The breccia-hosted Olympic Dam iron oxide Cu-U-Au-Ag deposit is located 560 km NNW of Adelaide (-30.44°, 136.87°) in the Olympic copper-gold province in northern South Australia (SA). The Prominent Hill and Carrapateena Cu-Au-U deposits are 150 km NW and 100 km SE of Olympic Dam respectively. The total resource (measured, indicated and inferred at September 2016) is 10 400 Mt at 0.77% Cu, 250 ppm U3O8, 0.32 g/t Au and 1 g/t Ag (Table 1). The resource footprint at the top of the Mesoproterozoic basement (that is, the unconformity around 350 m depth) is approximately 6 × 4 × 0.8 km, but with localised occurrences of mineralisation to over 2 km depth. The altered and mineralised rock volume associated with the deposit has an overall areal extent exceeding 50 km2. Olympic Dam is the fifth largest copper, the largest reported uranium and one of the largest gold deposits in the world.
