* Olympic Dam is the world’s fourth-largest copper deposit, the largest known uranium deposit and the fifth-largest gold deposit.

* Olympic Dam produced 194,000 tonnes of copper and 4,000 tonnes of uranium in the year ended June 30, 2009.

* Located 560 km (348 miles) north of the south Australian city of Adelaide, it is Australia’s largest underground mine.

* The site comprises ore zones spread over several square km and ranging in depth from 350 metres to 1 km.


* Copper concentrate produced from the mine is fed to a smelter at the site that produces blister copper before being further refined into copper cathodes. The slimes from this process are treated separately to recover gold and silver.


* BHP plans to expand the mine progressively over 11 years. The expansion project is still awaiting government approvals and a final investment decision.

* Expansion would take annual production levels to:
