The Mother Lode 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 (Production): Production Notes = No production reported.
Comment (Reference): Primary Reference = Smith, 1913 (B 525)
Comment (Workings): Workings / Exploration = Two shafts were sunk on this prospect (Smith, 1913; B 525, p. 180). The western shaft was 147 feet deep, with a short crosscut at the bottom running eastward. The eastern shaft, 200 paces east of the western shaft, was sunk 215 feet. The first 60 feet was sunk through muck and the rest through rock with no intervening gravel. The two shafts were nearly filled with water in 1912 (Smith, 1913; B 525, p. 180).
Comment (Geology): Geologic Description = Material on dumps is graphitic limestone heavily impregnated with disseminated sulfides, mainly pyrite with some chalcopyrite and arsenopyrite (Smith, 1913; B 525, p. 194). Smith (1913, B 525) also reported post-sulfide faulting.? Two shafts were sunk on this prospect (Smith, 1913; B 525, p. 180). The western shaft was 147 feet deep, with a short crosscut at the bottom running eastward. The eastern shaft, 200 paces east of the western shaft, was sunk 215 feet. The first 60 feet was sunk through muck and the rest through rock with no intervening gravel. No production has been reported.
Comment (Deposit): Model Name = Polymetallic carbonate replacement.
Comment (Exploration): Status = Inactive
