The Bear claims 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 = Gold-bearing stockwork veins that contain arsenopyrite.
Comment (Geology): Geologic Description = The following geologic description is taken from Freeman and others (1988, p. 16): Mineralization in the roadcut of the Steese Highway within the Bear claims consists of massive to disseminated arsenopyrite and lesser pyrite. The sulfide minerals are hosted by a sequence of chloritic greenschist overlain by black calcareous, graphitic schist overlain by micaceous quartzite. The sequence is folded into open folds whose axes plunge gently south with wavelengths of approximately 150 feet and amplitudes of approximately 30 feet. The crests of anticlines are cut by stockwork quartz veins stained by abundant scorodite. The rocks are pervasively oxidized along vertical shear zones which strike N 40 E. The shears contain oblong fragments of highly altered granite which are also mineralized with arsenopyrite and pyrite and are heavily stained with scorodite. A sixty-five foot section of one of the most highly mineralized anticlinal structures was channel sampled at five foot intervals. the maximum gold value for these channel samples is 0.092 ounces per ton, but several others have gold values ranging from 0.012 to 0.017 ounces per ton.
Comment (Exploration): Status = Inactive
Comment (Workings): Workings / Exploration = Channel sampled in 1988 (Freeman and others, 1988).
Comment (Reference): Primary Reference = Freeman and others, 1988.
