Ann: Vertical Continuity of Cu Mineralisation Confirmed at Ngami, page-47

Some very basic calculations on potential tonnage " discovered " to date.

4 km strike
width 10 m
depth 250 m

That gives 4000 m x 250m x 10 m = 10,000,000 cubic meters

The density of copper ore is ~2.3 grams per cubic cm therefore 1 cubic meter weighs @2.3 tonnes

So very rough back of the envelop calculations have tonnage discovered to date at ~23 million tonnes

With the ore body being open along strike in both directions, and at depth, the chances of of significantly larger resource number being put up high. If the CU grade is the typical present in the offset deposits north east and south west being ~ 1.5 -2.5 % with silver credits, then the implications are pretty obvious.
