With the little knowledge I have on drilling for minerals my take on it is that they have only done very shallow drilling around established tracks.

This I would imagine gives them a broader idea of what lies beneath relatively cheaply rather than clearing tracks into the bush.

for them to invest as much as the did should give you confidence this is more than just a punt
