California Creek

The California Creek 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.

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 = Active?

Comment (Workings): Workings / Exploration = In the Turnagain Arm area, the first gold north of the arm was found in 1895 by F.J. Perry and Christopher Spillum, on California Creek (Moffit, 1906). The placer deposits were worked intermittantly, with hand placer operations, between 1898 and 1914. In the late 1920s, work was begun along the creek in preparation for a mine that was to be in place by 1930. However, late in 1931, the operators decided to abandon the project. Since 1975 some hand placer activity has also occurred. ? Jasper (1967) reported that stream sediment concentrates collected from the lower stream course contained 20 grains of scheelite, about 5 percent magnetite, a little pyrite, and about 20 grains of zircon. Two 0.1 cubic yard bench samples collected at the canyon mouth yielded 0.0006 and 0.0007 oz Au/cubic yard (Jansons and others, 1984). Jansons and others (1984) indicated a low to moderate mineral development potential for a small scale mechanized operation at the lower end of the creek, and for hand placer mining and suction dredging operations.

Comment (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a)

Comment (Deposit): Other Comments = Most of the mining activity along California Creek occurred in the Seward D-6 1:63,360-scale quadrangle.

Comment (Production): Production Notes = Total estimated production since 1898 is 400 oz (Jansons and others, 1984).

Comment (Reference): Primary Reference = Moffit, 1906

Comment (Geology): Geologic Description = Erratically distributed placer gold occurs in the California Creek valley. The creek occurs in a steep, narrow avalanche debris-filled glacial valley having little accumulation of gravel. The gravels exposed along California Creek contain considerable clay and are probably glacial till. An alluvial fan at the lower end of the creek contains fine-grained gold. The middle section of the creek is in a bedrock gorge. Grades are reported to be extremely variable (Moffit, 1906; Jansons and others, 1984).? the bedrock through which California Creek flows are Late Cretaceous metasedimentary rocks of the Valdez Group. The metasediments are locally intruded by felsic dikes and plugs. Creek float consists of graywacke, argillite, and granite. Jasper (1967) reported that stream sediment concentrates collected from the lower stream course contained 20 grains of scheelite, about 5 percent magnetite, a little pyrite, and about 20 grains of zircon. Two 0.1 cubic yard bench samples collected at the canyon mouth yielded 0.0006 and 0.0007 oz Au/cubic yard (Jansons and others, 1984).

Comment (Geology): Age = Quaternary
