  Description
    Abstract:
        Mine locations from the U.S. Bureau of Mines Mineral
        Information Location System (MILS) database. Provided to
        NRIS by Frances Baker of the Spokane office (509-353-2738 or
        509-353-2712). This data was provided to BOM from many State
        and Federal agencies, and the coordinates come from sources
        of varying accuracy. The attributes included here are a
        subset of those available from USBOM. Data from BOM's
        "one-liner" report on 9/1/1992. 
    Purpose:
        Mine information database.
