NOWA NOWA IRON PROJECT
Eastern Iron continues to focus its activities on the evaluation of a possible mining development at the Nowa Nowa Project in eastern Victoria. During the quarter the Company finalised the acquisition of a 100% interest in the project, announced a Maiden JORC Resource for the Five and Seven Mile iron deposits and released the results of preliminary metallurgical analysis. The Company will focus on progressing the project to a Scoping Study during the next quarter.

During the quarter the Company announced that it had exercised its option to acquire 100% of the Nowa Nowa Iron project in eastern Victoria from holder Waygara Mines Pty Ltd (“Waygara”). The successful transfer of the enclosing exploration license 4509 to Eastern Iron was completed following approval of the transfer by the Victorian Department of Primary Industries issued on the 3 February 2012.
Under the terms of the option agreement Eastern Iron paid $100,000 and allotted 1 million shares to Waygara on transfer of the title. A 1% revenue royalty is payable from production.
Resource Estimate
Early in February 2012 Eastern Iron released details of an initial resource estimate for the Five and Seven Mile deposits at Nowa Nowa.

March 2012 Quarterly Report

The resource estimate was compiled by H & S Consultants Pty Ltd (“H&S”) using data from drilling carried out in the 1950’s by the Victorian Government. Estimates were based on 593 assays from 24 drillholes (1,309m). All but four of the drillholes are vertical and are on a nominal 30m X 30m grid with an average depth of 99m.
The Resource has been classified as Inferred because it is based on drilling and assay data that is not verifiable due to its age. The lack of density measurements also introduces a level of uncertainty. The Inferred Resource estimates at a cut off of 40%. Total Fe are shown in the table below.
Inferred Resource Estimates at a cut off of 40 % Fe
| Zone | TONNES (MT) | SG | Total Fe % |
| Five Mile | 8.92 | 3.90 | 49.2 |
| Seven Mile | 0.55 | 3.90 | 48.3 |
| Total | 9.47 | 3.90 | 49.1 |
Note: Significant figures quoted do not imply precision and are to minimise round-off errors.
The Seven Mile deposit outcrops at surface and has been the subject of small scale mining in the past. The mineralisation, although originally magnetite, is now almost completely oxidised to hematite and may represent an opportunity to mine a coarse DSO lump hematite product early in the life of the operation. Further drilling will be required to outline the mineralised area.

The mineralised body at Five Mile occurs below a variable thickness of younger sands and volcanic rocks and as such is largely unweathered. Primary mineralisation consists predominantly of magnetite with hematite becoming more common at depth. The mineralisation is also quite massive and as the section below indicates, at the 40% Fe cutoff there is little internal waste. This should assist mining efficiency and once the overburden is removed waste to ore ratios during mining should be low.

Five Mile Deposit: Section looking north showing Fe grade blocks and drillholes
Additional resource potential exists in the surrounding area and in a broad magnetic feature between the Five and Seven Mile deposits known as the Six Mile prospect. This may represent further faulted bodies of magnetite/hematite mineralisation under younger volcanic rocks and will be drill tested at a later stage during resource definition.
Metallurgical Results
Drill core samples collected by Eastern Iron from a diamond core hole drilled by a previous explorer at the Five Mile deposit have been submitted for preliminary metallurgical analysis consisting of assay of head samples, crushing and grinding at various sizings, dry low intensity magnetic separation (LIMS), Davis Tube Recovery (DTR) and quantitative electron microscopy (QEMSCAN). The work was carried out by ALS AMMTEC and supervised by Resource Engineering Pty Ltd. The object of this limited program has been to determine product characteristics for a potential mining development at Nowa Nowa.
Fresh unoxidised composite half core samples were taken from drillhole NND08002 which intersected a continuously mineralised interval from 45.8m to 113.5m (62.9m) and averaged 51%Fe. Samples taken from this core were as follows:
| Sample ID | Drillhole Number | From (m) | To (m) | Interval (m) |
| Upper Composite | NND08002 | 61 | 65 | 4 |
| Middle Composite | 91 | 93 | 2 | |
| Lower Composite | 104 | 107 | 3 | |

