- BlueRock Diamonds downgraded its annual production guidance due to plant reliability problems at its Kareevlei mine in South Africa.

Output for the full year through December was now expected to be 200,000 tonnes, down from already lowered guidance of 220,000, the company said.

Production in the third quarter reached 63,621 tonnes, while year-to-date production was up 28% on-year to 133,050 tonnes.

'Our increased production in the quarter and in 2018 is encouraging however we are not yet where we would like to be,' chief executive Adam Waugh said.

'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.'
