Gahcho Kue delivers fancies, large stones



Partners Mountain Province Diamonds (TSX: MPVD; NASDAQ: MPVD) and De Beers seem to be finding their stride at the Gahcho Kue mine, in the Northwest Territories.

Mountain Province owns a 49% stake in the open pit mine, while De Beers is the majority owner and operator.
