Abstract

Iron oxide-copper-gold (IOCG) mineral systems occur globally and range in age from Archean to Mesozoic or younger. An assessment for IOCG mineral system potential has been undertaken in the southern Arunta Region, incorporating the southern Aileron and northern Warumpi provinces. The assessment has been undertaken in a GIS-based environment using a mineral systems approach. This approach recognises four key system components: (1) sources of metals and fluids, (2) fluid-flow drivers, (3) fluid-flow pathways and architecture, and (4) depositional sites and mechanisms. For each of these key system components, mappable criteria were developed as proxies for mineralising processes in order to identify potential IOCG mineral systems. The locations of known deposits and prospects were not used for generating the assessment of IOCG potential. However, they are used as a validation of the results. The assessment largely reproduces the locations of known IOCG-style mineralisation, and predicts additional potential in a number of other areas, many of which are obscured by recent sedimentary cover. An approximately east-west-trending belt of broad IOCG potential has been identified, along with local regions of high potential where favourable criteria occur.
