. . . Quarterly Activities Report for the period ending 31 March 2009
Highlights from …iron’s new horizon
-
Scout drill testing was completed in the Hutch joint venture area with 1,104 metres of air core drilling in 45 holes. Iron-bearing gravels were intersected at all areas drill tested.
-
In February, Eastern Iron released a summary of all results from the scout drilling program (ASX announcement, 16 February 2009). Drilling results have identified twelve large channel iron deposit exploration targets in NSW with iron grades comparable to pre-concentrate grades at some major West and South Australian magnetite deposits. Most Eastern Iron drill intersections are from the surface, in shallow, free-digging gravels that can be mined without the need for significant waste stripping and blasting.
-
Magnetic separation upgrade test work and iron ore assay results have been received for a number of prospects. Highlights include:
Belah Tank Prospect - 52.4% Fe from EIAC178 (2-3 metres down hole)
Gromit Prospect - 53.8% Fe from EIAC396 (5-6 metres down hole)
Wendoline Prospect - 49.2% Fe from EIAC329 (5-6 metres down hole)
-
Analysis of results of XRF bulk oxides indicates that there is regional variability of iron and contaminant contents of magnetic pisolite between prospect areas. This may result in tailored beneficiation pathways for ores from different prospects.
-
Assay results of magnetic separation tests for the trial resource definition drilling at Belah Tank are in line with previously reported results which indicated that a single pass magnetic separation could produce grades of ~50% Fe.

EXPLORATION
Cobar Project - Hutch Joint Venture Drilling
The Hutch joint venture area is approximately 30 kilometres north of Cobar via a sealed road with parts of the palaeochannel system some 18 kilometres from the nearest operating rail line. The joint venture with Drysdale Resources (Drysdale) (a private unlisted company) covers alluvial material, particularly iron, in EL 6751. Drysdale retains the rights to base and precious metals in basement rocks.
Scout drill testing of an extensive iron-bearing palaeochannel network (Figures 1 and 2) was completed in the joint venture area, where access issues had previously delayed work. Air core drilling of 1,104 metres was completed in 45 holes (EIAC0498-0542) and iron pisolite-bearing gravels were intersected in all areas tested. Samples have been submitted for bulk (preconcentrate) iron content and selected samples will be subjected to magnetic separation test work and bulk iron quality analysis.

MAGNETIC SEPARATION TEST WORK
Samples collected during the major scout drilling phase (reported in ASX announcement, 16 February 2009) have been subjected to magnetic separation testing and subsequent analysis of bulk oxide and minor elements by XRF methods. Drill samples have been collected in bags containing cuttings for individual metres of each drillhole. These samples are screened and then passed over a barrel magnetic separator (Figure 3). This relatively simple processing step aims to replicate a low cost, bulk mining operation and results in a rapid upgrade of iron content and reduction in contaminant mineralogy, without the need for crushing or grinding.

Figure 3. Barrel magnetic separator, processing drill samples at MetCon Laboratories. Note the magnetic product adheres to the barrel and is deposited in a separate sample bin to the discarded, low iron, non-magnetic component.
To date, 1,509 samples have been processed from nine prospect areas. Table 1 shows the best XRF results of magnetic products at each prospect as well as an average of all samples taken at that prospect. On an individual metre basis, magnetic product recovery generally varies between 5% and 30% with apparently little correlation between head grade of gravel and quality of magnetic iron product. One result of the work to date has been the identification of possible regional trends in iron and contaminant mineralogy. For instance, samples from the Wendoline prospect have a relatively low alumina content which does not vary between samples. However, iron and silica levels at the Wendoline prospect vary between pisolite samples and also along the length of the palaeochannels. Generally, magnetic product has a simple mineralogy of iron, silica and alumina with very minor amounts of other contaminants, such as phosphorous or sulphur. The recognition of varying mineralogy between prospect areas may assist in developing a “tailored” approach to beneficiation for individual prospect areas.

Table 1. Summary of magnetic separation test work results completed at each prospect to date with a selection of results from better individual metre samples and a summary of the average at each prospect from scout drilling. Samples have been passed over a fixed magnet, barrel separator and the relative abundance of rejected material and magnetic product measured. Magnetic products were then subjected to XRF analysis.
- Note: Analyses conducted by ALS using X-Ray Fluorescence Spectrometry with Loss on Ignition (LOI) determined using ThermoGravimetric Analyses at 1,000°C.
Further fine grinding, floatation and pyro-metallurgical test work programs are being considered and joint funding of these activities will be pursued with potential customers. Opportunities for joint marketing arrangements with other iron ore explorers and developers are being sought and considered. The test work program in progress will provide information on the consistency of product grade and its likely sale price for input into economic studies.
Staffing
Eastern Iron is pleased to announce the appointment of Owen Janes to a consultancy role guiding resource assessment and iron channel modeling. Owen is an experienced iron ore specialist with postgraduate qualifications in geostatistics and has worked in exploration, development drilling and resource modeling at major Pilbara iron ore operations. His experience in iron ore resource modeling in Western Australia, particularly on channel iron deposits will enhance the ability of Eastern Iron to rapidly progress existing palaeochannel projects, including the Belah Tank resource drilling trial as well as assisting with the assessment of further iron exploration and development opportunities currently being considered by the Company.
