Mogul (Banta and Cameron)

The Mogul (Banta and Cameron) is a copper and zinc 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 (Reserve-Resource): Reserves = Inferred reserves of 400 tons @ 0.25% Cu (Jansons and others, 1984).

Comment (Workings): Workings / Exploration = The prospect was explored by a 13-foot shaft and several surface excavations. Six chip samples contained 620 ppm to 0.37% Cu (Jansons and others, 1984).

Comment (Exploration): Status = Inactive

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

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

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.

Comment (Geology): Geologic Description = The country rocks at these prospects are mafic volcanic rocks and sedimentary rocks of the Tertiary Orca Group (Nelson and others, 1985). The deposit consists of irregular masses of chalcopyrite, pyrite, pyrrhotite, and sphalerite in a shear zone up to four feet wide in mafic volcanic rocks (Jansons and others, 1984).? the prospect was explored by a 13-foot shaft and several surface excavations. Six chip samples contained 620 ppm to 0.37% Cu (Jansons and others, 1984).
