The NBMG Sample Location 786 is a copper and silver mine located in Lincoln county, Nevada at an elevation of 5,951 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.

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.

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 (Deposit): WORKINGS ARE LOCATED ON A SHEAR ZONE IN A CONTINUOUS LINE EXTENDING FOR ABOUT 100 FT ALONG STRIKE. ROCKS IN THE ZONE ARE NOTABLY FRACTURED AND IN PLACES COMPLETELY ALTERED TO CLAYS (ARGILLIZED). EPIDOTE AND CU AND FE OXIDES ARE ABUNDANT IN THE ZONE AS COATINGS ON FRACTURE SURFACES. IRREGULAR LENSES OF HIGHLY FE-STAINED, DENSE, SILICIFIED MATERIAL WITHIN THE ZONE IS COMPOSED OF PODS OF MAGNETITE, PSILOMELANE, SPECULARITE, AND ABUNDANT CU MINERALS, MAINLY MALACHITE AND CHRYSOCOLLA WITH MINOR AZURITE. A SAMPLE OF THIS TYPE OF MINERALIZED ROCK WAS COLLECTED FROM THE DUMP. YELLOW AND GREEN OXIDES CHARACTERIZE THIS ZONE AND MAY BE AMIXTURE OF CU MINERALS, FE PO4, EPIDOTE, OR OTHER ALTERATION PRODUCTS. ADJACENT TO THE FRACTURED, MINERALIZED ZONE, THE INTRUSIVE IS BLEACHED, SLIGHTLY SILICIFIED, AND EPIDOTIZED OR CHLORITIZED ALONG FRACTURES. SOME OF THE INTRUSIVE DISPLAYS CROSS-CUTTING FE AND MAGNETITE VEINLETS LESS THAN 1 INCH IN WIDTH.
Comment (Workings): 2 SHAFTS AND CONNECTING SHALLOW STOPES. ONE SHAFT IS SHALLOW AND CAVED, OTHER SHAFT IS ABOUT 15-20 FT DEEP AND INCLINED TO THE SE
Comment (Geology): SOME PINK RHYOLITE FOUND AS FLOAT NEAR WORKINGS
Comment (Development): NO ACTIVITY AT TIME OF EXAMINATION IN 1983, BUT AREA IS CURRENTLY STAKED
Comment (Location): INFO FROM LAND.ST :1972
