matrix, I am certain you would want my opinion too.
But you did not ask. The work is professionally done and the geo appears quite competent. However they only gave him 2 pieces of core so he is in no position to conclude anything substantive about a long core section that he did not see. To me the report is a step above a 'skunk-out'. It LOOKS LIKE they have a kimberLITIC intersection. The geo did not come flat out and say "THIS IS KIMBERLITE".
