PROMINENT HILL FACTS
• A workforce of approximately 1,200 – this includes
contractors.
• Growth due to underground.
• We have a local workforce – 80% of our people
are from South Australia.
• Open Pit – Thiess.
• Underground– Byrnecut Mining.
• Village Services – Sodexo.
• Charter Flight services from Adelaide,
Port Augusta, APY Lands and Melbourne.
• Daily bus service from Coober Pedy.
• Site Facilities – 1200 rooms with en-suites,
swimming pool, sports courts and gymnasium.
• Regular family days to bring family members to
site to experience life at Prominent Hill.

PROMINENT HILL PRODUCTION
Product: High grade (~50% Cu), high quality, copper concentrate.
Production (2011): 107,744t contained copper, 160,007oz gold.
Production Guidance (2012): Contained copper 100,000t to 110,000t
Contained gold 130,000oz to 150,000oz
Mine and Plant: Open pit mine, crush, grind, flotation.
Estimated C1 costs 2012: US$1.00-US$1.10/lb. (increased primarily as a result of underground mining)
OZ MINERALS • PAGE 20
UNDERGROUND DEVELOPMENT
• Underground achieved first production from
stoping Q1 2012.
• The underground will contribute 25,000
tonnes of copper and 12,000 ounces of gold
allowing current levels of production to be
maintained.
• The access decline, just over one kilometre
long, reached the Ankata orebody in mid
2011.
• 1.2Mt per year expected in 2012-2015.
• Average grade range for 2012 to be
2.3 - 2.8% copper.
OZ MINERALS • PAGE 21
PROMINENT HILL UNDERGROUND DEVELOPMENT
PROMINENT HILL LONG SECTION East West
• Exploration decline advanced to 445 metres, expected to be completed in Q4 2012.
• Drilling from the exploration decline under the Malu pit expected in H2 2012.
OZ MINERALS • PAGE 22
TRANSPORT OF PROMINENT HILL COPPER CONCENTRATES
• Convenient access to the Adelaide to
Darwin railway.
• Shipments of concentrate from
Adelaide and Darwin ports.
• Rotainer handling system uses
specially designed containers.
• Enables us to bypass a concentrates
shed and traditional loading facilities.
• First copper concentrate shipment
using handling system was exported
from Adelaide in January 2012.
OZ MINERALS • PAGE 23
CARRAPATEENA WORKING WITH SOUTH AUSTRALIA
• A staged approach to
permitting will be required to
reach 2017/2018
development date.
• Continuous engagement
with DMITRE to streamline
permitting process.
• Good support from South
Australian government.
