Big Deal Claims

The Big Deal Claims is a mercury mine located in Humboldt county, Nevada at an elevation of 5,249 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.

Land Status

Land ownership: BLM Administrative Area
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): NW FLANK OF HOT SPRINGS PEAK

Comment (Deposit): IN 1970, THE BIG DEAL CONSISTED OF 3 CONTIGUOUS UNPATENTED CLAIMS. DEVELOPMENT CONSISTS OF A 20-FT. SHAFT AND SHORT ADIT EACH EXPOSING NARROW MINERALIZED FAULT ZONES. ANY POTENTIAL IS FOR SMALL, HIGH-GRADE MERCURY ORE INSUFFICIENT TO SUPPORT A LARGE MINING OPERATION. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV

Comment (Development): 3 CONTIGUOUS UNPATENTED CLAIMS

Comment (Workings): SHORT ADIT, 20-FT SHAFT

Comment (Geology): GEOL.COM: CINNABAR IS DISSEMINATED IN NARROW CALCITE AND QUARTZ LENSES PARALLEL TO BEDDING. MINERALIZATION DOES NOT EXTEND INTO THE WALLROCK BEYOND BEDDING PLANT FAULTS. THE DEVELOPED MINERALIZED STRUCTURE IS 1 1/2 FT. WIDE AT THE BOTTOM OF THE SHAFT AND CONSIST OF A CENTRAL SILICIFIED ZONE BOUNDED BY 2 FAULTS WITH CINNABAR ALONG EACH FAULT AND WITHIN THE SILICEOUS MATERIAL. THE ADIT STRUCTURE PARALLELS THE SHAFT STRUCTURE 130 FT. TO THE SE. A N10E MINERALIZED FAULT NEAR THE ADIT MAY INTERSECT THE ADIT STRUCTURE TO THE SW PROVIDING A POTENTIAL LOCUS FOR A POD OF HIGH-GRADE CINNABAR AT THE INTERSECTION.
