Ann: Satrokala Iron Ore Project First Exploratory Drilling Update, page-10

Sorry, pasted the wrong bit...

"Iron oxide copper gold (IOCG) deposits are considered to be metasomatic expressions of large crustal-scale alteration events driven by intrusive activity. The deposit type was first recognised by discovery and study of the supergiant Olympic Dam copper-gold-uranium deposit (Olympic Dam mine), and South American examples."

I have also had a cursory look at a couple of other pages, so don't put too much stock in this speculation...

From the "Geology" section.

"Gold mineralisation is typically associated the pyrite & pyrrhotite replacement of magnetite in the banded iron. High grade ore shoots are developed along the intersection of the BIF and a swarm of northeast trending faults, colloquially referred to as Boogardie Breaks.

Significant gold mineralisation is also found in porphyritic felsic units of the Boogardie Basin. Mineralisation generally occurs as a stockwork style of sericite-silica-pyrite veining and alteration within felsic porphyry units intruded into ultramafic flow sequences. Gold mineralisation tends to occur along felsic margins adjacent to the ultramafic contact. The Cosmos area consists of this style."
