OPTION TO ACQUIRE TRIGG HILL LITHIUM PROJECT
Highlights
-
Eastern Iron Limited has entered into a binding Heads of Agreement with Amery Holdings Pty Ltd for an option to acquire a 100% interest in the Trigg Hill Project, which contains a number of Lithium-Caesium-Tantalum (“LCT”) pegmatites.
-
Trigg Hill is strategically located in the Shaw River district, Pilbara, that is approx. 75km SE of Pilbara’s Minerals’ (ASX: PLS) wholly-owned Pilgangoora Lithium-Tantalum mine.
-
Hundreds of pegmatite outcrops occur within the Trigg Hill - Curlew pegmatite swarms covering approximately 5km[2] and the former Trigg Hill tantalum mine with surface lepidolite and spodumene reported.
-
Eastern Iron has engaged highly respected industry veteran Mr. Mark Calderwood, who has 30 years’ exploration and mining experience including over 7 years in pegmatite minerals, as an advisor on the exploration strategy for Trigg Hill.
-
Option provides exposure to lithium in line with global focus on carbon neutrality and demand in battery chemicals for electric vehicles.
Eastern Iron Limited ACN 126 678 037 ( ASX: EFE ) ( EFE or Company ) is pleased to announce that it has entered into a binding Heads of Agreement with Amery Holdings Pty Ltd ACN 009 269 612 to acquire 100% interest in the Trigg Hill Project (E 45/5728), located in the Shaw River district, East Pilbara, Western Australia (the “ Project ”) (Figure 1).
Chairman Eddie King commented: “Lithium is boasting outstanding fundamentals on the back of electric vehicle (EV) adoption which is set to go parabolic. European stimulus packages in 2020 assisted in providing a catalyst to this growth, but as these packages expired, EV sales in Europe has displayed continued robust growth. Along with steady Chinese and North American growth, industry forecasts predict that EVs will dominate half of the total vehicle sales by 2030. On the back of this forecasted demand and with limited future supply, we expect that lithium prices will need to stay elevated to incentivise development of new lithium projects. Eastern Iron intends to gain exposure to the lithium market by acquiring the Trigg Hill Lithium Project, with known curlew pegmatites in a world class jurisdiction with nearby existing infrastructure. We are excited with the acquisition and look forward to working with Mark in developing Trigg Hill.”

Project Summary
Location and tenures
The Project is located in East Pilbara, Western Australia about 225km by road from Port Hedland. The nearest town is Marble Bar located 78km by road. The Project is adjacent to the Mont Webber DSO iron ore mine and camp (Atlas Iron), with existing mine infrastructure including roads, water bores and communications located on the Trigg Hill licence.
The Project is located approximately 75km SE of the Pilgangoora Lithium mine and 77km SE of the Wodgina Lithium and Tantalum mine. The Project is also located 80km SW of Global Lithium Resources‘ Marble Bar Lithium Project.
The Project comprises 1 Exploration Licence Application (ELA 45/5728) which covers 5 blocks. The ELA is expected to be granted in December quarter 2021.

Geology
Regionally, the Project is located within the East Pilbara granite-greenstone terrain, which is characterised by granitic rocks of the Shaw Batholith. Metamorphosed granitic rocks of the Archean Tambina, Split Rock and Callina Supersuites in the centre and southeast of the project area dominate the local geology. The granites have intruded older Archean rocks of the Pilbara Supergroup, composed of mafic and felsic volcanic rocks, with minor sedimentary and intrusive rocks. These units

underly much of the western and northern parts of the tenure. The granitic rocks contain extensive swarms of late-stage pegmatites, the source of the tin and tantalum mineralisation in the area.
The geology of the project is largely rafts of amphibolitic and chloritic schists after basalts and dolerites, with some schistose metaperidotites, meta-dunnites and komatiitic metabasalts, between variably gneissic granitoid units of monzogranite, granite, granodiorite and tonalite. Siliceous metasediment units and greisen are also mapped on the property.
Pegmatite dykes related to the various granitic plutons have been intruded into the greenstone sequences and occur in swarms. These are variably fractionated and several have been located that fall at the end of the fractionation sequence in the Lithium- Caesium-Tantalum (LCT) category.
There are two types of pegmatites in the group. The first shows cassiterite, monazite and tanteuxenite, as sub-parallel swarms less than 0.5 metres wide dykes. The second are albite pegmatites, zoned with quartz cores, and containing beryl, formanite, lepidolite, muscovite, spodumene, yttrotantalite, and zinnwaldite. The largest pegmatite exposure is described as tantalum and rare earth bearing in a 200 x 10 metre area, at Trigg Hill, with further pegmatites to the northwest.

