The Unnamed (northeast of Avaraart Lake) is a zinc, lead, copper, 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 = Numerous prospect pits and surface mapping.

Comment (Geology): Age = Syngenetic massive sulfide in Devonian or Mississippian host rocks.

Comment (Reference): Primary Reference = Grybeck and Nelson, 1981

Comment (Geology): Geologic Description = These prospects explore a silver-basemetal volcanogenic massive sulfide deposit in a sequence of low to medium grade metamorphosed basaltic and rhyolitic rocks, submarine ash flow tuffs, and pelitic and carbonaceous sedimentary rocks known as the Ambler schist belt. The deposit is a Devonian or Mississippian in age, based on fossil evidence and U-Pb radiometric dating in the region (Hitzman and others, 1986). Rocks are commonly iron stained in the area. The deposit has been explored by numerous prospect pits and surface mapping.

Comment (Deposit): Model Name = Kuroko massive sulfide (Cox and Singer, 1986; model 28a)

Comment (Exploration): Status = Active?
