This talk outlines three key regional geological features considered to be essential for development of major iron oxide copper-gold systems in the Gawler Craton. They are as follows: 1. A plumbing system, comprising crustal-scale structures that developed during Palaeoproterozoic orogenesis along the margins of the Archaean core of the Gawler Craton. 2. Coeval timing of IOCG hydrothermal activity and Hiltaba-GRV magmatism at ~1575-1595 Ma. Anomalous high heat input to the crust, resulting in particular igneous rock compositions and high-temperature IOCG alteration at ~1575-1595 Ma
