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.

Comments
Comment (Development): PROPERTY APPEARS TO HAVE BEEN RELATIVELY INACTIVE FOR A NUMBER OF YEARS. MINE POSSIBLY HAS SOME SMALL SCALE ACTIVITY ON AN INTERMITTENT BASIS. THIS IS THE LARGEST PRODUCER OF THE GOLD SPRINGS DISTRICT
Comment (Deposit): Discovery Year: 1900 OR EARLIER
Comment (Location): MINE LIES ON NEVADA-UTAH BORDER WITH WORKINGS IN BOTH STATES
Comment (Deposit): VEIN IS WELL EXPOSED IN NORTH WALL OF LOWER SHAFT WHERE IT FORMS A RESISTANT WHITE KNOB 7-10 FT WIDE. VEIN HAS SHARP BUT UNDULATORY CONTACTS WITH THE ALTERED ANDESITE WALLROCK, AND SHOWS SLIGHT "PINCH AND SWELL" SHAPE. IRON-STAINED ANDESITE ADJACENT TO THE VEIN IS FRACTURED AND VEINED PARALLEL TO THE MAIN VEIN ORIENTATION. VEINING OF THE WALL ROCK IS COMMON IN BOTH HANGING AND FOOT WALL EXPOSURES EXTENDING OUTWARD FROM MAIN VEIN ABOUT 5 FT. QUARTZ, CALCITE VEIN, AND QUARTZ VEIN WITH ANDESITE BRECCIA FRAGMENTS ARE THE MOST ABUNDANT ROCK TYPES ON THE LARGE DUMP. ALL VARIETIES OF QUARTZ-CALCITE COMBINATIONS EXIST, IE. QUARTZ REPLACING CALCITE, INTERGROWN WITH CALCITE, QUARTZ CUT BY OR CUTTING CALCITE VEIN. CALCITE IS GENERALLY WHITE, COARSELY CRYSTALLINE AND CONTAINS LITTLE FE. THE QUARTZ IS GENERALLY SUGARY OR MASSIVE, WHITE, AND ALSO OCCURS AS RADIATING OR PRISMATIC INTERLOCKING CRYSTALS IN VEINS AND BRECCIA. MOST VEINS ARE OPEN-CENTERED AND DRUSY QUARTZ FILLS VUGS AND FRACTURES OR
Comment (Deposit): REPLACES CALCITE. THE ALTERED ANDESITE FRAGMENTS CONTAINED IN THE VEIN ARE HIGHLY SILICIFIED AND STAINED WITH LIMONITE AFTER PYRITE. SOME OF THE FRAGMENTS SHOW A STOCK WORK OF VITREOUS QUARTZ VEINLETS
Comment (Workings): STOPES AND OPEN SHAFTS INCLINED ALONG VEIN STRUCTURE. MILLSITE STILL REMAINS INTACT (1983) AS SO SEVERAL LARGE HEAD FRAMES, ASSAY LABS, ETC. OLD DRILL ROADS IN AREA. MINE WAS DEVELOPED ON THE 60-, 100-, 200, AND 300-FT LEVELS WITH DRIFTS NW AND SE ALONG VEIN
