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 (Geology): GENERAL SIZE OF ORE BODY IS SMALL. THE MINERALIZED ZONE CAN BE TRACED FOR AT LEAST 1,200 METERS ALONG STRIKE. ORIGIN OF ORE BODY ALSO SHEAR ZONE. EXCAVATION DEPTH- 360 (PLANNED) (MINERALIZED ZONE) OTHER TYPE OF WALL ROCK ALTERATION IS OXIDATION. STRIKE AND DIP- NE: 30S. SHALE IS CARBONACEOUS CALCAREOUS. CLAY IS DERIVED FROM ANDESITE SILL.

Comment (Economic Factors): ORE IS SHIPPED ABOUT 24 KM BY TRUCK TO PINSON MILL.

Comment (Production): MORE DETAILED PRODUCTION AND RESERVE DATA IS INCLUDED IN THE PINSON MAS DEPOSIT FILE #0320130220.

Comment (Economic Factors): PREBLE PIT IS CLOSED: MATERIAL IS BEING MINED AT KRAMER HILL (A SATELLITE PIT) AND TRUCKED TO PREBLE FOR PROCESSING. APPROXIMATELY 50 ACRES HAVE BEEN RECLAIMED AT THE PREBLE FACILITY.
