A team of data scientists at the Satellite Applications Catapult is leading a new study to see if it is possible to detect a lithium ‘fingerprint’ from space by imaging vegetation and minerals on the ground using satellites.
The data from the study will be integrated with geological information to create a ‘prospectivity map’ to help identify indicators of geological structures which may host lithium in waters (known as brines) deep below the surface.
The study, funded by Innovate UK, is taking place in Cornwall where there are many historical accounts of brine containing lithium, some dating back to as early as 1864. Now that lithium has become a crucial material for the development of electric car batteries, the lithium in Cornwall may represent an important resource.
Lithium consumption is expected to grow rapidly over the next few decades as electric vehicles become mainstream. Additional demand is expected to come from power storage batteries that will be used to store electrical power harvested from renewable sources such as wind and solar.
The challenge posed by the study is to understand whether satellite techniques can assist in prioritising areas for exploration for the future production of lithium.
Cornish Lithium Ltd is leading the search for lithium in Cornwall and the results from this project are expected to expand the company’s understanding of the geological structures which are the main targets for where lithium may be extracted from in the future.
Founder and CEO, Jeremy Wrathall, said: “We are delighted to be part of this exciting project, as well as for the recognition that our project has received from Innovate UK.
“Lithium has significant strategic importance to the UK economy and we hope that the funding will accelerate understanding of the potential to extract lithium in Cornwall. We believe that techniques developed from this study will prove of great interest to the mining industry globally given the growing importance of Earth Observation techniques as an unobtrusive exploration tool worldwide.
“We look forward to taking this exciting project forward to the next stage of its development.”
Dr Cristian Rossi, principal EO specialist at Satellite Applications Catapult, added: “Project Lithium is a very exciting project for the Catapult. We get to push boundaries by integrating cutting edge Earth Observation techniques with local surveys to develop the first digital maps that display the probability of occurrence of lithium in Cornwall. Initial investigations show promising outcomes and the team is currently working on their validation.”
The project is due to have results by the end of March.
