/PRNewswire/ --

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.
