While the broader term ‘mineral resources’ encompasses a wide range of geological materials, this dataset focuses solely on metallic minerals. These are defined in accordance with international mineral resource standards to include both geological characteristics and potential economic considerations. The dataset is based primarily on mapped geology, with limited assessment of economic viability, and is intended to show the distribution and extent of metallic mineral occurrences rather than potential extraction areas or mineral reserves. The Welsh Assembly Government recognised the importance of managing mineral resources at a national level to maintain an appropriate balance between mineral supply and demand. In response, the British Geological Survey (BGS) was commissioned in 2009 (contract 252/2009/09) to provide a comprehensive and accessible information base to support sustainable mineral resource management across the 25 Unitary and Mineral Planning Authorities of Wales. This work formed part of the National Minerals Map of Wales and Aggregate Safeguarding Map of Wales, funded through the Welsh Aggregate Levy Sustainability Fund and co-funded by the BGS Sustainable Mineral Solutions project. This metallic minerals dataset is a thematic subset of the wider Welsh mineral resources dataset and was derived using the same methodology. Data production was completed in 2010, with minor revisions to geometry and attributes undertaken in 2020. The dataset enables users to visualise broad patterns in the distribution of metallic mineral occurrences across Wales and to consider their spatial relationship with other land-use designations, infrastructure, environmental constraints and conservation data. It is suitable for regional-scale planning and safeguarding assessments but does not indicate economically viable reserves, designate extraction areas, or confer planning status. Only onshore mainland occurrences are included. The data quality varies spatially and reflects the availability and resolution of underlying geological mapping. The presence of a metallic mineral occurrence does not imply current working, planning permission, or economic viability. Point data for metallic mineral occurrences have historically been included within related resource mapping; however, occurrence-level information is more comprehensively represented in other BGS datasets, such as the BGS BritPits database of mines and quarries. This dataset should therefore be used as a regional-scale spatial planning and safeguarding tool rather than as a definitive inventory of all recorded metallic mineral sites in Wales.

Important mineral occurrences were selected using expert judgment and existing literature on the location of mines and mineralised areas 2. Draft maps were shared with stakeholders for comment. 3. Approved maps were collated and prepared in GIS for dataset creation. 4. Data for metallic mineral commodities were merged into a regional file.
