NBMG Sample Location 1759

The NBMG Sample Location 1759 is a gold and silver mine located in Lincoln county, Nevada at an elevation of 5,899 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.

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 (Deposit): BETWEEN FRAGMENTS. VEIN WAS PROBABLY EMPLACED ALONG A FAULT WHICH DOWNDROPS FE-STAINED BLEACHED VOLCANICS AGAINST CAMBRIAN LIMESTONE, AS VOLCANICS ARE EXPOSED ON WEST SIDE OF VEIN IN ONE PORTION OF T

Comment (Workings): AT LEAST 3 SHAFTS WITH CONNECTING DRIFTS OR STOPES ALONG VEIN STRUCTURE. AT LEAST 4 DRILL HOLES AND PADS LOCATED NEAR OR ADJACENT TO WORKINGS (NORTHERN WORKINGS). 2 INCLINED SHAFTS AND A CONNECTING STOPE AT SOUTHERN WORKINGS.

Comment (Deposit): NORTHERN SHAFT BEGINS IN ALTERED RHYOLITE. MOST OF DUMP CONSISTS OF WHITE ALTERED RHYOLITE WHICH SHOWS OXIDIZED CLOTS AND GHOSTS AFTER PYRITE AND PINK, RED AND ORANGE IRON OXIDE BANDS OR OXIDATION RINGS. A SMALL AMOUNT OF GREY LIMESTONE WITH CALCITE VEINING WAS ALSO FOUND ON THEDUMP. DRILL CUTTINGS ARE ALSO COMPOSED OF GREY LIMESTONE. SOUTHERN WORKINGS ARE A COMBINATION OF 2 INCLINED SHAFTS AND A CONNECTING STOPE. THESE WORKINGS PROVIDE BETTER EXPOSURE OF THE MINERALIZED VEIN STRUCTURE. A QUARTZ-CEMENTED BRECCIA VEIN CUTS GREY LAMINATED LIMESTONES, MEDIUM-BEDDED (1-2FT) CONTAINING GIRVANELLA ALGAL PODS AND STRIKING N10E, DIP 35 SE. THE EXPOSED VEIN IS ABOUT 3 FT WIDE AT MAIN WORKING BUT APPEARS TO NARROW TO THE NORTH TO 1-2 FT WIDE. THE VEIN IS COMPOSED MAINLY OF QUARTZ AND QUARTZ-CEMENTED LIMESTONE BRECCIA. LIMESTONE FRAGMENTS CONTAINED IN THE VEIN ARE SILICIFIED, FE-STAINED AND RECEMENTED BY WHITE VITREOUS AND GREY COMB AND DRUSY EPITHERMAL QUARTZ. EUHEDRAL QUARTZ-FILLED MGS OCCUR

Comment (Development): NO ACTIVITY AT TIME OF EXAMINATION IN 1983, BUT PROBABLY DRILLED WITHIN PAST 3-5 YEARS.
