The drilling also tested extensions at depth below the DSO pit shell previously defined for the maiden Mineral Resource Estimate (See Table 2). Mineralised pegmatite was successfully intercepted down dip the MRE at interpreted pegmatite positions, see Figures 2 and 3. This drilling proves the current interpretation and lends weight to the expansion of the MRE via further infill drilling. Drill hole DSO002 intercepted particularly strong sections of pegmatite displaying individual grades above 2% Li2O throughout. Any internal dilution consisted of thin, typically less than 1m, sections of pegmatite displaying increased feldspar content and subsequent reduced lithium content, however as these are less than mineable widths their inclusion in intercepts has minimal dilution effect. The drilling also aimed to identify the oxidation boundary above which lithium is depleted in the pegmatite above the oxidation boundary. The boundary proved variable with sections of upper pegmatite with spodumene preserved whilst other parts at the boundaries were depleted. Further close spaced shallow drilling will be required to better define this boundary for grade control and mine design purposes. Drill hole DSO006 was only drilled into shallow pegmatite, less than 52m depth and subsequently intercepted weathered and depleted pegmatite. Definition of the oxidation boundary will assist with future mine design. The pegmatite intercepts were composited into 6 samples for supply to potential offtake and financing partners. All composites exceeded the nominal 1.2% Li2O criteria without the need for ore sorting.

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 Diamond Drill (DD) Core (HQ3 diameter) logged as pegmatite was sampled at intervals pre-determined by the supervising geologist based on spodumene content and obvious mineralogical crystallisation zonations within the logged pegmatite. All core was cut and only quarter core of the interval submitted for assay. Half core was composited into samples for DSO customer test work. Quarter Core was retained in trays for future reference. DD core samples were sent to Jinning Laboratories for Peroxide Fusion (Ni-crucibles) ICP-OES/MS 21 Element Scan. All DD samples were submitted to Jinning Laboratories. TG Metals Limited inserted sample blanks and lithium standards following TG Metals Limited QA/QC procedure. Sample blanks (yellow sand) were inserted at every 50th sample interval. TG Metals Limited purchased 4 x Lithium Standards from Geostats Pty Ltd that were placed in the sequence at every 25th sample interval. Duplicate sampling will be completed on quarter core at intervals selected based on grade range. Jinning Laboratories included and reported their own lithium standards, blanks and pulp replicates at rates compliant to industry standards. Certified Laboratory Assays – Jinning Laboratories Pty Ltd. Diamond Drill Core (HQ3) was orientated at the drill rig and the line drawn with paint marker. The core was placed into labelled trays at the drill site. Trays were transported from the drill site to the core-yard at Galt Discovery Center in Leederville for logging, photography and cutting. DD core was cut in half, 30 degrees from the orientation line 2 Criteria JORC Code explanation Commentary problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. and half into quarter core. Quarter core submitted for assay, was cut into sample intervals pre-determined by the supervising Geologist. As mentioned previously, sampling intervals were based on obvious crystallisation zonations within the logged pegmatite rock unit. These intervals of quarter HQ core were placed into labelled calico bags for dispatch to Jinning Laboratories in Perth for assay. All DD core samples at Jinning Laboratories were sorted, crushed to - 10mm, dried, and pulverized to less than 75 microns. All samples were analysed using Sodium Peroxide Fusion and ICP-OES analytical process where 0.25g of sample was fused in a furnace (~650 deg) with Sodium Peroxide in a nickel crucible. The melt was dissolved in dilute hydrochloric acid and the solution analysed. This process provides complete dissolution of minerals including silicates. It should be noted that volatiles can be lost at high fusion temperatures. Drilling techniques • Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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). Core samples for assay were obtained from a diamond drill rig owned and operated by Raglan Drilling Pty Ltd using Rig 001. HQ3 was the core size. The diamond drill process is a type of core drilling in which a rotary drill and a diamond drill bit cut the rock to deliver a core sample. The HQ core is removed from the inner tube of the drill rod and placed in a labelled core tray with depth and recovery markers (% of core recovered) The diamond core was orientated at the rig using an inbuilt electronic orientation tool indicating the in-situ position of the core. The orientation line was annotated using a paint pen and marker blocks clearly labelled depth intervals. The driller is also experienced in determining core orientation in the event of tool failure. 