Quartz Creek

The Quartz 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 (Geology): Age = Quaternary

Comment (Exploration): Status = Inactive

Comment (Workings): Workings / Exploration = Open-cut placer mining operations have occurred at several places along about 7,000 feet of the creek.

Comment (Reference): Primary Reference = Cobb, 1975 (OFR 75-429)

Comment (Geology): Geologic Description = This part of Quartz Creek drains across schist in the upper part and Pliocene-Pleistocene Kougarok gravel in the lower part (Hopkins, 1963; Sainsbury and others, 1969; Till and others, 1986). Gold was discovered here in 1999 or 1900 (Brooks and others, 1901; Collier and others, 1908). Even the first workers (Brooks and others, 1901) suspected that at least some of the gold was reworked from Kougarok gravel which has been shown to contain small amounts of gold (Sainsbury and others, 1969; Sainsbury, 1975). Gravel mined at the mouth of Dahl Creek was 2 to 3 foot-thick on a blue clay false bedrock (Collier and others, 1908). The medium coarse gold here probably came from Dahl Creek (BN006). However, the best placers were reported to be on bedrock in the upstream parts of the creek. All bedrock in the area is part of a Lower Paleozoic metasedimentary assemblage (Sainsbury and others, 1969; Till and others, 1986). Sainsbury and others (1969) emphasize that gold placers in this area are most strongly associated with exposures of the metamorphic bedrock assemblage rather than with Kougarok gravel.

Comment (Deposit): Other Comments = Unnamed tributaries to Quartz Creek are reported to have scheelite in placer concentrates (Anderson, 1947).

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