The Unknown is a gold 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 (Workings): Workings / Exploration = One sample assayed 0.28 ounce per ton gold, 3.50 ounces per ton silver, 14 percent arsenic, and trace copper.
Comment (Deposit): Model Name = Chugach-type low-sulfide gold-quartz veins (Bliss, 1992; model 36a.1).
Comment (Deposit): Other Comments = Site is on land conveyed to the Koniag Corporation.
Comment (Reference): Primary Reference = Rose and Richter, 1967
Comment (Geology): Geologic Description = At this locality Tertiary granodiorite along a beach is cut by iron-stained quartz veins for several hundred feet. The veins average N. 75 W. in strike and contain pyrite and pyrrhotite in local abundance. Some of the veins are vuggy. A sample collected here by Rose and Richter, 1967, assayed 0.10 ounce per ton gold, 3.50 ounces per ton silver, trace copper, and 14 percent arsenic.
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Tertiary
