Announcement PDF ASX Announcement 4 November 2025 Highlights: • In-situ recovery (ISR) pilot plant successfully delivered to the Samphire Project site, near Whyalla. • Mechanical, electrical, and pipework installation for field trial commenced. • Drilling of recovery well patterns for areas A and B now complete. • Civil works remain on schedule and progressing well. Alligator Energy (ASX: AGE, ‘Alligator’ or ‘the Company’) is pleased to advise that following earthmoving works and bund installation, the pilot plant for the Samphire Uranium Project Field Recovery Trial (FRT) has now been delivered to site and that mechanical, electrical and pipework installation has commenced. The delivery of the pilot plant marks another significant milestone for the Samphire Project, bringing Alligator closer to the commencement of the FRT. In addition to the pilot plant, drilling of the recovery well patterns for areas A and B are now complete, with the site civil works advancing in line with schedule. Alligator’s CEO Andrea Marsland-Smith stated: “The arrival of the pilot plant and completion of the recovery well patterns mark another strong milestone for the Samphire Project. With mechanical, electrical, and pipework installation now underway, we are approaching the final phases of construction ahead of commissioning of the plant. These achievements reflect the excellent collaboration between our team and our construction contractor Ahrens, who has delivered each milestone on schedule. Importantly, this work continues to advance alongside the Definitive Feasibility Study, commencement of mining lease approvals and trial operational readiness planning – ensuring that when the FRT results are received, we will be in a position to move seamlessly into the next phase. Alligator is now one of only a handful of uranium developers with a project advancing toward near term production in Australia. The Samphire Project provides a unique opportunity to deliver a low cost, low impact ISR uranium operation in a Tier 1 jurisdiction, at a time when global demand for reliable, clean baseload energy continues to accelerate. Our focus remains on maintaining momentum through this phase.
