The Lichen is a gold, copper, and silver 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 = Host rocks are meta-volcanics and quartz sandstone of Paleozoic age. Veins and disseminations of sulfides in a zone in a mafic volcanic flow; mineralized zone about 6 ft by 3,000 ft (2 m by 900 m), appears confined to a single flow. Host rocks have undergone greenschist-facies metamorphism.
Comment (Deposit): Model Number = 22a, or 22c, or 36a?
Comment (Reference): Primary Reference = Smith and others, 1975
Comment (Workings): Workings / Exploration = Two trenches yielding samples showing up to 4.5% Cu, 16 ppm Au, and 68 ppm Ag (Smith and others, 1975).
Comment (Deposit): Model Name = Volcanic-hosted copper, or polymetallic vein, or gold-quartz vein? (Cox and Singer, 1986; model 22a, or 22c, or 36a?)
Comment (Exploration): Status = Inactive
