Slide 7: Pursuing the capital efficient tonne

·; Our focus has shifted from the marginal tonne to the capital efficient tonne

·; Debottlenecking opportunities have the potential to release significant capacity well beyond 220 mtpa (100% basis)

·; We will exercise the options with the lowest capital intensity and highest returns to unlock substantial value

Slide 10: Debottleneck and optimise the supply chain

·; Targeting the release of substantial capacity at low capital intensity

Slide 13: Port: deliver the capital efficient tonne

·; 5th car dumper installed end CY12

·; Optimised throughput potential 55-60 mtpa per dumper

·; 7th and 8th shiploaders recently installed at Nelson Point

·; Optimised throughput potential 35-40 mtpa per shiploader

·; Low cost opportunity to debottleneck the conveyor, stockyard and stacker-reclaimer system

Slide 14: Port: low cost debottlenecking of our conveyors and stockyards

·; Latent capacity in our car dumpers and shiploaders has been tested and proven

·; Complex interconnections are constraining the system

·; System capacity will rise significantly as we debottleneck our stockyards and conveyors

Slide 16: Rail: substantial upside in our existing dual track

·; Dual track can deliver more than 300 mtpa of capacity with modest investment

Slide 17: Mines: readily expandable

·; Mobile crushers can unlock 20 mtpa of capacity

·; Jimblebar built for expansion beyond 35 mtpa

·; One new mine required to achieve >300 mtpa