History
The Project covers the entire Trigg Hill pegmatite swarm and the Curlew pegmatite swarm except for one excised mining lease (M 45/1267) totalling 0.22sq km, covering the Curlew emerald deposit. The history is well documented by Jacobson et al .
Trigg Hill Pegmatites
The tantalum mineral formanite was first discovered at Trigg Hill in 1906, During the 1960s, 340kg of tin-tantalum concentrates were produced. Several small pits and trenches were made in a large tantalum and rare earth bearing pegmatite. Pilgan Mining Ltd exploited in a small-scale operation eluvial and alluvial material surrounding the Trigg Hill pegmatite from 1980-82. They treated 21,000 cubic metres of material and produced an estimate ten tons of tantalum and tin concentrates. Trigg Hill is the Type locality of mineral formanite, analysis of formanite by Simpson (1948) contained 54% Ta205, 27.7% (Y, Er)2O3 1.8% Nb2O5 and 3% other REO Th, U.
Work subsequent to mining included stream sediment and soil sampling, mapping and limited rock chip sampling. Soil sampling returned strong Li and Cs anomalism associated with pegmatite outcrops and areas of interpreted soil covered pegmatite or greisen.
No drilling of the Trigg hill pegmatites has been recorded.
Ta, REO, Li Mineralogy
Jacobson et al documents the presence of tantalum-REO minerals formanite, microlite, calciosamarskite, tanteuxenite and lithium minerals spodumene, lepidolite and zinnwaldite but there is no details attributed to the record. Fresh exposures or pegmatite are limited however the LCT pegmatites are zone albite type. A single scintillometer traverse (Skotsch 1994) indicates that the LCT pegmatites may be more extensive than indicated by surface exposures, see Figure 5.

Curlew Pegmatites
The Curlew emerald deposit (excised) was discovered prior to 1940 and was mined from 1976 to 1982 with variable success.
Emeralds, beryl, scheelite and molybdenite are associated with a narrow LCT pegmatite vein. The more prospective pegmatites are the larger LCT pegmatites within the swarm that surrounds the emerald mine. These pegmatites contain formanite and cassiterite and in 2018 limited sampling by Lithium Australia confirmed the presence of lepidolite with pegmatite rock chip samples up to 2.9% Li2O (refer Table 1)
No drilling has been recorded on any of the Curlew pegmatites.

Figure 4: Curlew area with rock chip sample locations
Potential
There are hundreds of pegmatite outcrops within the greenstones within the Trigg Hill to Curlew greenstone area covering about 5km[2] , most of these are small to medium in size however potential for larger LCT pegmatite bodies particularly in areas of folded or faulted greenstones such as at Trigg Hill.
The pegmatites have potential for tantalum, REO, lithium and tin. The larger zoned LCT pegmatites will be more prospective for the presence spodumene whilst lepidolite can occur in narrow dykes.
Radiometrics (U) can be used to locate larger tantalum pegmatites within greenstone host, some indications of subsurface pegmatites already located (refer figures 3 and figures 4).

Appendix A JORC Code Table 1 for Exploration Results
Section 1 Sampling Techniques and Data
| Criteria | JORC Code Explanation | Commentary |
|---|---|---|
| Sampling techniques |
Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. Include reference to measures taken to ensure sample representativity and the appropriate calibration of any measurement tools or systems used. Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. |
Sampling to date has been early stage exploration comprising surface rock and soil samples, Rock chip samples were collected by prior explorers from surface exposures of pegmatites and ‘greisen’ Soil samples were collected from <6mm regolith by prior explorer at regular grid intervals. There has been a range of sampling techniques applied and no available quality assurance and quality control (QA/QC) documentation. However, the competent person (CP) is satisfied that the results are fit for target generation purposes. |
| Drilling techniques |
Drill type (e.g. core, reverse circulation, open- hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc.). |
Not applicable – no drilling results reported |
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed. Measures taken to maximise sample recovery and ensure representative nature of the samples. Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
Not applicable – no drilling results reported |

