Hidden Creek

The Hidden 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 (Reference): Primary Reference = Moffit, 1938; Richter, 1966

Comment (Workings): Workings / Exploration = Small placer operation (Moffit, 1938; Richter, 1966).

Comment (Geology): Geologic Description = The rocks in the area consist of Pennsylvanian to Permian volcanics of the Tetelna Formation that are intruded by monzonitic rocks of the Pennsylvanian to Permian, Ahtell pluton. The contact is broad and low angle; the Teteltna rocks form a roof cap over the pluton along Hidden Creek (Richter, 1966). Little is known about this placer deposit. The area was prospected in the early 1900's; it was restaked and prospected again after the discovery of the placer in Grubstake Gulch in 1934 (Moffit, 1938, p. 51). The placer prospect is about 3 miles below the Elizabeth, molybdenum-porphyry deposit (GU025). This porphyry was apparently not sampled systematically for gold, but Richter and Matson (1968) reported one highly anomalous stream-sediment sample with 300 ppb Au in the valley of Hidden Creek below the Elizabeth deposit and about 2.5 miles above the placer workings in Hidden Creek.

Comment (Production): Production Notes = Probably minor .

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

Comment (Geology): Age = Holocene placer.

Comment (Exploration): Status = Inactive
