Announcement PDF ASX ANNOUNCEMENT RELEASED 16 OCTOBER 2024 Burmeister achieves outstanding lithium concentrate with simple DMS processing Spodumene concentrate of up to 6.31% Li2O Highlights ■ Pre-conditioning of ore feed utilising ore sorting technology achieved an increase in Lithia head-grade of 15-39% and iron rejection of 65-70% ■ Initial Heavy Liquid Separation (HLS) testwork on Burmeister lithium pegmatite supports the ability to produce a high grade, low impurity spodumene concentrate ■ Excellent DMS (Dense Media Separation) spodumene concentrate results grading up to 6.31% Li2O ■ Results provide a positive start to underpin future engineering studies and confirmatory testwork ■ On-going test work includes the application of semi-continuous DMS and flotation technology TG Metals Limited (TG Metals or the Company) (ASX:TG6) is pleased to provide preliminary results from metallurgical testwork on the Burmeister deposit, within the Lake Johnston Lithium Project in Western Australia. TG Metals CEO, Mr. David Selfe stated; “These initial sighter metallurgical testwork on the Burmeister pegmatites are outstanding and support the potential to achieve a SC6 (6.0% Li2O spodumene concentrate) concentrate utilising HLS processing technology that supports our initial assumptions “simple mineralogy equals simple processing”. As we progress Burmeister, we aim to demonstrate a mineral resource conducive to open-pit mining and simple metallurgy, providing favourable economics for a spodumene lithium hard rock mining and processing operation. A combination of Ore Sorting and HLS technology is the preferred processing method, over other more complex mineral processing flowsheets to produce a course, quality spodumene concentrate. Flotation batch testwork is progressing on the combined fines and middlings size fractions of the crushed ore, and once complete, the company will have the basis of a preliminary flowsheet which is consistent with a low capital intensity approach.” ASX ANNOUNCEMENT I RELEASED 16 OCTOBER 2024 ________________________________________________________________ Lithium Testwork Overview The Company engaged Independent Metallurgical Operations Pty Ltd (IMO) based in Western Australia, to assist in the development and support of sighter metallurgical testwork on core samples recovered from the Company’s Burmeister deposit. Testwork was progressed at Metallurgy Pty Ltd an accredited commercial laboratory located in Perth WA. The results and testwork program were also overseen by an independent consultant Michael Rodriguez, who has over 35 years of practical and technical experience in the mining, minerals processing, hydrometallurgical and pyrometallurgical industries. The research and development testwork program was developed to determine the response to commercially demonstrated hard rock lithium processing methods available for the production of spodumene concentrate, including ore sorting, HLS/DMS (Dense Media Separation) and flotation with the use of magnetic separation technology for the rejection of iron and gangue. To date the requirement to apply a mica rejection circuit has not been necessary due to the lack of micas observed within the composite samples prepared from drilled core. Below is a summary of the testwork results from drill core sample preparation, ore sorting through to the application of Heavy Liquid Separation (HLS) on the coarse fraction (-3.35mm - +1mm size fraction). The assay results from the flotation testwork on the fines component are pending as are the results of semi-continuous DMS testwork progressed at Bureau Veritas commercial facility in Perth. The initial HLS testwork results with the application of dry magnetic separation technology applied, produced quality concentrate with a lithia grade ranging from 5.34% Li2O to 6.31% Li2O from 3 drill core representative composite samples recovered from the Company’s Burmeister deposit. Table 1 below summarises the magnetic separation results and full results are provided in Table 5. Figure 1 highlighting the magnetic and non-magnetic samples, bagged, prior to assay.

Mineralised composite samples were crushed and the -10mm size fraction was screened off prior to feeding the ore sorter. The composite samples were passed through a Steinert ore sorter utilising a combination of 3D Laser and XRT sensor technology targeting first pass impurity containing basalt removal. Figure 3 below shows the Steinert ore sorter used in the testwork. Two feed sizes were tested, -40mm - +25mm and 25mm - +10mm to determine optimal ore sorting feed size. Composites size splits are as per Table 3 below expressed as weight and percentage of total composite sample.

The photographs are of samples generated in-train and are therefore incomplete. Assays of the final products for each composite sample run are shown in Table 4. The ore sorter worked exceptionally well, separating Basalt (gangue) from the pegmatite (ore feed), Figure 4 shows typical ore sorter products produced. Table 4 below shows the Ore Sorter results producing concentrates with a head grade increase to further downstream processing. The unsorted -10mm fractions were recombined with the Ore Sorter concentrates for the next stage HLS and DMS testwork. Lithia losses to the waste streams were minimal, ranging from 3.8% to 5.2% whilst the mass rejection was 14.1% to 24.4% resulting in a significant decrease in mass going forward in the process and consequent significant rejection of basalt waste.

