The Pinnell River 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 = Inactive

Comment (Geology): Geologic Description = A small orange gossan is developed in black dolomitic marble just above the Fairhaven ditch at an elevation of 750 feet. The marble is partially replaced by disseminations and stockwork veinlets of quartz and veinlets of fuchsite (Herried, 1966). A gossan sample contained 0.02 ounces/ton Au, 0.023 ounces/ton Ag, 0.05 % Cu, 0.05 % Pb, 0.05 % Zn, and 0.5 % Cr (Herried, 1966, Table 1). Most of the bedrock in the area is a metasedimentary schist and marble sequence of Lower Paleozoic age (Till and others, 1986).

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 (Reference): Primary Reference = Herried, 1966

Comment (Commodity): Gangue = Fuchsite

Comment (Deposit): Model Name = Vein and replacement in marble ?

Comment (Workings): Workings / Exploration = Small, hand dug prospecting pits may be present.
