BlueRock improves diamond recovery since upgrades

Aim-listed BlueRock Diamonds on Thursday reported that since it restarted operations at its Kareevlei mine, recovered grade has been improving from initially 1.53 carats per hundred tonnes (cpht) to the most recent results of 3.02 cpht. The company late last year embarked on a thorough overhaul of the main components of the processing plant.
