The Comstock Mine is a iron mine located in Iron county, Utah at an elevation of 6,804 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 (Geology): THE COMSTOCK ORE BODY IS MOSTLY TABULAR IN SHAPE BUT CERTAIN PORTIONS OF IT ARE IRREGULAR. FISSURE TYPE DEPOSITS HAVE NOT BEEN FOUND IN THE COMSTOCK MINE YET, BUT IT IS SUSPECTED THAT THEY ARE PRESENT IN VERY MINOR AMOUNTS. THE DIP AND STRIKE OF THE OREBODY AT THE COMSTOCK MINE ARE ESTIMATES FROM THE LITERATURE AND FROM WHAT WAS OBSERVED IN A VISIT TO THE MINE.

Comment (Geology): THE ORE IS KNOWN TO CONTAIN VERY MINOR AMOUNTS OF HEMATITE, WHICH IS MIXED WITH MAGNETITE. HOWEVER, THE PERCENT OF HEMATITE IS UNKNOWN.

Comment (Deposit): MINING PROPERTY PURCHASED BY GENEVA STEEL IN 1990. THIS PROPERTY NOW COMBINED AS ONE PROPERTY WITH MT. LION. DEPOSIT CALLED COMSTOCK/MT LION UNDER PROPERTY FILE SEQ. NO. 0490210041.
