Announcement PDF ASX ANNOUNCEMENT RELEASED 18 NOVEMBER 2025 Gold Drilling Results from Van Uden Continue to Impress Highlights TG Metals Limited (TG Metals or the Company) (ASX:TG6) is pleased to provide the results from the ongoing drilling at the Van Uden Gold Project (Van Uden or the Project). These results are from the shallow reverse circulation (RC) drillholes in the central and southern areas of the Van Uden gold deposit (Figure 1), targeting resource expansion and geological understanding between previous drill lines and down dip. Many holes intersected multiple gold zones in each drillhole. Result highlights include: • 8m @ 2.74 g/t Au from 32.0m, including 3m @ 3.96 g/t Au • 4m @ 1.36 g/t Au from 45.0m and 8m @ 0.90 g/t Au from 52.0m and 5m @ 1.57 g/t Au from 70.0m • 4m @ 1.01 g/t Au from 55.0m and 5m @ 1.60 g/t Au • 5m @ 1.13 g/t Au from 30.0m • 4m @ 0.60 g/t Au from 33.0m and 6m @ 0.97 g/t Au from 39.0m TG Metals CEO, Mr. David Selfe stated; “Drilling results continue to come in for the shallow drilled parts of the Van Uden deposit as we continue with drilling the down dip extensions. Although these new drillholes are shallow, some have drilled beyond the limits of the current MRE. We are now drilling even further down dip, with several assays pending for drillholes collared on the eastern edge of the conceptual pit shell. The push is on to get as much drilling as possible done ahead of a planned update of the MRE in early 2026. Gold City drilling results should be out of the laboratory shortly and we can add those assay results to the downhole telemetry data.” ■ Drill assays returned from the central and southern areas at Van Uden ■ High tenor results include: ■ 8m @ 2.74 g/t Au, including 6m @ 3.96 g/t Au ■ 5m @ 1.57 g/t Au, including 3m @ 1.82 g/t Au ■ Adding gold ounces to the current MRE continues to be the focus ■ Drilling to test depth extensions is ongoing and progressing well ■ Approvals granted to drill first areas outside and along strike of the existing mineral resource ASX ANNOUNCEMENT I RELEASED 18 NOVEMBER 2025 ________________________________________________________________ 2 TG METALS LTD ASX TG6 ABN 40 644 621 830 Level 2, Suite 3 28 Ord Street West Perth WA 6005 T: +61 8 6211 5099 W: www.tgmetals.com.au Van Uden Drilling The ongoing purpose of this drilling campaign is to expand on the current Van Uden mineral resource estimate (MRE) via infill and down dip extensions and provide data to improve geological understanding. These results are from the central and southern parts of the Van Uden deposit, Figure 1 shows the location of the drillholes.

The full significant assay results above 0.3g/t Au are provided in Table 2. Figure 2 – Cross Section A-A’ Showing New Drilling, Historical Drilling and Van Uden Mineralisation Envelope The RC drilling was conducted with a truck mounted Hydco-Moses drill rig. This rig is suitable for shallow drilling (-110m) in the oxidised to semi-oxidised regolith. A total of 16 drillholes are included in this report for 1086m of RC drilling. The drillhole dips are all -60o at an azimuth of 250o to align with the previous historical grid. See Table 1 for drill collar information. The reported drilling is in the central and southern areas within the vicinity of the current MRE. Additional drilling has been completed throughout the resource area with assay results pending. See Figure 1 for drill collar locations. As per previous recent drilling, individual 1m samples were assayed using the Photon assay technique, which utilises a larger sample charge than fire assay. This has the potential to reduce the “nugget effect” caused by coarse gold particles. Several drillholes recorded multiple gold mineralised intercepts, refer to Table 2. Most were anticipated from previous adjacent historical drilling however new positions based on a reinterpretation of flat fault mineralisation and small displacement mafic hosted mineralisation down dip were also confirmed, see Figure 2. Mineralisation remains open down dip in these locations and plans are underway to further test these gold zones at depth.

Currently a large capacity RC drill rig is drilling positions targeting down dip extensions which have not previously been drilled. Assays are pending for the maiden exploration drilling program recently completed at the Gold City prospect, 20km south of the Van Uden resource area. Assays are also pending for several drillholes at the Van Uden deposit, Figure 1 shows the collar locations of drilling with pending assays in this area. A further programme of work (POW) has been approved for drilling along strike and outside of the Van Uden MRE influence. This drilling will be undertaken once drill pad clearing has been completed.

