Name of the Project                                    
Kathleen Valley lithium/tantalum project.

Location
North-east Goldfields of Western Australia.

Project Owner/s
Lithium developer Liontown Resources and Hancock Prospecting.

Project Description
A definitive feasibility study (DFS) has confirmed the potential to develop a state-of-the-art, second-generation lithium/tantalum mining and processing operation.

The DFS optimises the mine schedule, process plant design and forecast sales pricing to enhance the technical and financial viability of a standalone, long-life, four-million-tonne-a-year operation.

The project has an ore reserve of 68.5-million tonnes grading 1.34% lithium oxide and 120 parts per million tantalum pentoxide, underpinning an initial estimated 23-year mine life, based on the updated mining schedule.

Building on the October 2020 prefeasibility study, the DFS base production has been increased from two-million tonnes a year to 2.5-million tonnes a year, producing about 500 000 t/y of spodumene concentrate, with a four-million-tonne-a-year expansion planned in Year 6 to deliver about 700 000 t/y spodumene concentrate.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The project has an after-tax net present value, at a real 8% discount rate, of A$4.2-billion and an internal rate of return of 57%, with a payback of 2.3 years.

Capital Expenditure
Capital costs for the project are now estimated at A$951-million, up from the previous estimate of A$895-million.

Planned Start/End Date
Kathleen Valley achieved first production in July 2024 and successfully loaded and dispatched its inaugural shipment of spodumene concentrate in September 2024.

Latest Developments
Liontown Resources dispatched its first cargo of spodumene concentrate, totalling about 33 000 wet metric tons (wmt), from the Port of Geraldton on December 11. 

The cargo, Liontown's largest to date, includes 11 000 wmt designated for LG Energy Solution, with the remainder sold to a short-term customer. The shipment's concentrate has a weighted average grade of 5.2% lithium oxide.

This marks Liontown's fourth shipment since production started at the project and the first delivery under its long-term supply partnership with LG Energy Solution.

The Kathleen Valley operations remain on track as Liontown continues to scale up production and establish its position as a key supplier in the lithium-ion battery market.
