LONGUEUIL, Quebec, July 10, 2019 — Stornoway Diamond Corporation (TSX-SWY; the “Corporation” or “Stornoway”) announces production and sales results at the Renard Diamond Mine for the quarter ended June 30, 2019. Highlights are as follows:

(All quoted figures in CAD$ unless otherwise noted)

  • 460,832 total carats sold in two tender sales for gross proceeds1 of $47 million2 at an average price of US$76 per carat ($102 per carat2). In terms of total carats sold, pricing and gross proceeds, this represents variations of +7%, -9% and -1% over the first quarter, respectively. Second quarter diamond sales represent diamonds recovered during the first quarter.
  • Second quarter diamond production was 463,136 carats recovered from the processing of 695,934 tonnes of ore at an average grade of 67 carats per hundred tonnes (“cpht”). Carats recoveries increased by 4% compared to the first quarter, mainly due to greater plant utilization. The average processing rate was 7,648 tonnes per day, above the budgeted rate of 7,000 tonnes per day.

Patrick Godin, President and CEO of Stornoway, commented “During the second quarter, both mining and processing operations at Renard have demonstrated strong performance, with an average ore hauling rate of 6,813 tonnes per day from the underground mine, and an average processing rate well above the budgeted rate. The average grade recovered is lower than for the first quarter, as a result of mining of lower grade ore blocks from the block cave sequence at Renard 2. The average grade is anticipated to increase for the remainder of the year, as the extraction of higher grade production ore from the Renard 3 kimberlite pipe ramps up, and with the development of the second underground mining horizon of Renard 2, also of higher average grade. The rough diamond market continues to be challenging, with further decreases in pricing observed during the second quarter sales. Nevertheless, the Corporation maintained comparable gross proceeds relative to the first quarter, as volume of carat sold increased.”


Two tender sales were completed during the second quarter from diamonds recovered between December 27, 2018 and March 29, 2019. Table 1 summarizes second quarter sales results and compares these results to those of the first quarter of 2019 and to those of the second quarter of 2018. Table 2 provides a breakdown between run-of-mine and supplemental diamonds sold.

The achieved pricing of US$76 per carat for all goods sold during the quarter represents a decrease of 9% compared to the first quarter of 2019, attributed to weak market conditions. During the second quarter, pricing of higher quality goods and specials was also negatively affected by the oversupply of rough diamonds relative to demand, the high inventory levels in the mid stream and the reduced availability of bank financing in India. Smaller and lower quality goods continue to sell at the lower prices experienced in the fourth quarter of 2018 and first quarter of 2019.


Second quarter production was 463,136 carats recovered from the processing of 695,934 tonnes of ore at an attributable grade of 67 cpht. Tonnes processed and carats recoveries increased by 19% and 4% respectively compared to the first quarter mainly as a result of higher plant availability. Grade recovered decreased by 13% due to the mining of lower grade blocks as part of the mining sequence. Tonnes processed, grade and carats recovered increased by 24%, 68% and 107% year over year, due to the ramp up of underground operations and the improved mix of ore sent to the process plant.

During the quarter, process plant feed was derived from the Renard 2 underground mine (87%), the Renard 65 stockpiles (9%), and the Renard 3 underground mine (4%). Average daily processing rates in April (7,734 tonnes per day), May (7,320 tonnes per day) and June (7,899 tonnes per day) were all higher than the budgeted rate of 7,000 tonnes per day as a result of improvements in plant availability and utilization. The average ore tonnage hauled to surface from the underground mine was 6,813 tonnes per day during the second quarter, significantly above the design capacity of 6,000 tonnes per day.
