Wagner

The Wagner 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 (Reference): Primary Reference = Jansons and others, 1984

Comment (Workings): Workings / Exploration = Workings visible in the 1980s consisted of one caved adit (Jansons and others, 1984), originally reported to be 285 feet long (Cobb, 1979: OFR 79-973). A selected grab sample from the dump contained 39 ppm Cu (Jansons and others, 1984).

Comment (Geology): Geologic Description = The country rocks at this prospect are mafic volcanic rocks and sedimentary rocks of the Tertiary Orca Group (Nelson and others, 1985). The deposit consists of quartz-chalcopyrite lenses in a shear zone in graywacke (Cobb, 1979: OFR 79-973). Workings visible in the 1980s consisted of one caved adit (Jansons and others, 1984), originally reported to be 285 feet long (Cobb, 1979: OFR 79-973). A selected grab sample from the dump contained 39 ppm Cu (Jansons and others, 1984).

Comment (Deposit): Other Comments = Nelson and others (1985) interpret the country rocks as accreted ocean crust. Crowe and others (1992; 1993) and Sainsbury (1993) discuss the genesis of the volcanogenic massive sulfide deposits in this area. Chugach Alaska Corporation, Anchorage, Alaska has control of these lands. This site is shown as a 'mine' on the map. Since there was no production from this deposit it is designated herein as a 'prospect.'

Comment (Deposit): Model Name = Cyprus massive sulfide (Cox and Singer, 1986; model 24a)

Comment (Geology): Age = Probably Tertiary based on the age of the host rocks.

Comment (Exploration): Status = Inactive
