Nelson Creek

The Nelson 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 = Epigenetic mineralization in metamorphic rocks of Seward Peninsula is primarily of Cretaceous age. Some lode gold deposits on southern Seward Peninsula are mid-Cretaceous in age (see Midnight Mountain, BN047).

Comment (Deposit): Model Name = Quartz veins and segregations in metasedimentary rocks.

Comment (Geology): Geologic Description = An abandoned placer cut on a north bench just above the mouth of Nelson Creek exposes schist bedrock containing quartz segregations and boudins. A sample of boudined quartz and some enclosing schist assayed 0.02 ounces/ton Au, 0.10 ounces/ton Ag, 0.05 % Cu, 0.05 % Pb, and 0.05 % Zn (Herried, 1966, Table 1). Herried (1966) also reported this analytical result as $0.70 per ton gold (not 0.70 ounces/ton Au as restated by Cobb, 1975, and Hudson and others, 1977). The bedrock here is locally bleached and cut by a clay altered zone. Bedrock of the area is a metasedimentary schist and marble sequence of Lower Paleozoic age (Till and others, 1986).

Comment (Reference): Primary Reference = Herried, 1966

Comment (Workings): Workings / Exploration = An abandoned placer cut on a north bench just above the mouth of Nelson Creek exposes schist bedrock containing quartz segregations and boudins.

Comment (Exploration): Status = Inactive
