Australian multi-commodity exploration and development company FairStar Resources Limited(ASX: FAS) (FairStar) is pleased to announce details of the Company’s Maiden MineralResource Estimate of 17.67 Mt @ 58.4% iron (Fe) at its Steeple Hill Iron Project (S H I P) inWestern Australia’s eastern goldfields.

The Mineral Resource is in the Indicated Resourcecategory but the Company believes that thealluvials have good continuity along 10 Kms ofthe valley, but with local variability due todeposition in a meandering creek environment.The alluvials were derived from erosion of anearby hematite BIF outcrop into a creek valley.The average width of the mineralized alluvialsis 1,040 m across the valley.

The Mineral Resource was confirmed from drillingprograms at the S H I P, which drilled a total of4,204 m across 450 holes, and also a program of145 trenches. A total of 1555 aircore samples,including 71 duplicate samples, were submittedfor processing by Nagrom MetallurgicalLaboratory. The samples were washed andscreened, and the +0.6mm fraction passedthrough a dense media separator at SG 3.4 toproduce a hematite concentrate. This concentratewas then analysed by XRF for the standard ironore suite of elements plus LOI.

Details of the Indicated Resource estimate are shown in the attachment following thisannouncement.

The delivery of the Maiden Mineral Resource at S H I P represents a major milestone for theCompany in its plans to fast track the development of the project into a significant export-gradehematite iron mining operation. Having successfully concluded the resource estimate,FairStar can now define a Probable Reserve within 2 months, once other studies arecomplete.

FairStar’s initial focus is on developing a shallow alluvial iron mining operation at the S H I P(as Stage 1 of the project’s development). This will allow for an accelerated developmenttimeframe for the project due to the low extraction cost, increased speed of mining and ease oftreatment (in comparison to hard rock mining). The mineralisation occurs from surface withnegligible overburden and the alluvials are free digging saving on blast-hole drilling andexplosives.

The Company then plans to embark on further development at the project via a hard-rock ironmining operation, in what would be Stage 2 of the project.

The S H I P currently has a strike length of 10 km, and remains open in the south of the projectarea. This area will be the focus of the next phase of drilling, where the Company plans toundertake a program of up to 100 holes, to further expand the Resource base.

Commenting on the maiden Resource Estimate in accordance with the JORC Code FairStarResources managing director Kevin Robertson said: “The confirmation of our MaidenResource Estimate in accordance with the JORC Code at Steeple Hill is a major milestonein the development of the project. To achieve this result in such a short timeframe is atestament to the Company’s commitment to the development of the project. We lookforward to continuing the rapid development of the project into a significant iron oremining operation.”

The S H I P Indicated Resource estimate was completed by AMC Consultants Pty Ltd anddetails are provided in Appendix 1, attached to this announcement.

The Steeple Hill Iron Project is 100% owned by FairStar Resources and is located in WA’seastern goldfields, 110 km east of Kalgoorlie. The project is in close proximity to major railinfrastructure, with the Trans Australian Railway passing 23 km south of the project area.

As previously advised, the Company is making strong progress in its development plans for theS H I P.

Infrastructure developments are in progress, and rail and sea-bound transport corridors havebeen established. In addition, site infrastructure and other required licenses are currently beingaddressed. Ethno-graphic and noise surveys have been completed at the project, and fieldworkfor the environmental surveys has been completed (and is due for final reporting in October).Native title negotiations are well advanced and a positive outcome is expected in the near term.

FairStar has also commenced discussions with a number of Chinese groups and otherinterested parties from Asia on project funding for the S H I P, as well as potential off takearrangements and equity investment in the Company. It will advise the market further on thesematters in due course.

Data Collection

Air core drilling of 450 holes has tested the alluvial gravel over an area of about 11 km long and 1.4 km wide. Hematitic gravel and gravel-bearing alluvial clays have been intersected in drillholes from surface to 9m below surface with an average thickness of 3m. A surface layer of soil, transported overburden and disturbed gravel reaches a depth of up to one metre.

Drilling has been completed at a nominal 200m x 200m spacing with some lines infilled to 100m spacing. Drillhole collars were surveyed by differential global positioning system. No downhole surveys were completed but significant deviation is unlikely in the shallow vertical drillholes.

Geological and sample information from 146 trenches were used for validation of the interpretation but the trench data were not used directly in the estimation of recovery or grades. Nine drillholes were twinned by closely-spaced holes to examine short range variability.

All drillholes were vertical and most sampling is at one metre intervals. The entire sample was bagged at the drill site for processing at a commercial laboratory. The sample processing protocol is outlined below.

• Weigh the sample.

• Screen the sample at 6 mm.

• Crush the oversize fraction to less than 3 mm, and add back into the <6 mm fraction.

• Wet screen at 0.6 mm, and save both the <0.6 mm and >0.6 mm fractions.

• Attrition the >0.6 mm fraction to remove adhering clay and surface alumina.

• Dry and weigh the clean >0.6 mm fraction.

• Pass the >6 mm fraction through dense media separation (DMS) at density of 3.4 t/m3.

• Dry and weigh the underflow fraction.

• Split out a sub-sample for X-ray fluorescence (XRF) analysis.

• Report dry underflow mass as percentage of the total sample.

XRF analyses were completed for iron, silica, alumina, phosphorus and other trace elements and oxides.

A total of 48 density determinations were completed by inserting a tube of known volume into in situ alluvial material exposed in trenches and weighing the sample. Densities were determined separately for each material type (Surface Layer, Gravel and Alluvial Clays). Duplicate determinations at an umpire laboratory that included sample drying indicated negligible contained moisture.

Quality control protocols were in place as outlined below:

• Repeat analyses at the primary laboratory.

• Repeat analyses at an umpire laboratory.

• Duplicate sample preparation and analysis at an umpire laboratory.

• Duplicate density determinations at an umpire laboratory.

Quality control results show acceptable precision in recovery determination, analyses and density determination.

Fairstar provided AMC with digital topographic contours which AMC modified over the drilled area by incorporating the drillhole collars.

Mineral Resource Estimation

The Steeple Hill Mineral Resource estimate is based on the interpretation of the contacts between hematitic gravel, gravel-bearing alluvial clays and weathered bedrock. The top one metre in all drillholes has been interpreted as the Surface Layer. Digital terrain models (DTMs) of the geological contacts were developed from the downhole intersections. The DTMs were extended 100m beyond the limit of drilling.

The Mineral Resource estimate was completed using Datamine mining industry software. A volume model was developed with a 100m east x 100m north parent cell split to 25m x 25m to delineate the near-horizontal geological boundaries and topography. The volume model formed a single cell across the thickness of each geological domain.

Assays were composited across the geological domains such that each drillhole had a single composite for each geological domain that it intersected.

Estimation of concentrate recovery and concentrate iron, silica, alumina, phosphorus and manganese oxide grades were completed using ordinary kriging with parameters derived from a study of variography. The average of the density determinations within each geological domain were assigned to the model.

The model was validated by statistical and visual comparison of data and estimated grades and by alternate estimates.

AMC considers that the data spacing, data quality and geological interpretation are appropriate for classification of the estimate as Indicated Mineral Resource. AMC considers that this classification is appropriate when the estimate is considered in its totality. On a local scale the thickness of Gravel and gravel-bearing Alluvial Clay and the recovery of gravel from those sediments could be highly variable.
