The Bear 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 (Workings): Workings / Exploration = No descriptions of workings given. A little gold was reported to have been recovered using an arrastre for milling.

Comment (Reference): Primary Reference = Becker, 1898

Comment (Deposit): Model Name = Chugach-type low-sulfide gold-quartz vein (Bliss, 1992; model 36a.1), turbidite-hosted gold vein.

Comment (Geology): Geologic Description = At this site a quartz vein striking N. 25 W. and dipping 40 southwest cuts Cretaceous schist or slate (Becker, 1898). The vein carries arsenopyrite, pyrite, and free gold and varies in thickness from a few inches to 6 feet, averaging 2 1/2 feet. Quartz stringers parallel to the main vein occur in the surrounding country rock. Acidic dikes occur in the vicinity. This vein may be on the same structure as the Dan (KD004).

Comment (Deposit): Other Comments = No additional information is available since Becker's description.

Comment (Geology): Age = Cretaceous or younger
