The GeoERA project Mintell4EU builds on existing data sets developed by projects such as ProMine, EuroGeoSource, Minerals4EU, ProSum, euRare, MICA and EGDI. It aims to update the European minerals yearbook with production and trade data, resource and reserve data as well as exploration information, and to improve the quality and spatial coverage of the minerals inventory, addressing harmonization issues and facilitating interoperability with other ongoing European mineral intelligence projects. Furthermore, it will test the application of the UNFC classifications to obtain more accurate pan‐European mineral inventories, and recommend communication and interaction between existing databases and data portals, and the Raw Materials Information System (RMIS). It will integrate the yearbook and minerals inventory into the GeoERA Information Platform (GIP), provide user-oriented search and visualisation facilities and enable interoperability of raw materials data with data on groundwater and geoenergy resources to support spatial planning and management of competing land uses.
