The Half Moon Mine is a lead and silver mine located in Lincoln county, Nevada at an elevation of 6,719 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.
Elevation: 6,719 Feet (2,048 Meters)

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.
Half Moon Mine MRDS details
Primary: Half Moon Mine
Secondary: NBMG Sample Site 1433.
District: Pioche District District
Land ownership: Private
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.

Comment (Workings): 2 MAJOR ADITS COMPRISED THE WORKINGS IN 1932. ADIT WAS CAVED AND BOARDED UP IN 1983, WITH PERIPHERAL LESSER WORKINGS. OLDER WORKINGS OBLITERATED BY NEW DRILL ROADS BEING BUILT IN 1983.
Comment (Geology): ORE IS IN FLAT LYING VEIN, APPROX 1 FOOT THICK, SOME PLACES UP TO 2 FEET. MAIN SULFIDE ORE IS GALENA, IN BLEBS AND VEINLETS, ALSO SOME PYRITE OXIDIZED TO LIMONITE, IN A MILKY WHITE QUARTZ GANGUE. VEIN IS IN OFFSET SEGMENTS, AND OCCURS AT THE BASE OF A 3 FT. LIMESTONE LARGELY REPLACED BY MANGANESE AND IRON OXIDE ORE.
Comment (Deposit): WORKINGS FOLLOW FISSURE-FILLING QUARTZ VEIN PARALLEL TO BEDDING PLANE BETWEEN SHALE AND LIMESTONE. ORE CONSISTS OF CRYSTALLINE PODS, BLEBS, AND STRINGERS OF ARGENTIFEROUS GALENA AND SPHALERITE ALONG WITH SECONDARY ANGLESITE ?, CERUSSITE AND MALACHITE IN QUARTZ VEIN STAINED WITH HEMATITE AND MN OXIDE. SULFIDES OCCUR BOTH FRESH AND OXIDIZED. QUARTZ VEIN HAS BEEN SHEARED AND CRUSHED BY LATER MOVEMENT. VEIN CHANGES DIP ABRUPTLY TO THE SOUTH, STEEPENING TO 60-70S.
