Previous classification of gold deposits in the Gawler Craton grouped occurrences into either Archean orogenic deposits, or intrusion-related deposits associated with the Hiltaba Suite intrusive event (Central Gawler Gold Province). In this study, the gold deposits and occurrences of the Gawler Craton are classified using a mineral system methodology. Four mineral systems are defined, ranging in time from the Archean to the Mesoproterozoic. The regional extent of these mineral systems is shown to possibly extend way beyond the currently known distribution of mineralisation. In addition, at least two major magmatic events (which formed the Saint Peter Suite and the Tunkillia Suite) are recognised as having potential to be associated with significant gold mineralisation.
