The Pmrgx-9 is a gold and copper mine located in Alaska.
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 (Geology): Geologic Description = At this site altered pyritized dacite(?) intrudes sedimentary rocks of the Paleocene to Eocene Tolstoi Formation (Wilson and others, 1995). Andesite sills and 3-inch-wide quartz veins were also reported in the area (Wilson and others, 1988). Seven samples collected by the U.S. Geological Survey in the mid-1980's were reported to be anomalous in arsenic, copper, gold, and lead (Wilson and others, 1988).
Comment (Workings): Workings / Exploration = Rock samples 82ASh6, 82AWs7-7a, 82Ayb1a-1c, and 82ADt43 were reported to be anomalous in arsenic, copper, gold, and lead (Wilson and others, 1988).
Comment (Geology): Age = Paleocene or younger.
Comment (Deposit): Other Comments = This site is is located on land selected by the Aleut Corporation.
Comment (Reference): Primary Reference = Wilson and others, 1988
