Understandable, someone at rio said the word porphyry when describing Winu, but its just not the right geological setting.
Here is a basic read on some deposit types in the area you might get something from

Nothing that will impact us, different deposit types have different exploration implications (e.g. different electromagnetic and magnetic signatures, geochemical patterns and alteration styles) but AZY, RIO, Newcrest and IGO + other explorers in the Paterson know all that and are searching for a variety of deposits.
