Diavik Diamond Mine is an industrial complex set in a remote, subarctic landscape. It consists of four kimberlite pipes associated with the Lac de Gras kimberlite field and is located on an island 20 km 2 (7.7 sq mi) in Lac de Gras informally known as East Island.
“We need to work for a long time to reveal this. In the next period, we agreed to carry out a joint study under the leadership of ITU, Andrew University and AICU. Three universities will ...
