1. Location & Tenure EPC650 is located in the Taroom Shire, about 35 km west of Wandoan and 55km south of Taroom, on the Western Downs of Queensland. These townships are accessed via Leichhardt Highway. Topographically, EPC650 consists of low, rolling hills, some with rubbly Jurassic sandstone outcrops, creek flats, and deeply incised creeks. Horse Creek is the largest drainage, effectively bisecting the EPC, draining from SSW to the NNE. Access to the EPC is via tarred and graded, dirt shire roads. The EPC is bisected by the graded, dirt-surfaced Bundi-Ryalls Rd. Taroom Coal lodged MDL application MDL373 over the entire EPC650 area in February 2007. This application is still with the Queensland Department of Mines and Energy. 2. Geology EPC650 is in the Surat Basin and the target sequence is the Juandah Coal Measures, part of the Injune Creek Group. The Juandah coal measures in EPC650 are comprised of 5 main seam groups. The main seam groups are named UG, Y, A, B, BC and C. The alphabetical name series is based primarily on old Brigalow Mines (former tenure holders) nomenclature. The seams are separated by interbedded to massive sandstones, siltstones and mudstones. The non-coal units are only moderately well lithified and tend to be reasonably soft. The coal typically has a vitreous lustre. The coal occurrence in EPC650 is being assessed as an open cut mining development. 3. Current Exploration Since the previous announcement in February 2008, Taroom Coal has completed drilling, sampling and analysis of 118 new holes. Table 1 shows a summary of this drilling. This drilling campaign commenced in March 2008 and was completed July 2008. Two contract drill Rigs were deployed during the programme. Fifty two of the holes were 4” 4C core, drilled for coal quality analysis. The balance of 66 holes were 125mm open holes. Total drilling for core was 2,950m with 3,960m of open hole. This drilling was designed to expand existing measured and indicated resources, ultimately to support a reserve statement over a potential mine area defined in prefeasibility mining studies early in 2008.

were drilled to achieve 250 x 250m grid pattern, utilising pre existing holes to supplement the pattern if possible. Down hole geophysical logging has been completed on 100% of the open holes, 2 core holes were unable to be logged due to unfavourable ground conditions. On the cores, ply by ply and stone intervals were tested for raw quality including proximate analysis, total sulphur, specific energy, relative density. Seam composites were formed and float sunk at CF1.55 with product analysis on the CF fraction including proximate analysis, ultimate analysis, specific energy, total sulphur, ash chemistry, ash fusion and hard grove index. A cluster of 4 of the cored holes (C8046-49) were drilled centrally in the tenure and subjected to detailed pre treatment and sizing analysis to add to coal washability study data.

4. Data & Modelling The new drilling was added to the previous dataset for the Elimatta model. Minescape 4.116 Stratmodel stratigraphic modelling system been used to construct the model. This model has been used to generate volumes for the resource estimate. Coal quality has been composited against seam intervals into Minescape Tables and queried during volume calculation. 4.1 Quality The new coal quality data has been added to the dataset and remodelled. Quality is composited and reported at a common moisture basis of 8% (the average air dried moisture of the samples) with a Preston and Sanders density correction being applied from the as reported data. Three quality sub models are contained within the Elimatta model – Raw, Wash and Product. The raw model values include Ash, CV, FC, SE, moisture, VM, hardgrove and CSN. The Wash sub model includes bore core yield and ash for F1.35 to F1.55 and F2.7 density washes. The product sub model is based on data derived from testing CF1.55 product and contains Ash, VM, FC, TS, SE, hardgrove, ash fusion, ash chemistry and ultimate analysis. Wash plant pre feasibility design, with input from pre-treated and extensively washability tested 4” core (2007 drilling) has been used to generate a wash plant simulation of the Elimatta deposit. A relationship between raw ash and predicted wash plant yield has been derived on a suite of LIMN simulations at 1.60 DMC cut point producing an export thermal coal. This simulated yield is modelled in addition to the bore core mass yield and product ash. In situ density has been estimated using the Secondary Model 1 from Meyers et al, 2004 (ACARP project C10042). In-situ moisture has also been estimated using the in situ moisture model from the same study (ACARP project C10042, Meyers et al, 2004). 5. Extrapolation, Points of Observation Density & Resource Categorisation Measured resources have been estimated using cored coal quality data (minimum prox, density and moisture analysis) with a maximum point of observation spacing of 250m with extrapolation radius of 250m on the quality point plus intervening structural points of observation at 125m radius. A structural point of observation is a borehole fully corrected to its downhole geophysical log. This density of data gives

