Big River

The Big River is a copper 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 = An Aleut-Quintana-Duval joint venture examined the area in of this occurrence 1974 (Christie, 1974). Bear Creek Mining Company examined it in 1977 (Fields, 1977). The U.S. Geological Survey sampled in this general area in the mid-1980's (Wilson and others, 1988).

Comment (Reference): Primary Reference = Christie, 1974

Comment (Geology): Geologic Description = The country rocks at this site are Quaternary volcanic rocks (Wilson and others, 1995). Christie (1974) described this occurrence as disseminated pyrite in vesicular volcanic rocks. Fields (1977), however, describes a color anomaly near the head of Big River that is developed in pyritized andesites, agglomerates, acid tuffs, and sedimentary rocks. Apparently, there are several color anomalies in this area.

Comment (Geology): Age = Quaternary.

Comment (Exploration): Status = Inactive
