The Murray Gulch and New York 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 = Active

Comment (Workings): Workings / Exploration = Surface trenches and shaft into frozen ground.

Comment (Production): Production Notes = About 1,500 oz Au produced prior to about 1955; further unrecorded production 1979-81.

Comment (Reference): Primary Reference = Maddren, 1915, p. 353-355

Comment (Geology): Geologic Description = Gold occurs downstream from hypabyssal rhyolite dikes that cut Kuskokwim Group sedimentary rock in the upper part of Murray Gulch. Maddren (1915) reported course gold from deep gravel beneath the stream and from bench gravels about 70 ft above present flood plain. Bench gold is rough.

Comment (Deposit): Other Comments = Stream gradient about 180 ft/mi.

Comment (Deposit): Model Name = Placer: stream; bench

Comment (Geology): Age = Tertiary/Quaternary
