Following decisions in August to investigate an alternative, less capital-intensive design for the Olympic Dam open-pit expansion, BHP will consolidate the management of the next phase of studies for the open-pit expansion, align with the company’s cost control strategy in the current economic environment, and position Olympic Dam to support BHP Billiton’s long term copper strategy.

Darryl Cuzzubbo will continue as asset president of Olympic Dam, reporting to Peter Beaven, president base metals, for all operational matters. In addition, Cuzzubbo will assume a further role of president South Australia reporting directly to Chief Executive Non Ferrous Andrew Mackenzie, for matters relating to the South Australian Government. He will also have responsibility for BHP Billiton’s ongoing participation in the uranium industry globally. The transition is expected to be completed by the end of March 2013.
