Korn Kob Mine

The Korn Kob Mine is a copper, tungsten, and molybdenum mine located in Pima county, Arizona at an elevation of 3,461 feet.

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.

Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments

Comment (Commodity): Molybdenite Is Near And Replacing Garnet, Powellite Is Reaction Rim Around Molybdenite.

Comment (Development): Developed Around 1910

Comment (Workings): 130 Ft Shaft And Tunnels With 3900 Ft Of Workings On 2 Levels

Comment (Deposit): Molybdenite disseminated in skarn near garnet in polymetamorphosed Abrigo and Martin Formations probably mineralized by Laramide (65-70 m.y.-old) Leatherwood quartz diorite. Later fracturing localized secondary copper minerals. (Wilt et al, 1984)
