Announcement PDF ASX ANNOUNCEMENT RELEASED 1 JUNE 2026 * ASX Announcement 1 May 2024, refer to Table 2 ** CIF = cost, insurance and freight to China *** ASX Announcement 16 October 2024 Mining Lease Application Lodged as Lake Johnston Lithium Project Progresses Towards Development Highlights TG Metals Limited (TG Metals or the Company) (ASX:TG6) is pleased to provide this update on its 100% owned Lake Johnston Lithium Project (Lake Johnston or the Project) in WA. The Company has applied for a Mining Lease (M63/0697) over the Burmeister lithium deposit, Figure 1. The Burmeister deposit was previously modelled from wide spaced drilling to produce an Exploration Target of 15.6Mt – 20.1Mt @ 0.97% - 1.19% Li2O (see Table 2, ASX announcement 1 May 2024). Extensive metallurgical testwork on drill core samples have defined pathways to production including the potential for a DSO product from simple crushing and ore sorting onsite at Lake Johnston. The Mining lease application advances the development potential at Burmeister with a view to taking advantage of the current high demand for DSO lithium pegmatite products. The current buoyant DSO market, with pricing now in the range of US$362/t to US$430/t CIF China for a 1.2% Li2O product, supports the development focus for the Company’s lithium assets. TG Metals CEO, Mr. David Selfe stated; “The lithium market has rapidly recovered, and TG Metals can take advantage of these vastly improved conditions via the Company’s wholly owned Burmeister lithium deposit. The Mining Lease application encompasses the Burmeister deposit and planned infrastructure that sets the Company on course for the potential early establishment of a DSO operation. The project is well located close to the port of Esperance. ■ Mining lease application lodged for the Burmeister lithium deposit ■ Burmeister hosts an Exploration Target of 15.6Mt – 20.1Mt @ 0.97% - 1.19% Li2O* ■ Direct shipping ore (DSO) opportunities emerging in WA, with the Lake Johnston Project close to infrastructure including the Esperance Port ■ Significant third party interest in the Project received from producers, corporates and industry players ■ Current high demand for DSO lithium products driven by buoyant DSO market with pricing now in the range of US$362/t to US$430/t CIF China** for a 1.2% Li2O product ■ Past Metallurgical testwork shows a +1.5% Li2O DSO product is achievable from simple ore sorting*** ■ Minimal pre-strip requirements on shallow lithium pegmatites ■ Additional drilling at Burmeister planned to advance the DSO opportunity ASX ANNOUNCEMENT I RELEASED 1 JUNE 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 Metallurgical testwork and the shallow nature of the Burmeister pegmatites support the potential for a high-grade and low-capital DSO development pathway at Lake Johnston. The development of Burmeister will occur in parallel with our primary focus of getting Van Uden gold heap leach development to first production.” Figure 1 – Location Map showing Mining Lease application over the Burmeister Lithium Deposit. ASX ANNOUNCEMENT I RELEASED 1 JUNE 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 Mining Lease Application The Company has lodged an application for a Mining Lease over the Burmeister lithium deposit with an early development case being direct shipping ore (DSO) on the back of enquiries from a number of buyers in Asia looking for offtake and the encouraging signs of other DSO operations in development in the region. Waste pre-strip costs are likely to be low as the oxidised cover over Burmeister is shallow, circa 5 metres deep. Options for haulage offsite are now being considered and evaluated. The Port of Esperance is accessible via the Norseman – Esperance highway, see Figure 3. Testwork conducted in October 2024 showed a significant upgrade to run of mine (ROM) feed when ore sorting is applied. Results previously reported 16 October 2024, are summarised in Table 1 below. The results show that a coarse +10mm size fraction with a grade average of 1.5% Li2O can be consistently achieved with first pass ore sorting. This has the potential to be applied to a simple mine- crush-oresorting to a high quality DSO product at Burmeister onsite. The fines too are a marketable product being above the benchmark 1.2% Li2O common for DSO lithium operations. Table 1: Ore Sorter results for 3 composite samples Resource Drilling The planned drilling as reported 19 May 2026, includes provision for prioritizing the first 5Mt to 10Mt in the shallowest parts of the Burmeister deposit. This will allow for early pit design work with a view to providing feed for a potential DSO operation. The shallow drilling planned will better define the thickness of overburden which is expected to be circa 5m. The drill plan includes a total of 41 drillholes for 4,809m with a combined reverse circulation (RC) and diamond drill core (DDH). Whilst product from further metallurgical testwork on the new core to be generated in this upcoming drill program can be used for DSO product specifications to potential customers, so too can the product streams from the 2024 testwork previously undertaken.

Burmeister has an Exploration Target (refer to ASX release 1 May 2024) derived from drilling conducted by the Company as per Table 2 below. Tonnes Range Low Tonnes Range High Li2O Range Low (%) Li2O Range High (%) 15.6 million 20.1 million 0.97 1.19 Table 2 – Exploration Target Range at 0.4% Li2O cutoff The Exploration Target quantity and grade is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource. The Target is based on the Company’s resource definition drilling undertaken since discovery in October 2023. The current drill hole density (spacing between holes) at Burmeister is not considered sufficient to determine a Mineral Resource.
