Abstract
Thirteen diamonds were recovered from a 171.6 kg sample of the DR042 kimberlite with the two largest stones greater than 0.15 mm in two dimensions. A 278.7 kg sample from the DR034 kimberlite produced two diamonds and one diamond was recovered from a 66.9 kg of the DR093 kimberlite. No diamonds were recovered from a 109.4 kg sample of the DR036 kimberlite. Finally, a 411.8 kg sample from a previously untested portion of the 11 hectare Iceberg kimberlite yielded 10 diamonds, with the largest stone exceeding 0.3 mm in two dimensions.
