Additional A$500,000 placement to advance Heemskirk

Stellar Resources Limited (ASX: SRZ, “Stellar” or the “Company”) is pleased to advise that the Board has approved an additional equity placement “ Additional Placement ” to an existing Substantial Shareholder of the Company.

The Additional Placement comprises of 22,727,273 shares at an issue price of $0.022 per share, for a total of $500,000.

The Additional Placement was completed under the same terms as the A$9 million Placement announced on 11 November 2025 and will be settled via the same single tranche within the Company’s existing capacity under ASX Listing Rule 7.1.

Stellar’s cash position has been recently further boosted by the exercise of unlisted options raising $2.9 million and now combined with the Placement and the Additional Placement, the Company has successfully raised a total of $12.4 million in the past few months, supported by prevailing strong investor appetite for tin exposure.

Placement proceeds will be targeted towards development and exploration costs at the Heemskirk Tin Project in Western Tasmania, general working capital and the costs of the offer.

• Tin prices are trading around US$36,000/t[1] , underpinned by strong electronics and renewable energy demand and intensified by supply disruptions in key producing regions, reinforcing investor interest in new tin supply from conflict-free, tier-1 mining jurisdictions.

About Stellar Resources:

Stellar Resources ( ASX: SRZ ) is highly focused on developing its world class Heemskirk Tin Project located in the stable tier-1 mining friendly jurisdiction of Zeehan, Western Tasmania and aims to become a producer of 3,000 – 3,500tpa of payable tin, approximately 1% of global supply[#] . The Company has defined a substantial high-grade resource totalling 7.48Mt at 1.04% Sn, containing 77.87kt of tin (3.52Mt at 1.05% Sn, containing 36.99kt of tin classified as Indicated and 3.96Mt at 1.03% Sn, containing 40.88kt of tin classified as Inferred)*. This ranks the Heemskirk Project as the highest-grade undeveloped tin resource in Australia and third globally.

Aiming to become a producer of 3,000 to 3,500 tpa of payable tin is an aspirational statement and SRZ does not have reasonable grounds to believe the statement can be achieved.

Prefeasibility activities underway are evaluating potential project optimisations that will enable a boost in tin output from the 2024 Scoping Study. These activities include resource and exploration drilling to increase confidence by upgrading and expanding resource classifications as well as ore sorting test work to increase ore feed head-grade and tin recoveries.

Stellar also holds the highly prospective North Scamander Project where initial drilling in September 2023, intersected a significant new high-grade silver, tin, zinc, lead and Indium polymetallic discovery.
