The Cumberland Mine is a lead, zinc, and silver mine located in Humboldt county, Nevada at an elevation of 6,037 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 HERE, BUT EXXON CO. HAS RECENTLY DRILLED ON CLAIMS TO THE SE ABOUT 1.2 KM.
Comment (Deposit): PYRITE, GALENA AND SPHALERITE OCCUR AS MASSIVE REPLACEMENTS OF WALLROCK AND IN WHITE MASSIVE TO DRUSY QUARTZ. NO OBVIOUS VEINS ARE NOTED; THE QUARTZ APPARENTLY OCCURS AS PODS. THE WALLROCKS AWAY FROM THE MINERALIZED ZONE ARE INTERBEDED GRAY SHALE AND LIMESTONE. IN THE OPEN PIT, THE ROCKS ARE HARD DENSE SILICIFIED HORNFELS WITH A HIGH SULFIDE MINERAL CONTENT. ONE PIECE OF ORE, INCLUDED IN SAMPLE 2355 IS ENTIRELY SOLID GALENA AND SPHALERITE. PYRITE OCCURS AS STREAKS AND IRREGULAR PATCHES IN DENSE SILICA-RICH ROCK. WHITE QUARTZ VEIN MATTER CONTAINS SCATTERED GALENA AND PYRRHOTITE. A DIKE OF ALTERED GRANODIORITE PORPHYRY WAS NOTED IN THE PORTAL OF AN ADIT ABOUT 400 M NORTH OF THE SAMPLED OPEN PIT. NO OTHER IGNEOUS ROCKS WERE NOTED. THE SILICIFIED AND SULFIDE-RICH ROCKS AT THIS PROPERTY RESEMBLE THOSE AT THE HILLSIDE OR ADELAIDE MINES, EXCEPT THAT THERE ARE NO OBVIOUS COPPER MINERALS HERE.
Comment (Workings): NUMEROUS ADITS AND PITS; A SMALL OPEN PIT
