The Culverwell Adit is a copper, tungsten, gold, and silver mine located in Lincoln county, Nevada at an elevation of 5,850 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 (Location): INFO FROM LAND.ST :1972
Comment (Development): NO ACTIVITY AT TIME OF EXAMINATION IN 1983, BUT TRENCHING WAS PROBABLY DONE IN PAST 5 YEARS OR SO.
Comment (Deposit): THE SHAFT IS INCLINED ALONG AN IRON-STAINED, SILICIFIED, GOSSAN REPLACEMENT ZONE. MINERALIZED DUMP ROCK IS RED-BLACK, VERY DENSE AND COMPOSED ALMOST WHOLLY OF MAGNETITE. MAGNETITE ALSO OCCURS IN CALCITE-VEINED TACTITE AND AS REPLACEMENT PODS IN THE LIMESTONE. LIMESTONE WASTE ROCK SHOWS VARIOUS TYPES OF ALTERATION INCLUDING SILICATION, MARBELIZATION, AND REPLACEMENT OR STAINING BY IRON-OXIDES (GOSSAN). SAMPLE 1707 IS OF REPLACED LIMESTONE COLLECTED FROM BULLDOZER TRENCH IN DRAINAGE BELOW ADIT. THE ROCK IS BANDED, VERY DENSE, AND CONTAINS LENSES AND VEINS OF CALCITE AND OXIDIZED PODS AND CRYSTALS OF MAGNETITE, COPPER OXIDES, PYRITE, AND CHALCOPYRITE. THE SAMPLE WAS LAMPED AND ONLY TWO VERY FINE SPECKS OF SCHEELITE WERE OBSERVED. ROCKS EXPOSED IN BULLDOZED TRENCH CONSISTS OF A SEQUENCE OF WHITE MEDIUM-COARSELY CRYSTALLINE MARBLE, EPIDOTIZED MONZONITE-DIORITE INTRUSIVE ROCK AND BANDED, LIGHT AND DARK GREEN TACTITE. CONTACT OF INTRUSIVE WITH LIMESTONE IS NOT WELL-EXPOSED, BUT ORIENTATION
Comment (Deposit): IS PROBABLY NE-SW. WEATHERED, CHLORITICALLY ALTERED INTRUSIVE OUTCROPS AT BOTTOM OF TRENCH JUST NW OF ADIT. THE ROCK HAS FE-STAINED FRACTURES AND CARRIES A SMALL AMOUNT OF OXIDIZED PYRITE. SILICATED
Comment (Workings): S30E-TRENDING ADIT RECENTLY DEMOLISHED BY TRENCHING AND SCRAPING IN DRAINAGE AREA. REMAINS OF TRACK NEAR PORTAL. PROSPECT ABOVE ADIT IS A CAVED SHAFT INCLINED ABOUT 40 NE.
