Mountain Province Diamonds Inc. is a Canadian diamond exploration and development company headquartered in Toronto, Ontario. 
The company’s primary asset is its interest in the Gahcho Kué diamond project, one of Canada’s largest diamond deposits and the largest diamond mine under development globally. Gahcho Kué is a Joint Venture between Mountain Province (49%) and De Beers Canada (51%).

Mountain Province Diamonds is a major partner in the largest new diamond mine under development globally. Through its partnership with De Beers, the Company is well placed to capitalize from the experience of the world's largest diamond producer. 

The Gahcho Kué project is located in Canada, the third largest diamond producing country. By the time the Gahcho Kué mine reaches full production, it is projected that diamond prices will have risen sharply to close what is predicted to be a US$5 billion supply deficit.

Gahcho Kue Project is under the most intense work because of the discovery of the Kennady Lake Kimberlite Field. The Project falls within four mining leases of 21-year tenure held. The mining leases are 100% owned by De Beers Canada Inc. (De Beers Canada), which holds them on behalf of the Gahcho Kue Joint Venture. 
The total area under the lease is 4,189.72 hectares (10,353 acres). The Gahcho Kue Project is located at the Kennady Lake, approximately 300 km east-northeast of Yellowknife in the District of Mackenzie, Northwest Territories (NWT), Canada.
