Eastern Iron Limited (ASX: EFE) is pleased to report on activities undertaken during the quarter ended 31 March 2014.
NOWA NOWA IRON PROJECT
www.easterniron.com.au
Twitter: @EasternIronEFE www.easterniron.com.au
The Nowa Nowa Iron Project is located some 250 kilometres east of Melbourne close to the Princes Highway, which provides access to several nearby towns and a proposed export facility south of Eden, approximately 200 kilometres further east (Figure 1 on next page).
Over the past 12 months, Eastern Iron has advanced a Definitive Feasibility Study (DFS) into the potential development of the magnetiterich Five Mile deposit. It is proposed that iron ore would be crushed and beneficiated to export quality at site, and trucked to a port facility at Two Fold Bay south of Eden in southern NSW.

Definitive Feasibility Study
Eastern Iron has previously released details of capital and operating costs arising from the feasibility study (ASX release 24 January 2014*) demonstrating that the Nowa Nowa Iron Project has an extremely low capital intensity (capital cost per tonne of annual production) of A$45/t. This compares favourably with virtually all proposed Australian hematite and magnetite projects, which generally range between $150-350/t.
Mining studies completed as part of the feasibility study have indicated that mineralisation within the area known as Five Mile North will be mined early in the life of the operation but is currently in an inferred resource category. Consistent with the requirements of JORC 2012, a short program of confirmatory drilling was required to upgrade the confidence level in the Inferred Resource areas before production and financial forecasts completed as part of the feasibility study can be released.
This drilling program was completed during March with an upgraded resource model due for completion in May. This information will feed directly into an updated mine plan and production schedule which will provide for finalisation of the DFS at the end of June.
*This information is extracted from the report entitled “Nowa Nowa Iron Project – Feasibility Study Results” announced to the ASX on 24 January 2014 and is available to view on www.easterniron.com.au. The Company confirms that it is not aware of any new information or data that materially affects the information included in the original market announcement and, in the case of estimates of Mineral Resources, that all material assumptions and technical parameters underpinning the estimates in the relevant market announcement continue to apply and have not materially changed. The Company confirms that the form and context in which the Competent Person’s findings are presented have not been materially modified from the original market announcement.

Metallurgical Testwork
During the quarter the Company completed further beneficiation testwork using large pilot-scale dry low intensity magnetic separation (Dry LIMS) equipment at Western Process Equipment (WPE) and supervised by ALS Global and Engenium in Perth, WA.
The results from this work represent a significant improvement on earlier test results which used smaller “laboratory scale” equipment and which had no capacity to vary drum speed.
Highlights from the latest large pilot-scale test results include:
-
Average iron recovery exceeding 90% suggests little of the low magnetic hematite is being lost to the non-magnetic fraction.
-
An average product grade of 58% Fe which is a significant improvement to the 56% Fe product grade realised from previous testwork.
-
Upgrade factors (i.e. from feed grade to product grade) have exceeded expectations and confirm that the Dry LIMs is highly effective in its application to the Nowa Nowa ore, even at a relatively coarse feed size of -6mm.
==> picture [596 x 41] intentionally omitted <==

==> picture [97 x 55] intentionally omitted <==
- The Dry LIMS has been highly successful at reducing sulphur from feed grades usually in excess of 2% to well below 1%.
The testwork was performed with larger composite drill core samples feeding onto a 914mm diameter, variable speed rotating drum magnet. The effects of varying the drum speed together with moisture content and sizing of the feed were measured. Selected intervals of drillholes were composited into five samples with grades distributed across the range of expected ROM feed.

