Canadian Federal Government Approves Gahcho Kué Diamond Mine Development

De Beers Canada and Mountain Province Diamonds (TSX: MPV, NYSE MKT: MDM) are pleased to announce that the Minister of Aboriginal Affairs and Northern Development Canada, the Hon. Bernard Valcourt, has today approved the development of the Gahcho Kué diamond mine as recommended by the Mackenzie Valley Environmental Impact Review Board.

Tony Guthrie, Chief Executive Officer for De Beers Canada, commented:  "The Minister's approval confirms that the plans for the development and operation of the Gahcho Kué diamond mine meet the highest standards. The new diamond mine will benefit the economy and residents of the Northwest Territories and enhance Canada's position as a premier diamond producer."

Federal government approval allows the Mackenzie Valley Land and Water Board to commence processing of the applications for the Land Use Permit and Water License required to construct and operate the Gahcho Kué mine.

Patrick Evans, Mountain Province President and CEO, added: "Gahcho Kué has gone through the most comprehensive environmental review of any mining project in the Northwest Territories. Through this process, consultation with stakeholders has been extensive. The shareholders of Mountain Province now look forward to an efficient and timely completion of the remaining regulatory process, which is necessary to ensure the optimal development of the Gahcho Kué diamond mine".

Gahcho Kué will employ close to 700 people during the two years of construction and close to 400 people during its operations phase.  It is forecast to produce an average of 4.5 million carats annually over the eleven year mine life.  Gahcho Kué is a joint venture between De Beers (51%) and Mountain Province Diamonds (49%) and is located 280 km northeast of Yellowknife, Northwest Territories.

Given the expected timing for the issuance of a land use permit to enable pioneer work to commence, which requires approximately 42 days for processing, as well as the impact of the winter ice road on logistics, the joint venture is currently reassessing the Gahcho Kué development plan to determine the optimal development schedule. In addition, the joint venture is also updating the 2010 Gahcho Kué feasibility study and expects to announce the results of an Optimization Study early in the New Year. Further details will be announced as they become available.
