Mineral Information Layer for Oregon-Release 4 (MILO-4)
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 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. 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!
The purpose of this MILO-Release 4 is for use as reference material supporting local- to statewide-scale mineral resource and environmental assessments. These data provide a searchable catalogue with links to supporting digital documentation that allows users to extract, research, and display historical mining and mineral resource information.
This update and release of MILO-4 was supported through a grant from the National Geological and Geophysical Data Preservation Program (NGGDPP) under cooperative agreement number G23AP00218-01 (2023). Additional funds were provided by the State of Oregon.

The PLSS code was created and consists of the township and range down to the quarter-quarter section. No duplicates were found.
To make sure each record successfully and correctly joined to a PLSS point using the PLSS code, multiple iterations of joining tests were undertaken. After one join test, the PLSS code for the records that did not match to a point would be modified, so that in the next test, they would potentially join successfully. This was continued until all records matched with a point location. Next, the PLSS points dataset that matched at least one record was checked for duplicate points and/or points with duplicate PLSS codes. The duplicate points were then removed.
This feature class only contains center points for PLSS, county, or the state of Oregon locations related to Assay Returns records.
PLSS center points are derived from the most recent published digital second division survey for the state of Oregon at the time of this project. Manual of Surveying Instructions for public land surveys have changed and evolved through the course of time. Therefore, actual location of assay center points may not exactly match the surveyed location at the time of collection and/or submission of samples.
The PLSS data was the most-detailed location information on each assay PDF, the BLM OR Cadastral PLSS Second Division polygon dataset was downloaded from the BLM Geospatial Business Platform and used to designate assay point locations. The cadastral dataset was converted from polygons to points (centroids within) and a PLSS code was created within a field in the point attribute table. This field consists of the township and range down to the quarter-quarter section. This PLSS code format was replicated in the assay table using each assays PLSS location information. The code information was used as a primary key for relating the cadastral point locations to the assay table records.
