Ann: Mbelele-2 results point to prolific new helium province, page-297

An important question is ......... what is the volume of gas per unit volume of fluid that is is exsolved as the fluid rises to surface ( ie becomes de-pressurized). I assume this information would have become known with the sample taken from Mbele 2 Once this figure is established and the total volume of the geological holding formation the fluid is defined ( or predicted) then an estimate can be made of the total available volume of exsolved gas (of which 2-3% is helium). Maybe management have already done a back of envelope calculation.
