Dominion Diamond Corporation - Reports Diavik Diamond Mine Fourth-Calendar-Quarter Production

Processing volumes in the fourth calendar quarter were 5% lower than the same quarter of the prior year due to the improved processing rates in prior quarters fully exhausting the stockpiled ore by the third calendar quarter. This resulted in only run of mine ore being processed in the fourth quarter.

Carats recovered in the fourth calendar quarter were 25% lower than the comparable quarter of the prior year as a result of lower realized grades in all three ore bodies and a higher proportion of the lower grade A154 North ore being processed in the fourth calendar quarter of 2014 than in the comparable calendar quarter of 2013.

A new mine plan and budget for calendar 2015 has been approved by Rio Tinto plc and the Company.

The plan for calendar 2015 foresees Diavik Diamond Mine production of approximately 6.7 million carats from the mining and processing of approximately 2.1 million tonnes of ore. Mining activities will be exclusively underground with approximately 0.8 million tonnes expected to be sourced from A-154 North, approximately 0.4 million tonnes from A-154 South and approximately 0.9 million tonnes from A-418. In addition to the 6.7 million carats produced from run of mine ore, there will be production from Coarse Ore Rejects ("COR"). This additional production is not included in the Company's ore reserves, and is therefore incremental. Based on historical recovery rates, the tonnage of this material that is planned to be processed during calendar 2015 would produce 0.3 million carats from COR.

The aforementioned mine plan for the Diavik Diamond Mine was prepared by DDMI, operator of the Diavik Diamond Mine, under the supervision of Calvin Yip, P. Eng., Principal Advisor, Strategic Planning of DDMI, and a Qualified Person within the meaning of National Instrument 43-101 of the Canadian Securities Administrators.
