NBMG Sample Site 3948

The NBMG Sample Site 3948 is a silver, copper, molybdenum, and tungsten mine located in Churchill county, Nevada at an elevation of 6,161 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.

Land Status

Land ownership: BLM Administrative Area
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 (Development): NO ACTIVITY AT TIME OF EXAMINATION IN OCT. 1986, BUT AREA WAS STAKED AS A MO-CU PROSPECT IN 1970 AND 2 SHALLOW ROTARY DRILL HOLES PUT DOWN IN AREA OF FE-STAINED DUMP AND IN LAPLATA CANYON WEST OF THE DUMP. DRILL HOLES INTERSECTED WEAK SKARN MINERALIZATION WITH MINOR MOLYBDENITE, AND CHALCOPYRITE. CLAIMS NOW INACTIVE.

Comment (Deposit): SKARN QUARTZ VEIN, SERICITIZATION, KAOLINIZATION WITH SULFIDES AND TUNGSTEN MINERALIZATION. SHALE & SILTSTONE IN CONTACT WITH GRANITE BOTH CUT BY VEINS AND PODS OF WHITE QUARTZ LOCALLY CONTAINING SULFIDES. GRANITIC MATERIAL FROM THE LARGE DUMP JUST EAST OF LAPLATA CANYON IS SERICITIZED AND FE-STAINED. PODS OF GARNET-EPIDOTE-CALCITE SKARN HAVE FORMED IN PLACES ALONG THE GRANITE-SEDIMENTARY ROCK CONTACT.

Comment (Workings): PROSPECT

Comment (Deposit): Discovery Year: 1860'S

Comment (Location): ON EAST SIDE OF LAPLATA CANYON ABOUT 0.7 MILE ABOVE LAPLATA SITE ; INFO FROM LAND.ST :(1972)
