Announcement PDF ASX Announcement 8 October 2025 Highlights: • Mobilisation of Field Recovery Trial (FRT) construction contractors has commenced, in line with schedule. • First results from the FRT expected through February to April 2026. • The FRT will generate critical operating data to support feasibility studies and de-risk future development of Samphire. • Definitive feasibility study and commencement of mining lease approvals to run in parallel to the FRT. Alligator Energy (ASX: AGE, ‘Alligator’ or ‘the Company’) is pleased to advise that Ahrens Group has commenced on-site construction for the Samphire Project FRT, near Whyalla, South Australia. The Ahrens team includes local Whyalla based contractors, who are now undertaking the civil works in preparation for plant construction. In addition to this, 75% of the well patterns have been drilled by Watson Drilling and is ahead of schedule. Alligator’s CEO Andrea Marsland-Smith stated: “The commencement of construction for the Field Recovery Trial is a pivotal step in bringing the Samphire Uranium Project closer to development and future production. The trial will provide essential operating and technical data, which will be incorporated directly into the Definitive Feasibility Study (DFS) that is currently underway. Importantly, this work is being undertaken in parallel with other critical project streams, including mining lease approvals and our operational readiness planning. Together, these activities demonstrate that Alligator is progressing Samphire at full pace, with a clear line of sight towards a development decision. Our team is focused on ensuring that when the trial results are received, we are in a strong position to transition seamlessly into feasibility completion and project execution. This progress comes at a time of strengthening global uranium markets, with rising demand driven by new nuclear power projects and the push for clean, reliable energy supply. Alligator is well placed to capitalise on this momentum, and our work at Samphire demonstrates the Company’s commitment to delivering one of Australia’s next uranium operations. We look forward to keeping shareholders updated of the progress and results of the FRT in the coming months, as we advance towards production.” Contractor for Samphire Field Recovery Trial Mobilised On Schedule 2 Figure 1 – Layout of the FRT production wellfields and pilot plant site.
