I was using Excel and a circular method (as opposed to the normally used polygon method) to estimate the resource. So for each successful drill hole; I applied a radius of 50 meters (which is around half way between drill holes); then I multiplied that by the depth from the drill results; worked out the average grade for each drill; and applied a tonnage of 3t per cubic meter for dolerite.

Anyway; my resource estimation may be very conservative. I will keep BBX on watch and I hope to see a JORC estimation in the not too distant future.
