1.1.2 Project Development

    Fourth shed at Esperance complete.

    Railway sidings project complete.

    Ore wagon delivery program continues. Last wagon delivery by April.

    Significant skills shortages has continued to delay completion of crushing and screening facilities expansion. Coupled with below plan rail movements during the last quarter 2005, production and sales are expected at a 6mtpa rate during the first quarter 2006.

1.1.3. Marketing

The market for fines remains tight, driven by increasing hot metal production in China. Price negotiations have resumed in Japan and Europe.

1.3. Exploration

Summary

The Koolyanobbing and Mt Finnerty project areas have been the primary focus of exploration activity during the quarter. At the Koolyanobbing project area, infill and step-out reverse circulation drilling comprised a total of 89 drill holes for 6,521 meters during the reporting period. At the Mt Finnerty project area, reconnaissance mapping and rock chip sampling was conducted over the northern and central portions of the joint venture tenements.

Koolyanobbing Project Area

The following table provides distribution details of the reverse circulation drilling conducted during the 4th quarter, 2005:

                         
Range   Prospect/Deposit   # of Holes   Meters
Koolyanobbing
  C, F North     61       4583  
Mt Jackson
    J4       6       450  
Windarling
    W4, W5, W8       20       1488  
Total
            87       6521  

    The drilling at the C and F North deposits on the Koolyanobbing Range target extensions to the present reported resources. Limited assays results for the F North drilling were available by the end of the reporting period. The F North mineralization consists of narrow discontinuous lenses of goethite-hematite. Best F North assay results for the reporting period consists of 23 meters @ 59.08% Fe, 0.075% P, 0.040% S, 1.30% Al2O3 and 4.31% SiO2 from surface in drill hole KFRC260.

    The drilling at the J4 prospect was largely infill to previous broad spaced (+150 meter) reconnaissance drill traverses. The present drilling has generally confirmed the presence of broad zones of Fe enrichment with only patches of mineralisation exceeding 58% Fe intersected.

    The Windarling drilling conducted during the reporting period consisted of testing isolated pockets of mineralization satellite to the present reported resources. Drilling at W4 tested a lens of mineralisation mapped west of the main W4 Deposit. Assay results received during the quarter included drilling completed in the previous reporting period that tested strike extension at the W1 deposit. Best Windarling results for the reporting period include:

    91m @ 61.76% Fe, 0.145% P, 0.019% S, 0.28% Al2O3 and 2.82% SiO2 from 59m in drill hole W1RC062,

    19m @ 62.57% Fe, 0.094% P, 0.089% S, 2.14% Al2O3 and 3.92% SiO2 from 19m in drill hole W1RC065,

    10m @ 65.19% Fe, 0.085% P, 0.078% S, 1.69% Al2O3 and 1.50% SiO2 from 7m and 15m @ 62.37% Fe, 0.059% P, 0.222% S, 3.38% Al2O3 and 3.52% SiO2 from 25m in drill hole W1RC068,

    22m @ 61.01% Fe, 0.142% P, 0.106% S, 1.86% Al2O3 and 2.82% SiO2 from 12m in drill hole W4RC081,

    21m @ 60.11% Fe, 0.183% P, 0.052% S, 1.98% Al2O3 and 2.54% SiO2 from 53m and 20m @ 62.72% Fe, 0.395% P, 0.010% S, 0.65% Al2O3 and 1.39% SiO2 from 108m in drill hole W4RC082.

Updates to the W1 and W4 geologic models and resource estimates incorporating the new drilling results are being pursued.

Golder Associates were commissioned to complete re-modelling of the Mt Jackson J1 Deposit subsequent to a major infill reverse circulation drill program in 2005. The new J1 resource model incorporates a total of 15 mineralization domains over the +2 kilometre deposit strike length. These mineralization domains are separated into 3 fault-separated blocks. A comparison of the resulting 2005 in-situ resource estimate and previous 2002 estimate is presented in the following table:

Mt. Finnerty Project Area

The Mt Finnerty project area is located 65 kilometres east of the Koolyanobbing Range and is covered by an iron ore joint venture agreement with Reed Resources executed in the 3rd quarter 2005. The geology of the project area consists of the north-westerly trending Watt Hills greenstone belt containing lenses of variably mineralized and lateritised banded iron formation over a 30 kilometre strike length. During the reporting period reconnaissance mapping and rock chip sampling was conducted over the northern 20 kilometres of the project area.

Although individual rock chip sample grades up to 64% Fe have been returned, evaluating their significance in terms of target size and grade is not possible due to scarcity of outcrop. A reconnaissance drill program is scheduled for the 2nd quarter 2006.
