Dominion Diamond Corporation Reports Fiscal 2017 Fourth Quarter and Year-End Sales, Ekati Diamond Mine Production Results and Fox Deep Drilling Update
Dominion Diamond Corp. (TSX: DDC, NYSE: DDC) (the “Company” or “Dominion”) reports Ekati Diamond Mine and Diavik Diamond Mine fourth fiscal quarter 2017 (November through January) sales and Ekati Diamond Mine production results. Unless otherwise specified, all financial information is presented in U.S. dollars.
Highlights
- Sales:
- Fourth fiscal quarter diamond sales1 were $129.9 million from the sale of 1.4 million carats (Q4 fiscal 20162 - $178.1 million from the sale of 1.1 million carats).
- Ekati Production (100% basis):
- During the fourth fiscal quarter 2017, the Ekati Diamond Mine recovered a record 2.3 million carats from 1.0 million tonnes processed (Q4 fiscal 2016 - 1.2 million carats from 0.9 million tonnes processed).
- Carat production increased by 93% compared to the same period in the prior year due to the positive impact of processing of a large proportion of high grade Misery ore.
- Ekati Fiscal 2018 Mine Plan
- During fiscal 2018, the Company plans to produce 6.3 to 7.0 million carats from the processing of 3.7 to 4.0 million tonnes (fiscal 2017: 5.2 million carats from the processing of 2.9 million tonnes).
- The Company expects to process primarily high value ore from the Koala underground and Misery Main pipes during the first quarter fiscal 2018, with an increased proportion of ore from the Pigeon and Lynx pipes during the remainder of the fiscal year.
- The fines dense media separation (Fines DMS) plant, which increases the recovery of diamonds smaller than 1.2 millimetres, continues to ramp up through the first fiscal quarter, and is expected to be fully operational during the second fiscal quarter.
- Fox Deep Drilling Program
- Based on encouraging results from a reverse circulation drilling campaign this winter, including an average bulk sample grade of 0.38 carats/tonne, a prefeasibility study on Fox Deep is now underway, and is expected to be completed in late fiscal 2018.
(1) Excluded from the Ekati sales recorded in the fourth quarter of fiscal 2017 were $5.1 million from the sale of pre-commercial production from the Misery Main open pit.
(2) Excluded from the Ekati sales recorded in the fourth quarter of fiscal 2016 were $2.5 million from the sale of pre-commercial production from the Misery Northeast pipe.
Sales
Ekati and Diavik Rough Diamond Sales
The Company recorded total fourth quarter fiscal 2017 sales of $129.9 million from the sale of 1.4 million carats. Total rough diamond sales decreased 27% in the fourth fiscal quarter compared to the same period in the prior year. This was due primarily to a reduction in the goods available for sale following the process plant fire at the Ekati Diamond Mine. Sales in the quarter were also negatively affected by the disruption in normal trading activity following the demonetization of the Indian rupee in November 2016. Total carats sold in the fourth fiscal quarter increased by 24% from the same period in the prior year, due primarily to the availability for sale of rough diamonds from high grade Misery Main ore. Total carats sold in the fourth fiscal quarter of the prior year were negatively impacted by the decision to hold back lower-than-average priced inventory due to a weakened diamond market. Three rough diamond sales were held during the quarter. The Company plans to hold two rough diamond sales in the first quarter of fiscal 2018.

The Diamond Market
The market ended the year on a positive note despite the divergence between the resilient market for larger better goods and the more challenging situation for the smaller cheaper goods. The Christmas season in the U.S. failed to meet market expectations, but this was balanced out by renewed retail activity over the Chinese New Year, resulting in an anticipated rise in polished demand from China in the first quarter of 2017.
The Indian retail market has started to recover from the jewelers’ strike in the middle of the year and the impact of demonetization of the Indian rupee towards year-end. The latter is expected to continue to have a dampening effect on the Indian retail jewelry market in the short-term, with demand expected to return to normal in this sector by the fall of 2017. Much of the manufacturing sector that focuses on lower price rough diamonds was brought to a standstill by the demonetization. However, the segment of the manufacturing sector that focuses on higher priced rough diamonds, and produces primarily for the export market, has been less disrupted.
Ekati Production
- During the fourth fiscal quarter 2017, the Ekati Diamond Mine recovered a record 2.3 million carats from 1.0 million tonnes of ore processed (Q4 fiscal 2016 - 1.2 million carats from 0.9 million tonnes processed).
- Carat production was positively impacted during the quarter by the processing of a large proportion of high grade Misery Main ore, resulting in a 93% increase in carat production compared to the same quarter of the prior year.
- Approximately 0.3 million tonnes of Misery Main and Koala ore remained in stockpiles at the end of the fourth fiscal quarter, and a blend of ore from these high value sources will continue to be prioritized for processing in the first fiscal quarter 2018.
- Waste stripping continues at the Lynx pipe with first ore expected to be delivered to the process plant in the second fiscal quarter 2018.

