  Description:
    Abstract: The exp spatial database (shapefile) contains information about mineral exploration projects in the States of Idaho and Montana for the years 1980 through 1997.  The focus of this project was to collect information on exploration for mineral commodities with the exception of sand and gravel, coal, geothermal, and oil and gas.  Serial periodicals such as The Mining Record; annual publications such as Randols Directory of Mining; company reports; and Bureau of Mines and US Geological Survey (USGS) publications and databases, an Idaho Mineral Property Data Base developed internally by Mr. D. Boleneus, MRP, Spokane, Washington; Montana State publications; and discussions with representatives of Montana, principally the Montana Bureau of Mines and Geology and the Department of Environmental Quality were used to create the database.  There are 545 exploration sites and 49 commodities.
    Purpose: Information provided in the database can be used for a range of analyses including: identification of emerging social, economic and environmental issues pertaining to potential mineral development; analyses of the affects of legislation, affects of changes in commodity prices and advances in geologic knowledge and technology on exploration activity; estimation of recent discoveries on estimates of reserve/resource base in the United States; identification of areas of permissive geology as determined by exploration activities, and assessment of  trends in time from exploration through  permitting and development of mining properties.
    Supplemental_Information: The report by Buckingham and others, 2006, contains a shapfile consisting of 7 files (Exp.dbf, Exp.prj, Exp.sbn, Exp.sbx, Exp.shp, Exp.shp.xml, and Exp.shx), a report, this metadata, and a Microsoft Access v. 2000 database (Exp.mdb).  This metadata describes the shapefile, but also applies to parts of the Access database.  The report completely describes the Access database.  The Access database contains the source reference for each point in this shapefile.  The point locations were obtained using several different methods.  If a latitude and longitude were listed in the source, then that was used.  If the source gave some other description of the location, then the U.S Bureau of Mines Mineral Availability System/Mineral Industry Location System (MAS/MILS) was checked to determine if the exploration location was in it.  As a last resort, an interpretation was used to estimate the latitude and longitude. Any reference in this metadata to a definition source that is 'Buckingham and others' refers to the report cited in this metadata.

Data_Quality_Information:
  Logical_Consistency_Report:
    An ESRI shapefile consist of a main file, an index file, and a dBASE table. The main file is a direct access, variable-record-length file in which each record describes a shape with a list of its vertices.  In the index file, each record contains the offset of the corresponding main file record from the beginning of the main file. The dBASE table contains feature attributes with one record per feature.  The one-to-one relationship between geometry and attributes is based on record number.  Attribute records in the dBASE file must be in the same order as records in the main file. Additional files may be generated such as projection file, metadata file, etc.  
    Examples:
    Main file: Exp.shp
    Index file: Exp.shx
    dBASE file: Exp.dbf
    Projection file: Exp.prj
