Actions implemented to improve throughput performance

• Blasting design to reduce feed size to SAG mill – in cooperation with Orica. Done.

• Increased SAG mill discharge openings to evacuate pebbles to pebble crushing circuit. Doneo Opened to 75mm in Sept 2010o Opened to 85mm in Feb 2011

• Pre-crushing of ore using supergene crusher to reduce feed size to SAG mill. Doneo Commenced December 2010o Average 10,000 tpd

15

Further short term actions to enhance throughput - 2011

16

• Install jaw-crusher to increase pre-crush tonnage (~2000 tpd). Done

• Install permanent 2-stage crushing to increase pre-crush tonnage (up to 20,000 tpd). In Progress.

• Increase power to SAG mill by upgrading cooling system (up to 10%). Done

• Expand plant with SAG mill #2 and associated plant additions – study proposal on going. In Progress
