YELLOWKNIFE, Northwest Territories, December 11, 2012 /PRNewswire/ --



Economic benefits for the Northwest Territories and Canada, a comprehensive
environmental plan and extensive engagement with communities and regulators
drew praise from both government and a number of Aboriginal groups that
attended five days of public hearings into the proposed Gahcho Kué Project,
280km northeast of Yellowknife.

Gahcho Kué, a joint venture of De Beers and Mountain Province Diamonds, began
the Environmental Impact Review process in 2006. In December 2011, an 11,000
page Environmental Impact Statement was submitted to the Mackenzie Valley
Environmental Impact Review Board. The Gahcho Kué Panel struck by the Board
held community and public hearings in Dettah, Lutsel K'e and
Yellowknifebetween November 30 and December 7.

De Beers Canada Chief Operating Officer Glen Koropchuk, who provided opening
remarks at the Yellowknife hearings on behalf of the Gahcho Kué JV, said the
years of working collaboratively with the local communities near the Gahcho
Kué site helped shape the project design. "We are confident that the Project
is not only technically sound, but also reflects our commitment to sustainable
development by listening to our community partners and incorporating key input
that makes this project viable and respects local priorities."

The proposed Gahcho Kué Project comes at a time when the GDP of the Northwest
Territories has started to decline due to the reduced output from the
territories' two oldest diamond producers.

Mountain Province Diamonds President & CEO Patrick Evans said: "Since the
discovery of Gahcho Kué 20 years ago, more than $200 million has been invested
in exploration, social and environmental studies, engineering design,
feasibility studies and consultation. This reflects an extraordinary
commitment on the part of our shareholders to the people and diamond industry
of Canada'sNorthwest Territories. Last week's public hearings mark an
important milestone towards the development of Canada's next great diamond
mine. The successful permitting of Gahcho Kué will secure the Northwest
Territories' position as one of the world's leading diamond producing
regions".

During the hearings, a groundbreaking collaborative monitoring forum, Ni Hadi
Yati , was proposed jointly by the Yellowknives Dene First Nation, Lutsel K'e
Dene First Nation, Deninu K'ue First Nation, Tlicho Government and De Beers.
This forum would be funded by the Gahcho Kué JV and is proposed to provide
increased capacity to Aboriginal groups to improve understanding and
involvement in environmental monitoring programs. The North Slave Métis
Alliance and NWT Métis Nation have also been invited to participate.

De Beers and Mountain Province Diamonds wish to thank all those that
participated in the public hearings and throughout the Environmental Impact
Review process and look forward to a positive report from the Gahcho Kué Panel
of the Mackenzie Valley Environmental Impact Review Board.

    our economy and the wellbeing of our people and communities."

    environmental performance and the environmental design."
