Thor Mine

The Thor Mine is a gold and silver mine located in Lincoln county, Nevada at an elevation of 6,841 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: Private
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): INFO FROM LAND.ST :1982

Comment (Deposit): FRAGMENTS OF SILICIFIED FE-REPLACED ANDESITE WHICH SHOW FINE VITREOUS QUARTZ VEINLETS PRE-DATING BRECCIATION ARE CONTAINED IN MASSIVE TO PRISMATIC WHITE VEIN QUARTZ ON DUMP. VEINS HAVE OPEN CENTERS, ARE TYPICALLY BANDED WHITE TO CLEAR IN APPEARANCE, ARE FE-STAINED AND SHOW FE-STAINED, QUARTZ-ENCRUSTED VUGS. ALTHOUGH THE VEINS CONTAIN SCARCE CRYSTALS OF FINE-GRAINED PYRITE, IT IS LESS THAN THAT OBSERVED IN SIMILAR VEIN MATERIAL AT THE JENNIE MINE. DARK STREAKS AND LENSES IN VEIN MATERIAL ARE PROBABLY DISPERSED SULFIDES OR POSSIBLY AG-BEARING MINERALS. CLOTS OF LIMONITE AND MN OXIDES ARE FOUND BUT NOT IN ABUNDANCE. QUARTZ AFTER CALCITE TEXTURES ARE COMMON. TYPICAL VEIN WIDTH IS 1-3 IN WITH SUBPARALLEL VEINS FORMING WIDTHS UP TO 1-2 FT. A QUARTZ VEIN OBSERVED CUTTING THE ANDESITE AT THE PORTAL STRIKES N50E AND DIPS 80 NW. IT IS TYPICAL OFTHE SECONDARY VEINS NOTED THROUGH OUT THE DISTRICT WHICH ARE PROBABLY UNMINERALIZED. IT IS 3 IN WIDE, BANDED, VUGGY AND FE-STAINED

Comment (Development): AT TIME OF EXAMINATION IN 1983, A TRUCK-SUPPORTED DRILL RIG WAS OPERATING NEAR ROAD JUNCTION JUST NORTH OF MINE

Comment (Workings): 2 OPEN CUTS, 2 ADITS. THE THOR ADIT, DRIVEN E FOR 240 FT, CROSSCUTS THE THOR VEIN 65 FT FROM THE PORTAL. AT THIS POINT, A DRIFT FOLLOWS THE VEIN SOUTH FOR 140 FT. AT 120 FT FROM THE PORTAL, ANOTHER DRIFT TO THE SOUTH WAS DRIVEN ALONG A SMALL CALCITE FISSURE. ANOTHER ADIT WAS DRIVEN TO CUT THE VEIN SOUTH OF THE THOR ADIT. REMAINS OF 3 CABINS, INCLINED TRACK FROM OPEN CUTS TO ORE BIN STILL EXIST. SOME FAIRLY RECENT BULLDOZING OF DUMP MATERIAL AND OUTCROP ABOVE AND BELOW WORKINGS
