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.
Elevation: 9,449 Feet (2,880 Meters)
Primary Mineral: Silver, Zinc, Lead
Lat, Long: 40.61639, -111.54028

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.

Land ownership: Private
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.

Comment (Deposit): BALMOUNT SHAFT AREA, OTHERWISE KNOWN AS THE SILVER HILL SHAFT AREA, PRODUCED 811,382 TONS OF ORE GRADING .019 OZ/TON AU, 7.50 OZ/TON AG, 11.33% PB, 6.01% ZN, AND .19% CU. SOME OF THIS PRODUCTION MAY HAVE COME FROM THE BALMOUNT-ATLANTA TUNNEL. ; INFO.SRC : 1 PUB LIT
Comment (Location): INFO FROM LAND.ST :1983
Comment (Development): PROSPECTS ABANDONED IN 1903; HOWEVER, MAY HAVE BEEN ACTIVE DURING THE LATER DEVELOPMENT OF THE SILVER HILL AREA
Comment (Deposit): SEVERAL EAST-WEST STRIKING FISSURES ARE EXPOSED IN THE TUNNEL. ONE FISSURE, LOCATED 700 FT FROM THE PORTAL, SHOWED GOOD STAINING AND SOME MINERALIZATION. AS OF 1903 NO ORE HAD BEEN FOUND. DEVELOPMENT MAY HAVE BEEN DONE HERE DURING THE ACTIVITY AT THE ADJACENT SILVER HILL SHAFT. PRESUMABLY BOTH VEIN AND REPLACEMENT TYPES OF MINERALIZATION ARE PRESENT, REPLACEMENTS BEING LOCATED IN THE THAYNES FORMATION
Comment (Workings): LOCATION GIVEN FOR CARD IS THE PORTAL OF THE BALMOUNT-ATLANTA TUNNEL. THIS TUNNEL WAS BLOCKED 1200 FT FROM PORTAL IN 1903. TOTAL LENGTH AT THAT TIME IS UNKNOWN. ONE OTHER ADIT, OF UNKNOWN LENGTH, AND TWO PROSPECT PITS ARE LOCATED NEAR THE BALMOUNT-ATLANTA TUNNEL. MUCH LENGTHENING OF THESE ADITS MAY HAVE TAKEN PLACE DURING THE DEVELOPMENT WORK AT THE BALMOUNT SHAFT, OTHERWISE KNOWN AS THE SILVER HILL SHAFT.
Comment (Geology): WORKINGS EXPLORE A NORTHEAST STRIKING SPLAY OF THE CRESCENT FAULT ZONE WHICH TRANSECTS THE ANKAREH FORMATION AT THE SURFACE
Comment (Deposit): Discovery Year: LATE 1800'S
