Cornish Lithium has announced a significant 50% increase in the JORC-compliant Mineral Resource at its Trelavour Lithium Project in Cornwall, following a year of extensive drilling, sampling, testing, and modelling.
The updated resource now stands at 88.5 million tonnes grading 0.21% Li₂O, equivalent to 183.5 thousand tonnes of contained lithium oxide. This equates to 454.5 thousand tonnes of lithium carbonate equivalent (LCE), representing a 50% increase compared to the 2022 estimate. Importantly, the upgrade includes a maiden declaration of resources in the Measured and Indicated categories, boosting geological confidence in the deposit.
CEO Jamie Airnes highlighted the importance of the milestone: “Today’s resource upgrade also provides a strong foundation for our Feasibility Study, which we expect to publish later this year, moving us closer to our Development Consent Order application and commercial production. This is one more step in Cornish Lithium’s plan to secure the UK’s critical minerals supply, jobs and industrial future.”
The project benefits from its location in a former china clay pit, with resources extending from the surface, resulting in a low strip ratio. To date, more than 20,000 metres of drilling have been completed, including exploration and geotechnical holes.
Cornish Lithium aims to produce 10,000 tonnes per year of battery-grade lithium hydroxide, with commercial production targeted for 2029. The project is designed as a fully integrated operation with proprietary low-carbon processing technology, ensuring independence from overseas refineries and alignment with the UK’s clean energy transition.
