Unless otherwise specified, all financial information is presented in U.S. dollars.

Highlights

  • Ekati and Diavik Rough Diamond Sales:
    • Third fiscal quarter diamond sales1 were $102.7 million from the sale of 1.2 million carats (Q3 fiscal 20162 – $145.0 million from the sale of 0.8 million carats).
  • Ekati Production (100% basis):
    • During Q3 fiscal 2017, the Ekati Diamond Mine recovered 1.0 million carats from 0.4 million tonnes of ore processed (Q3 fiscal 2016 – 0.8 million carats recovered from 0.9 million tonnes processed).
    • During the quarter, tonnes of ore processed were significantly reduced as a result of the fire at the Ekati process plant that occurred on June 23, 2016 and the subsequent shutdown of the process plant.
    • The Ekati process plant resumed operations at full capacity on September 21, 2016 and prioritized processing of higher value ore from Misery Main open pit and Koala underground operations.
    • Carat production was positively impacted during the quarter from the processing of a high proportion of high grade Misery Main ore.

(1) Excluded from the Ekati sales recorded in the third fiscal quarter of 2017 is $9.3 million from the sale of 61,000 carats from the processing of material from the Misery Main open pit produced during the pre-commercial production period.(2) Excluded from the Ekati sales recorded in the third fiscal quarter of 2016 is $1.8 million from the sale of 30,000 carats from the processing of material from the Misery Northeast pipe produced during the pre-commercial production period.

SalesEkati and Diavik Rough Diamond SalesThe Company recorded total third fiscal quarter sales of $102.7 million from the sale of 1.2 million carats. Total carats sold increased by 56% and rough diamond sales decreased 29% in the third fiscal quarter versus the prior year primarily as a result of both the process plant fire at the Ekati Diamond Mine, which resulted in a reduction in the value of goods available for sale in the quarter, and the carryover of lower average value goods from both the Ekati and Diavik Diamond Mines in the second quarter of fiscal 2017 for sale in the current period. Two rough diamond sales were held during the quarter. The Company plans to hold three rough diamond sales in the fourth fiscal quarter of 2017.

(1) Excluded from the Ekati sales recorded are carats from the processing of material during a pre-commercial production period. During the third quarter for fiscal 2017, the Company sold 61,000 carats of such production for proceeds of $9.3 million (Q3 fiscal 2016 – $1.8 million from the sale of 30,000 carats of Misery Northeast). For the nine months ended October 31, 2016, the Company sold 210,000 carats of such production for proceeds of $22.0 million (YTD Q3 fiscal 2016 - $7.3 million from the sale of 104,000 carats of Misery Northeast).

The Diamond MarketThe positive market condition of the first half of calendar 2016 was followed in the third quarter by more muted demand as the rough diamond cutting and polishing industry approached the annual shutdown period for Diwali in India. Caution prevailed in the diamond pipeline as polished diamond stocks built up through the quarter, but stable US retail demand has built expectations for a good holiday season beginning in earnest after the presidential election. The market for lower priced rough diamonds was particularly subdued in the third quarter but demand for these goods is cyclical, with decreased demand being typical at this time of year. Demand for these lower priced rough diamonds is expected to return in the fourth quarter.

The retail jewelry market in China was noticeably more active as evidenced by a positive Hong Kong trade show in September. Mainland based jewelers are more upbeat than their Hong Kong based counterparts who are still suffering from subdued demand in the local market. The retail jewelry market in India showed signs of a return to normality in the Diwali period, however local currency restrictions have caused unease amongst jewelry retailers in the run up to the wedding season.

Ekati Production

  • During the period, the Ekati Diamond Mine recovered 1.0 million carats from 0.4 million tonnes of ore processed (Q3 fiscal 2016 - 0.8 million carats from 0.9 million tonnes).
  • The Ekati process plant resumed operations at full capacity on September 21, 2016 and began processing high value ore from Misery Main open pit and Koala underground operations.
  • Carat production was positively impacted during the quarter from the processing of a high proportion of high grade Misery Main ore.
  • Approximately 0.7 million tonnes of Misery Main and Koala ore remained in stockpiles at the end of the third fiscal quarter and a blend of ore from these high value sources will continue to be prioritized for processing through the remainder of fiscal 2017.
  • Mining operations continued during the third fiscal quarter with strong performance from both the Koala underground and Misery Main open pit operations.
  • Mining resumed in late September 2016 at the Pigeon and Lynx open pits. Mining had been paused at these pits in the second fiscal quarter as a cost reduction measure following the process plant fire.

(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 resources, and Misery Northeast material. Approximately 2,500 tonnes of Northeast material was processed during the nine months ended October 31, 2016, at an average grade of 0.98 carats per tonne. The Northeast material is not included in the reserves or resources and is therefore incremental production.(3) This material is not included in the reserves or resources and is therefore incremental production.(4) Figures may not add due to rounding.

Diavik ProductionThe Diavik Diamond Mine production results for the third calendar quarter of 2016 were released on October 19, 2016. Diavik reports to the calendar year ending December 31, and Ekati reports to the fiscal year ending January 31.