3 Criteria JORC Code explanation Commentary 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. DD core recovered was visually checked by the driller to ensure core was obtained for each metre interval drilled. Any loss or friable core was noted by block markers and addressed with the supervising geologist. The estimated value (recovery) was recorded in the geological log sheet. Drilling used HQ triple tube, where the 3rd tube is specifically engineered to retain and hold core in weathered and broken ground with minimal core loss No grade bias or poor sample recovery was observed with DD core samples. 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. TG Metals Limited geological logging system: • Recognises fresh rock vs regolith. • Is both qualitative and quantitative. • Industry and geological standards were followed recording every detail observed. • Every interval (m) drilled was logged. • DD core was orientated to ensure all structural measurements using the ezy logger tool (contacts, deformation orientations) were made in reference to the orientation line. • All core intervals were measured against depth markers using a tape measure and recorded in the geological log sheet. • All core has been photographed for future reference. • Quarter HQ core was submitted for assay. Half of the remaining core will be submitted for metallurgical test work and the remaining quarter core submitted for duplicate sampling and retained for future reference. Sub- sampling techniques • If core, whether cut or sawn and whether quarter, half or all core taken. Diamond core (HQ) was cut in half at 30 degrees from the orientation line. The half core with the marked orientation line was placed back into the tray, while the other half cut into quarters. A quarter of the core was then measured and cut into sample intervals as instructed by the 4 Criteria JORC Code explanation Commentary and sample preparation • 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. supervising geologist. n/a The quarter core cut on site was inspected by supervising geologist to ensure the intervals were cut to defined intervals before being placed in labelled calico bags to be dispatched to Jinning Laboratories. TG Metals Limited QA/QC, blanks, standards and sample duplicates are assessed by the exploration manager as data is received. No outlier results or trends have been plotted or analysed to indicate any sampling bias. Duplicate sampling will be completed after initial assay results are received. Sample duplicates will cover intervals of mineralisation to ensure a desired spread of grade bins are achieved for QAQC checks, statistics and grade variability. Sample size was considered appropriate for the lithology. 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, Jinning Laboratories is a Certified Analytical Laboratory. Samples analysed for 21 multielement Sodium Peroxide Fusion and ICP-OES analytical process were fused in a furnace (~ 650 ºC) with sodium peroxide in a nickel crucible. The melt was dissolved in dilute hydrochloric acid and the solution analysed. This process provides complete dissolution of most minerals, including silicates. Volatile elements were lost at the high fusion temperatures. Jinning Laboratories recommended this analytical process for lithium mineralisation based on internal studies and external academic research. North seeking downhole Gyro was used to obtain hole drift orientation. 5 Criteria JORC Code explanation Commentary 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 (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. The tool was calibrated as per operating procedure. Downhole data was recorded every 5m and provided to TG Metals Limited in digital format to be uploaded into the Micromine database by the supervising geologist. TG Metals Limited inserted a sand blank at every 50th sample and bought lithium standards at every 25th interval for samples submitted. Jinning Laboratory included their own lithium standards, blanks and replicates at rates compliant to industry standards. These were reported and uploaded into TG Metals Limited micromine database to be referred and used for internal QA/QC reporting. 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. Significant assay intersections were determined by the presence logged spodumene in core and >1.0% Li ppm assay results. No dedicated twin holes were part of theis program. Holes DSO003, DSO004, DSO005 were all drilled from the same collar location and varied in dip, which are not considered to be twinned holes. All primary logging and assaying data was recorded on a MS Excel worksheet (geological log) and loaded into Micromine for validation. Data is retained as a flat table in the Micromine Database. The original MS Excel spreadsheet have been retained. Micromine and server backups are completed weekly. All reported assay data were imported into the TG Metals Limited micromine database. Jinning Laboratories measure and report lithium as Li ppm and as the oxide Li20%. Location of data points • Accuracy and quality o