HLS, as defined here, is a precursor bench scale test method, used to define the recommended operating window prior to progressing semi-continuous Dense Media Separation (DMS) testwork. Four (4) size fractions, 12.5mm, 9.5mm, 6.3mm and 3.35mm) and 3 heavy liquid densities, 2.7, 2.8 and 2.96g/cm3 were selected to determine the optimum size fraction and liquid densities to progress semi-continuous DMS testwork. All size fractions were wet screened to remove -1mm size fractions. The -1mm size fraction is combined with the middlings size fraction recovered from the DMS testwork prior to downstream further processing. The HLS media used was >80% lithium heteropolytungstate. Figure 5 below shows the HLS flowsheet applied to determine the optimum size fraction and heavy media solution density. Figure 5 – Flow sheet for HLS optimisation from Ore Sorter concentrate feed The optimum sizing was determined to be 3.35mm and the optimum HLS densities 2.7 and 2.96 g/cm3. These parameters were then applied to semi-continuous DMS testwork completed at Bureau Veritas.

To determine the best magnetic intensity to use, 3 gauss levels, 3000G, 5000G and 6900G were tested prior to the final 3 blended composite runs. 6900 gauss performed the best in these tests however higher magnetic intensities are possible with different equipment. Optimisation testwork is expected to reduce the Fe grade further and will be a focus for future metallurgical testwork. Table 5 below shows the results of the magnetic separation and what would be a final coarse concentrate. Note that the lithia recovery figures are for this stage process only. Table 5 – HLS results post magnetic separation * The recoveries quoted are for this stage of the process only and are not overall Li2O recoveries Observation of the “magnetic” and “non-magnetic” products shows that the highest lithia (Li2O) grade concentrate has coincident lowest iron (Fe) grade and appears to be directly related to the amount of basalt removed during the magnetic separation process. This provides encouragement that improved basalt removal could increase the concentrate grade and reduce the deleterious elements.

As spodumene is a relatively high-density mineral (>3g/cm3) compared to some of the associated gangue, the sinks contain the majority of the course spodumene as a quality spodumene concentrate. Magnetic separation was successfully applied on the HLS course spodumene concentrate this method will also be applied to the semi-continuous DMS “sinks” spodumene concentrates. The DMS processes have been completed using equipment at Bureau Veritas Laboratories and assays for each of the staged fractions are pending. Figure 6 below shows the DMS unit and the production of “floats” (waste) and “sinks” (spodumene concentrate) prior to magnetic separation. Preliminary flotation testwork on the combined fines and middlings size fractions has been progressed. Magnetic separation and de-sliming were subsequently completed on the flotation feed. Further optimisation testwork will be progressed following the release of recently completed de-sliming and magnetic separation testwork results are available.

Further flora and fauna surveys will be conducted in November over the Burmeister deposit and adjacent areas to prepare for resource development. Reconnaissance field works are continuing on regional tenements as weather conditions allow with the aim of assessing all of the Lake Johnston tenure for further lithium pegmatites. Field crews are engaged on site on an ad-hoc basis. Drilling at Lake Johnston remains suspended due to wet ground conditions. Review of site conditions and drill areas is ongoing. Whilst the priority area for Burmeister infill drilling is the southern section, it is most likely earlier access will be available on the western side of Jaegermeister, testing the potential thickening of the pegmatites. To this end a smaller drill program has been designed on Jaegermeister and will be deployed when ground conditions allow.

These examples should not be taken as limiting the broad meaning of sampling. Include reference to measures taken to ensure sample representivity 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 (eg ‘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 (eg submarine nodules) may warrant disclosure of detailed information. • Diamond Drill (DD) Core (HQ diameter) was undertaken for exploration, metallurgical and ore sorting testwork. Drill Core Exploration Sampling and Assay • DD core was sampled for assay and intervals were pre-determined by the supervising geologist based on lithology/mineralogy of the pegmatite. The core was cut into halves for TGRCD0009 and TGRCD0024 (242-250m). The remainder of the holes and intervals listed in Table 2 were cut with only quarter core submitted to the Jinning Laboratories for assay. The procedure was amended to quarter core once scope for metallurgical testwork was addressed. All samples were dispatched to Jinning Laboratories in Perth for analysis. • Samples were sorted, crushed to -10mm, dried, and pulverized to less than 75 microns. All samples were analysed by Sodium Peroxide Fusion and ICP-OES analytical process. This process involves fusion of sample with sodium peroxide in a nickel crucible at ~650 degrees. It is then dissolved in dilute hydrochloric acid and the solution generated is analysed. This process provides complete dissolution of minerals including silicates. It should be noted that volatiles can be lost at high fusion temperatures. • All assays for determination of minerlisation were analysed at Jinning Laboratories Pty Ltd. Metallurgical Sighter Testwork Sampling • All remaining DD core assayed including contact lithology were dispatched to Metallurgy Pty Ltd in Welshpool for sighter testwork.
