First rail shipment of Prominent Hill
concentrates to Darwin

OZ Minerals has achieved an important milestone in the establishment of its Prominent Hill coppergold
mine in South Australia, with the first rail delivery of concentrate to the Port of Darwin. The
shipment was dispatched from the Wirrida rail siding, which is located approximately 115 kilometres
west of Prominent Hill. The Company expects to deliver approximately 600 tonnes of concentrate
per day, six days per week to the port.

From the Port of Darwin Prominent Hill copper concentrates will be shipped to smelters across Asia.
The first shipment from Darwin is expected to be made in late April. Concentrates also continue to
be delivered via road to local customers.
“Since first production in late February, the ramp up of the processing plant has progressed very
well, the operation has now reached a production rate of around 80% and, as planned, is expected
to reach its nameplate rate by the end of the year,” said OZ Minerals Managing Director and CEO
Andrew Michelmore.

Prominent Hill concentrates are characterised by their high copper grades and low arsenic
content. The grade of Prominent Hill concentrates has consistently been more than 50% copper
with all other elements well within normal contract specifications.
