Aim-listed BlueRock Diamonds notes in an operational and corporate activity that the results of the two-month test to determine the realistic capacity of the Kareevlei plant at the diamond mine in South Africa, which started in mid-October and was carried out with the assistance of mining and processing specialists, confirmed that production of just below 90 000 t a month is achievable, in line with previous guidance. It adds that, of greater importance, has been the confirmation that the plant was not affected to any significant extent by wet weather experienced in October and November.
