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.

2013 EXPLORATION COMMITMENT

• Total exploration budget for 2013: $58 million.

• Prominent Hill exploration $25 million of which $17 million is expected to be capitalised resource drilling in the Malu underground.

• Further regional exploration drilling and geophysics at Khamsin and Fremantle Doctor prospects.

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.

OBJECTIVE SHAREHOLDER RETURNS

OZ MINERALS • PAGE 24

CONCLUSION

• Prominent Hill delivers another consistent production year with 101,737t of copper and 140,746oz of gold at a C1 Cost of US120c/lb.

• Resource drilling in the Ankata underground increases its life by two years – further resource drilling sees high grade intercepts.

• Mine development commenced on the Malu underground.
