Hamilton Basin

South Australia

One of the largest untested uranium targets globally — a roll-front / palaeo-channel corridor ±180km × 50km in strike length. The basin architecture closely mirrors the uranium-producing Frome Embayment to the east and the world-class Kazakhstan in-situ recovery (ISR) districts.

South Australia · 1 EL · 273 sqkm

Algebuckina

South Australia · 1 EL Granted · 273 sqkm

Multiple uranium occurrences within the project area. Drill hole AG0714 immediately south returned 2m @ 213ppm U + 329ppm V in pyritic and organic-rich Cadna-Owie Formation sediments. Up to 3,320ppm U recorded in granites to the south — Rössing-style intrusive-hosted mineralisation (Rössing Mine: 80Mt @ 0.035% U₃O₈).

Radiometric Signature Map — 7km Anomaly

Algebuckina radiometric signature map — well-defined 7km U²/Th anomaly coinciding with unconformity sequence and basal Algebuckina Sandstone

Well-defined 7km radiometric anomaly coinciding with the unconformity sequence of basement rocks and the basal Algebuckina Sandstone — a highly prospective structural setting for uranium concentration. Base image: SARIG — map.sarig.sa.gov.au

Key Facts

Anomaly Size7km × well-defined U²/Th radiometric anomaly

Structural SettingUnconformity between basement rocks and basal Algebuckina Sandstone — classic uranium trap geometry

SignificanceCoincidence of radiometric anomaly with unconformity contact defines a high-priority drill target

Yalyirimbi

Northern Territory · 1 EL + 2 ELA · 324 sqkm

Three palaeo-channel targets identified within the project area. Existing drill holes within an incised Eocene-age palaeo-channel returned 4.5m @ 120ppm eU₃O₈, 1.5m @ 160ppm eU₃O₈, and 1.0m @ 110ppm eU₃O₈. Up to 0.17% U recorded in 'hot' basement rocks immediately north of the project — a potential uranium source feeding the palaeo-channel system. Additional REE (ionic-clay) potential identified.
