               of all diamonds including fancies and specials.

               due to the effects of rounding.

Tonnes processed in the month of September reflects the impact of a planned five day shut-down in that month for annual maintenance.  This shut-down was incorporated in the determination of production guidance for 2017, and was successfully executed as planned.

Price experience in the eighth sale is consistent with that reported by the industry generally and reflects the seasonally slow period in the rough diamond sector around Jewish and Hindu New Years' holiday periods.  Also, similar to the seventh sale, realized value per carat in the eighth sale reflects the inclusion of significantly fewer fancies and specials than previous sales, as well as a finer size distribution experienced in the summer's production.  Said Reid Mackie, the Company's Vice President Diamond Marketing, "The October tender sale saw our highest levels of competition to date with an average of 11.8 bids per lot and 145 companies attending.  This strong participation reflects continued deepening of Mountain Province's customer base and interest in our diamond offering.  The result is that Mountain Province's sell through rate is one of the highest among major producers, despite recent market corrections and the traditionally slow lead up to the Diwali holiday period."

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 projected to produce an average of 4.5 million carats a year over a 12 year mine life.

The Gahcho Kué Diamond Mine consists of a cluster of four diamondiferous kimberlites, three of which are being developed and mined under the current mine plan.
