Dodge Creek

The Dodge 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 (Workings): Workings / Exploration = Gold was discovered on Dodge Creek in 1915 and mining probably began in 1916 (Brooks, 1916). Mining continued intermittently until possibly as recent as 1962.

Comment (Production): Production Notes = The estimated production from Dodge Creek is 408 ounces of gold and 40 ounces of silver (Bundtzen and others, 1987).

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

Comment (Exploration): Status = Probably inactive

Comment (Geology): Age = Quaternary. The placer gold is probably derived from Cretaceous or Tertiary intrusive rocks (Bundtzen and others, 1987).

Comment (Geology): Geologic Description = The bedrock in the vicinity of Dodge Creek consists of sandstone, shale, and siltstone, and several small monzonite intrusive bodies (Chapman and others, 1985).? Gold in Dodge Creek is reportedly deep (Brooks, 1916). Heavy minerals in placer concentrates include magnetite, ilmenite, siderite, pyrite, amphibole, pyroxene, and zircon (Bundtzen and others, 1987). The source of the gold may be bimodal dike swarms, peraluminous rhyolite, and alkali-calcic monzonitic intrusive rocks in the Ophir area (Bundtzen and others, 1987).?

The estimated production from Dodge Creek is 408 ounces of gold and 40 ounces of silver (Bundtzen and others, 1987). The gold was 911 fine (Metz and Hawkins, 1981).
