Mountain Province Diamonds Production Report for the Third Quarter Ended 30 September 2016

Patrick Evans, president and CEO, commented: "We are very pleased that ramp-up production commenced six weeks ahead of schedule. Mining and processing continues to progress well and Gahcho Kué remains on track to achieve commercial production in early 2017."

The first sale of the Company's 49 percent share of the run-of-mine production will take place on open tender in Antwerp during January 2017 and approximately every five weeks thereafter.

The joint venture partners bid for the production of fancy coloured and special (+10.8 carat) diamonds on almost a monthly basis. The bid for August production of fancies and specials was won by De Beers, and the bid for September production was won by Mountain Province. Included in the parcel of fancy and special diamonds from the September production are a 50.25 carat gem quality diamond and three fancy yellow diamonds weighing between 3 and 5 carats. The fancies and specials now owned by Mountain Province will be included in the Company's January 2017 sale.

Mr. Evans added: "The 50 carat diamond recovered in September is the largest diamond recovered to date and provides further confirmation that the Gahcho Kué has a population of large, high quality gem diamonds. It is also exciting to see a population of good size fancy yellow diamonds, which offers encouragement that we'll see further fancy diamonds as the production ramps up."

Mountain Province Diamonds is a 49% participant with De Beers Canada in the Gahcho Kué diamond mine located in Canada's Northwest Territories. Gahcho Kué is the world's largest new diamond mine and is projected to produce an average of 4.5 million carats a year over a 12 year mine life.

Gahcho Kué consists of a cluster of four diamondiferous kimberlites, three of which have a probable mineral reserve of 35.4 million tonnes grading 1.57 carats per tonne for total diamond content of 55.5 million carats.
