Dominion Diamond Corporation reports Third Quarter Fiscal 2015 Sales and Production Results

Press Release

Yellowknife, Nov. 20, 2014 – Dominion Diamond Corporation (TSX: DDC, NYSE: DDC) (the “Company” or “Dominion”) reports that the Ekati Diamond Mine and the Diavik Diamond Mine performed exceptionally well in the third fiscal quarter of 2015 (August through October). Rough diamond production, sales and pricing have all exceeded plan. Unless otherwise specified, all financial information is presented in U.S. dollars.

Ekati Diamond Mine Production (100% basis)
Consistent with the two previous quarters, diamond production at the Ekati Diamond Mine continued to exceed plan, driven by both higher than expected grades and operational improvements to the processing plant.

Ekati Mining Update
Waste stripping at the Misery pipe progressed according to plan as additional resources were allocated. Concurrently, stripping and mining of COR was initiated ahead of the initial plan to provide additional flexibility for blending at the process plant.  At the Pigeon pipe, this quarter saw the completion of the ring road, the establishment of the waste stockpile area and the beginning of overburden and waste stripping.

Underground production at both Koala and Koala North was slightly ahead of plan for the quarter and development activities at Koala North were completed in August according to plan.

Ekati Processing Update
The Company estimates that process plant improvements implemented over the last 13 months have increased the recovered grade by approximately 15% during the nine month period ending October 31, 2014. The resulting additional diamonds are not currently included in the reserves and the mine plan. During the quarter, physical modifications to the plant were substantially completed with commissioning expected to take place before the fiscal year-end. Once the process improvements have been completed, the Company intends to incorporate these higher recovery rates into an updated reserve statement.
