Under the Act of June 9, 2011, Geological and Mining Law (Journal of Laws No. 163, item 981, as amended) Polish Geological Institute – National Research Institute (PIG-PIB) performs the role of Polish Geological Survey. One of the tasks of PIG-PIB as Geological Survey is to create and maintain geological databases, in this including the system MIDAS (the System of management and protection of mineral resources in Poland – MIDAS). System MIDAS is the primary source of information on mineral resources of Poland, the exploitation of deposits and it is the source of data for the project Mintell4eu. The System contains information on deposits (and its spatial location), raw materials in deposits, raw materials resources and on the raw materials volumes of exploitation. In addition, it also contains data on mining areas and exploatation permits (concessions) as well as their spatial location. The owner of the colected data is the State Treasury represented by the proper minister resposible for geology. The original MIDAS database structure has been modified and adapted to the structure given in Mintell4eu specification.

Since the end of the 1980ies the geological, areal and production data of operating mining sites have been collected systematically by LGRB. The periodic update of this information is carried out every four or five years. Main reasons are 1) the preparation of the periodic follow-up of the 12 regional development plans, 2) the work on the near-surface mineral raw material maps published by LGRB, and 3) the periodical editing of the state report for near-surface mineral raw materials published by LGRB at the start of each new election period. The geological data include a detailed documentation of the thickness, petrography and quality of mined rock(s) and the overburden as well as geochemical data gained from rock samples. The areal data refer both to the permitted mining area (zones of recultivation, work and expansion) and to possible areas for the mine expansion (the latter are confidential). Due to the quick spatiotemporal variability of these data, here all mining sites are shown as point data. The confidential annual production data are the basis for the periodic raw material report. In addition, another data are collected, e.g. for the mining permission, the delivery area and the subsequent land use. All these data are stored in the mining site database of the LGRB (Rohstoffgewinnungs-stellendatenbank = RGDB). This one comprises also the data for abandoned mining sites and mines. In total, actual (2021) about 14.000 data records are stored. The name of each mining site (e.g. RG 6826-3) consists of three parts. RG is the abbreviation for "Rohstoffgewinnungsstelle". the following four-digit number means the number of the relevant topographic map 1 : 25.000. The last number means the serial number of the mining site; serial numbers 1-99 mark operating mining sites gathered since the end of the 1980ies ( (today partially already closed) , such > 100 mark abandoned mining sites collected before 1980 and such > 300 mark data of mining sites and mines collected in the course of actual raw material mapping.
The mintell4eu data set comprises all mining sites with serial numbers 1-99. In addition, the most important abandoned mines of former or probably still ongoing economic importance.

To provide public access to geological publications, maps, reports, databases, and research products that support geoscience research, natural resource management, and environmental decision-making in Arizona.

The Arizona Geological Survey (AZGS) serves as Arizona's primary source of geologic information and has been publishing geological maps, reports, and related materials since 1915. The Publications Repository acts as a centralized portal for accessing historical and current geological information produced by AZGS and its predecessor organizations.

The repository contains thousands of geological resources, including geologic maps, technical reports, bulletins, circulars, open-file reports, contributed reports, mining records, geochemical datasets, bibliographic records, oil and gas well data, geothermal data, subsurface resource information, and natural hazards datasets. Resources cover topics such as geology, hydrogeology, groundwater resources, mineral resources, mining, oil and gas, geothermal energy, geologic hazards, earthquakes, faults, earth fissures, flood risk, geochemistry, stratigraphy, paleontology, landforms, and environmental geology. The repository includes publications dating from 1915 to the present, as well as historical records from predecessor agencies. Users can access reports, maps, databases, interactive tools, and downloadable datasets through a searchable platform.

The repository aggregates publications, maps, and datasets produced through geological field investigations, geologic mapping programs, groundwater studies, mineral resource assessments, geochemical analyses, mining surveys, hazard investigations, oil and gas monitoring programs, and academic research conducted by AZGS and collaborating organizations. The platform serves as a digital archive and distribution system for these materials.

