"Adding the extra tonnage at depths at 150m(where ore is un-oxidised)to the oxidised ore above 25m would raise the overall % to approx an average of 1%. This would make Gabanintha the richest vanadium deposit in Australia".
"Low cost open pit mining with minimal overburden of 3m to 8m".
"Mine life in excess of 50 years."
PMA V2O5 is about 0.47%
