The Culverwell Prospect is a gold and silver mine located in Lincoln county, Nevada.
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.

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 (Production): 16 CARLOADS OF AU ORE
Comment (Development): NO ACTIVITY AT TIME OF EXAMINATION IN 1983. EXPLORED BY KENNECOTT AND HOMESTAKE IN 1960'S, WESTERN VENTURES AND CORDILLERAN EXPLORATION (1969-1971).
Comment (Geology): FLAT QUARTZ VEIN, PROBABLY AN EXTENSION OF THE PENNSYLVANIAN VEIN
Comment (Location): AREA UNSURVEYED ; INFO FROM LAND.ST :(1972)
Comment (Commodity): ORE MINERALS NOT GIVEN IN THE LITERATURE
Comment (Deposit): LIMESTONE IS ALTERED, EITHER SILICATED TO LIGHT GREEN OR DENSE DARK GREEN-BROWN TACTITE, OR BLEACHED AND RECRYSTALLIZED TO A WHITE CRYSTALLINE MARBLE. THE ROCKS ARE CUT BY IRREGULAR IRON-STAINED VEINS. PROSPECT APPEARS TO FOLLOW A N-S FAULT OR QUARTZ VEIN SYSTEM WHICH IS THOUGHT TO BE A SOUTHERN EXTENSION OF THE PENNSYLVANIA VEIN. SILICATION INDICATES THAT ROCKS ARE LOCALLY INTRUDED BY DIKES OR OTHER INTRUSIVE BODIES AS SHOWN ON USGS MAP AND COUNTY REPORT. HOWEVER, NO INTRUSIVE ROCKS WERE OBSERVED IN THE IMMEDIATE AREA. SAMPLE 1706 CONSISTS OF QUARTZ VEIN AND QUARTZ-CEMENTED SEDIMENTARY BRECCIA WITH CLOTS AND CRYSTALS OF OXIDIZED PYRITE, CHALCOPYRITE AND SURFACE COATINGS OF CU-FE-MN OXIDES. VEIN MATERIAL HAS SMALL VUGS LINED WITH MN-COATED QUARTZ CRYSTALS AND RADIATING MALACHITE. THIN OPEN-CENTERED VEINLETS CUT MORE MASSIVE SUGARY VEIN MATERIAL. SAMPLED VEIN IS DARK GREY (ESPECIALLY IN AREAS CONTAINING CRYSTALS OF UNOXIDIZED PYRITE) INDICATING A HIGH PERCENTAGE OF DISPERSED SULFIDES
Comment (Deposit): (AG MINERALS ?)
Comment (Workings): COULD BE MINED BY OPEN PIT
