The Big Blue 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 = In 1931, the Big Blue lead consisted of a number of shallow shafts and pits (Hill, 1933, p. 148).
Comment (Geology): Geologic Description = Material on the dump suggests the ore zone consisted of a fault zone of crushed schist, quartz, and gouge (Hill, 1933, p. 148). The vein strikes N. 27 E., but a dip could not be determined at the time of Hill's visit in 1931, due to the collapse of the prospect pits. The bedrock is mainly biotite schist; many pieces of quart-mica schist are on several of the dumps. The Big Blue prospect is in a unit of quartz-muscovite schist, quartzite, and chlorite-quartz schist of the Fairbanks Schist as mapped by Newberry and others (1996).
Comment (Deposit): Model Name = Schist-hosted gold-quartz vein
Comment (Reference): Primary Reference = Hill, 1933
Comment (Exploration): Status = Inactive
