The Kolchek is a gold and tungsten mine located in White Pine county, Nevada.

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: National Forest
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): 1:24000 QUADRANGLE MAP IS A 1981 EDITION

Comment (Production): 32 TONS OF ORE CONTAINING 3.15 % W03 WAS SHIPPED FROM THE MINE IN 1953.

Comment (Development): THE KOLCHEK MINE WAS FIRST OPERATED IN 1923 FOR GOLD ORE. NO FURTHER PRODUCTION UNTIL 1946-1949 AND 1953 WHEN A TUNGSTEN OREBODY WAS DISCOVERED

Comment (Geology): SCHEELITE OCCURS IN QUARTZ VEINLETS AND AS CRYSTAL AGGREGATES REPLACING THE LIMESTONE AU OCCURS WITH SULFIDES IN THE QUARTZ

Comment (Deposit): TUNGSTEN OCCURS IN THE COMBINED METALS MEMBER A FEW TENS OF FEET ABOVE THE BASE OF THE PIOCHE SHALE. AG-AU MINERALIZATION OCCURS ALONG THE MAJOR FAULT SYSTEM STRIKING N40W NEAR ITS JUNCTION WITH A N-TRENDING FRACTURE. SILVER BROMIDES AND CHLORIDES OCCUR IN AN AREA OF RECRYSTALLIZED GRAY LIMESTONE 60 FT LONG AND 30 FT WIDE, WITH MINOR GOLD. ABOUT 300 FT E OF THIS AREA, TUNGSTEN MINERALIZATION OCCURS IN AN AREA 300 FT LONG AND 100 FT WIDE WHERE THE LIMESTONE HAS BEEN CRUSHED ADJACENT TO FRACTURES. IN THE CRUSHED ZONES THE FRACTURES HAVE BEEN FILLED WITH LIMONITE,QUARTZ, CALCITE, FELDSPAR, AND SCHEELITE.

Comment (Workings): OLD WORKINGS CONSIST OF 200-FT ADIT WITH STOPING. NEWER WORKINGS 300 FT E OF OLD ADIT CONSIST OF SURFACE STRIPPING (300 X 100 FT) ON 2 BENCHES, AND 2 SHALLOW TEST PITS.
