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 100-110 ktpa Cu and 100-130 kozpa Au

CARRAPATEENA PROJECT CONCEPT

*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 2015.

HALF YEAR FINANCIAL RESULTS TO 30 JUNE 2013 INCOME STATEMENT

• Lower copper production and lower commodity prices are the primary drivers of Underlying NPAT loss.

• Significant focus on cost reduction, including contract and supplier renegotiation and review of operational and support roles

Mining costs reflect higher open pit mining activity and inclusion of Ankata costs, offset by higher deferral as a result of IFRIC 20

Decrease in exploration due to reduction at Prominent Hill

Decrease in corporate and support costs, offset by inclusion of insurance receipt in 2012

After tax asset write down

Lower production and commodity prices

Increased depreciation due to deferred waste and Ankata

MARKET DRIVEN CONTROLLABLE

Reduction in copper and gold pricing, realised pricing will be in-line with LME copper price

Lower grades mined from open pit resulting in lower production and sales

11% decrease in A$/US$ over H1 2013

Increased waste deferral and positive stock adjustment offset by higher depreciation

Higher open pit mining activity offset by reduced exploration spend, other operating costs were flat

Inclusion of new underground operation (Ankata)

2012 included gain on sale of Cambodian assets
