SnapshotThe Trelavour hard rock lithium project has been designated as a Nationally Significant Infrastructure Project by the UK Government due to its scale and potential economic impact.

In 2022, a Scoping Study was completed. The full text of the Trelavour Project Scoping Study report is currently not publicly available. However, key findings have been published on Cornish Lithium's official website.

According to the Scoping Study, Lithium will be extracted from Trelavour ore utilising concentration to a lithium mica concentrate followed by lithium extraction using the licensed Lepidico leaching process at an industrial site located in close proximity to the mine.

In October 2024, Cornish Lithium commissioned the UK's first low-emission lithium hydroxide demonstration plant at the project, which will provide operational data for the feasibility study. The feasibility study is expected to be published in early 2025.

Summary:

Cornwall is underlain by a mass of granite – the Cornubian batholith. This granite is one of five large scale bulk lithium-enriched granites worldwide (as mapped and highlighted by the USGS).

In Cornwall, lithium is contained within mica minerals (zinnwldite and lepidolite). Some Cornish granite is more highly enriched in lithium than others.
