• Wedge hole ZS187W2B intersected significant tin mineralisation, including 12.6m @ 0.83% Sn from 611m with a high-grade zone of 2.9m @ 3.00% Sn
• Results support continued resource conversion and expansion of the Severn Deposit as part of the Heemskirk Tin Project
• Stellar's total Mineral Resource now exceeds 100kt of contained tin across its Heemskirk Tin Project and nearby St Dizier satellite deposit

Stellar Resources Limited (ASX: SRZ) is pleased to report further drilling results from the Severn deposit at its Heemskirk Tin Project in Western Tasmania. Wedge hole ZS187W2B intersected several zones of significant tin mineralisation, including 22.0m @ 0.45% Sn from 479.7m and 10.0m @ 0.88% Sn from 526m. Significantly, the hole was extended beyond the planned depth and intersected a new zone of mineralisation approximately 60m below the existing Resource model, returning 12.6m @ 0.83% Sn from 611m including a high-grade zone of 2.9m @ 3.00% Sn. These results support the continued resource conversion of the Severn Deposit as part of the Heemskirk tin project, with high expectations to upgrade material from Inferred to Indicated while expanding the 2023 Mineral Resource Estimate. The Heemskirk Tin Project continues to rank as the highest-grade undeveloped tin project in Australia and the third highest-grade globally. Stellar anticipates reporting updated Resources for the Severn deposit and completion of the PFS in Q2 2026.

Stellar is rapidly working towards upgrading the Severn Resource in Q2 2026, which will serve as a strong foundation as the company advances its development studies amid the tightening global tin market.
