The greater Alteration Ridge area was selected for further 3D modelling on the basis that: It hosts a cluster of P-1/P-2 surface geophysical targets; It hosts several known areas of mineralisation, including the recently discovered Cuncayoc Copper Prospect; It is adjacent to the rhyolite volcanic dome and In broad terms, it is believed to be the centre/nearcentre of a large intermediate sulphidation (IS) epithermal system.
The giant ice-mountain Ahuna Mons is a volcanic dome constructed by repeated eruptions of freezing salty water.
