Denton Summit Workings

The Denton Summit Workings is a tungsten, gold, and silver mine located in Lincoln county, Nevada at an elevation of 6,850 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 (Deposit): DUMP ROCKS SHOW FINE SILICEOUS VEINING AND MINUTE CLOTS OF PARTIALLY OXIDIZED PYRITE. ABOVE AND NE OF ADIT, MICACEOUS BROWN SHALES OUTCROP ALONG SLOPE BELOW A SANDY LIMEY HORIZON WHICH IS ALTERED TO A LIGHT GREEN DENSE BANDED CALC-SILICATE WHICH IS FINE-GRAINED AND CONTAINS ABUNDANT EPIDOTE AND CALCITE. THE CALC-SILICATE HORIZON EXTENDS TO DRILL ROAD LOCATED ABOUT 30 FT ABOVE ADIT. THE ROCKS ON THE DRILL ROAD ARE MICACEOUS BROWN AND GREEN SHALES. SOME OF THE SHALES ARE LIMEY AND ALSO SHOW SILICATION EFFECTS: MICA IN THE SHALES IS RECRYSTALLIZED IN RESPONSE TO THERMAL(?) METAMORPHISM. THE SHALES AND LIMEY MUDSTONES FORM 1-6 INCH BEDS WHICH STRIKE N65E AND DIP 30 SE. HOWEVER, ATTITUDES ON BEDDING CHANGE DUE TO SMALL NNW-STRIKING FAULTS OBSERVED IN ROAD CUT AND A LARGER E-W FAULT MAPPED IN AREA BY CALLAGHAN (1937). A LARGE RHYOLITE DIKE IS LOCATED ABOUT 0.25 MILE WEST OF SAMPLED OUTCROP. A FEW MINUTE FLAKES OF SCHEELITE WERE OBSERVED WHEN CALC-SILICATE SAMPLE WAS LAMPED.

Comment (Workings): ONE CAVED ADIT AND SMALL DUMP. DRILL ROAD LIES ABOVE ADIT AND HAS DRILL HOLES SPACED APPROXIMATELY EVERY 20 FT.

Comment (Development): NO ACTIVITY AT TIME OF EXAMINATION IN 1983, BUT DRILLING IN AREA PROBABLY COMPLETED 3-5 YEARS AGO.

Comment (Location): AREA IS UNSURVEYED ; INFO FROM LAND.ST :1972
