Cornish Lithium — which wants the government to set a target for domestic production of 50,000 tonnes per year — hopes to jump-start UK production by extracting lithium from granite and from the underground brines that run between cracks in the rocks in Cornwall.
The company, which reported an £8.6mn loss last year, is aiming to produce 25,000 tonnes a year by 2030, enough to supply more than 500,000 electric cars.
But lithium prices have crashed by more than 50 per cent in the past 12 months and are currently around half the $20,000 level that Cornish Lithium said was needed to create the incentive to develop new supplies. The company expects its granite mining project to be profitable below that level, but did not disclose at what price.
Imerys British Lithium, a joint venture between the French multinational and the UK start-up, plans to produce 21,000 tonnes of lithium per year by 2030 in a neighbouring Cornish mining project that is expected to cost around £575mn.
Cornish Lithium’s demonstration plant will produce samples of lithium hydroxide for customers such as carmakers, and the company is finalising a study that will outline the cost of scaling up its granite mining operation.
Chief financial officer Varshan Gokool said costs would be higher than the $243.8mn in capital expenditure estimated in 2022, partly due to inflation.
US-government backed investor TechMet, the UK’s National Wealth Fund and private investor the Energy & Minerals Group ploughed a combined $67mn into Cornish Lithium last year, which they said could be followed by a second round of up to $210mn.
Brian Menell, CEO of TechMet, said the project’s lithium would not “be at the bottom of the global cost curve but it won’t be at the top either”.
Getting the lithium out is only the start of a complex supply chain, with experts stressing the need for the UK to invest in mineral processing and recycling to grow a domestic industry.
While much mining occurs in Australia and South America, “you need to worry about the refining and the battery manufacture” to reduce dependence on China, said Colin Church, CEO of the Institute of Materials, Minerals & Mining.
Many lithium miners ship their material to processors in China, where it is converted into lithium hydroxide or carbonate that is then bought by carmakers.
“Digging it out of the ground and shipping it somewhere else isn’t increasing your security of supply,” said Jeff Townsend, founder of the Critical Minerals Association.
Cornish Lithium plans to produce lithium hydroxide, in what it says would be a first in the UK. The Imerys joint venture also plans to process on site and sell lithium carbonate. Meanwhile, Tees Valley Lithium and Green Lithium are aiming to build refineries in the UK.