Resource Drilling
Late in the quarter a program of RC drilling was completed at Five Mile North with the objective of upgrading the current inferred resource to a measured and indicated category for inclusion in the mining reserve of the Five Mile deposit.
==> picture [596 x 41] intentionally omitted <==
Page | 4
==> picture [97 x 55] intentionally omitted <==
A total of 10 RC holes totalling 590m were completed, locations are shown on the plan below.
==> picture [435 x 447] intentionally omitted <==
Figure 3: Drillhole locations Five Mile Deposit
All holes were vertical and generally drilled to shallow depths not exceeding 74m. Assay results from the drilling have now been received and are summarised in the table below. The results are consistent with results reported from earlier drilling completed by the Victorian Department of Mines in the 1950’s and used to compile the current resource. Significantly it was noted that the thickest intersections were in the easternmost holes NRC044, NRC045 and NRC047 with the resource still open in this direction.
Weighted average of all mineralised intercepts was 52.8% Fe confirming that the mineralisation in this area tends to be somewhat higher grade than the bulk of the resource.

Assay results have been provided to resource consultants and an updated resource estimate should be available in early May. Table 1, Sections 1 and 2 are included in this report to give the details of the new drillhole information. However, Table 1, Section 3 is not included at this time as there has been no material change to that information as previously reported.

Permitting
In January, Eastern Iron announced that the Victorian Planning Minister had advised the Company that it would be required to prepare an environmental effects statement (EES) to support its application for a work program approval for the Nowa Nowa Iron Project (ASX announcement 22 January 2014). This process is now well advanced and the scoping requirements for the EES were released for public comment on 9 April 2014. Once the scoping requirements have been finalised, the Company plans to proceed with related studies with the objective to lodge the completed EES with the Victorian Government before the end of 2014.
The project was also referred to the Federal Department of the Environment for assessment under the EPBC Act (1999). The Commonwealth has now advised that the proposed project is not considered a “controlled action” and therefore does not require further assessment and approval under the EPBC Act before it can proceed. This decision supports the view that this is a low impact proposal and effectively clears the way for the project to be assessed in accordance with State and Local Government requirements, thereby significantly reducing the expected time frame for granting the permit.

Grant of Mining Licence
In April the Company also announced (ASX announcement 23 April 2014) that Mining Licence (MIN 5571) covering the project area was granted by the Department of State Development, Business and Innovation. The MIN has been granted to Gippsland Iron Pty Ltd, a wholly owned subsidiary of Eastern Iron. The area covered by the mining licence is approximately 485Ha.
This is a significant milestone for the project and clears the way for a work program approval prior to development.
FUNDING
Late in the quarter the Directors announced that Eastern Iron had agreed to issue approximately 14.3 million new fully paid ordinary shares (“Shares”) at an issue price of $0.042 per Share to New York based Harland Capital Fund LLC (“Harland”). The first tranche of the share issue raised approximately $600,000. Harland was also granted a call option for a period of 60 days to subscribe for additional Shares at the same issue price of $0.042 to raise a further approximately $400,000. The term of the call option was subsequently amended by agreement to extend to 30 June 2014 and was accompanied by a further tranche of shares at the issue price raising a further approximately $100,000. The balance, raising approximately $300,000 is expected to be placed prior to 30 June 2014.
Once fully subscribed Harland will hold approximately 17% of the issued ordinary shares in Eastern Iron. After settlement of the first tranche of the placement Harland took up its right to nominate a Director to the Board of Eastern Iron and Mr Michael H. Giles, a representative of Harland, joined the Board.
On 29 April 2014 Eastern Iron announced that it proposes to undertake a Share Purchase Plan (“SPP”) which will provide existing eligible shareholders on the Company’s share register with the opportunity to subscribe for up to $15,000 worth of fully paid ordinary shares at the same price as the Placement ($0.042 cents per share), without incurring brokerage or other transaction costs.
Proceeds from the placement and SPP will be used to progress work on the Nowa Nowa Iron Project including completing the DFS and progressing studies related to the EES.

