Production for the year was 133,050 tonnes compared to 103,506, a year earlier.
It said its average grade was flat at 3.1 carats per hundred tonnes (cpht), while the value per carat averaged $341 in the quarter from the previous quarter’s $362.
“Our increased production in the quarter and in 2018 is encouraging however we are not yet where we would like to be,” said BlueRock chief executive Adam Waugh.
“Operations are moving into an exciting phase and the knowledge built up at Kareevlei will be important in making the correct decisions for the future.”
