Liontown Resources Begins Underground Lithium Production at Kathleen Valley

Liontown Resources Limited (ASX: LTR) has achieved a significant milestone by commencing underground lithium production at its Kathleen Valley Lithium Operation's Mt Mann orebody in Western Australia, marking Australia's first underground lithium mining operation.

Key Highlights:

• First underground production stope successfully fired, extracting approximately 1,500 tonnes of ore.

• The initial stope is designed to extract about 12,000 tonnes, roughly equivalent to two days of plant production.

• Recent trials confirmed excellent processability of the underground ore with grades around 1.5% Li2O and lithium recoveries exceeding 70%.

• Underground mining is expected to provide cleaner ore extraction, lower ore dilution, higher recoveries, and improved ore fragmentation for optimized processing.

• Progressive ramp-up planned with the mill expected to rely solely on underground and stockpiled ore by Q4 FY26.

Managing Director and CEO Tony Ottaviano stated, "This milestone is a proud achievement for Liontown, enabled by extensive planning and the dedication of our team and mining partner, Byrnecut. The successful trials reinforce our confidence in transitioning smoothly to full underground operations, underpinning our long-term value creation strategy."

Further underground development and optimisation initiatives will continue as Liontown advances towards full-scale underground operations.
