Unnamed (ridge between Butterfield and upper Bangor Creeks)

The Unnamed (ridge between Butterfield and upper Bangor Creeks) 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 (Deposit): Model Name = Metamorphosed low-sulfide Au-quartz veins?

Comment (Geology): Age = Mineralization either predates regional metamorphism or took place during a ductile stage of deformation, possibly mid-Cretaceous.

Comment (Reference): Primary Reference = This report

Comment (Workings): Workings / Exploration = Claims staking and surface prospecting appears to have taken place here before 1920.

Comment (Exploration): Status = Inactive

Comment (Geology): Geologic Description = This occurrence is at or near the crest of an antiform where intensely deformed schist contains weakly mineralized quartz, including quartz rods (Kennecott Exploration Company, written communication, 1992). The quartz rods and linear elements in the schist plunge to the north-northwest. The area was apparently prospected in the early years of the Nome district, probably before 1920; quartz rods were used as claim posts. Quartz and schist from the site contain as much as 0.02 ounce of gold per ton and hundreds of parts per million arsenic. The occurrence is of interest because it may indicate pre-metamorphism gold mineralization or mineralization during a ductile stage of metamorphism. In either case, the mineralization is older than the widespread low-sulfide Au-quartz veins of the Nome district.
