The discovery of these minerals signaled the presence of kimberlites in a particular area, and chemical analysis of them could distinguish those pipes that might contain diamonds.
In Canada, the search for these minerals would ultimately involve years of lonely work in a nearly uninhabited and inhospitable region (Krajick, 2001).
This article will review the discovery, development, and operation of the mine, which is situated in a remote subarctic setting in the Northwest Territories.
Four kimberlite pipes occur in close proximity—three are being exploited, while the fourth will be brought into production in 2018.
Canada is the world’s second-largest country in terms of land area, but until the 1990s it was not considered an important source of gemstones.
