DIAMONDS: Mountain Province makes first diamond sale

NORTHWEST TERRITORIES – Mountain Province Diamond of Toronto has made its first sale of diamonds from the Gahcho Kue mine 280 km northeast of Yellowknife. The company owns 49% of the mine, and the operator, De Beers Canada, holds the other 51%.

Mountain Province sold 49,420 ct in Antwerp, Belgium, between Jan. 16 and 25, for about US$6.27 million or an average price of US$127 per carat. About 75% of the parcels offered were sold. The balance, smaller brown and lower quality diamonds, were withdrawn from the sale. The company is planning its next sale for Feb. 20, 2017.
