NORTHWEST TERRITORIES – Toronto's Dominion Diamond Corp. plans to expand the Ekati diamond mine near Lac de Gras by developing the Jay and Cardinal kimberlite pipes. Toward that end, the company has filed an application with the Wek'éezhii Land and Water Board (WLWB) requesting a new land use permit and a class A water licence.

The Jay and Cardinal kimberlite pipes are located in Lac du Sauvage in the southeastern portion of the Ekati mine property, about 25 km from the main facilities and approximately 7 km to the northeast of the Misery mine. The two pipes are located in the Buffer zone joint venture, in which Dominion has a 58.8% controlling interest. The balance of the buffer zone belongs to Archon Minerals (31.2%) and Chuck Fipke (10%).

The Jay-Cardinal project covers what Dominion says is the largest diamondiferous resource in North America. Drilling at the Jay pipe has outlined 78 million ct of indicated resource (36.2 million tonnes at 2.2 ct/tonne) and 13 million ct of inferred resource (9.5 million tonnes at 1.4 ct/tonne). The project has the potential to extend the life of the Ekati mine 10 to 20 years beyond 2019, when current reserves will be exhausted.

Follow-up delineation drilling is planned at both the Jay and Cardinal pipes for the winter 2014 program.

The detailed Jay-Cardinal project report is available at DDcorp.ca in the Ekati mine section.
