Banner Creek

The Banner 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 = Smith, 1910

Comment (Workings): Workings / Exploration = Mined by small-scale hand methods by 1906. The creek was rich compared to others in the area; 4 men sluiced for 2.5 days in 1899 and recovered $400 or about 20 ounces of gold (Brooks and others, 1901).

Comment (Exploration): Status = Probably inactive

Comment (Geology): Age = Quaternary; the numerous incised terraces along the Casadepaga River and its major tributaries indicate that more than one cycle of erosion and deposition has developed placer deposits in the area. The low elevations between 170 and 270 feet along the first 11 miles of the river, suggest that Quaternary sea level fluctuations could have influenced placer development.

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

Comment (Geology): Geologic Description = Small-scale placer mining apparently took place along most of this creek in the early history of the area (Smith, 1910). The gold was mostly coarse, had a fineness of 929, and was present in 8 to 10 feet of gravel but mostly concentrated on bedrock (Brooks and others, 1901). The creek was rich compared to others in the area; 4 men sluiced for 2.5 days in 1899 and recovered $400 or about 20 ounces of gold (Brooks and others, 1901). Bedrock in the lower part of the creek is Paleozoic marble but the headwaters are underlain by pelitic schist of possible Cambrian or Precambrian age (Till and others, 1986).
