Stillwater Complex, Montana—logs of core drilled by Stillwater Mining Company and Anaconda Copper Corp. in the Stillwater Mine area, 1983 to 1989

Metadata Updated: July 6, 2024

This dataset includes TIFF (Tagged Image File Format) images of graphic drill core logs showing associated drill core information, a TIFF image of the explanation for the lithology and structure sections of the logs, an Esri shapefile of the locations of the drill holes, and 12 .csv files of tabular data that were compiled from handwritten drill core logs. The drill core is from the Stillwater Mine area of the Stillwater Complex, Montana and was drilled from 1983 to 1989 by the Stillwater Mining Company and Anaconda Copper Corp. The data shown in the graphic drill logs and contained within the .csv files includes lithologic, structure, percent recovery, grain size, sulfide, nickel, copper, platinum, and palladium mineralization information. The graphic drill logs were created using Golden software's Strater 5 drill core visualization software and are provided with both logarithmic and linear scales where applicable. The graphic drill logs are plotted using the depth recorded in the drill logs and do not reflect stratigraphic true thickness. All instances of question marks ("?") represent original data as written by the geologist. In areas where the hand-written notes were unreadable, the notation of "[unreadable]" was used. See USGS SIR 2014-5183 ( for report and spatial data relating to the Stillwater Complex.
