• Heemskirk Tin Project Prefeasibility Study activities progressing well with positive drilling and metallurgical results
• Exceptional surface sampling results at East Renison highlight emerging polymetallic potential
• Granite Tor licence acquired to further consolidate Stellar's position in Tasmania's premier tin province

Stellar Resources Limited (ASX: SRZ) has reported on its key activities during the December 2025 quarter, with a focus on advancing the Prefeasibility Study (PFS) for the Heemskirk Tin Project. The expanded infill and extensional diamond drilling program at the Severn deposit continued to deliver highly encouraging results, with wedge holes intersecting significant tin mineralisation, including 51.4m @ 0.55% Sn and 25m @ 0.38% Sn. These results support the potential for continuation and growth of the Heemskirk tin system, with the company expecting to upgrade and expand the 2023 Mineral Resource Estimate in early 2026. Positive metallurgical results were also achieved for the Severn deposit, with strong tin recoveries and clean concentrate quality, supporting the potential for a premium, unencumbered product from a Tier-1 jurisdiction. Beyond the Heemskirk project, the company reported exceptional surface sampling results at the East Renison project, highlighting the emerging scale and polymetallic potential of the broader system. Stellar also announced the acquisition of the Granite Tor licence, further consolidating its position across Tasmania's premier tin province. The company's cash position was boosted by a successful capital raising, positioning it well to maintain development pace and capture value as it progresses Heemskirk towards key milestones in 2026.

The company is aiming to become a producer of 3,000 - 3,500 tonnes per annum of payable tin, which is approximately 1% of global supply. This is an aspirational statement, and the company does not have reasonable grounds to believe this can be achieved.
