2025 drilling campaign completed at Overland Uranium Project

Highlights:

• Overland Drilling Completed: A total of 45 drill holes for 5,090 metres has been completed under the 2025 Overland drilling program - marking the second phase of AR3’s drilling for the year (see ASX release 28 July 2025). Since October 2024, AR3 has completed 16,316m of drilling across 152 holes confirming consistent geological continuity and expanding the project’s uranium footprint.

• ISR Uranium Target Identified: Recent assay, gamma, and pXRF results confirm the presence of a permeable sand unit located beneath a clay and lignite horizon at the base of oxidation. This defines a compelling ISR-amenable uranium target in the north-western region of EL7001.

• Strong Uranium Intercepts: Assays received to date validate down-hole gamma and in-field pXRF readings for contained uranium, including:

• OV100 2m at 87ppm U3O8 from 69m

• OV105 1m at 213ppm U3O8 from 73m

• OV125 1m at 116ppm U3O8 from 67m

• OV128 1m at 163ppm U3O8 from 77m

• OV130 2m at 126ppm U3O8 from 70m

• Follow-up Drilling Confirms ISR Potential: Infill drilling centred around OV105 and OV128 has defined a permeable sand horizon returning elevated uranium values within sand and lignite units, strengthening confidence in the continuity of ISR-amenable mineralisation (refer Figures 3, 4 & 5).

• Extensive First-Pass Drilling Coverage: Systematic drilling across AR3’s 7,700 km² tenure has now evaluated multiple target areas, with the highest uranium grades concentrated in the north-western corner of EL7001.

• Program Review:AR3’s 2025 drilling program at Overland is now complete and geology and assay data is being reviewed for follow up targeting and testing as part of planning for a 2026 drilling program.
