The Finnbear 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 = Probably inactive

Comment (Reference): Primary Reference = Bureau of Mines, 1995

Comment (Production): Production Notes = No production

Comment (Geology): Geologic Description = Only information is reported by the U.S. Bureau of Mines (1995) as a lode gold deposit.? the geologic map (Nelson and others, 1983) indicates undivided Quaternary deposits in the area of the occurrence. Bedrock is about 2.8 km north and south of the occurrence. To the north, the bedrock consists of Tertiary volcanic rocks (Tv) and Cretaceous to Tertiary medium-grained granite (TKi11). The volcanic rocks include rhyolitic breccia, ash-flow tuff, flows, felsic intrusive rocks, and subordinate mafic to intermediate flows. Potassium-argon ages for Unit Tv range from 56.2 to 62.7 m.y. (Eakins and others, 1978). To the south, the bedrock is Tertiary mafic to intermediate volcanic flows (Nelson and others, 1983; unit Tvf).?

Comment (Deposit): Other Comments = MAS/MILS sequence number 0020930008 (Bureau of Mines, 1995).

Comment (Deposit): Model Name = Unknown

Comment (Reserve-Resource): Reserves = No reserves

Comment (Workings): Workings / Exploration = Unknown

Comment (Geology): Age = Unknown.
