Geology and Resources

Wiluna consists of six deposits, the approved deposits of Centipede and Lake Way, and the Millipede, Lake Maitland, Dawson-Hinkler and Nowthanna deposits.

The Centipede and Lake Way deposits are carbonate associated surficial uranium deposits. This means the uranium is found close to the surface and is often associated with naturally occurring magnesium and calcium carbonate minerals known as Dolomite and Calcite. The uranium itself is contained within a mineral called Carnotite, which also contains potassium and vanadium and which also precipitates naturally near the top of the water table. The entire deposit to be mined at Wiluna is no more than 12 m deep.

This type of deposit is not unlike the nearby larger Yeelirrie deposit, owned by Cameco Corporation, and the Langer Heinrich deposit in Namibia being mined by Paladin Energy.

The Wiluna resource currently planned to be mined is 96.5% measured and indicated according to the JORC 2012 code, and 3.5% inferred.
