Olympic Dam is on the eastern margin of the Gawler Craton and is one of the world’s most significant deposits of copper, gold, silver and uranium. The deposit is unconformably overlain by about 300 m of Neoproterozoic to Cambrian age, flat-lying sedimentary rocks of the Stuart Shelf. The deposit is hosted within the Olympic Dam Breccia Complex, occurring entirely within the Roxby Downs Granite.
Mineralisation is contained within a granite-hosted breccia complex. The principal copper-bearing minerals in the deposit are chalcopyrite, bornite and chalcocite, occurring as disseminated grains, veinlets and fragments with breccia zones. Gold typically occurs as extremely fine particles within and associated with the copper sulfide grains. Silver largely occurs in solid solution with the sulfide minerals.

|Resource estimates and production estimates|
Company released resource estimates and production statistics are available from the BHP Annual Report 2018 - refer to section 6.
The Olympic Dam Mine operates under the Roxby Downs (Indenture Ratification) Act 1982 and the Olympic Dam and Stuart Shelf Indenture (the Indenture) which is a Schedule to the Act.
BHP is proposing a significant increase of copper production at the Olympic Dam mine to up to 350,000 tonnes a year. The Minister for Energy and Mining and Minister for Planning have declared this proposal a major development under the Development Act 1993.
