The Nelson 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 (Geology): Age = Cretaceous
Comment (Exploration): Status = Inactive
Comment (Commodity): Ore Material = Copper (native)
Comment (Geology): Geologic Description = Prospect lies on NE limb of a broad NW-trending syncline cut by two major faults: a thrust fault striking about N 45 W and dipping SW along which the Nikolai Greenstone has overridden a section of Chitistone Limestone; and a high-angle normal fault striking about N 25 E. Stringers and discontinuous masses of disseminated to massive chalcocite and covellite and minor enargite, bornite, chalcopyrite, malachite, and native copper as replacements of limestone and dolomite along steeply inclined narrow fissures and bedding planes. Prospect is in near-basal part of a faulted block of Upper Triassic Chitistone Limestone. Local faulting and shearing.
Comment (Production): Production Notes = Minor production 1929-1930.
Comment (Reference): Primary Reference = Bateman, 1932
Comment (Workings): Workings / Exploration = Explored by surface pits and 5 short adits on 4 levels. About 1,100 ft of underground workings driven between 1929 and 1930; 3 adits were still accessible in 1951. Also explored by diamond drilling. Chip samples across massive sulfide veins assayed > 2 percent Cu, 0.3 percent As, 50 ppm Ag, (MacKevett and Smith, 1968). Type of workings: Surface and underground
Comment (Commodity): Ore Material = unknown Ag minerals.
Comment (Commodity): Ore Material = unknown Ag minerals.
Comment (Deposit): Other Comments = See also: Radovan (MC160- MC078) and Kennicott (MC003) deposits.
Comment (Deposit): Model Name = Basaltic Cu
