This dataset depicts mineral resources in Oregon, including locations of mineral occurrence, past and current mineral producing
sites, prospecting sites, and mineral processing plants. This database contains the records previously provided in the Mineral
Resource Data System (MRDS) of USGS and the Mineral Availability System/Mineral Industry Locator System (MAS/MILS) originated
in the U.S. Bureau of Mines, which is now part of USGS. The MRDS is a large and complex relational database developed over
several decades by hundreds of researchers and reporters. This product is a digest in which the fields chosen are those most
likely to contain valid information.
