The Mamie Mine is a copper and 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 (Deposit): MAMIE, MT ANDREW, AND STEVENSTOWN MINES ARE COMBINED HERE AS A SINGLE DEPOSIT BECAUSE OF PROXIMITY & ESSENTIALLY IDENTICAL DEPOSIT & GELOGIC CHARACTERISTICS. ; INFO.SRC : 1 PUB LIT
Comment (Workings): MAMIE MINE HAD 3 GLORY HOLES AND 3 ADITS. MT ANDREW HAD 4 GLORY HOLES AND OVER 4000 FT OF UNDERGROUND WORKINGS. STEVENSTOWN HAD GLORY HOLES AND 1000 FT OF TUNNELS
Comment (Location): MT ANDREW IS LOCATED AT 55-31-00; 132-18-00 LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).
Comment (Reserve-Resource): USGS BULLETIN 1090, P. 54-80
Comment (Production): MORE THAN 50% OF THIS PRODUCTION CAME FROM MAMIE MINE
Comment (Deposit): ORE BODIES ARE CONTORTED LENSES OF MAGNETITE CONTAINING DISSEMINATED CHALCOPYRITE AND CALCITE, GARNET AND EPIDOTE GANGUE. AREAS THAT WERE RICHER IN CHALCOPYRITE GRADED TOWARDS MASSIVE. THESE BODIES, WHICH ARE CONTACT METASOMATIC REPLACEMENTS OF LIMESTONE LENSES WITHIN VOLCANICLASTIC STRATA ARE UP TO 600 FEET LONG, 550 FEET WIDE AND 150 FEET DEEP, BUT MOST ARE A GOOD DEAL SMALLER E.G. 50-100 FEET LONG, 10-40 FEET WIDE
