Mining in Cornwall and Devon, in the southwest of Britain, is thought to have begun in the early-middle Bronze Age with the exploitation of cassiterite. Tin, and later copper, were the most commonly extracted metals. Some tin mining continued long after the mining of other metals had become unprofitable, but ended in the late 20th century. In 2021, it was announced that a new mine was extracting battery-grade lithium carbonate, more than 20 years after the closure of the last South Crofty tin mine in Cornwall in 1998.