Table 1 report for Nowa Nowa Iron Project
Section 1 Sampling Techniques and Data
| Criteria | Commentary |
|---|---|
| Sampling | Reverse circulation (RC) percussion drillholes were sampled over 2 metre downhole |
| techniques | depth intervals via a sealed collar dust diverter and cyclone. |
| Diamond core was sampled nominally at 2 metre composite intervals at the | |
| boundaries of lithological contacts. | |
| Both RC and diamond core drill samples were 3-4kg in weight and pulverised in the | |
| ALS Adelaide laboratory to produce a fused disk for ME-XRF21 spectrometry | |
| analysis. | |
| Diamond core from the 1950’s Victorian Geological Survey (GSV) drillholes was | |
| nominally sampled by the GSV at both 5ft and 10ft intervals at the boundaries of | |
| lithological contacts and is reported in Bell, 1959 GSV Bulletin 57. EFE considers that | |
| there are no detrimental issues in the sampling procedure with regard to the resource | |
| estimation. | |
| Drilling | RC percussion drillholes were drilled using a 5 ½ inch (140mm) RC face-sampling |
| techniques | buttoned drill bit. |
| Diamond core drilling was drilled using triple-tube conventional wireline HQ (96mm) | |
| and PQ (122.5mm) diameter techniques. | |
| All EFE drillholes were drilled vertically and consequently diamond core was not | |
| orientated. | |
| All GSV drillholes were drilled vertically using conventional NQ (47.5mm) diameter | |
| diamond drillingmethods. Thereisnorecord ofthe core being oriented. | |
| Drill sample | The sample recovery for all the Eastern Iron Ltd (EFE) drillholes was excellent. RC |
| recovery | drillhole sample recovery was determined by visual inspection of 1metre bulk samples |
| in the field by an experienced supervising geologist. All assay samples submitted as | |
| two metre composites were weighed upon receipt at the laboratory. The consistency | |
| of these weights is monitored as part of Eastern Iron’s sample QAQC programme. | |
| Company protocol is that if any RC percussion drillhole returns less than 70% by | |
| volume of the drill cuttings over a 10metre interval, the drillhole will be re-drilled. | |
| Full core recovery was achieved in the EFE diamond drillholes except in minor | |
| instances where friable zones were intersected downhole resulting in core losses, | |
| typically occurring at the start of a new drill run. These losses were considered to be | |
| insignificant. | |
| Recovery rates of drill core from diamond drilling are closely monitored by the | |
| supervising geologist. Should the integrity of the drillhole or representivity of the | |
| sample become compromised, the drillhole is abandoned at the supervising | |
| geologist’s discretion. | |
| Recovery details for the GSV drillholes are not known. Historical geology logs do not | |
| document any significant core losses and EFE considers that there are no detrimental | |
| issues in this with regard to the resource estimation. | |
| Logging | All EFE drillholes have been geotechnically and geologically logged by an |
| experienced geologist for their entirety with a uniform set of company specific codes. | |
| Geological drillhole data is collected based on geological intervals as opposed to a | |
| metre interval basis. | |
| All data was digitally captured into purposed designed spreadsheet templates. All data | |
| is uploaded, validated and stored in the Eastern Iron company database. | |
| GSV drillholes were logged by Victorian government geologists. EFE has no | |
| knowledge of their qualifications or given levels of experience. As a result of twinning | |
| several of these drillholes, where there was excellent logging correlation, EFE has | |
| assumed that the data from these drillholes is valid for the resource estimation. |

