Aim-listed Botswana Diamonds has refined its Vutomi joint venture’s estimate for the grade at its Frischgewaagt project, in South Africa. This followed the inclusion of the results of the bulk sample and an update to the estimation analysis technique, which indicated a medium grade of 78 carats per hundred tonnes (cpht) in a range of 64 to 110 cpht at a bottom cut off of +1 mm.
