Announcement PDF ASX ANNOUNCEMENT RELEASED 25 SEPTEMBER 2025 SECOND DRILL RIG ARRIVES AS TRANSFORMATIONAL DRILLING PROGRAM TO EXTEND VAN UDEN RESOURCE COMMENCES Highlights ■ Second drill rig arrives on site at the Van Uden Gold Project to commence resource extensional drilling ■ Resource extensional drilling is initially comprising 41 shallow drillholes for approximately 2800 metres, with up to an additional 150 deeper drillholes to be added ■ First large scale drilling for gold at the Project since 2011/2012 providing significant potential to grow the existing Resource1 at Van Uden which remains open along strike and at depth ■ Recent exploration results have more than doubled the mineralised strike at Van Uden to 6.5kms, providing multiple new growth targets outside of the existing Resource1 ■ Gold City Project maiden drilling also in the current drill campaign TG Metals Limited (TG Metals or the Company) (ASX:TG6) provides an update on exploration activities at the Van Uden Gold Project (Van Uden). Resource definition drilling underway within the historic Tasman Pit is progressing well and expected to be completed within the next 7 days. (Figure 1). A second drill rig has arrived on site to commence testing under-drilled internal and extensional positions within the 2.5 kilometre long Van Uden gold deposit (Figure 2). This drilling is expected to extend and improve the strike and depth continuity of the resource. The second rig will initially complete shallow drill holes (less than 110m) at Van Uden, before being deployed to the maiden drilling program at the Gold City geochemical anomalies (ASX announcement 7 August 2025). Figure 3 shows the planned initial shallow drilling at Van Uden and Figures 4 and 5 show typical cross sections targeting previously undrilled areas of the Van Uden Gold Deposit. The aim of this drilling is to: 1. Expand the modelled extents of shallowest parts of the Van Uden resource; and 2. Improve the Van Uden resource classification by converting Inferred resources to Indicated. Deeper drilling, to test depth extensions of the Van Uden gold deposit, will commence as soon as the drilling contractor can supply a larger capacity RC drill rig. Drill sites at the Gold City Prospect have been prepared, with drilling to be scheduled in with the shallow RC drilling completed at Van Uden. 1. See Table A “Van Uden Gold Project Description” ASX ANNOUNCEMENT I RELEASED 25 SEPTEMBER 2025 ________________________________________________________________ TG Metals CEO, Mr. David Selfe stated; “Our recent capital raising has allowed us to accelerate the drilling onsite at Van Uden. Ultimately we want to be in a position as soon as possible to understand the full potential of this large gold system, leading onto a substantial update of the MRE early in calendar 2026. The first drilling at the Gold City prospect is also important, as we explore for satellite deposits, in tandem with advancing the Van Uden deposit towards first mining studies. We look forward to updating investors with our drilling progress and reporting first assays from this current programme.” Figure 1 –Drill Rig One Drilling in Tasman Pit 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 2 ASX ANNOUNCEMENT I RELEASED 25 SEPTEMBER 2025 ________________________________________________________________ Figure 2 –Drill Rig Two arrives onsite at Van Uden 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 3 ASX ANNOUNCEMENT I RELEASED 25 SEPTEMBER 2025 ________________________________________________________________ Figure 3 –Van Uden Resource Infill and Extensional Planned Drilling 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 4 ASX ANNOUNCEMENT I RELEASED 25 SEPTEMBER 2025 ________________________________________________________________ Figure 4 –Van Uden Resource Infill and Extensional Planned Shallow Drilling Over Interpreted Mineralisation Wireframe Figure 5 –Van Uden Resource Infill and Extensional Planned Shallow Drilling Over Interpreted Mineralisation Wireframe 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 5 ASX ANNOUNCEMENT I RELEASED 25 SEPTEMBER 2025 ________________________________________________________________ Follow-up Work Additional POW applications for drilling on the Van Uden shear, testing additional gold in soil anomalies recently identified (ASX announcement 9 September 2025) is progressing with the aim of timing execution whilst the drill rigs are onsite. These new gold in soil anomalies have more than doubled the known strike length of mineralisation at Van Uden. Infill soil sampling at Gold City has commenced with the aim of increasing gold in soil anomaly definition on the wider spaced soil results reported on 7 August 2025. Van Uden Gold Project Description The Project is located on the Forrestania Greenstone Belt, Figure 6, 90km east-northeast of Hyden and 120km south of Southern Cross. 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.

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.
