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. Done Opened to 75mm in Sept 2010 o Opened to 85mm in Feb 2011 o • Pre-crushing of ore using supergene crusher to reduce feed size to SAG mill. Done Commenced December 2010 o Average 10,000 tpd o 15

Further short term actions to enhance throughput - 2011 • 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 16