This U.S. Geological Survey (USGS) data release provides the descriptions of 10 U.S. sites that include mineral regions, mineral occurrences, and mine features that contain enrichments of graphite. To be included in this data release, sites must have a contained resource and (or) past production of more than 1,000 metric tons of graphite, which is approximately 3 percent of the average annual U.S. consumption of graphite from 2016 through 2020. Sites in this dataset occur in Alaska, Alabama, Colorado, Montana, New York, Pennsylvania, and Texas. There are known graphite occurrences in California, Connecticut, Georgia, Michigan, New Hampshire, New Jersey, North Carolina, Rhode Island, and Wyoming that have not been included in this database because contained resource and (or) production of graphite were not found above our cutoff in the public domain for these areas. Graphite is considered a critical and strategic mineral because of its essential applications in the aerospace and energy sectors (Robinson and others, 2017). Graphite is used in batteries, brake linings, lubricants, powdered metals, refractory applications, and steelmaking (U.S. Geological Survey, 2021). In 2020, the U.S. was 100 percent net import reliant on graphite from countries that included China, Mexico, Canada, and India (U.S. Geological Survey, 2021). Graphite has not been produced in the U.S. since the 1950s. Graphite occurs in the U.S. as disseminated flake graphite deposits and as graphite veins. Globally, most currently mined flake graphite deposits contain at least 8 to 12 percent graphitic carbon in deposits larger than 0.5 million metric tons (Robinson and others, 2017). In comparison, the Graphite Creek deposit in Alaska contains a measured and indicated resource of more than 10 million metric tons with 7.8 percent graphite plus an inferred resource of more than 90 million metric tons with 8 percent graphite (King and others, 2019). Graphite One Inc. plans to decide whether to move the Graphite Creek deposit into production after an updated prefeasibility study is completed in early 2022. The entries and descriptions in the database were derived from published papers, reports, data, and internet documents representing a variety of sources, including geologic and exploration studies described in State, Federal, and industry reports. Resources extracted from older sources might not be compliant with current rules and guidelines in minerals industry standards such as National Instrument 43-101 (NI 43-101). The presence of a graphite mineral deposit in this database is not meant to imply that the deposit is currently economic. Rather, these deposits were included to capture the characteristics of the largest graphite deposits in the United States. Inclusion of material in the database is for descriptive purposes only and does not imply endorsement by the U.S. Government. The authors welcome additional published information in order to continually update and refine this dataset.

The preparation of this map was preceded by the preparation of the Mineral Resources Cadastre of the Republic of Srpska. The process of creating the cadastre itself is an extensive multi-year work that includes a field work as well as electronic data processing. The data from the cadaster are ploted on the previously prepared Geological map and the result of this process is the Mineral Resources map of the Republic of Srpska.

Open dataset contains basic information on all registered reserved mineral deposits (B) and approved prognosticated mineral resources of reserved (P) and non-reserved (R) minerals in the territory of the Czech Republic. The Ministry of the Environment issues a certificate of reserved deposit if a reserved mineral is found in quantity and quality that allow its accumulation to be reasonably expected. The data of subregisters B, P, R are part of the Raw Materials Information System (SurIS) of the Czech Geological Survey.

Since 1999, the Geologic Survey of Baden-Württemberg publishes a statewide geological map series 1 : 50 000 "Karte der mineralischen Rohstoffe 1 : 50 000 (KMR 50)". On it, the distribution of near-surface mineral raw material prospects and occurrences (mainly) and deposits (subordinate) is shown. This continuously completed and updated map currently covers around 60% of the federal state. It is the base for the regional associations in the task of mineral planning.

The prospects and occurrences are classified according to different raw material groups (e.g. raw material for crushed stone (limestone, igneous rocks, metamorphic rocks, sand and gravel), raw materials for cement, dimension stone, high purity limestone, gypsum ...). Their spatial delineation is based on various group-specific criteria such as minimum workable thickness, minimum resources, ratio overburden/workable thickness, and so on. It is assumed that they contain deposits as a whole or in parts. In the vast majority of cases, the data is not sufficient for the immediate planning of mining projects, but it does facilitate the selection of exploration areas.

The name of each area (e.g. L 6926-3) consists of three parts. L = roman rnumeral fo 50, 6926 = sheet number of the topographic map 1 : 50 000, 3 = number of the area/mineral occurrence shown on this sheet.

Co-occurring land-use conflicts, e.g. water protection areas and nature conservation areas, forestry and agriculture, are not taken into account in the processing of KMR 50. Their assessment is the task of land use planning, the licensing authorities and the companies interested in mining.

The data is stored in the statewide raw material area database "olan-db" of the LGRB.

This data release contains the U.S. salient statistics and world production data extracted from the tables and figures of the USGS Mineral Commodity Summaries 2023 that give an overview of the U.S. mineral industry in 2023.

Mineral Land Classification studies are produced by the State Geologist as specified by the Surface Mining and Reclamation Act (SMARA, PRC 2710 et seq.) of 1975. To address mineral resource conservation, SMARA mandated a two-phase process called classification-designation. Classification is carried out by the State Geologist and designation is a function of the State Mining and Geology Board. The classification studies contained here evaluate the mineral resources and present this information in the form of Mineral Resource Zones. The objective of the classification-designation process is to ensure, through appropriate local lead agency policies and procedures, that mineral materials will be available when needed and do not become inaccessible as a result of inadequate information during the land-use decision-making process.

