Critical Raw Material (CRM) prospectivity in the UK was undertaken by the British Geological Survey (BGS) in 2023.
The report notes that areas in north-west Wales and Pembrokeshire are prospective for several CRMs and are a priority for further geological investigations.
It is my understanding that the UK Government will publish a new Critical Minerals Strategy this year.
