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 (Deposit): DEPTH OF COVER: 0 TO DEPTH OF MINING. DEPTH OF UNCONSOLIDATED COVER: RANGES FROM 0 - MANY METERS.

Comment (Location): POINT OF REFERENCE IS CENTROID; 100

Comment (Geology): FORMATION NAME IS CLIMAX STOCK. THREE SUCCESSIVE STAGES OR EPISODES OF MINERALIZATION RELATED TO EVOLUTION OF CLIMAX STOCK DURING OLIGOCENE - ENDING ABOUT 30 MY BEFORE PRESENT. MAJOR POST-ORE GEOLOGIC EVENT WAS THE MAJOR REACTIVATION OF PRE-ORE MOUSQUITO FAULT. AGE OF POST-ORE GEOLOGIC EVENT IS LTERT.

Comment (Production): PRODUCTION CAPACITY: 900 MT/Y IN 1983. FUTURE FOR TUNGSTEN PRODUCTION ENTIRELY DEPENDENT ON MARKET CONDITIONS OF MAJOR PRODUCT - MOS2. MAJOR SOURCE OF UNITED STATES TUNGSTEN PRODUCTION. W03 IS BY-PRODUCT. PRODUCTION CONTINUING AT APPROXIMATELY THE SAME RATE.

Comment (Development): NATURE OF DISCOVERY WAS CONVENTIONAL PROSPECTING. PRODUCT UPGRADED BEFORE EXPORT: CONCENTRATES. CLOSED FROM MID-1982 TO MARCH 1984; THEN REOPENED. NON-GEOLOGIC CONSTRAINTS ON DEVELOPMENT OR EXPANSION IN 1-5 YEARS DUE TO THE MARKET. THERE IS ACTIVE DEVELOPMENT IN THE MINE. PREDICTION OF 20 YEARS FUTURE OPERATION.

Comment (Commodity): MOLYBDENUM IS PRIMARY PRODUCT. TUNGSTEN IS MAJOR BY-PRODUCT. HUEBNERITE, CASSITERITE, PYRITE, AND MONZANITE ARE BY-PRODUCTS.