It is close to the Marvel Loch (producing) and Westonia - Edna May (care & maintenance) gold processing Plants and is 130km from the Company’s established Burmeister lithium deposit at the Lake Johnston Project. Van Uden Gold consists of an Indicated and Inferred Mineral Resource as per Table A below on four granted mining leases, four granted exploration licences, one exploration licence application and two miscellaneous licences (for haul roads). The Project lies to the west of the Mt Holland lithium mine, south of the operating Marvel Loch gold Plant, and southeast of the Edna May gold Plant. Table A: MRE – Van Uden Gold Deposit The Mineral Resources statement conforms to the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC Code) 2012 Edition. All tonnages are dry metric tonnes. It has been reported at a cut-off grade of 0.35 g/t Au by area within a A$5,000/oz Au optimised pit shell based on mining parameters and operating costs typical for Australian open pit extraction deposits of a similar scale and geology. Minor discrepancies may occur due to rounding of appropriate significant figures. The resources comply with the Reasonable Prospects for Eventual Economic Extraction (RPEEE), a key principle in mineral resource reporting that requires the qualified person to demonstrate that a mineral deposit has the potential to be economically extracted in the future.

(Criteria in this section apply to all succeeding sections.) Criteria JORC Code explanation Commentary Sampling techniques • Nature and quality of sampling (eg 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 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. • All holes were sampled at 1 m intervals using an on-board Ox Cyclone Sampling system with fixed cone splitter engineered for the rig. • Two samples (Original + Duplicate) were collected each metre, representing 12.5 % of total cyclone discharge per split. • Certified reference materials (CRMs) were inserted every 20 samples, and coarse blanks every 40 samples. All samples were dry. • Samples were transported to Laboratory: SGS Australia Pty Ltd, Kalgoorlie WA (17 Stockyard Way) for PhotonAssay™ PAAU02, two-cycle analysis on pulverised material. 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). • Reverse-circulation (RC) drilling was undertaken using a Hydo Moses truck mounted rig (JDC Drilling, Southern Cross WA) The rig was equipped with a: o face sampling pneumatic hammer, o ELGI 350 PSI, 900cfm Compressor o 700 PSI @ 1400 CFM Hurricane auxiliary booster o KL remote rod handlerT, and o TJM hands free break out system. 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. • Sample recovery was visually assessed and recorded by comparing the two splitter outputs each metre. • All samples were dry with negligible loss. • Given the dry conditions and fixed splitter configuration, no material bias is expected. 2 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. • RC drill cutting of the metre interval was sieved and placed into a chip tray for geological logging and future reference. Clay intervals in regolith were not sieved, however any remnant rock/hard material were sieved and washed for identification. • TG Metals Limited geological logging system: o Recognises fresh rock vs regolith. o Is both qualitative and quantitative. o Industry and geological standards were followed recording every detail observed. o Every interval (m) drilled was logged. o 20m interval Chip trays were labelled and used to store a small representative sample for future reference. 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. • No core • Samples were split at the rig using a fixed cone splitter, producing two by 12.5 % sub-samples per metre. • All samples were transported to SGS Kalgoorlie for preparation and PhotonAssay™ analysis. • Laboratory preparation (SGS Kalgoorlie) included: o Drying at 105 °C (< 3 kg) — G_DRY o Crushing 90 % < 3.35 mm — G_CRU_KG o 500g PhotonAssay™ jar filled from crushed material • Sample weights were recorded by SGS on receipt. o CRMs and blanks returned results within expected limits. o Field duplicates retained but not yet analysed. • Sample sizes are considered appropriate to mitigate coarse gold effects 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. • Laboratory: SGS Australia Pty Ltd, Kalgoorlie WA (17 Stockyard Way). Method: PhotonAssay™ PAAU02, two-cycle analysis on pulverised material. o Charge weight: 500g Detection limit: 0.03 ppm Au – 350 ppm Au (over-range PAAU02H, 100 – 3500 ppm Au). o Preparation: drying, crushing (90 % < 3.35 mm) prior to jar fill. o Precision may be reduced in samples with elevated U, Th or 3 Criteria JORC Code explanation Commentary • 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. Ba. • No umpire analyses to date. Lab blanks and standards used. 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. • All assays reviewed and verified internally by TG Metals geological personnel prior to import into the master database. • No twinned holes were drilled. However holes were drilled in proximity to historical drillholes for comparative and additional data. • Field data entry and office validation. • No adjustments to assay data 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. • Coordinate system: MGA94 Zone 50. • Collar survey: GPS (+/- 3m accuracy). DGPS at conclusion of the program • Downhole survey: CHAMPS north-seeking gyro (continuous mode) – manufactured by Downhole Surveys Pty Ltd • Topography: LiDAR surface model. 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. • Spacing considered appropriate for the resource infill drilling campaign. • The drilling data will be used to update the current reported MRE (Table A of the report) • Assays reported on 1 m intervals; no compositing applied. 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. • Mineralisation is interpreted as shear- and vein-hosted along local contacts; • Drilling orientations are appropriate
