CENTRAL QUEENSLAND IRON PROJECT
Eastern Iron is investigating the potential for the development of magnetite iron ore deposits at several locations in proximity to existing rail and port infrastructure on the central coast of Queensland. Principal among these are the Eulogie and Hawkwood projects.

Resource Drilling
Eastern Iron has commenced a resource drilling program at its wholly owned Eulogie project. The drilling consists of 3,500m in 31 reverse circulation (RC) drill holes. To date 23 holes have been completed. The drilling is designed to test the mapped outcrop of magnetite-bearing ferrigabbro and provide an estimate of grade and tonnage in this portion of the resource.
The total exploration target resource has previously been estimated at approximately 500 – 1,000 million tonnes[1] of magnetite-bearing ferrigabbro to between 100 and 200m below surface. Whilst only a portion of the exploration target resource will be tested in this drilling program, sufficient information for concept development studies should be provided.
A resource estimate based on this drilling should be completed during the September quarter.
1 Potential exploration target tonnages and grades in this report are conceptual in nature as there has been insufficient exploration to define a Mineral Resource and because it is uncertain if further exploration will result in the determination of a Mineral Resource. Tonnages and grades are not to be quoted outside this context.

Metallurgical Study
Mineral Engineering Technical Services (METS) has completed a preliminary metallurgical testwork program on drill core samples from previous drilling carried out at Eulogie. Drill core samples were composited into two samples representing oxidised and fresh ferrigabbro. Head assays for the two samples were 13.7% Fe and 15.1% Fe respectively.
Davis Tube Recovery (DTR) testwork was undertaken on the fresh sample for grind sizes at P100% passing 150 micron, 75 micron and 45 micron. Results were as follows:
| Grind Size | Wt % | Fe % | SiO2 % | Al2O3 % | TiO2 % | P % | V % | S % |
|---|---|---|---|---|---|---|---|---|
| 150 micron | 17.6 | 59.34 | 2.72 | 3.61 | 7.03 | 0.002 | 0.541 | 0.65 |
| 75 micron | 16.8 | 61.15 | 1.42 | 3.02 | 6.55 | 0.002 | 0.561 | 0.57 |
| 45 Micron | 15.1 | 61.94 | 1.52 | 2.87 | 6.34 | 0.002 | 0.57 | 0.66 |
The titanium content, at 6-7% at Eulogie, is higher than at Hawkwood which reduces the iron content of the concentrate and is less favourable as an iron ore feedstock. On the positive side, around 70% of the iron is recovered to concentrate at a grind size of 150 micron. Coarser grind sizes will be examined to determine if magnetic separation could reduce the quantity of material required for finer grinding to a final product.
High intensity magnetic separation (WHIMS) and QEMSCAN testwork concluded that it is unlikely that an ilmenite by-product can be produced from the non-magnetic tail.

The results of the study are currently being assessed to determine the scope for further metallurgical testwork.
Product Transport Study
Innovative Shipping Pty Ltd has completed a preliminary study into options for transporting iron product from the project site to Gladstone Port.
The study concluded a range of options exist for product transport, including via either the Blackwater or Moura rail systems or a combination of rail and/or trucking options via existing road and rail infrastructure.
There are several options for bulk loading at Gladstone Port, some of which are tonnage and timing constrained, with the choice of a viable option dependent on the timing for development.
Hawkwood (EFE earning 80%)
A three hole, 637m diamond drilling program was completed at Hawkwood in March 2011. The drillholes provided information on the dip and thickness of the magnetite-bearing zones (ferrigabbro).

Half core was sent for analysis including Davis tube determinations, the results are summarised below.
| below. | ||||||
|---|---|---|---|---|---|---|
| Hole No | From (m) | To (m) | Interval (m) | Fe% (Head) | DTR% | DTC% |
| HWD001 | 174 | 221 | 47 | 15.6 | 15.2 | 66.6% Fe |
| HWD002 | 126 | 190 | 64 | 15 | 15 | 64.3% Fe |
| HWD003 | 88 | 128 | 40 | 13.5 | 14 | 67.0% Fe |
The ferrigabbro units dip approximately 50 degrees north and the units represented in the table above outcrop at surface. The DTR results are a measure of the percentage of the ore recovered to concentrate, the DTC results are the iron content of the concentrate.
The average concentrate grade is shown in the table below. Of note are the low SiO2, Al2O3, and TiO2 concentrations.
| Fe% | **V2O5% ** | TiO2 | SiO2 | **Al2O3% ** | P% | S% |
|---|---|---|---|---|---|---|
| 66.6 | 0.67 | 2.2 | 1.8 | 1.7 | <.001 | 0.14 |
Further resource drilling is planned for Hawkwood and is scheduled to commence in mid August.
North Burnett Rail Transport Options Study
Eastern Iron has contributed to a cooperative study into rail transport options for mineral transport in the North Burnett region of Queensland. The study has been jointly funded by Eastern Iron, the Queensland Government and other potential users, Macarthur Coal and Australian Bauxite Limited.
The study examined the potential options for upgrading the rail link to Gladstone port via the currently unused Maryborough rail line. A variety of options were examined for total hauled tonnage, line capacity and rail locomotives and wagons which flowed through to capital cost estimates for the upgrade and operating cost estimates for the individual users. In the case of producing around 5Mtpa product from Eastern Iron’s Hawkwood project it was estimated that the cost would be around $20-25/t delivered to Gladstone, including all rail user and operating costs and including a return on capital for the rail upgrade, wagons and locomotives and a spur line and loading facility at Hawkwood. This is a very preliminary estimate and further work will be required to define a more accurate cost.
FORWARD PROGRAM
It is planned to complete the current resource drilling program at Eulogie in the September quarter and finalise the resource estimate. Further metallurgical testwork may be undertaken depending on a more complete evaluation of the recently completed study. A concept study into a possible mining development at Eulogie will also be carried out together with initiation of baseline environmental work which ultimately would feed into an Environmental Impact Statement.
At Hawkwood the resource drilling program will be carried out.
