Astral Resources NL (ASX: AAR) (Astral or the Company) is pleased to announce that its wholly- owned subsidiary, Feysville Gold Pty Ltd, (Feysville) has executed a Land Use Agreement with the Marlinyu Ghoorlie Native Title Claim Group (Marlinyu Ghoorlie). The Agreement covers tenements M26/846 and L26/295, which encompass the Think Big deposit within the Company’s 100%-owned Feysville Gold Project near Kalgoorlie. Astral Resources recently signed a Letter of Intent (LOI) with specialist mining services provider, Mineral Mining Services Pty Ltd (MMS), to form a Development Partnership/Joint Venture (JV) to develop the Think Big deposit as an early production opportunity (see ASX Announcement 20 October 2025). 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 Feysville’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 Feysville’s activities; and 2 astralresources.com.au ASX: AAR | • 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 Feysville. It paves the way for the grant of a Mining Lease and provides a strong foundation for Astral to progress the responsible development of the Think Big deposit under the proposed JV agreement with MMS. Under the LOI signed with MMS, Astral and MMS will pursue a standalone development at Think Big, with MMS to fund 100% of the development costs, which will be recovered from initial project cash flows. The proposed Think Big development provides an opportunity to deliver early gold production and cash-flow from Astral’s asset portfolio, providing funding to support the development of the Company’s flagship Mandilla Gold Project, potentially reducing the debt and equity funding requirement and minimising shareholder dilution. The Think Big deposit hosts a Mineral Resource Estimate of 2.4Mt grading 1.1g/t Au for 85,200 ounces of contained gold1 . Within the Mandilla Pre-Feasibility Study, Think Big was forecast to contribute approximately 30,000 ounces of gold production to the life-of-mine plan, with first production scheduled to commence in year three. Under the agreement with MMS, these ounces from Think Big will now be brought forward to the start of the mine plan. Astral Resources’ Managing Director Marc Ducler said: “We are delighted to announce the execution of this Land Use Agreement, which marks another step forward in our collaborative and positive relationship with Marlinyu Ghoorlie. This Agreement provides a clear and cooperative framework, safeguarding Aboriginal Cultural Heritage and laying the foundations for Marlinyu Ghoorlie’s participation in the development of the Think Big Project. “This agreement underscores Astral’s strong commitment to maintaining a close and collaborative relationship with our stakeholders and provides a strong platform for us to now execute definitive, binding agreements for the Think Big Development JV.” APPROVED FOR RELEASE This announcement has been authorised for release by the Managing Director.
