Canadian diamond miner Stornoway Diamonds has produced 1.32 million carats in the 2018 financial year, missing its guidance of “at least 1.35 million carats” for the year, Mining Weekly reports.
President and CEO Patrick Godin said that 2018 was a “challenging year” for the company, as the ramp-up of underground production of the Renard 2 underground mine was “impacted by delays in equipment deliveries, a competitive labour market and the presence of more-than-expected low-grade mineralisation on the northern margin of the Renard 2 orebody”. However, the company’s third and fourth quarter production results “demonstrated significant improvements in grade and carat recoveries”. For 2019, Stornoway expects to produce between 1.8 million and 2.10 million carats.
As for sales, in 2018 Stornoway sold 1.04 million carats for gross proceeds of C$141 million ($106,362,645). In the fourth quarter, sales amounted to 253,929 carats, netting C$31 million (23,384,695).
