Geothermal
production facility
Following positive exploration results from work at Cross Lanes near Redruth, the waters that flow deep beneath the surface of the area have been identified as having potential for commercial lithium extraction. As a result, we are now planning a pre-commercial project in the area. This will include the construction and operation of a geothermal lithium production facility and the development of two additional 2,000-metre-deep boreholes.
Frequently asked questions
The Cross Lanes area (previously known as Twelveheads) was selected as a promising site to explore for lithium in geothermal waters following intensive desk studies, 3D modelling, and reviewing historic mining data for the area
Exploration drilling took place in 2022 and 2023, with further testing of the waters throughout 2023 and 2024. After positive exploration results, a decision was made to progress this to a pre-commercial lithium production facility.
A full planning submission for a pre-commercial lithium production facility at this site is currently in determination, and if approved work will begin as outlined in the planning documents for the lithium production facility and associated infrastructure.
The final depth of the borehole was around 2km, with a lithium grade of 100ppm, and a final borehole temperature of 70 degrees.
The Mineral Planning Authority at Cornwall Council provided temporary permission for exploration work, under the submission number PA22/00830 and permission was sought from the Environment Agency. Full planning for the pre-commercial site is currently being considered under PA24/06661.
As part of our ongoing commitment to proactive community engagement, we have held several community information sessions to date.
Our team presented the plans, updates, and discussed any questions regarding the planning application before its submission. This event gave local residents the opportunity to learn about the potential for the environmentally-responsible extraction of lithium from the waters that run deep beneath the surface of Cross Lanes, following the positive test results from Cornish Lithium’s recent exploration borehole at this site.
Further sessions will be held as the planning and project progresses.
The site is being designed with environmental considerations. An Ecological Impact Assessment (EcIA) for a commercial plant at this location has been commissioned, which outlines potential impacts and mitigations. The full document is available as part of the planning application PA24/06661.
