5 kilometres west of the former Jabiluka mine. The ore is found at the contact between the Cahill Formation and the Nanamba Complex, and covered in 30 metres of alluvium and sand. Mineralisation is present in chloritised breccia, pegmatoid, and lesser quartz-sericite-chlorite schist of the lower Cahill Formation, and occurring less than 200 metres to the contact with the Nanamba Complex.

Sooty and colloform uraninite mineralisation is immediately below the Cretaceous unconformity. Copper mineralisation is present as sooty chalcocite within the uranium deposit.

Drilled in 1978 by Peko-Wallsend and Electrolytic Zinc Company of Australasia Limited. The mineralisation covers 200 metres but is poorly defined. Estimated 1.5 MT averaging 0.357% U3O8.
