The Montana is a iron 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 (Exploration): Status = Inactive
Comment (Reference): Primary Reference = Berg and Cobb, 1967
Comment (Workings): Workings / Exploration = Surface sampling is all that has been done here (Berg and Cobb, 1967). The highest tenor reported is 41.2% Fe.
Comment (Geology): Geologic Description = Bog iron is currently forming a deposit about 50 feet in diameter, up to 8 feet thick, composed of limonite and probably other hydrous iron minerals (Berg and Cobb, 1967). The highest tenor reported is 41.2% Fe.
Comment (Deposit): Other Comments = This area is not large enough to be of economic interest; however, the area has not been prospected for similar, perhaps larger, deposits which may be present. This occurrence may be no more significant than the numerous unreported occurrences of this type occur throughout Alaska.
Comment (Deposit): Model Name = Cox and Singer (1986) and Bliss (1992) do not include an ore deposit model for this type of occurrence.
Comment (Commodity): Ore Material = other hydrous iron minerals.
Comment (Geology): Age = Recent.