The data set marpits1 is an ArcInfo coverage of point features representing pit locations and attribution data captured from an atlas of map sheets and pit data sheets titled "A Materials Inventory of Maricopa County [Arizona]" by the Arizona Highway Department (AHD), now named the Arizona Department of Transportation (ADOT), hereafter referred to as the 'Source'. Pit locations were represented by point symbols in the Source map sheets. Points were digitized from the Source map sheets. Selected attribute data were collected from the Source pit data and map sheets. In the Source introduction it states:

"The pit location maps show the location of all pits bearing Materials Services serial numbers. Other sources are not shown. The plotted locations are as close as possible to the true location as the scale of the map will allow." The point attribute data, captured from the Source pit data sheets are "designed to show test results (sieve analysis, plasticity index, and abrasion) for the usable material within each ADOT pit."

The Gold suitable geological layers for the African continent provides information on the locations where artisanal and small-scale gold mining (ASgM) is geologically possible. ASgM requires the presence of gold in the ground or rivers. This database builds upon this geological necessity, recent research in geology, and the latest mapping of the contours, age, and chemical composition of the African geological bedrocks.Latest datasetThe folder Gold_suitable_geology contains the raw gold-suitable geological layers for Africa. For users familiar with the PRIO-GRID data structure (Tollefsen et al. 2012), the folder Gold_suitable_PRIOgrid provides each PRIO-GRID cell ID alongside its corresponding gold-suitability classification. This version: March 2022.Companion paperThe first version of this database was initially constructed to conduct the analysis reported in "Artisanal mining in Africa; Green for gold?" (The Economic Journal, forthcoming).

MIN4EU DB consists of two parts: Minerals Inventory data and Minerals Yearbook data. Minerals Inventory covers mineral occurrences and mines in Europe (onshore). The European Union has identified security of supply, improving environmental management and resource efficiency as key challenges for the raw materials sector. Data on the location and spatial distribution of primary and secondary raw materials in relation to exploration, exploitation, production and trading activities form the basis for decision-making in government and industry. Given the dynamic nature of such data, regular updates of comprehensive, reliable and harmonized information across borders are required, as there are several sources of non-harmonized data with different coverages developed over the last decades by national and international projects for different purposes. Data have been prepared and collected in the projects Minerals4EU, EURare, ProSUM, ORAMA, RESEERVE and MINTELL4EU, and others and are shared in the European Geological Data Infrastructure (EGDI).

This U.S. Geological Survey (USGS) data release provides the descriptions of 11 U.S. sites that include mineral regions, mines, and mineral occurrences that contain enrichments of niobium (Nb). To be included in this data release, a site must have a contained resource and (or) past production of Nb metal greater than 10,000 metric tons, which was the approximate consumption of Nb in the U.S. in 2019 (U.S. Geological Survey, 2020). Sites in this dataset occur in Alaska, Arkansas, Colorado, Nebraska, and Texas. Niobium primarily occurs in oxide minerals of the pyrochlore group, which are most commonly found in carbonatites and alkaline granite-syenite complexes. Globally, the largest Nb deposits occur in Brazil and Canada. In Brazil, the Barreiro carbonatite complex hosts the Araxá deposit that contains more than 460 million metric tons of ore with an average grade of 2.48 percent Nb2O5 (Schulz and others, 2017). The world’s leading producer of Nb outside of Brazil is the Niobec Mine in Quebec, Canada. The Niobec deposit occurs in the Saint-Honoré carbonatite complex, where pyrochlore is the main niobium-bearing mineral; the ore body contains more than 400 million metric tons with an average grade of 0.42 percent Nb2O5 (Schulz and others, 2017). In comparison, the largest known Nb deposit in the U.S. is the Iron Hill deposit in Colorado, which has been prospected for titanium, Nb, rare earth elements and thorium. There are no current U.S. producers of Nb, but the Elk Creek project in Nebraska is in the furthest stage of development. If Elk Creek comes online, it will be the first recorded producer of Nb in the U.S. since the 1950s. Niobium is necessary for strategic, consumer, and commercial applications. The primary use for Nb is for the production of high strength steel alloys used in pipelines, transportation infrastructure, and structural applications (Schulz and others, 2017). As of 2019, the U.S. maintains a history of being 100 percent net import reliant on Nb from countries, such as Brazil and Canada. Niobium is imported to the U.S. as Nb minerals, oxides, and ferroniobium (U.S. Geological Survey, 2020). The entries and descriptions in the database were derived from published papers, reports, data, and internet documents representing a variety of sources, including geologic and exploration studies described in State, Federal, and industry reports. Resources extracted from older sources might not be compliant with current rules and guidelines in minerals industry standards, such as National Instrument 43-101 (NI 43-101). The inclusion of a Nb mineral deposit in this database is not meant to imply that the deposit is currently economic. Rather, these deposits were included to capture the characteristics of the largest Nb deposits in the United States. Inclusion of material in the database is for descriptive purposes only and does not imply endorsement by the U.S. Government.
