Mines and Mineral Occurrence Sites
Sites where earth resources have been demonstrated. This includes metallics, industrial minerals and construction materials, but excludes oil, gas and groundwater resources which are recorded in OILGAS and BORES datasets. OILGAS will be available for external users within Petroleum Mapshare. It is thought that groundwater resources will be available to external users within a CLPR (Catchment and Land Protection) Mapshare View. The data is derived from Minerals and Petroleums RDBMS, which is known as VICMINE. Information on each site has been compiled mostly from historical literature, with only selected major sites visited in the field. NOTES CONCERNING GEOVIC "Mines and Mineral Occurrence" DISPLAY The type of mine/mineral occurrence displayed varies with the scale of the map view. Major and Intermediate size mines are displayed at all scales. Minor and Unknown size Mines are displayed at scales ranging from 1:1 to 1:500,000 MAJOR is for mine_size greater than= 85000000 MINOR is for mine_size less than 8500000 INTERMEDIATE is for mine_size between the two UNKNOWN is when the mine_size is unknown MINE_SIZE (better name would be MINE_VALUE) is a calculated dollar amount based on the total production and resource for each commodity multiplied by the commodity price (NOTE: these commodity prices have not been updated in some time eg: as of 13/1/2013 the gold price per ounce used was $526.70 - April 1985 prices) NOTES CONCERNING GEOVIC "Deposit Styles" DISPLAY A number of deposit style layers exist in GeoVic. The layers are based on particular values of the dep_style attribute - within this dataset. The dep_style attribute contains the results of classifying the mineral deposits of Victoria east of approximately 142°30' and west of 145°30', but excluding the Willaura (7422) 1:100 000 map sheet area. The classification is described in detail in Moore, D.H., 2007. "Classifying gold deposits in central and western Victoria, Australia. GeoScience Victoria Gold Undercover Report". GENERAL NOTES CONCERNING GEOVIC Refer to Mineral Regions 1M (MINERAL) for extent of brown and black coal fields, Heavy Mineral Sands 1M (MINSAND1M) for extent of strandline mineral sand deposits, and Heavy Minerals Sands WIM 1M (MINSAND1M) for extent of WIM style mineral sand deposits.

Mineral Occurrences Data (Mineral Resources Tasmania)
공공데이터포털
Mineral occurrences, including operating and abandoned mines, located in Tasmania, with summary mineral occurrence data, derived from the Mineral Occurrence Database, which is a component of the Tasmanian Information on Geoscience and Exploration Resources (TIGER) system; administered by Mineral Resources Tasmania (MRT). Mineral occurrences include operating and abandoned mines, prospects, mapped occurrences and mineral fields or mineralised areas. Mineral occurrences are shown subdivided by commodity type, which largely corresponds to the mineral categories defined in the Mineral Resources Development Act 1995; Fuel Minerals, including geothermal (Categories 2, 4 and 6), Construction Minerals (Category 3), Industrial minerals (Category 5) and metallic minerals (Category 1). Alluvial, placer and man-made (tailings dam) occurrences are shown separately (commodities are mineral Categories 1 and 5) and occurrences (generally abandoned mine workings) where there are no records of the commodity of interest, are shown as unknown. The summary Mineral Occurrence data includes: the Mineral occurrence name (note that an occurrence may have multiple names or aliases), the commodity type (as defined above), the nature of the occurrence (e.g., mine or prospect, mineralised area), the commodity or commodities present, the geological unit that hosts the occurrence and the positional accuracy of the record. A Details field provides a link to a Mineral Occurrence Details page where further information, including references and public domain resource figures, may be available.

GIS and Data Tables for Focus Areas for Potential Domestic Nonfuel Sources of Rare Earth Elements
공공데이터포털
In response to Executive Order 13817 of December 20, 2017, the U.S. Geological Survey (USGS) coordinated with the Bureau of Land Management (BLM) to identify 35 nonfuel minerals or mineral materials considered critical to the economic and national security of the United States (U.S.). Acquiring information on possible domestic sources of these critical minerals is the basis of the USGS Earth Mapping Resources Initiative (Earth MRI). The program, which partners the USGS with State Geological Surveys, federal agencies, and the private sector, aims to collect new geological, geophysical, and topographic (lidar) data in key areas of the U.S. to stimulate mineral exploration and production of critical minerals. The first phase of Earth MRI focuses on the study of rare-earth elements (REE). The USGS has identified broad areas within the U.S. to target acquisition of geologic mapping, geophysical data, and (or) detailed topographic information to aid research, mineral exploration, and evaluation of REE potential in these areas. Focus areas were defined using existing geologic data on known REE deposits in the U.S. The focus areas are provided as geospatial data supported by tables that summarize what is known about the REE potential and brief descriptions of data gaps that could be addressed by the Earth MRI program. A full discussion of Earth MRI and the rationale and methods used to develop the geospatial data are provided in the following report: Hammarstrom, J.H., and Dicken, C.L., 2019, Focus areas for data acquisition for potential domestic sources of critical minerals—Rare earth elements, chap. A of U.S. Geological Survey, Focus areas for data acquisition for potential domestic sources of critical minerals: U.S. Geological Survey Open-File Report 2019–1023, 11 p., https://doi.org/10.3133/ofr20191023A.
