Approval process

The proposed Olympic Dam Expansion

An agreement has been signed to amend the existing Roxby Downs (Indenture Ratification) Act 1982 to enable the construction and operation of the multi-billion dollar Olympic Dam expansion project.

A Bill to ratify the amendments to the Olympic Dam and Stuart Shelf Indenture was approved by both Houses of Parliament in November 2011.

Frequently asked questions about the Indenture

The legislation required that BHP Billiton commence the project by 15 December 2012 otherwise the amendments would lapse.

In August 2012 BHP Billiton announced the deferment of the project and its intention to consult with the Government on adopting an alternative, less capital-intensive design for the open pit expansion.

The Government subsequently granted an extension of the period in which BHP Billiton could trigger the amended Indenture, with that end-date now being October 2016.
