volume of the stockpilejust baseing my predictions off of the stockpile picture and shooting short on everything, i think we could be looking at 56000cubic meters of stockpile. in theory this stockpile said to be located in a revine so this is my formula (Volume triangular prisum=.5BHL)(V=.5 x 50m x 15m x 150m) gives you 56250m3. i undershot the weight of a cubic meter of gravel (1.68tonnes/cubic meter)
(56250 x 1.68=94500tonnes) now i think we average at least 1g per tonne giving you 94500g of gold. that gives you 3048ounces(94500/31=3048). this is just my predictions, and know i shot short on all my numbers. i believe there is more than what my numbers come out to, im just trying to give a reasonable answer.
