The Beltz 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): Geologic Description = Bedrock at the Beltz prospect is mainly altered, Jurassic-Cretaceous andesitic tuff and greenstone cut by mafic and felsic dikes. Quartz and calcite veins carry disseminated chalcopyrite. The rocks are iron- and copper-stained (Harrington, 1919).
Comment (Exploration): Status = Inactive
Comment (Commodity): Gangue = Iron oxides
Comment (Deposit): Model Name = Chalcopyrite-quartz-calcite veins in andesite, tuff, and greenstone.
Comment (Workings): Workings / Exploration = The deposit has been prospected by ten or more small pits. In 1917, the pits were badly caved and filled with slope talus (Harrington, 1919). The site was visited by Herreid (1965), who reports a trench 80 feet long and 3 to 5 feet deep.
Comment (Geology): Age = Jurassic-Cretaceous or younger.
Comment (Reference): Primary Reference = Harrington, 1919
