73koz increase in Resources compared to June 2012
==> picture [678 x 307] intentionally omitted <==
Notes:
Data is reported to significant figures and differences may occur due to rounding Mineral Resources are inclusive of Ore Reserves
Cracow Mineral Resources have been reported above a cut-off grade of 2.3 g/t gold
Cracow was estimated using Ordinary Kriging into blocks with a range of dimensions optimised to the characteristics and geometry of each deposit Competent Person: Shane Pike, a member of the Australasian Institute of Mining and Metallurgy

Improvements under Evolution
==> picture [109 x 77] intentionally omitted <==
-
Current investment in underground development to provide production flexibility and ensure long term predictability
-
Changing to owner mining 1 July 2013 – cost benefit of about A$50/oz expected
-
New equipment – improved efficiency
-
Two new Atlas 6020 trucks, two new Jumbos, two new Loaders
-
Opportunity to reduce costs and improve efficiency
-
Plant numbers reduced
