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.

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): UNSURVEYED ; INFO FROM LAND.ST :1972
Comment (Development): NO ACTIVITY AT TIME OF EXAMINATION IN 1983, BUT AREA IS PROBABLY STAKED.
Comment (Deposit): ELONGATE PROSPECT IN NW PART OF MINE AREA PROVIDES GOOD EXPOSURE OF GEOLOGY. PROPYLITIZED, SILICIFIED ANDESITES. VOLCANICS CUT BY MAFIC DIKES AND A N25W SHEAR ZONE. QUARTZ VEINS PARALLEL THE SHEAR ZONE FORMING A SHEETED VEIN SYSTEM. SHEAR ZONE 10-30 FT WIDE. SLICKENSIDES WITHIN THE ZONE ARE STEEPLY INCLINED AND COATED BY FE OXIDES AND QUARTZ. THE QUARTZ VEINS ARE GENERALLY SUBPARALLEL AND NUMEROUS. MANY ARE EMPLACED ALONG BOTH HIGH AND LOW-ANGLE FRACTURES. MOST OF THE VEINS ARE VUGGY, OPEN-CENTERED FISSURE-TYPE. THE VEINS ARE COMPOSED OF WHITE MASSIVE-COMB AND SUGARY QUARTZ. SOME OF THE VEINS ARE STEEPLY INCLINED AND OTHERS ARE SHALLOW OR ALMOST HORIZONTAL. ON EAST SIDE OF TRENCH THERE IS A 1-2 FT WIDE MASSIVE TO VUGGY QUARTZ VEIN AND QUARTZ-VEINED BRECCIA WHICH DIPS ABOUT 45 TO THE EAST. THIS IS PROBABLY THE HEART OF THE MAIN PENNSYLVANIA VEIN. THE ANDESITES IMMEDIATELY WEST OF THE VEIN ARE IRON-STAINED AND LACED WITH QUARTZ VEINS AND VEINLETS WHICH ARE MOSTLY N-NW-STRIKING AND MORE
Comment (Deposit): STEEPLY INCLINED THAN IS THE MAIN VEIN. RELATIVELY SMALL AMOUNT OF FE AND MN OXIDES IS ASSOCIATED WITH VEIN MATERIAL, AND IN GENERAL THE QUARTZ CONTAINS ONLY A SMALL AMOUNT OF FINELY CRYSTALLINE PYR
Comment (Workings): ORIGINAL WORKINGS POSSIBLY CAVED OR OBLITERATED BY TRENCHING. EXISTING WORKINGS CONSIST OF SEVERAL CONNECTING SHALLOW PROSPECTS AND TRENCHES. OLD TIMBERS AND PILES OF ORE IN AREA
