Olympic Dam - Expansion
The Olympic Dam Expansion was declared as a Major development in November 2008. The development involves the expansion of the existing Olympic Dam open cut mine near Roxby Downs. The expansion will increase production by up to 1 million tonnes per annum or copper and associated products.
The expansion will also include a new borefield for water supply, upgraded electricity and transport infrastructure and an expansion of the Roxby Downs township. Significant waste rock storage areas, expanded evaporation basins and a new desalination plant at Port Bonython are also proposed.
