diavik successfully transitioned to an all underground mine. In November 2014, Rio Tinto announced a major investment in Diavik; US$350 million for development of the A21 kimberlite ore body, to be funded by the joint venture. A21 development, which will include construction of a rockfill dike, has begun and production from this ore body is expected to begin in 2018. Diavik’s ore reserve and current mine plans indicate production continuing to 2023.