|---|---|
| Sub-sampling | RC drillhole samples were split using a 75/25 riffle splitter mounted to the cyclone. A |
| techniques | 3-4kg composite sub-sample was produced, with the split samples sent to ALS |
| and sample | laboratories Brisbane and Perth for analysis. The bulk reject fraction of the sample |
| preparation | was bagged and retained on site for storage. |
| Diamond core was cut using a core saw for composite sampling. Half-core for HQ | |
| diameter drillholes and quarter-core PQ diameter drillholes were sampled | |
| respectively. The retained fraction of drill core has been securely stored and archived | |
| on site. | |
| Upon receipt at the lab, both EFE percussion rock chip and drill core samples were | |
| dried and crushed to a 70% passing at -6mm. The entire sample is then pulverised to | |
| an 85% passing at -75µm. | |
| Diamond core from the GSV drillholes was split using a core saw and half-core was | |
| composited for assay analysis. | |
| EFE have limited knowledge of the laboratory methods used for the GSV samples | |
| except as reported in Bell, 1959 GSV Bulletin 57 but it appears that samples were | |
| crushed, split and pulverised during their preparation. It is reasonable to assume that, | |
| as the samples were prepared by a certified independent laboratory, that industry-best | |
| analytical practices were employed at the time. As a result of twinning several of these | |
| holes, where there was excellent assay correlation, EFE has assumed that the data | |
| from these drillholes is valid. | |
| Quality of | EFE samples were assayed by ALS Global Laboratories Brisbane and Perth. |
| assay data | Assay samples were cast using a 12:22 flux to form a glass disk. The resultant disk is |
| and | in turn analysed for the industry standard iron oxide suite of elements by XRF |
| laboratory | spectrometry. LOI values were determined using a thermogravimetric analyser |
| tests | system. |
| EFE collected field duplicate samples at a ratio of 1 in 15 samples throughout all | |
| drillholes. RC duplicate samples are taken in the field using a riffle splitter mounted | |
| onto the drill rigs cyclone. Diamond core duplicate samples are prepared by the laboratory every 15thcrushed sample and inserted sequentially into the sample |
|
| sequence for each drillhole. | |
| Duplicate samples were analysed by ALS Global and triplicate QAQC samples by | |
| Bureau Veritas Mineral Laboratories Perth. | |
| Certified reference materials are inserted nominally every 15thsample using | |
| internationally accredited standards. | |
| Blanks are inserted at regular intervals within each batch of RC drilling samples and | |
| one per diamond drillhole to verify the cleanliness of laboratory sample preparation | |
| machinery. | |
| Good reproducibility was obtained in the comparison of results from the umpire quality | |
| control programme. A minor high bias for total SiO2and Al2O3(~0.15%) and | |
| corresponding low bias for Fe (~0.15%) was present in the assay standards. These | |
| biases are considered insignificant. | |
| EFE have no knowledge on the method of chemical method used by the GSV for | |
| assay analysis but it is reasonable to assume that best-practice industry standards | |
| were used. | |
| Verification of | Six of the historical GSV drillholes have been twinned by EFE drilling, comprising one |
| sampling and | RC and five diamond drillholes. Twinned drillholes were used to verify the geological |
| assaying | interpretation, confirm the assay tenor and to provide sample for metallurgical |
| testwork. All drillhole data and assays are consistent with those from the earlier | |
| independent GSV drilling. | |
| Data is captured in hardcopy format in the field before being transposed digitally into | |
| spreadsheets. Data entry self-audits are made routinely during this process. | |
| All data is validated prior to and upon uploading to the company database by purpose | |
| built in-house software applications. EFE’s database is compatible for use with | |
| MapInfo and Micromine software applications. | |

| Victorian Geological Survey data was obtained from historical reports and digitised | |
| manually, before being uploaded to the company database. | |
| Digital data for the project is stored on two separate remote computers as well as the | |

| Hard copies of drillhole & assay data, including report estimations, are kept secure in | |

| Location of | EFE drillholes collar co-ordinates and elevations were located in the field using a |

