About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.
Mine Info
Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Workings): Workings / Exploration = Work restricted to surface sampling of outcrop during geologic mapping by USGS in the late 1970s.
Comment (Deposit): Other Comments = Site is in Gates of the Arctic National Park.
Comment (Geology): Geologic Description = This occurrence consists of a grab sample of pyrite-bearing oxidized zones in calcareous siltstone of the Devonian Skagit Limestone. Assays of the sample showed 300 ppm As and 300 ppm Sb (Nelson and Grybeck, 1980; Grybeck and Nelson, 1981). The occurrence apparently is only of local extent.
Comment (Reference): Primary Reference = Grybeck and Nelson, 1981
Comment (Exploration): Status = Inactive
