Vancouver — A six-hole drill program has outlined a kimberlite body measuring 230 metres by 390 metres at the Knife pipe, 80 km south of Coronation Bay in Nunavut.
De Beers Canada Exploration can earn a 70% interest in the 10-sq.-km property from Rhonda (RDM-V) by spending $10 million on exploration over six years.
Last fall, representative core samples from three drill holes yielded nine macrodiamonds and 208 microdiamonds from 397 kg of kimberlite. One 20-kg sample returned 54 stones weighing 0.04748 carat from a 6-metre interval.
The holes were aimed at delineating the size and internal structure of the body, as well as providing more information on diamond content.
Hole 4 was drilled towards the northwest at a 45 angle and cut 150.5 metres of kimberlite below 21.5 metres of water and overburden.
Hole 5 was drilled to the east at a 60 angle and returned 125.5 metres of kimberlite below 16.5 metres over overburden.
The final hole, hole 6, was drilled to the south at a 60 angle and cut 153 metres of kimberlite below 9 metres of overburden.
Located 270 km north of the Ekati diamond mine, the Knife pipe covers an estimated 6 ha. It has drill-confirmed east-west and north-south dimensions of 230 metres and 390 metres, respectively.
De Beers Exploration Canada, formerly known as Monopros, is a subsidiary of De Beers Consolidated Mines of South Africa.
