RAPAPORT... Stornoway Diamond Corporation increased its net loss in2018 amid delays in the transition of its Renard mine in Canada and therecovery of lower-than-expected grades. The deficit widened to CAD 329.4 million ($246.8 million),compared with a loss of CAD 114.2 million ($85.6 million) the previous year,the miner said last week. The delays held back operations as Stornoway moved from open-pit to underground mining, and affected the average volume of diamonds the miner was able to retrieve from ore during the transition, Stornoway CEO Patrick Godin said. Weak pricing also created challenges. "The low diamond-pricing environment in which Renard beganoperating persisted in 2018," Godin added. An impairment charge - a devaluation of the company's assets -of CAD $83.2 million ($62.3 million), as well as a deferred income-tax paymentof CAD 77.4 million ($58 million), also contributed to the loss. Revenue for the year dropped 16% to CAD 165.5 million ($124million), with sales volume down 29% to 1.2 million carats. Annual productionfell 19% to $1.3 million, missing the bottom end of the company's guidancerange. A technical problem at the miner's processing plant caused it to performbelow capacity, the company said. Stornoway sold 1 million run-of-mine carats for CAD 141million ($105.6 million) in 2018, at an average price of $105 per carat. Itsold an additional 164,322 carats of supplemental diamonds for CAD 3.5 million($2.6 million), at an average price of $16 per carat. In the fourth quarter, the company reported a loss of CAD244.9 million ($183.5 million), versus a loss of CAD 118.4 million ($88.7million) a year earlier. Revenue fell 58% to CAD 23.3 million ($17.4 million). Stornoway expects output to rise to between 1.8 million and2.1 million carats in 2019, as it moves to a higher-grade area of the mine, itsaid in January.