the confidence to report measured resources where the seams split and wedge as is well known in the Surat type coal measures. Indicated resources have been estimated using cored coal quality data (minimum prox, density and moisture analysis) with a maximum point of observation spacing of 500m with extrapolation radius of 500m on the quality point plus intervening structural points of observation at 250m radius Inferred resources have been estimated using cored coal quality data (minimum prox, density and moisture analysis) with a maximum point of observation spacing of 1000m with extrapolation radius of 1000m. These data requirements are conservative but deemed prudent given the nature of the Juandah Coal Measures reported. 6. Restrictions applied to resources Only coal units within seams have been reported as resources. Non-coal units within seams are not included in the resource quantities. Plies less than 100mm thick have not been included in the resource estimate. The EPC boundary is applied as the absolute limit to resource calculations. The upper seams individual seam sub crop and splitting limits restrict their resource areas. Because the UG and Y are close to the surface, the undulatory topography causes many weathering ‘windows’ in these seams and they have complex limit geometry. The C seam resource is limited to an area defined by the 10:1 incremental overburden ratio (bcm waste: coal tonnes) to the C from the B seam floor. Only the C Seam has a ratio limit to resources. Both the variable separation from the B and dispersive character of the C mean a large portion of the C occurrence sits at very high incremental ratio. Application of the 10:1 limit restrains the resource to the area deemed at present to have the greatest mining potential. There is future potential to expand this resource area as C seam data is increased and the relationship to the B is better defined.

7. Resources Based on the current work, 129Mt of Measured Resources, 75Mt of Indicated Resources plus 40Mt of Inferred Resources are estimated to occur in EPC650. The following Tables show the break down of these resources. Table 1. Coal Resources within EPC650 September 2008 Horizon Total

Table 2 shows the total resources by overburden ratio to the B seam. The C seam resource area is additionally limited by a 10:1 incremental ratio cut-off from the base of the B. Table 2. Coal resources within EPC650 by vertical overburden ratio February 2008

Totals within resource categories have been rounded down reflecting the confidence of the respective resource type. Density is estimated in situ based on bore core quality data inputted to the Secondary Model 1 from Meyers et al, 2004 (ACARP project C10042). The BC seam has density of coal quality and geophysically logged points of observation to support indicated and inferred resources. Due to the thin total coal in the 3 BC plies (BC1, BC2 and BC3) resource total for the BC do not exceed the rounding threshold therefore it reports no tonnage. See Section 8 below for BC tonnages.

Category based rounding cuts around 5Mt out of the UG seam resources. This quantity added to the reported tonnage above gives a total quantity only 1Mt different from the February 2008 total. Table 3 shows average coal quality values, by seam, for the measured resources in seams UG-B and for the C seam inferred resource. Raw ash ranges from 18 to 30% adb with high volatile matter (33-39%) refecting the rank of the Jurassic coal present. Taroom Coal previously announced a Vitrinite reflectance R

0max of 0.42 for the Elimatta

deposit. Raw total sulphur is low with a maximum of 0.33% adb. This level remains low even when considered on a sulphur per unit of energy basis. Again, related to rank and coal type, in situ moisture of the coal is estimated at high levels of 13-15%; this level is expected from Surat/Moreton coal of this rank. Resources have been made with densities of in situ coal based on the methodology of Meyers et al, 2004 (ACARP project C10042). Float sink on Taroom’s 4” Elimatta bore core dating back to 2004 show 60-80% mass yield with a low ash product in the 9-11% range. The simulation yield based on the LIMN simulation of the 1.60 cut point DMC plant returns predicted plant yields (including a factor for organic efficiency) of 55-70% assuming a 16% moisture product. The simulation provides a product with 9.6% ash, 26.5 mj/kg (ad) energy (est 24.4 mj/kg gar at 16% mar). The Elimatta coal has a Hardgrove Index of 31-33. Ash fusion temperatures are good with spherical temperatures all >1350ºC. Empirical slagging indices (e.g. 0.8*IT+0.2*HT >1340) show low potential for slagging. Fouling is not anticipated with good ash chemistry base/acid ratios and low Na

20 in ash.
