Astral Resources NL (ASX: AAR) (Astral or the Company) is pleased to announce that its wholly- owned subsidiary, Mandilla Gold Pty Ltd, (Mandilla) has executed a Land Use Agreement with the Marlinyu Ghoorlie Native Title Claim Group (Marlinyu Ghoorlie). The Agreement covers the Mandilla and Spargoville tenements located 70km south of Kalgoorlie. The Land Use Agreement signed with Marlinyu Ghoorlie outlines a cooperative framework for reconciliation, cooperation and partnership between the Marlinyu Ghoorlie and Astral to develop and conduct their relationship in the spirit of goodwill, mutual respect and mutual recognition of their respective interests. The purpose of the agreement is to: • Facilitate ongoing engagement between Astral and Marlinyu Ghoorlie in relation to the conduct of Mandilla’s activities, including protocols for heritage surveys, activities to protect identified sites and clearance procedures to facilitate mining activities; • Minimise the impact of Astral’s activities on heritage sites in the Agreement area; • Provide opportunities for members of the Marlinyu Ghoorlie People to participate in Mandilla’s activities; and • Provide compensation benefits to the Marlinyu Ghoorlie People for the effect on native title of the grant of the project rights and conduct of future mining and exploration activities on the tenements. The Land Use Agreement governs the relationship between the Marlinyu Ghoorlie and Mandilla. It provides a path forward for the completion of the Mandilla DFS and a strong foundation for Astral to progress the responsible development of the Mandilla Project. 2 astralresources.com.au ASX: AAR | In May 2025, Astral announced a Mineral Resource Estimate (MRE) of 3Mt at 1.4 g/t Au for 139koz of contained gold1 for the Spargoville Gold Project.

Astral Resources’ Managing Director Marc Ducler said: “Astral is delighted to have further cemented its strong and collaborative relationship with the Marlinyu Ghoorlie People, with this Land Use Agreement providing a clear framework to protect Aboriginal Cultural Heritage and formalise Marlinyu Ghoorlie’s participation in the development of the Mandilla Project. “Importantly, following the signing of an agreement over the Feysville Gold Project with the Marlinyu Ghoorlie in October last year, all tenements incorporated in the ongoing Mandilla DFS are now covered by Land Use Agreements. “With Astral now setting its sights on finalising the Mandilla DFS, gaining the necessary mine development approvals and transitioning into mine development, the Company is committed to continuing to work closely with the Marlinyu Ghoorlie and maintaining a close and collaborative relationship with all stakeholders.” APPROVED FOR RELEASE This announcement has been authorised for release by the Managing Director.
