The project is located on the western edge of the Norseman-Wiluna Greenstone Belt, about 60 kilometres north of Leinster, and 680 kilometres north-east of Perth, Western Australia.
Kathleen Valley is one of the world’s largest and highest-grade hard rock lithium deposits and, with an initial 2.5 Mtpa production capacity, it is expected to supply ~500,000 tonnes of 6% lithium oxide concentrate per year. With first production expected in Q2 2024, the deposit will also produce Tantalum Pentoxide, a valuable material used in electronics and optics manufacturing.
Mining will predominately be underground, allowing direct access to higher grade mineralisation while minimising waste and the environmental footprint of the project, with mined ore processed through a Whole of Ore Flotation circuit.
