Unnamed (east-northeast of Cape Kigunak)

The Unnamed (east-northeast of Cape Kigunak) 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 (Exploration): Status = Inactive

Comment (Deposit): Model Name = Creede epithermal veins? (Cox and Singer, 1986; model 25b)

Comment (Deposit): Other Comments = This site is on land selected by the Aleut Native Corporation.

Comment (Reference): Primary Reference = Christie, 1974

Comment (Workings): Workings / Exploration = The Aleut-Quintana-Duval JV sampled this site in 1974 (Christie, 1974). Best values from 10 rock samples were 66 ppm copper, 0.2 ppm gold, 28 ppm molybdenum, 1.8 ppm silver, and 116 ppm zinc.

Comment (Geology): Age = Tertiary or later.

Comment (Geology): Geologic Description = This occurrence, measuring approximately 5,000 x 3,000 feet in area, consists of quartz stockwork veins in altered diorite (Christie, 1974). The stockwork is moderately to well-developed throughout and contains composite veins up to 6 feet in thickness. The quartz veins contain minor chalcopyrite and pyrite. Disseminated pyrite is common, especially adjacent to quartz veins. The diorite exhibits propylitic alteration increasing to pervasive sericitization and silicification adjacent to the quartz veins. . The Aleut-Quintana-Duval JV collected 10 rock samples in 1974. The best metal values obtained were 66 ppm copper, 0.2 ppm gold, 38 ppm molybdenum, 1.8 ppm silver, and 116 ppm zinc (Christie, 1974).
