The Cinch Claim is a tungsten mine located in Lincoln county, Nevada at an elevation of 6,601 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): BAST FLANK OF SCHELL CREEK RANGE REAR PATTERSON PASS ON SMALL HILL

Comment (Production): TOTAL PRODUCTION 750 UNITS WORTH $19,000

Comment (Development): SAMPLING, MAPPING AND DRILLING IN AREA IN 1981 BY UNION CARBIDE. DRILLING WAS NE OF MAIN WORKINGS ON LOW HILL.

Comment (Geology): SCHEELITE DISEMINATED WITHIN QUARTZ VEINS, DEPOSIT OCCURS ON UPPER PLATE OF PROBABLE THRUST FAULT, SEVERAL EAST-WEST FRACTURES CROSS-CUT THE BRECCIATED ZONE. POSSIBLE INTRUSIVE AT DEPTH OF 450 FT. BRECCIA ZONE CONSISTS OF SILICEOUS LIMESTONE FRAGMENTS CEMENTED IN A SILICA-IRON-OXIDE MATRIX. THRUST (?) FAULT IS A POSSIBLE DECOLLEMENT ALONG WHICH CAMBRIAN SEDIMENTARY ROCKS WORE EMPLACED OVER TERTTARY VOLCANIC RX.

Comment (Deposit): DEPOSITS OCCUR IN BRECCIATED ZONES AND VEINS. SCHEELITE IS EXTREMELY FINE-GRAINED AND NEARLY ALL OF IT IS IN THE FRAGMENTS OF VEIN QUARTZ. BECAUSE OF THE FINE GRAINED NATURE OF THE SCHEELITE, WHOLE PIECES OF QUARTZ FLUORESCE IN UV LIGHT EVEN THOUGH TOTAL WO3 CONTENT IS NOT HIGH. BRECCIA ZONE CONTAINS LARGE PODS OF COARSE CRYSTALLINE WHITE CALCITE 2-3 FT ACROSS. SEVERAL SMALL E-W FRACTURES CUT THE ZONE AT AN ANGLE. W OCCURS IN THE QUARTZ GANGUE AS WELL AS IN THE GANGUE MATERIAL.

Comment (Workings): SEVERAL TRENCHES, ADITS, STOPES, OLD ORE-CHUTES AND BUILDINGS ON SITE , PITS, OPEN CUTS
