Further Uranium Mineralisation Intersected at Big Lake

Key points

• Thirty-three aircore holes completed with uranium mineralisation found at Site 10.
• Follow-up drilling at Site 10 confirms roll-front uranium exploration model.
• Uranium mineralisation also found 6km south of Site 10, suggesting broader potential.
• CEO highlights potential scale and regional exploration focus.

Full summary

Alligator Energy Ltd has announced further uranium mineralisation at its Big Lake Uranium Project in South Australia. The 2026 exploration drilling program completed 33 aircore holes for 4,112 metres, intersecting uranium mineralisation at Site 10. Key intersections include 1.0 metres at 0.018% eU3O8 and 1.9 metres at 0.032% eU3O8. Follow-up drilling at Site 10 has confirmed the interpreted redox boundary between oxidised and reduced sands, supporting Alligator's roll-front uranium exploration model. Regional drilling 6km south of Site 10 has also intersected similar oxidised and reduced sands at comparable depths, suggesting the favourable geological setting extends beyond the initial discovery area. Alligator's CEO, Dr Andrea Marsland-Smith, emphasized the potential scale and regional exploration focus, highlighting the project's early-stage exploration opportunity.

Outlook

Alligator Energy plans to continue drilling at Site 10 and in the surrounding area to better define the geometry and continuity of the interpreted redox front, with the program potentially extending into Q4 2026.
