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 (Economic Factors): FISSURE TYPE OF ORE DEPOSITS ARE NOT FOUND BUT IN VERY MINOR AMOUNTS IN THE MOUNTAIN LION MINE. THE DIP AND STRIKE OF THE OREBODY AT THE MOUNTAIN LION MINE ARE ESTIMATES FROM THE LITERATURE AND FROM WHAT WAS OBSERVED IN A VISIT TO THE MINE.

Comment (Reserve-Resource): UPDATED PEFR REPORT MARCH 1991

Comment (Geology): FISSURE TYPE OF ORE DEPOSITS ARE NOT FOUND BUT IN VERY MINOR AMOUNTS IN THE MOUNTAIN LION MINE. THE DIP AND STRIKE OF THE OREBODY AT THE MOUNTAIN LION MINE ARE ESTIMATES FROM THE LITERATURE AND FROM WHAT WAS OBSERVED IN A VISIT TO THE MINE.

Comment (Production): SINCE THERE IS NO BENEFICIATION INVOLVED, THE YIELD DATA SET SHOWS THE CRUSHED ORE GRADE WITH 100-PERCENT RECOVERY.

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

Comment (Location): THE COORDINATES OF THE MILL (CRUSHING PLANT) ARE APPROXIMATE

Comment (Deposit): PROPERTY UPDATED FEB 1991. COMSTOCK PROPERTY (SEQ NO. 0490210007) COMBINED WITH MT LION PROPERTY. BOTH MINES ARE NOW UNDER SEQ NO. 0490210041.

Comment (Ownership): THE ORE IS KNOWN TO CONTAIN MINOR AMOUNTS OF HEMATITE, WHICH IS MIXED WITH MAGNETITE; HOWEVER, THE PERCENT OF HEMATITE IS UNKNOWN. GENEVA STEEL (FORMERLY KNOWN AS BASIC MFG & TECHNOLOGIES OF UTAH) PURCHASED THE MOUNTAIN LION PROPERTY FROM USX CORP IN 1987. IN 1990, GENEVA STEEL PURCHASED THE ADJACENT PROPERTY, COMSTOCK, (SEE MAS DATA BASE SEQ NO 0490210007). THE COMSTOCK AND MOUNTAIN LION MINES ARE NOW CONSIDERED AS ONE MINE, THE COMSTOCK/MT LION.
