The Delamar Zinc is a zinc and lead mine located in Lincoln county, Nevada at an elevation of 6,401 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: 6,401 Feet (1,951 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.
Delamar Zinc MRDS details
Primary: Delamar Zinc
Secondary: North Star Claims
Secondary: NBMG Sample Site 1745
District: Delamar (Ferguson) 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): INCLINED SHAFT, 3 SHAFTS: MAIN SHAFT FAIRLY DEEP AND MAY BE INCLINED AT DEPTH. SOME DRILLING WAS DONE ON THE OTHER SIDE OF THE RIDGE SOUTH OF THESE WORKINGS PROBABLY SEVERAL YEARS AGO., 3 SHAFTS: MAIN SHAFT FAIRLY DEEP AND MAY BE INCLINED AT DEPTH. SOME DRILLING WAS DONE ON THE OTHER SIDE OF THE RIDGE SOUTH OF THESE WORKINGS PROBABLY SEVERAL YEARS AGO.
Comment (Geology): ORE IN LIMESTONE NEAR VOLCANIC CONTACT, CONTAINING 15-30% ZN, 6% PB.
Comment (Deposit): SHAFTS SUNK ON A NE-STRIKING FAULT IN THE CHISHOLM SHALE AND ON A NW-STRIKING FAULT BETWEEN THE HIGHLAND PEAK LIMESTONE AND CHISHOLM SHALE. PRESENCE OF GOSSAN BRECCIA SUPPORTS A FAULT-RELATED ORIGIN. SHAFT NO. 1 (WESTERNMOST) EXPOSES A 2 FT WIDE REPLACEMENT VEIN WHICH PARALLELS THE BEDDING OF THE HOST LIMESTONE. THE VEIN STRIKES N40E, DIPS 60SE AND HAS A SHARP CONTACT WITH ENCLOSING HOST ROCK, WHICH APPEARS LITTLE ALTERED. VEIN IS COMPLETELY OXIDIZED, AND CONSISTS OF LIMONITIC AND MN-RICH GOSSAN WITH SOME CALCITE AND SILICA VEINING AND VUG FILLINGS. CALCITE (AND PROBABLY SOME SMITHSONITE) ALSO CEMENTS GOSSAN BRECCIA FOUND ON THE DUMP. THE GOSSAN IS QUITE DENSE AND MAY CONTAIN PB OR ZN MINERALS, BUT NO UNOXIDIZED MINERALS WERE OBSERVED. SHAFT NO. 2, (SOUTHERNMOST): UPPER SHAFT EXPLORES SIMILAR REPLACEMENT VEIN 5-6 FT WIDE STRIKING N30E, DIP 80SE. THE VEIN POSSIBLY PARALLELS THE BEDDING OR CROSSCUTS THE BEDDING AT A LOW ANGLE. THE GOSSAN "VEIN" IS NOT AS PURE OR HIGHGRADE AS THAT
Comment (Deposit): OBSERVED IN NO. 1. INSTEAD, IT IS SPOTTY, PINCHES OUT AND CONTAINS LIMESTONE LENSES ALONG FRACTURES PARALLEL TO BEDDING. SHAFT NO. 3 (NORTHERNMOST): LOWER SHAFT IS INCLINED ALONG STRIKE OF N10-20E (POORLY EXPOSED) TRENDING GOSSAN REPLACEMENT VEIN WHICH IS PROBABLY A CONTINUATION OF THE VEIN OBSERVED IN NO. 2. ADIT (OR INCLINE) LOCATED BELOW AND INTERSECTING THE SHAFT IS CAVED. DUMP CONSISTS OF LIMESTONE WASTE ROCK AND LIMONITIC MN-GOSSAN WHICH IN GENERAL IS LIGHT-WEIGHT, PUNKY, AND IN PART SILICEOUS. SAMPLE 1745 WAS TAKEN FROM THIS SHAFT.
Comment (Development): NORTH STAR CLAIMS LOCATED 1974 BY 2 PERSONS FROM CALIENTE (NAMES ILLEGIBLE). NO ACTIVITY AT TIME OF EXAMINATION IN 1983