| of resource drilling, all drill collars were surveyed using a Trimble Differential GPS | |
| system with an accuracy of +/- 0.5m. DGPS drill collar data has been incorporated | |
| into the company database and is used for the resource estimation. | |
| All data is georeferenced and projected through the Map Grid of Australia (MGA) 1994 | |
| geodatum within Zone 55. | |
| All GSV drillhole collars were surveyed and documented on a local grid. Drilled in the | |
| 1950’s, the location of these drill collars were reprojected and georeferenced into | |
| MGA 1994 using MapInfo software. The comparability of data between historical and | |
| current twinned drillholes is excellent. | |
| EFE has produced a digital terrain model (DTM) and surface contour map from | |
| accurate levelling data that was recorded by geophysical contractors who carried out | |
| an airborne LIDAR over the prospect for Eastern Iron. The accuracy of this survey is | |
| within +/- 0.5m. | |
| All EFE drillholes were vertical and as drillholes are relatively short (<150m), it is | |
| assumed that any deviation would be negligible and have minimal impact on the | |
| resource estimation. No downhole surveys of drillholes were carried out... | |
| EFE is not aware of any downhole surveying on the vertical GSV drillholes and | |
| assumes any effect on the resource estimation is negligible. | |
| A table showing the location, dip, azimuth and depth of each drillhole is included at | |
| the end of this report. | |
| Data spacing | At the Five and Seven Mile prospects, nineteen and eight EFE drillholes were sited |
| and | on the main magnetic anomalies respectively. Staggered drill-centres were nominally |
| distribution | spaced at 25 metres across east-west cross-sections and 25 metres between drill |
| profiles. The drill layout was designed to provide the best possible integration and | |
| validation of the historical GSV drillholes. | |
| At the Five Mile prospect, six of the previously drilled GSV drillholes were twinned by | |
| EFE drilling to confirm their results. | |
| EFE considers the density of drilling is sufficient to establish the degree of geological | |
| and grade continuity appropriate for the Mineral Resource Estimation and | |
| Classifications applied. Continuity of the mineralisation is strongly supported by the | |
| ground-based geophysical survey data. | |
| EFE RC and diamond core samples were composited nominally into 2 metre intervals | |
| for head assayanalysis. | |
| Orientation of | The main body of mineralisation at Five Mile is almost horizontal. Drilling carried out |
| data in | by the GSV and subsequently by Eastern Iron was vertical to give close to true width |

| status | 2014 was approved in November 2011. EL 4509 was transferred from Waygara Mines Pty Ltd to Eastern Iron Ltd on February 2nd2012. |
| EL4509 is located within the Crown Land of the Colquhoun State Forest. No access | |
| agreements with landholder are required, however, notification and approval of | |
| proposed exploration activities is sought from the Department of State Development, | |
| Business and Innovation. | |
| EFE recognises the GurnaiKurnai people as the traditional custodians of the land | |
| situated on and immediately surrounding EL4509 and they are the Registered | |
| Aboriginal Party. A Project consent Deed was negotiated with the GunaiKurnai and | |
| has been assigned to EFE. All cultural heritage requirements have been met. | |
| Exploration | Previous exploration at the Nowa Nowa Iron Project was carried out by the Victorian |
| done by other | Geological Survey (GSV), Pickhands Mather, Australian Coal & Gold and by Gulf |
| parties | Mines Ltd. |
| To the best of EFE’s knowledge this exploration that led to the discovery of the Nowa | |
| Nowa deposit was conducted in a professional manner using recognised and widely | |
| accepted exploration and mining industry standards employed at that time. | |
| Historical reports and results of the GSV exploration and previous explorers are | |
| available on open file in the Department of PrimaryResources database. | |
| Geology | The Nowa Nowa Iron Project is situated in the Lachlan Orogen, which extends from |
| eastern Tasmania, through central and eastern Victoria, into New South Wales and | |
| Queensland. | |
| The Silurian Yalmy Group and Devonian Snowy River Volcanics host the Nowa Nowa | |
| iron ore mineralisation. They are considered to be replacement deposits of the Iron | |
| Ore Copper Gold (IOCG) style of mineralisation. | |
| The mineralisation is characterised by massive magnetite-hematite with lesser | |
| chlorite, talc/carbonates, pyrite, quartz and chalcopyrite. | |
| Mineralisation at the Five Mile prospect occurs in a zone that is up to 500m in length, | |
| 150m in width and 100m in thickness. At the Seven Mile prospect, mineralisation | |
| occurs in a discrete zone approximately 100m in length, 50m in width and up to 65m | |
| in thickness. | |
| Drillhole | A tabulation of the recent drillhole information is included at the end of this report. |
| Information | No additional exploration results have since been reported. |

