SUMMARY

• Continued focus on improvements in safety performance.

• Completion of remediation of the south wall overburden slip ahead of schedule.

• Improved production expected in the second half with copper production guidance maintained.

• Lower first half production led to higher C1 costs, however, trend improving for unit mining costs. Annual C1 cost guidance maintained.

• Carrapateena pre-feasibility study continues, due for completion H1 2014.

• Further excellent results from the Khamsin copper discovery near Carrapateena.

• Ore mined was lower due to overburden slip remediation work.

• Lower grade ore mined from Malu open pit and Ankata in line with life of mine plan. Grades to increase in second half.

• Material movement higher in Q2 with additional equipment and improved productivity. Planned to increase further in H2.

• Milled grade planned to increase in H2.

• Planned copper production to be higher in H2 (particularly the last quarter.)

• Ankata continues to perform well and improve each quarter.

* Figures slightly different to previously reported due to final adjustments
