The Unnamed (east of Mt. Recheshnoi) is a silver and 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 (Reference): Primary Reference = Randolph and Ellis, 1989
Comment (Deposit): Other Comments = This site is located on land selected by the Aleut Native Corporation.
Comment (Geology): Geologic Description = This site was reported as the Mt. Recheshnoi prospect by Randolph and Ellis (1989). The rocks consist of altered andesites of Late Tertiary to Quaternity age. The occurrence is a 500 x 2600 foot color anomaly which exhibits propylitic alteration and localized argillization. Quartz occurs both as individual veins and as stockworks. Most of the veins exhibit propylitization and pyritization envelopes up to several feet on either side. In one locality, noted by Randolph and Ellis, several inches of blue-gray pyritic clay envelops comb-structure quartz-filled joints. Six samples of clay muck and vein material contained up to 72 ppm arsenic, 186 ppb gold, 2.6 ppm mercury, 19 ppm molybdenum, and 4.7 ppm silver (Randolph and Ellis, 1989, p. 11).
Comment (Workings): Workings / Exploration = Six samples of clay and quartz collected by Battle Mountain Exploration (Randolph and Ellis, 1989) contained up to 72 ppm arsenic, 186 ppb gold, 2.6 ppm mercury, 19 ppm molybdenum, and 4.7 ppm silver.
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Tertiary or younger.
Comment (Deposit): Model Name = Hot-spring Au-Ag? (Cox and Singer, 1986; model 25a)
