Perry Creek

The Perry 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 = Late Tertiary to Pleistocene; the age of the Kougarok gravels (Hopkins, 1963).

Comment (Reference): Primary Reference = Hopkins, 1963

Comment (Workings): Workings / Exploration = These basalt-covered terrace gravels are old channels that required underground drift mining; the extent and nature of these workings are not known.

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

Comment (Geology): Geologic Description = This location includes terrace gravels on both the north and south sides of Perry Creek overlooking Pinnell River. The terrace gravels are capped by basalt flows about 200 to 250 feet vertically above the Pinnell River (Henshaw, 1910). One terrace sequence includes (bottom to top); 3 to 9 feet of gold-bearing gravel on schist bedrock, 20 feet of muck including wood fragments near the base (a 3 foot-diameter log is reported to have been encountered somewhere in the Perry Creek mine workings), 25 feet of basalt, an indeterminate thickness of nonauriferous gravel, and an indeterminate thickness of basalt (Hopkins, 1963, p. C32). Henshaw (1910) indicates that one terrace level is 52 feet higher than another in the area. The fine, bright gold here -- some nuggets worth $0.15 at $20/ounce -- was in quartz-rich gravel (Moffit, 1905). Most of the bedrock in the area is a metasedimentary schist and marble sequence of Lower Paleozoic age (Till and others, 1986). The basalt flows are part of the Pleistocene Imuruk Volcanics and the terrace gravels may be correlative with the Pliocene-Pleistocene Kougarok gravels (Hopkins, 1963).

Comment (Exploration): Status = Inactive
