22 CARRAPATEENA LOCATION Carrapateena is another large iron oxide copper gold deposit, similar to Prominent Hill, located 300km to its southeast. OZ Minerals is undertaking a pre-feasibility study on the project. OZ MINERALS PAGE 22

23 CARRAPATEENA A SECOND COPPER GOLD DEPOSIT IN SOUTH AUSTRALIA Acquired in May 2011 for US$250 million. Tenement package over 3,620sq km, including newly acquired Straits Tenements. Large Iron Oxide Copper Gold deposit similar to Prominent Hill. The current Indicated and Inferred Resources of 292Mt at 1.29% Cu, 0.48g/t Au (0.7% Cu cut off).

25 CARRAPATEENA PROJECT CONCEPT The Scenario below is conceptual only and is based on a scoping study* which has been undertaken and which examines the potential for a large scale long life copper operation. Mining Potential multiple lift block cave mine with production rate of 10-15Mtpa, (potential for some sub-level open stoping). Dual declines for access and production developed by tunnel boring machine Possible 20+ years mine life Processing Production of a high grade copper concentrate at approximately 90% copper recovery and 70% gold recovery Potential production of ktpa Cu and kozpa Au *A Scoping Study provides direction for future studies but has low accuracy. Further drilling, geotechnical, metallurgical and study work are required to demonstrate the viability of this project before a decision to mine can be made with any certainty. This is expected to be after a pre-feasibility and feasibility study are complete in OZ MINERALS PAGE 25
