Announcement PDF ASX ANNOUNCEMENT RELEASED 17 SEPTEMBER 2026 1. See Appendix A - Van Uden Mineral Resource LATERITE RESOURCE GROWTH DRILLING TO COMMENCE AT VAN UDEN Focus On Expanding Near Term, Low Cost Production Opportunity Highlights ■ A shallow aircore drilling program is about to commence targeting extensions of the at surface laterite hosted gold resource at the Van Uden Gold Project. ■ The current laterite Resource at Van Uden stands at 1Mt @ 0.52g/t for 17,700 oz Au1 with recent testing returning outstanding 90%+ recoveries via simple heap leach ■ The Company is in the process of finalising a scoping study to outline the financial metrics on the heap leach opportunity, which is expected to be released shortly ■ The drilling program is designed to define additional laterite resource tonnes to increase the scale and mine life of the proposed laterite heap leach opportunity ■ Drilling is targeting an area of confirmed gold mineralisation from recent auger drilling that is approximately the same size footprint that hosts the existing Laterite Resource1 TG Metals Limited (TG Metals or the Company) (ASX:TG6) is pleased to provide an update on operational activities at the Van Uden Gold Project (Van Uden or the Project). An aircore drill rig is mobilising to site (Figure 1) and will commence drilling on the Van Uden laterite extensional targets. A total of 689 vertical drillholes are planned, totaling approximately 4,150m with ability to expand the program if needed. See Figure 2 for the target locations. The drilling program will be conducted over 21 to 28 days, testing gold bearing laterite which has previously been tested with auger drilling (ASX Announcement 9 July 2026). TG Metals CEO, Mr. David Selfe stated; “With the Scoping Study on the Van Uden heap leach being finalised, this next phase of drilling will aim to substantially increase the laterite resource and expand the life of the proposed heap leach. Combining on-site heap leach processing with off-site Ore Purchase agreements for the bulk of the defined resource, will enable the Company to realise the full potential of the Van Uden gold project whilst deploying low capital expenditure development.” A Landcruiser mounted drill rig and Morooka tracked support vehicle will be deployed to reduce ground disturbance. The short depth of the planned drillholes, approximately 6m, will be suited to the aircore drill rigs’ capability. Drilling results will go directly into resource modelling with the aim of potentially doubling current laterite resources1 as indicated by the ASX ANNOUNCEMENT I RELEASED 17 SEPTEMBER 2026 ________________________________________________________________ 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 drill target footprint shown in Figure 2 being of similar size to the existing laterite resource footprint which forms the basis of the current Scoping Study. Early-stage discussions have commenced for non-dilutive financing solutions to fund potential capital costs associated with the Van Uden Heap Leach Project. There is no certainty these discussions will result in a binding agreement.

Samples will be assayed by the Photon method and results feeding into an update of the Mineral Resource Estimate, specifically the Laterite material type. Further Flora and Fauna will be completed this spring to advance the proposed Heap Leach project. Finalisation of a definitive Ore Purchase and Profit Share agreement is advancing. Finalisation of the Scoping Study into gold Heap Leaching of the Laterite. Diamond drill core drilling at the Burmeister deposit, Lake Johnston lithium project, to conclude in September.

The surface Laterite is the current focus for heap leach technology. The updated MRE below in Table 1 shows the current resource status: Table 1: MRE – Van Uden Gold Deposit NOTES: 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. The laterite portion of the mineralisation has been reported at a cut-off grade of 0.10 g/t Au by area within a A$6,000/oz Au optimised pit shell. All other material types are reported at a cut-off grade of 0.30 g/t Au by area within a A$6,000/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 competent person to demonstrate that a mineral deposit has the potential to be economically extracted in the future Material Grade Grade Grade (Au g/t) (Au g/t) (Au g/t) Laterite 886,000 0.56 15,900 167,000 0.33 1,800 1,053,000 0.52 17,700 Oxide 1,976,000 1.15 73,300 414,000 0.91 12,100 2,390,000 1.11 85,400 Transition 1,115,000 1.07 38,300 740,000 1.01 24,100 1,855,000 1.05 62,400 Fresh 580,000 1.35 25,100 2,057,000 1.21 80,200 2,637,000 1.24 105,300 Total 4,557,000 1.04 152,600 3,378,000 1.09 118,200 7,935,000 1.06 270,800 Gold (oz) Indicated Inferred Total Mineral Resource Estimate Van Uden Gold Deposit - April 2026 Tonnes Gold (oz) Tonnes Gold (oz) Tonnes
