CONSOLIDATED INCOME STATEMENT

• Lower copper pricing and decreased gold production reduced revenue compared to 2011. • Higher mining costs due to increased material movement and depth of pit. • Sale of Cambodian assets to Renaissance Minerals Limited completed in H1 2012.

Includes raw materials, consumables, direct employee costs, movements in inventory,

freight and royalties.

Prominent Hill, Carrapateena and foreign exploration.

Corporate and site administration (ex. Employee costs).

Lower tax expense due to lower taxable income.

Lower average Copper price (14% down from 2011).

Lower ore mined reduced depreciation.
