The Mystery 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.
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 (Reference): Primary Reference = Collier and others, 1908
Comment (Workings): Workings / Exploration = Small-scale mining started in the 1900's and some dredging operations took place up to 1914 (Cobb, 1978, OF 78-181).
Comment (Geology): Geologic Description = Dredging was reported to have taken place 3 miles above the mouth (Chapin, 1913); the gravels here were 2 to 15 feet thick on a clay false bedrock. One mile above the mouth, gravels were 7 feet thick and the pay was in the lower 3 feet. Mud Creek, a headwater tributary of Mystery Creek, contained coarse, rough gold in 3 to 4 feet of angular schist gravel and in 3 to 4 foot-deep crevices in schist bedrock (Collier and others, 1908). Mud Creek gravels were overlain by 2.5 feet of muck and sthe recovered gold was coarse, very rough, spongy, and somewhat rusty. Bedrock is calcareous mica schist with small quartz stringers (Collier and others, 1908); impure schistose Ordovician marble occurs in headwater parts of the area (Till and others, 1986).
Comment (Deposit): Model Name = Placer Au-PGE (Cox and Singer, 1986; model 39a).
Comment (Geology): Age = Quaternary.