Head assay results from the three composite samples were as follows:
| Fe | SiO2 | Al2O3 | P | S | |
| (%) | (%) | (%) | (%) | (%) | |
| Upper Composite | 62.3 | 6.75 | 0.9 | 0.010 | 0.540 |
| Intermediate Composite | 55.4 | 10.6 | 2.28 | 0.013 | 0.800 |
| Lower Composite | 60.0 | 8.24 | 1.11 | 0.008 | 2.560 |
The results show that a substantial proportion of the mineralisation has a high Fe content and could be classified as direct shipping (DSO).
The three samples were crushed to -6.3mm and separated by dry LIMS separation into a magnetic and non-magnetic product. Assay results and mass recoveries for the magnetic products from each sample are summarised in the table below:
Analysis of -6.3mm Dry LIMS product
| LIMS | Wt. | Fe | SiO2 | Al2O3 | P | S | |
| -6.3mm | (%) | (%) | (%) | (%) | (%) | (%) | |
| Upper Comp | LIMS Mags | 99.7 | 61.90 | 6.70 | 0.92 | 0.009 | 0.620 |
| Middle Comp | LIMS Mags | 35.5 | 58.90 | 9.31 | 1.34 | 0.007 | 0.410 |
| Lower Comp | LIMS Mags | 69.10 | 64.00 | 6.30 | 0.77 | 0.007 | 0.610 |
Although dry LIMS separation would be more applicable to lower grade material in the deposit the results do suggest that the ore is highly amenable to this low cost beneficiation process producing a +61%Fe product at an average weight recovery of 68%.
Samples from the three composite samples were also tested by Davis Tube (DTR) analysis at grind sizes of 80% passing 250, 106, 75, 53, and 38 micron. The results from the coarser grinds are summarised below and indicate that a high grade product can be produced at these coarse grindsizes:
Analysis of DTR magnetite concentrates at 250 micron grind
| DTR Conc. | Wt. | Fe | SiO2 | Al2O3 | P | S | |
| (%) | (%) | (%) | (%) | (%) | (%) | ||
| Upper Composite | 250 micron | 86.1 | 67.50 | 3.63 | 0.40 | 0.006 | 0.150 |
| Intermediate Composite | 250 micron | 15.5 | 67.60 | 3.30 | 0.35 | 0.003 | 0.092 |
| Lower Composite | 250 micron | 44.2 | 68.70 | 2.82 | 0.30 | 0.003 | 0.084 |

Product Transport
As part of its investigations into the potential for mine development at Nowa Nowa, Eastern Iron commissioned a study into product transport options by logistics consultants Innovative Shipping Pty Ltd. Innovative Shipping identified several possible transport options, these include:
- Trucking iron product from Nowa Nowa to one of two wharves at Eden on the NSW south coast.
One of the wharves is operated by South East Fibre Exports Pty Ltd (SEFE) who operate a private terminal with its own jetty, shiploader and conveyor system on the southern side of Twofold Bay. The berth can accommodate vessels up to Small Panamax Class of about 65,000 DWT comfortably and is designed for loading high volume woodchips. Eastern Iron has commenced preliminary discussions with SEFE with a view to entering into a cooperative agreement to investigate the potential for loading iron product from Nowa Nowa from this facility.
Close by the SEFE operation is a multi user wharf built by the Australian Navy to handle munitions. The berth has capacity for vessels up to 36-38,000 DWT and apart from Naval use is used for other cargo including forest logs.
-
Trucking from the mine site to a possible barge trans-shipping facility in the Port Anthony/Corner inlet area of southern Victoria. A barging facility is currently under construction at Port Anthony and will be assessed for suitability closer to a development decision at Nowa Nowa.
-
There are several port options at Westernport/Port of Hastings which have deep water anchorages and are serviced by an operating railway line. Further discussions will need to be conducted with the operators of these facilities before any decision is made as to their viability for export of iron product from Nowa Nowa.
EULOGIE IRON - VANADIUM PROJECT
Concept Study
Eastern Iron has completed a concept study into a potential development of the defined resource at the Eulogie project. The financial model for the study has yet to be finalised but has indicated capital costs of between $500-600 million producing 3.2 million tonne of magnetite concentrate to be exported via Gladstone Port.
Eastern is currently in discussions with the Gladstone Port Corporation with a view to securing an MOU covering the potential to ship concentrate from the port area.
Eastern Iron has approached several parties with a view to securing funding for the feasibility study into development at Eulogie. These discussions are ongoing.
HAWKWOOD IRON PROJECT
Resource Estimate
Eastern Iron has completed a resource drilling program at Hawkwood The program consisted of 2,689m in 17 reverse circulation (RC) drill holes and was designed to test magnetite-bearing ferrigabbro layers inferred to be present at shallow depth from an interpretation of the results of an earlier airborne magnetic survey.

March 2012 Quarterly Report
==> picture [119 x 68] intentionally omitted <==
Previous drilling by Eastern Iron at Hawkwood has confirmed that elongate airborne magnetic anomalies represent layers of magnetite enriched ferri-gabbro within a layered basic igneous complex. Collectively these anomalies extend over 12kms along strike and consist of ferrigabbro layers up to 100m thick. Holes have been drilled on strike normal lines approximately 400m apart. Holes are spaced at 50m across strike.
Chip samples from the drilling were assayed for iron and associated elements and samples were composited over 6m for Davis Tube (DTR) analysis. Concentrates from the DTR analysis were assayed for Fe, SiO2, Al2O3, P, LOI, CaO, K2O, MgO, Mn, Na, S and TiO2..
Results are currently being compiled and the resource estimate will be released shortly.
