Cornish Lithium lead geologist Lucy Crane walks through a forest towards an old processing plant at United Downs. An area once dominated by copper and tin mines, the location – in Gwenapp, Cornwall – is the site of exploratory drilling for lithium, and also the Deep Geothermal Power Project, which aims to use heat from the earth as a domestic power source.
Whilst some of the borehole drilling speculating for lithium is on the spoil of old mines, much of it is small scale and incongruous, taking place at United Downs, on an industrial estate. The area was identified as a site to test for lithium-rich geothermal waters. The containers in the left of this image contain samples awaiting shipment to Vancouver for testing.
