Imerys British Lithium is a joint venture between Imerys (UK) Limited and Lithium Assets Limited (formerly British Lithium Limited) – a rapidly growing and agile lithium resource development company based in Cornwall. We possess patented technology for the sustainable recovery of battery-grade lithium carbonate from micaceous granite.
Currently, we are conducting an extensive pre-feasibility study to develop the world’s first integrated lithium mine, beneficiation plant, and refinery. The project aims to produce 20,000 tpa of lithium carbonate, supporting the annual production of 350,000 electric vehicles in the UK.
Located on land leased long-term from Imerys (UK) Limited, the project encompasses former China Clay quarries, Gunheath, and Goonbarrow, which have a rich history of China Clay mining spanning over 275 years.
We have already established a JORC compliant Inferred Mineral Resource of 160.8 Mt at 0.537% lithium oxide within a micaceous granite. As part of the Pre Feasibility Study, extensive drilling activities, including diamond and reverse circulation drilling, are underway to improve and upgrade the mineral resource estimate. All samples are assessed and processed at the on-site exploration camp.
To support the processing development, we operate a state-of-the-art pilot plant, where we are developing unique LiMica-Sep™ and Li-Sep™ technologies for sustainable lithium extraction from micaceous granite. The facility utilises various process technologies, including mineral beneficiation, pyrometallurgy, hydrometallurgy, precipitation, crystallisation, and ion exchange, at both laboratory and industrial scales.
