Diamond Exploration in Northern Ontario with Reference to the Victor Kimberlite, Near Attawapiskat

The phased approach used by De Beers for diamond exploration is briefly outlined. The Victor kimberlite is one of 19 kimberlites in a cluster near Attawapiskat, Ontario. The progress at the Victor kimberlite is summarized, and the operations are described within the framework of this staged approach. An evaluation program is currently under way on the Victor kimberlite, but although results are encouraging, insufficient diamonds have been recovered to permit disclosure of estimates for the grade and value.
