Dominion Diamond Corporation reports Diavik Diamond Mine First Calendar Quarter Production

TORONTO, April 15, 2014 /CNW/ - Dominion Diamond Corporation (TSX: DDC, NYSE: DDC) (the "Company") reports that in the first calendar quarter of 2014, the Diavik Diamond Mine saw continuing strong performance.   During the first calendar quarter of 2014, the Diavik Diamond Mine produced (on a 100% basis) 1.9 million carats from 0.6 million tonnes of ore processed compared to 1.9 million carats from 0.5 million tonnes of ore processed in the comparable quarter of the prior year.

Processing volumes in the first calendar quarter of 2014 were 17% higher compared to the same quarter of the prior year as a result of continuing improvements in mining rates as the underground ramp up progressed to full production from all three kimberlite pipes.  Carat production from first quarter 2014 was 4% lower compared to the comparable quarter of the prior year, primarily as a result of mining and processing a greater proportion of the lower grade A-154 North ore.

The mine plan for calendar 2014 foresees Diavik Diamond Mine production (on a 100% basis) of approximately 6.1 million carats from the mining and processing of approximately 1.9 million tonnes of ore. Mining activities will be exclusively underground with approximately 0.7 million tonnes expected to be sourced from A-154 North, approximately 0.4 million tonnes from A-154 South and approximately 0.8 million tonnes from A-418 kimberlite pipes. In addition to the 6.1 million carats produced from underground mining there will be production from coarse ore rejects ("COR") and production from the improved recovery of small diamonds. 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 which is planned to be processed during calendar 2014 would have produced 0.6 million carats from COR and 0.2 million carats from the improved recovery process.
