Mineral Resources Mapping of Orthomagmatic Deposits in Europe
This map viewer presents the results of the resource mapping of orthomagmatic mineral deposits in Europe. This task was part of the Work Package 5 of the SEMACRET project. Data were systematically collected, reviewed, complemented and evaluated between November 2023 and February 2025. As the source of information were used existing national and EU databases as were as other additional literature (articles, press releases, reports, etc.). It covers EU and associated European countries (Norway, South Balkan countries) as well Greenland, associated with the EU thorough Denmark as overseas territory which recently signed strategic partnership on sustainable raw materials value chains with the EU.
The map shows different types of mineralizations associated with orthomagmatic mafic-ultramafic mineral systems:
The database that has been created to this purpose contains basic information, localization with coordinates, characterization of occurrence type, resource quantities (if available), including UNFC1. In addition to the basic information, for majority of points is available a link to passport with more detailed information.
The map viewer allows to filter data by different attributes, such as occurrence type (deposit, prospect, occurrence), mine status (operating, under development, not operating) or importance (very large, large, medium, small) which are based on INSPIRE Mineral Resources Theme definitions2 . Other filter options are by mineralization type or by classification method applied for the resource estimate.
To learn more about the specific definitions applied in the map viewer and the passports see the Terminology.

Disclaimer:
Information provided in the Map viewer and respective Mineral deposit passports are based on the literature review at the time of data collection. The purpose of the Map viewer is to illustrate general mineral potential of selected deposit type in the EU and associated countries. It is not aimed to be neither an inventory nor any kind of qualified assessment, advice or official statement. Authors are not responsible for the use which might be made of this application. It is recommended to verify an up to date information of respective objects from reliable sources.
1 - For the UNFC, the United Nations Framework Classification Update 2019 and related guidances
and documents has been applied. For further information see: https://unece.org/sustainable-energy/publications/united-nations-framework-classification-resources-update-2019-ece.
For
CRIRSCO-compliant resource estimates, respective UNFC class is not displayed
Occurrence ID – unique identifier of each mineral occurrence in the database
Occurrence name – name or names under which the occurrence or deposit is known/registered in other databases or literature
Country – name of the country, where the occurrence is placed
Occurrence type – based on INSPIRE Mineral Occurrence Type 2 with corresponding definitions of occurrence, prospect and mineral deposit in relation to the level of knowledge and economic potential
Mineralization type – usual association of valuable elements (metals) in this type of mineralization (mentioned elements are not necessarilly present in this occurrence)
Importance – Importance of the deposit based on INSPIRE Importance Value (European Commission, 2024). Express the classification of deposit size of the deposit according to the commodity quantity. Class boundaries are based on a statistical study of a large set of deposits throughout the world and defines what is a very large, a large, a medium-sized etc. deposit for this commodity.
Classification method – classification method applied in the most recent resource estimate CRIRSCO-compliant – resource estimate applies classification in line with CRIRSCO - family reporting standard. The current holder is the one who has issued or confirmed the estimate, thus it is considered CRIRSCO-compliant. Historic CRIRSCO – resources have been classified according to the CRIRSCO-family standard, however, the company has left the tenement or there has been an ownership change without amending the resource estimate. Such estimates are usually referred as historic or foreign and are not considered CRIRSCO-compliant sensu stricto. Non-compliant/historic – the resource estimate is not in line with any CRIRSCO-family reporting standard and related classification. The classification might be in line with some national standard, or it is a historic/not standardized classification No resource estimate – the resource estimate does not exist (is not known).
Estimation date – date of the issue of the estimate. In the case of CRIRSCO-compliant estimates, the Effective date is provided. In the case that only year is known, the date 31.12. + year is used.
Total ore (t) – total tonnage of all resource and reserves categories, based on the most recent available estimate (the last estimate for which the tonnages and grades has been available, based on the literature).
Best UNFC class - the UNFC class that best represents the Project development status and overall confidence in the resource estimate. For CRIRSCO-compliant resource estimates, the UNFC class is not displayed.
Best UNFC amount – Proportion of commodity quantities, that corresponds to the Best UNFC class.
Additional UNFC class + Additional quantities - The project itself may contain additional commodity quantities with different UNFC classes.
INSPIRE Mine Status – status of the mine development based on INSPIRE Mine Status 3 with corresponding definitions of operating, under development, not operating
