• Prefeasibility Study activities continue with promising metallurgical, mining and ore sorting studies
• Drilling success at Severn and Queen Hill deposits expands resources and confirms growth potential
• Large-scale ore sorting trials demonstrate significant potential to upgrade feed grade and lower processing costs

Stellar Resources Limited has reported strong results for the September 2025 quarter, with key achievements centered around ongoing Prefeasibility Study activities aimed at advancing the Heemskirk Tin Project towards development. The company's drilling success at the Severn and Queen Hill deposits continues to validate the scale and continuity of the mineralized system, prompting an expanded program to capture further upside. Recent high-grade intersections at Severn, including 10.2 metres at 1.68% tin within a broad 64-metre mineralized zone, highlight the significant potential for resource growth ahead of upcoming Mineral Resource updates. Importantly, large-scale ore sorting trials have confirmed a pathway to higher head grades and lower processing costs, with results supporting the inclusion of ore sorting within the Prefeasibility Study and further strengthening the project's development case. Stellar has also extended its Memorandum of Understanding over the nearby Comstock site and signed a new MOU over the Avebury processing facility, positioning the company to optimize development optionality for Heemskirk. Regionally, the scale of the mineralized system emerging at East Renison and the addition of the Granite Tor licence continue to build Stellar's footprint across Tasmania's world-class tin province. With strong tin market fundamentals, tightening global supply, and a solid cash position, Stellar is well-positioned to advance Heemskirk towards development and establish itself as a leading Australian tin producer.
