Agree, Olympic Dam and Prominent Hill are IOCG, and I dont think AVB have seriously looked at the "G" of the "IOCG" yet.
Two large IOCG targets in the area.
The supergene areas may not be that big, but there could be a number of them. The main IOCG targets could be absoluetly massive i.e. hundres of millions of tonnes (at low grades though)
