First off, the core length was closer to 5 m than 4.   To suggest that they drilled +100 metres into the ground and went thru 5 m of mineralization that is 1/2 to 1 m in width is ludicrous. also to suggest there is 1 tonne to the cubic metre is false. Using very general terms and measures, that 5 m core would have to have cubic measurements of apprximately 13 m in each other direction to amount to 2000 tonnes of ore. Nothing out of the ordinary there, is there.
