Reserve Estimation – Mt Stuart Joint Venture and the West Pilbara Iron Ore Project ‐ Stage 1 Development

ORElogy, an independent mine planning consultancy, has completed a Reserve estimate for the Mt Stuart Joint Venture based on the eight Channel Iron Deposits within the WPIOP – Stage 1 development area. The MSJV Ore Reserve estimate is based on the Catho Well CID and is a subset of the total WPIOP – Stage 1 Ore Reserve.

The Ore Reserve has been prepared in accordance with the Australasian JORC 2004 (Joint Ore Reserves Committee) code. The Ore Reserve has been classified as Proven and Probable based on the Measured and Indicated Mineral Resource classifications respectively. Inferred Mineral Resources have not been included in the Ore Reserve estimation.

The Ore Reserve estimate attributable to the MSJV is detailed in Table 1

As previously stated the Ore Reserve has been estimated by incorporating all deposits within the WPIOP – Stage 1 development area in order to achieve the targeted blended product grade specifications. The attributable MSJV Ore Reserve represents 16% of the total WPIOP – Stage 1 Proven and Probable Reserve totaling 445 Mt. The MSJV Ore Reserve has been derived from the Catho Well CID.

The WPIOP – Stage 1 Ore Reserve is reported as two products;

• Product 1 ‐ representing the main production stream maintaining an average 57.1% Fe throughout the life of the WPIOP ‐ Stage 1 mining operations, and;

• Product 2 ‐ a lower grade product stockpiled throughout the mining operation and shipped following the completion of Product 1 Ore sales based on an annual average product grade of 55% Fe.

Ore derived from the MSJV contributes to the main product stream (Product 1). No material has been scheduled for the lower grade Product 2 from the Catho Well deposit. A two product stream has been modelled for the broader WPIOP – Stage 1 in order to maximise the Ore Reserve.

The MSJV Ore Reserve has been reported as the Ore produced and contributing to the production of the WPIOP – Stage 1 blended products. Variation between the MSJV Ore Reserve grades reported above and the Product 1 specification has resulted from the separation of Ore contributed by the Red Hill (Jewel, Cochrane, Cardo Bore North, Cardo Bore East, Upper Cane, Kens Bore (partial), Catho Well (partial) and Trinity Bore CID) and API Joint Venture’s (Kens Bore East CID).

Ore Reserve Parameters

The Ore Reserve estimate in Table 1 has taken into account the following parameters:

• Updated resource block models for all deposits within the WPIOP – Stage 1 development area. These resource models utilise the most up‐to‐date information provided by API to ORElogy;

• Mining Study version 5 information, which includes current mining methods, costs, recovery and geotechnical information;

• A review of all pit optimisations using the above information;

• Re‐designed ultimate pits for each resource;

• Mineable reserves using only measured and indicated resources; and

• A life‐of‐mine schedule that meets the product specification requirements in a practical and achievable manner, throughout the life of the operation.

Pit Optimisation, Mine Design and Scheduling

The Ore Reserve reported is within pit designs based on shell selection from Whittle 4X pit optimisations carried out on Measured and Indicated Mineral Resources only. The resource models used for the pit optimisations were prepared by Golder Associates and reported in October 2010 (ASX release 29 October 2010). The regularised block size used for all models was 25m x 25m x 4m reflecting the scale of mining to be used. Mining models were created using MineSight software. The mining models were exported to Whittle 4X for pit optimisation and subsequent pit shell selection.

The pit design and optimisation criteria used are detailed in Tables 2 and 3 and are based on appropriate studies completed in preparation of a WPIOP feasibility study. The revenues and costs may differ as between the different participants in the joint ventures that make‐up the WPIOP.

The pit optimisation incorporated an ore loss factor of 9.5%. This approach centres on maintaining product quality and the preference to account for higher ore loss rather than suffer dilution that would negatively impact product quality.

The optimal shells generated were used as the base for pit and stage design. Mine scheduling was undertaken using evORElution scheduling software, with the aim to confirm the ability to produce 30Mtpa of primary product from the pit designs. The scheduling is based on annual reporting periods and the following scheduling philosophy:

3

• The WPIOP – Stage 1 is split into 3 distinct mining areas that is, north (Cochrane and Jewel), central (Kens Bore, Cardo Bore North, Cardo Bore East and Upper Cane) and south (Trinity Bore and Catho Well);

• Ore is mined from each of the northern and southern areas at the average grade of the combined resources in each region. Ore from the central area is mined at such a rate and from the appropriate locations to ensure a consistent overall grade is maintained during the course of each year and over the life of the mine;

• Once mining in all areas is concluded, the rehandle of stockpiled second product will commence;

• All stockpiled ores will be transported to the Central Processing Facility.

The updated resource estimates used in determining the Ore Reserve has resulted in a low waste to ore ratio. The final pit designs, for all deposits, produced a waste to ore strip ration of 1.13:1 for the WPIOP – Stage 1 mine development

At this stage, no decisions have been taken by the Participants in the MSJV as to the scope of the development of the Catho Well CID. The Feasibility Study for the MSJV Project will progress with the incorporation of this maiden Reserve and the underlying mine schedule, as well as additional work undertaken. The Feasibility Study, scheduled for completion early 2011, will include a scenario which assumes ownership of Cullen’s run‐of‐mine ore will be transferred at the Mine Gate.
