On 2 December 2025, Liontown Limited announced the completion of open pit mining at the Kathleen Valley Lithium Operation, delivered on schedule and marking the transition to fully underground operations. The final truckload of ore has departed the Kathleen’s Corner pit, concluding three years of open pit mining, with Kathleen Valley now operating as a fully underground lithium operation.
Below are the highlights:
- Open pit mining successfully completed on schedule, transitioning Kathleen Valley to a 100% underground mining operation.
- The open pit was critical in providing material for construction of the Run-of-Mine (ROM) pad and tailings storage facility, whilst providing the initial mill feed for startup commissioning and ramp up of the process plant.
- Planned strategic open pit ore stockpiles enhance operational flexibility and provide feed security through to early FY27, supporting the underground transition and ramp up.
- Underground operations are ramping up to plan, with development and production progressing as scheduled to prioritise high-margin ore.
