Abstract

Historic records have shown that lithium enriched geothermal waters circulate within natural geological fractures at depth in Cornwall. These fracture zones outcrop at surface and can be examined to understand which structures are most prospective for further exploration. Using airborne hyperspectral imagery, a rapid and high-resolution survey of alteration patterns can indicate the structures that have interacted with geothermal water. Spectra were analysed for kaolin and haematite minerals which were successfully identified and subsequently verified using lab analyses. A drilling campaign was successful in confirming the presence of lithium in structures that were identified in the remote sensing programme.