| Criteria | JORC Code Explanation | Commentary |
|---|---|---|
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography The total length and percentage of the relevant intersections logged. |
Not applicable – no drilling results reported |
| Sub- sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. For all sample types, the nature, quality and appropriateness of the sample preparation technique. Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. Whether sample sizes are appropriate to the grain size of the material being sampled. |
There is no detailed information sampling and preparation techniques. However, the CP considers the methods of sufficient veracity for target generation purposes. |
| Quality of assay data and laboratory tests |
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. |
XRF instruments were not used for soil or rock chip sampling. The soil and rock chip samples reported in A43234 and A93102 were analysed by Genalysis laboratory but methodology is unknown. Samples were analysed for Ag, Al, As, Ba, Be, Bi, Ca, Cd, Ce, Cr, Co, Cs, Cu, Dy, Er, Eu, Fe, Ga, Gd, Ge, Hf, Ho, In, K, La, Li, Lu, Mg, Mn, Mo, Na, Nb, Ni, P, Pb, Pr, Rb, Re, S, Sb, Se, Sm, Sn, Sr, Ta, Tb, Te, Th, Ti.

| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Discuss any adjustment to assay data. |
Not applicable – no drilling results reported Lithium results have been adjusted – original results reported for Li only – these were converted to Li2O using standard industry formula (Li x 2.153). Ta, Y, Sn, Cs have also converted to pentoxide equivalent. |
| Location of data points |
Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. |
Rock Chip and soil sample locations were taken by handheld GPS in GDA 1994 MGA Zone 50. RL (z) records are non-existent or not reliable. RL is not relevant for early-stage exploration and this information is not required for planning further exploration. |
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. Whether sample compositing has been applied. |
The data is not appropriate for use in estimating a Mineral Resource and Ore Reserve and is not intended for such use. There has been insufficient recent exploration to define a Mineral Resource and it is uncertain if further exploration will result in the determination of a Mineral Resource No sample compositing was undertaken |
| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
The rock chip samples were collected at selected sites and it is unknown if the results are biased or unbiased. The soil samples of <6mm size fraction were collect at grid intervals and it is unknown if the results are biased or unbiased. |
| Sample security |
The measures taken to ensure sample security. |
Not applicable given the nature of sampling |
| Audits or reviews |

| Mineral tenement and land tenure status |
Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
Exploration licence application 45/5728 located 78km WSW of Marble Bar in the Pilbara in the name of Amery Holdings Pty Ltd. The Company has entered into an agreement pursuant to which it has the option to purchase 100% legal and beneficial ownership of the foregoing tenement, subject to satisfying a cash payment and granting a 1.5% net revenue royalty payable to the vendor. Following completion, the Company will assume responsibility for the payment of the State Government royalty. On approval, the Company will be required to maintain the exploration licence application in good standing. The Licence application is subject to a registered native titled claim in the name of Nyamal (WC1999/008). Accordingly, access agreements are required to be completed prior to commencement of exploration. Several infrastructure miscellaneous licences held by Atlas Iron partially overlap the licence area, an access agreement has been signed between Atlas Iron and Amery Holdings. The licence application partially overlies a reserve for a potential rail line (FNA11568). |

| Drill hole Information |
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: • easting and northing of the drill hole collar • elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar • dip and azimuth of the hole • down hole length and interception depth • hole length. If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
Not applicable – no drilling results reported |
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. The assumptions used for any reporting of metal equivalent values should be clearly stated. |
For plotting purpose soil samples have been grouped and colour coded at: 0-50ppm Li2O; 50-100ppm Li20; 100-150ppm Li2O; and >150ppm Li2O |

| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’). |
Not applicable – no drilling results reported |
| Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
Figures 3 and 4 show all sample locations for the Trigg hill and Curlew prospects . |
| Balanced reporting |
Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
All soil samples and pegmatite/greisen sample locations have been shown |
| Other substantive exploration data |
Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
All relevant and material exploration data for the target areas discussed, has been reported. |
| Further work | The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling). Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
Eastern Iron Limited is planning to undertake detailed sampling within the area followed by drilling |
