• Wedge hole ZS187W1B intersected a 25m wide zone of tin mineralisation including a high-grade core of 4m @ 1.26% Sn
• Results support continued resource conversion of the Heemskirk tin system with expectations to upgrade from Inferred to Indicated
• Two additional wedge holes have been completed and a third is underway to further test the mineralisation

Stellar Resources Limited (ASX: SRZ) is pleased to report further drilling results from the Severn deposit at its Heemskirk Tin Project in Western Tasmania. The recently extended drilling program comprises a total 29-hole (~12,000m) diamond drilling campaign focused on infill and extensions to the 2023 Mineral Resource Estimate (MRE). This release reports assay results from one wedge hole drilled at Severn (ZS187W1B). The hole targeted an area of tin mineralisation within the Inferred category of the MRE, with the goal of enabling resource conversion of mineralisation to the Indicated category. The hole intersected a significant 25m wide zone of tin mineralisation including a high-grade core of 4m @ 1.26% Sn from 546m, including 2m @ 1.92% Sn. The results support the continued resource conversion of the Heemskirk tin system with high expectations to upgrade from Inferred to Indicated whilst expanding the 2023 MRE. A second wedge hole (ZS187W1C) has been completed to further test the mineralisation, with assays pending, and a third wedge hole (ZS187W2) is now underway targeting 45m south of the parent hole ZS187. The Company anticipates reporting updated Resources at Queen Hill and Severn in 2H 2025 and the completion of the Prefeasibility Study in the 1H 2026.

The Company is continuing momentum on site with further wedge holes planned, including holes targeting deeper tin intersections at Severn. The recent spike in tin prices highlights the strategic importance of Stellar's Heemskirk Tin Project, and the Company is focused on growing and de-risking the deposit to create significant value for shareholders.
