- BlueRock Diamonds said the crushing circuit at its the Kareevlei diamond mine in South Africa was now processing at or above the company's target production level of around 80 tonnes an hour.

The improvement came after the installation of a second cone crusher and the implementation of optimisation initiatives, the company said.

A fault was discovered in the crusher in June, which led to processing being stopped for around 10 days.

Whilst the fault was being rectified, a rented crusher was installed on site at Kareevlei at [modest additional' cost.

BlueRock's original cone crusher was now refurbished and operating in tandem with the rented crusher, thus increasing the throughput capacity in the secondary crushing process.

'The company looks forward to providing an update on the third quarter's production in early October 2018,' BlueRock said. Story provided by
