These paragraph is very interesting.
No LDD sampling has been performed below a depth of 150m, however core holes have been drilled down to depths of 250m and the results thereof indicate primary kimberlite and continuity to depth.
It's a good probability they have more tonnage and diamond there and more year in production.
