Roche-based British Lithium Limited (BLL) has been awarded £500k of match grant funding from the Government to progress its research and development of hard rock lithium extraction in the St Austell area of Cornwall.

With an application success rate of around 6%, the Innovate UK Smart Grant is a highly sought-after award and winning it is testament to the strength of BLL’s business case.

This week’s announcement follows the company’s recent declaration of an official JORC (Joint Ore Reserves Committee) resource target and a successful preliminary economic assessment (PEA) – a scoping study that analyses the technical feasibility and economic viability of a proposed mining project.

BLL is the first company in the UK to explore for hard rock lithium and the only one so far to have established a resource.

“We have undertaken many years of metallurgical research to develop a unique process for extracting lithium from micaceous granite – something never done commercially before,” said BLL’s chairman Roderick Smith. “We have our own laboratory in Roche and our aim is to build a quarry and refinery in Cornwall that will produce 20,000 tonnes per year of lithium carbonate.”

Lithium is a highly reactive and relatively light metal that is ideal for use in batteries – including those that power electric cars. Whilst 2020 has seen a dramatic decrease in the number of petrol and diesel cars sold, sales of zero emission vehicles increased by nearly 160%. Cars represent the UK’s largest export by value and car manufacturers co-locate with battery makers. A number of large lithium-ion battery plants are already under construction in Europe but only one such gigafactory is currently proposed for the UK.

“The amount of lithium we are planning to produce annually will be a major step forward in attracting more battery manufacturers and maintaining our car industry,” said BLL MD Andrew Smith. “If batteries aren’t being made in the UK, car makers are likely to continue investing in EV production in Europe because that’s where the gigafactories are. Yet Europe isn’t actually producing any battery-grade lithium so achieving that in Cornwall would give the UK as a whole huge competitive advantage.”

BLL carried out its first drilling programme in April 2019 after years of research and reconnaissance. Further trenching took place five months later, followed by an intensive 24-hour diamond-core drilling programme in December. An on-site team of six is now preparing for a third phase of exploration.
