OZ MINERALS • PAGE 8
2013 GUIDANCE
• Copper production will be below 2012 levels due to the geometry of the ore resource in relation to waste material, restricting copper ore mined.
• Copper production will be weighted towards the second half of 2013 as access to copper ore increases in combination with higher copper grades mined from Ankata.
• Gold production guidance is maintained at the same level as 2012.

• The 2012 Indicated and Inferred Resources of 292Mt represent a 43% increase over the 2011 resource at a 0.7% Cu cut-off.
• Much of the 2011 Exploration Target area has been converted to Mineral Resources in the 2012.
• Infill exploration drilling program has better defined the higher grade bornite zones - now one bornite zone.
• Deeper infill exploration drilling has led to an extension of the Resource at depth.
* These wireframes show the interpreted limits of the Chalcopyrite envelope and Bornite zones respectively. These domains contain almost the entire resource. Intervals calculated using a 0.3% Cu cut-off grade.

CARRAPATEENA EXPLORATION DECLINE - UPDATE • OZ Minerals purchases a
remanufactured Tunnel Boring Machine (TBM) to fast track development of the exploration decline at Carrapateena.
• Expected cost of TBM including mobilisation $12-15 million - to be commissioned in late 2013.
• Expected development rates between 350-550 metres per month.
• Expected time to reach geotechnical level ~625 metres below surface approximately 12 months ahead of traditional drill and blast.
• Exploration decline development costs $100-110 million.

STRATEGY REAFFIRMATION Strategy has five key elements with base of zero harm:
1. Focus on copper.
2. Maximise potential of assets.
3. Build a project pipeline.
4. Invest in exploration.
5. Disciplined capital management.
Progress since 2009
• Prominent Hill consistent performance with developing underground future.
• Extensive exploration at Prominent Hill – Ankata in production, Malu UG being developed.
• Carrapateena acquisition, exploration & evaluation directed at development of long-term copper operation.
• Capital management: capital return $389M, share buyback $200M, with dividends $445M.
• Highly disciplined business development activity – shareholder value protected.
