The Unnamed (north of Simeon Bight) is a gold 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 = The rocks at this site are basaltic tuffs and flows interbedded with ash and crystal-lithic tuffs of the Eocene to Oligocene Popof volcanic rocks (Wilson and others, 1995). Two distinct areas of alteration are present. The westernmost is a north-trending 5,000- by 1,000-foot zone of silicification. Approximately 1,000 feet to the east is a 2,000- by 2,000-foot zone of mixed silicified and argillized rock (Ellis and Apel, 1989). Pyrite is the only sulfide reported. Grid sampling of soil and rocks revealed only scattered, low-order gold anomalies; however, widespread arsenic and mercury anomalies were outlined. The prospect was explored by 5 drill holes. Three were drilled on a gold-arsenic anomaly just southwest of a 4,000-gamma magnetic low. This drilling penetrated rock carrying scattered gold values of 20 to 200 ppb and localized base metal values of 100 to 2,500 ppm copper, 100 to 800 ppm lead, and 200 to 700 ppm zinc (Ellis and Apel, 1989). All five drill holes cut strong to pervasive silicification, argillization, pyritization, and localized solfataric alteration marked by native sulfur.
Comment (Deposit): Other Comments = This site is located on land patented by, or interim-conveyed to, the Aleut Corporation.
Comment (Workings): Workings / Exploration = In 1989 Battle Mountain Exploration Company mapped this prospect, collected 250 rock and 500 soil samples, conducted VLF-EM surveys, power-augered 97 holes, and drilled five core holes for a total of 2,795 feet (Ellis and Apel, 1989; 1990). Fifty-five rock samples were taken in 1990. Only scattered low-level gold values were found.
Comment (Geology): Age = Eocene or younger.
Comment (Reference): Primary Reference = Ellis and Apel, 1989