(1) As different ore sources are blended during processing, carats and grade per pipe are estimated using the block models for the ore processed from each pipe, adjusted for the overall reconciliation of total carats recovered against the model. The total carats produced include all incremental production arising as a result of the changes made to the Ekati process plant to improve diamond liberation.
(2) The Misery Satellites include the Misery South and Southwest satellite pipes, which are inferred mineral resources, and Misery Northeast material. Approximately 2,500 tonnes of Northeast material was processed during the year ended January 31, 2017, at an average grade of 0.98 carats per tonne. The Northeast material is not included in the mineral reserves or mineral resources, and is therefore incremental production.
(3) This material is not included in the mineral reserves or mineral resources and is therefore incremental production.

Diavik Production
The Diavik Diamond Mine production results for the fourth calendar quarter of 2016 were released on January 16, 2017. Diavik reports to the calendar year ending December 31, and Ekati reports to the fiscal year ending January 31. The Company does not report Diavik fiscal production results.
Fiscal 2018 Mine Plan – Ekati Diamond Mine
| Run of Mine Production – Fiscal 2018 Ekati Diamond Mine (100% basis) | Tonnes Mined | Tonnes Processed (millions) | Carats (millions) | |||
| Mine Plan for Fiscal 2018 | 27 - 30 | 3.7 – 4.0 | 6.3 -7.0 |
Open pit mining will take place at all pipes, with the exception of Koala, where mining is underground. Processed ore and recovered carats will be sourced from the following kimberlite pipes in the approximate proportions noted below:
| Ekati Kimberlite Pipes | Percentage of Tonnes | Percentage of Carats | ||
| Mineral Reserves Only Base Case | ||||
| Koala Underground | 30% | 10% | ||
| Pigeon | 30% | 5% | ||
| Misery Main | 20% | 60% | ||
| Lynx | 5% | 5% | ||
| Total (Base Case only) | 85% | 80% | ||
| Misery Southwest(1) | 15% | 20% | ||
| Total (Operating Case) | 100% | 100% | ||
(1) Misery Southwest pipe is currently an inferred mineral resource. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Inferred mineral resources are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the Operating Case will be realized.
Mine Plan Key Timeline
- A high-value blend of primarily Misery Main and Koala underground ore will continue to be prioritized for processing in the first fiscal quarter.
- The processing of significant amounts of Pigeon and Lynx ore is expected to begin in the second fiscal quarter, with a corresponding reduction in Misery Main and Koala underground ore.
- Lynx ore is planned to be processed primarily during the second and third quarters of fiscal 2018, and will be replaced by Misery Southwest material in the fourth fiscal quarter while waste stripping is being completed for the second phase of mining at the Lynx open pit.
- The Fines DMS plant continues to ramp up through the first fiscal quarter, and when fully operational in the second fiscal quarter, is expected to result in the recovery of a higher proportion of small diamonds.
Fox Deep Drilling Program
The Company has received the results of a reverse circulation drilling campaign conducted this winter at the Fox pipe, below the previously-mined open pit. Three holes, with a drill hole diameter of approximately 24 inches, were drilled to depths ranging from 448 metres to 600 metres, producing a sample of approximately 1,000 dry tonnes. The Saskatchewan Research Council processed the drill hole interval samples, and a total of 378 carats were recovered at a 1.0 millimetre bottom cut-off, for an average bulk sample grade of 0.38 carats per tonne. Based on these encouraging results, a prefeasibility study is now underway at Fox Deep, and is expected to be completed in late fiscal 2018.
