Cornish Lithium, the mining start-up looking to commercialise battery metal deposits in the southwest of England, says its latest test borehole represents a breakthrough for the company due to the concentration of lithium found.

The Twelveheads borehole, the company's third in the area, was sunk to a depth of 1,974m where it found brines with an average lithium content of about 100 parts per million (ppm), Cornish Lithium says. The temperature at the final depth was 72C, a potential source of carbon-free heat that it could sell to local businesses.
