Mining By Maxwell Dee 3 min read

Liontown Resources has successfully ramped up production at its Kathleen Valley Lithium Operation, marking a milestone as Australia’s first underground lithium mine begins ahead of schedule. The company reports strong operational and financial performance amid robust lithium demand.

  • Kathleen Valley lithium production commenced July 2024, ramp-up on track
  • Underground mining started April 2025, ahead of schedule
  • Positive net cash flow for two consecutive quarters
  • Record spodumene concentrate production and improving recovery rates
  • Strong lithium market demand despite price softness due to inventory destocking

Operational Milestone Achieved

Liontown Resources has reached a significant milestone with the successful ramp-up of its Kathleen Valley Lithium Operation, Australia’s newest lithium producer. Since first production in July 2024, the company has demonstrated strong operational execution, producing over 200,000 dry metric tonnes of spodumene concentrate by March 2025. This achievement underscores Liontown’s capability to deliver on schedule in a challenging market environment.

Notably, underground mining commenced in April 2025, ahead of the planned timeline, marking Kathleen Valley as Australia’s first underground lithium mine. This transition supports a multi-decade mine life, leveraging high-grade ore reserves and operational efficiencies from two major orebodies, Mount Mann and North-West Flats.

Financial and Operational Performance

Financially, Liontown has reported positive net cash flow from operating activities for two consecutive quarters, reflecting disciplined cost management and robust sales. The company achieved a record monthly production of 37,171 dry metric tonnes in March 2025, with an average realized price of US$812 per tonne (CIF). Processing efficiencies continue to improve, with lithia recovery rates climbing to 64% in the March quarter and a target of 70% recovery by Q3 FY26.

Operationally, the open pit mining at Kathleen’s Corner remains on track for completion by Q3 FY26, while underground development is progressing ahead of schedule, with over 9,200 cumulative development metres achieved. The underground operation benefits from finer rock fragmentation and improved ore hygiene, which are expected to enhance processing performance and reduce environmental footprint.

Market Context and Strategic Outlook

The lithium market continues to show strong demand growth driven by electric vehicle (EV) sales and energy storage systems, with major battery manufacturers like CATL forecasting significant increases in lithium consumption through 2030. However, lithium prices remain subdued due to inventory destocking and tariff uncertainties, masking the underlying strength of end-market demand.

Liontown’s strategic capital investments today aim to secure future growth and cost efficiencies, including infrastructure to support a potential 4 million tonnes per annum operation. The company also highlights downstream integration opportunities with strategic partners LG Energy Solutions and Sumitomo, positioning itself to capture additional value in the battery supply chain.

With a robust cash balance and a reputation for delivery, Liontown is well placed to capitalise on the anticipated market turnaround and sustain its position as a responsible provider of battery minerals.

Bottom Line?

Liontown’s early underground mining success and strong cash flow set the stage for sustained growth amid evolving lithium market dynamics.

Questions in the middle?

  • How will ongoing lithium price volatility impact Liontown’s production ramp-up and profitability?
  • What are the timelines and prospects for Liontown’s downstream integration partnerships?
  • How will the transition from open pit to full underground mining affect operational costs and environmental footprint?
