Description: The Oregon Department of Geology and Mineral Industries (DOGAMI) produced the Mineral Information Layer for Oregon-Release 4 (MILO-Release 4) as a geospatial database that stores and manages information regarding Oregon's mineral occurrences, prospects, and mines; it is the primary way in which the State extracts, researches, and displays its available historical mining and mineral resource information. This feature class shows mineral-related information for the following commodities: metals (elements, metallic, and oxides), industrial minerals (non-metallic minerals and materials, including gemstones), mineral fuel (coal and oil shale), and aggregate (sand and gravel and stone). MILO contains 24,664 mineral occurrences, prospects, and mines in Oregon. Understand that recreation in or around inactive mine sites is extremely dangerous, and can result in serious injury or death. Stay out and stay alive!

This data set represents center points of: 1) the GIS Version of the Public Land Survey System including both rectangular and non-rectangular surveys; 2) County centroid; and 3) the BLM OR jurisdictional and cartographic state perimeter for Oregon. Assay points are located by township-range-section grid where samples were in surveyed areas at the time of collection and by county and/or State of Oregon for samples obtained from unsurveyed areas. These data are related as a one to many relationship to the Assay Returns table which contains the attribute information of scanned PDF assays.