| Data | A lower cut-off grade of 40% Fe has been used in the resource estimate for the Five |
| aggregation | and Seven Mile deposits. No top cuts have been applied. |
| methods | |
| Relationship | Iron mineralisation at the Five Mile prospect replaces sediments and volcanic units |
| between | which appear to be sub-horizontal or dip moderately to the southeast. Drillholes are |
| mineralisation | drilled vertically and are assumed to be close to the true width intersection of the |
| widths and | mineralisation. The geometry and attitude of the mineralisation is well constrained by |
| intercept | close-spaced drilling which has also defined a bounding fault on the western side of |
| lengths | the mineralisation. Mineralisation at Seven Mile is constrained by the current extents |
| of drillinginformation. | |
| Diagrams | Diagrams and schematics of the drilling information were presented in the_Nowa_ |
| _Nowa Resource Upgrade_announcement to the ASX on 12/06/2013. | |
| Balanced | No exploration results are reported in this release. |

| Other | Ground magnetic surveys have clearly defined the limits of mineralisation at Five Mile |
| substantive | and are used to guide drillhole targeting. |
| exploration data |
A ground magnetics survey was conducted by Gulf Mines in 2008, using two Geometrics 856 magnetometers. Lines were run east - west with a 100m line-spacing between traverses. Infill lines at 50m spacing were used over the strongest anomalies |
| at the Five and Seven Mile prospects. Measurements were recorded every five | |
| metres along each profile. Computer modelling and reporting of the ground magnetics | |
| dataset was conducted by geophysical consultant Steve Webster. A single tabular | |
| body was modelled to simulate the main anomaly at Five Mile. Strong magnetic field | |
| gradients at Seven Mile resulted in a complex modelled anomaly. | |
| Geophysical consultants Planetary Geophysics were contracted by Gulf Mines in | |
| 2009 to conduct a gravity survey at the Nowa Nowa Iron Project. Carried out using a | |
| LaCoste & Romberg Model-G gravity meter, a total of 210 stations were recorded. | |
| Computer modelling and reporting of the gravity dataset was conducted by | |
| geophysical consultant Steve Webster. The gravity models display an excellent fit with | |
| the observed data and are in agreement with the known geology and magnetic data | |
| acquired in the area. | |
| Metallurgical testwork has been carried out investigating appropriate methods of | |
| beneficiating the iron mineralisation. | |
| The large scale dry LIMS testwork was performed on composite samples on a pilot- | |
| scale dry LIMS unit at the Western Process Equipment laboratory in Perth, WA. Low | |
| grade three quarter HQ core from NDD015, NDD016 and NDD017, high grade quarter | |
| HQ core from NDD015, NDD016 and NDD017, and quarter HQ core from NDD012 | |
| and NDD014 were used for this testwork. (The detailed location of these drillholes | |
| was reported on 13 June 2013.). | |
| Five composites were made up based on head grade and magnasat. The effects of | |
| varying the drum speed with the moisture content and crush size were measured with | |
| the complete Dry LIMS tests were carried out at a drum speed of 2.5m/sec, a crush | |
| size of -6mm and zero moisture content. | |
| DTR was performed on the each of the composites at 106 μm to determine the | |
| recovery and grades achievable. This testwork was also a check on the removal of | |
| sulphur at fine sizes. | |
| Further work | Further work at the Nowa Nowa Iron Project is dependent on the results of the |
| feasibility study currently being undertaken by EFE and in consideration of other | |
| commercial aspects. |
