Rough diamond production increased by eight per cent to 7.4 million carats, reflecting the contribution of Gahcho Kué in Canada, as well as increases in response to improved trading conditions.
Production decreased marginally to 5.2 million carats. At Jwaneng, production decreased eight per cent due to expected lower grades, partly offset by Orapa, which increased five per cent due to higher grades.
Production increased 19 per cent to 1.1 million carats, largely as a result of higher grades at Venetia.
Production increased six per cent to 472,000 carats due to marginally higher grade at Namdeb.
Production increased significantly to 631,000 carats due to the contribution of Gahcho Kué, which reached commercial production on 2 March 2017.
