Announcement PDF ASX ANNOUNCEMENT RELEASED 6 MAY 2026 Van Uden Laterite Gold Targets Defined Highlights TG Metals Limited (TG Metals or the Company) (ASX:TG6) is pleased to provide this update on laterite targets at the Van Uden Gold Project in Western Australia. TG Metals CEO, Mr. David Selfe stated; “The additional laterite targets have been defined from previous soil sampling results and historical RAB (Rotary air blast) and RC (Reverse circulation drilling) along the Van Uden shear and surrounds. The targeting has shown the potential to double the current laterite resource should planned drilling be effective in defining surface laterite gold mineralisation. Additional laterite gold will support an extended mine life for a proposed onsite heap leach operation at Van Uden. In addition, the approvals process for the laterite heap leach project has been advanced with a preliminary design created which will form part of the mining proposal submission.” Laterite Gold Targeting TG Metals has interrogated the available soil sample data and historical drilling with the existing laterite resource model (MRE)* to generate targets with a similar soil anomaly to the existing MRE (Desktop Study). Figure 1 shows the existing MRE overlaid with soil anomaly contours. In areas of available historical drill data, the anomalies were verified with laterite present. Areas without historical drilling will be drill tested with RC drilling. Programs of Work (POWs) have been submitted for this drilling and await approval. The addition of further laterite mineralisation will extend the mine life of the heap leach project further enhancing economics. All the defined laterite gold targets lie within existing Mining Leases and close to existing internal haul roads. *See Table 1 ■ Desktop study defines additional laterite gold targets ■ Potential to double laterite gold resources ■ Approvals underway for first drilling of these targets ■ Preliminary heap leach design to underpin Mining Proposal ASX ANNOUNCEMENT I RELEASED 6 MAY 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 Figure 1 – Existing Laterite MRE and Generated Targets ASX ANNOUNCEMENT I RELEASED 6 MAY 2026 ________________________________________________________________ 3 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 Heap Leach Design TG Metals has created a preliminary design for the laterite heap leach project. The design is based on an on-off leach pad production model with the intention of minimizing the disturbance footprint of the heap leach pads and infrastructure. This design will be included in the mining proposal to be submitted this month for approval. Further modifications may be necessary upon completion of the heap leach metallurgical testwork however the overall disturbance footprint should not alter significantly. Figure 2 below shows the preliminary design rendered in 3D. The design sits within the starter laterite pit which will reduce the overall footprint of the disturbance area. The design includes adequate areas for all proposed infrastructure, leach pads and run of mine (ROM) storage. The design has been based on a nominal 250,000 tonnes per annum capacity.

Final recovery and reagent use will be available upon completion. Mining Proposal to be submitted. Drill testing of the additional laterite targets to commence upon POW approvals. Heap leach equipment sourcing has commenced. Discussions with suitable mining contractors has commenced. About The Van Uden Resource The Van Uden gold MRE was updated in April 2026, increasing the Indicated category by more than 120%. This has allowed progression of mining and processing studies focused on utilising the Indicated resources in the near term. The surface Laterite is one component of this and the most immediate potential, however further Indicated resources deeper in the profile may also lend themselves to Heap Leach processing 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 5 ASX ASX ANNOUNCEMENT I RELEASED 6 MAY 2026 ________________________________________________________________ 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 About TG Metals TG Metals is an ASX listed company focused on exploring and developing gold and lithium assets at its wholly owned Lake Johnston Project and 80% owned Van Uden Gold Project in the stable jurisdiction of Western Australia.
