Interestingly on the map provided in todays Ann, ... the distance between the blue dots (may 2016 samples) seems to be 5km ... So one can "speculate" that the strike is at least 5km long?? ... It would be pretty easy to achieve 3mt "if" the mineralisation were consistent over that distance
So mineralised envelope would need to be say 5m true width, 0-50m deep, 5km long and say have a SG (Specific Gravity) of 2.8
