They need to double up on the contained copper vs the current inferred JORC. Which is within reach if they can locate incremental high grade supergene ore and the sulphide zone.

Scientifically, for the supergene zone to exist (which we know exist in high grade based on mine record), there has to be massive sulphide hidden somewhere down there. Supergene cant exist without massive sulphide as supergene is a product of weathering process of the sulphide zone. So its a matter of time before the sulphide is discovered and that will add bulk tonnage to the contained copper.
