Satelite View

The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Location): (LAND STATUS AND ADMINISTRATIVE AREA LOCATIONS CALCULATED USING GIS OVERLAY ANALYSIS FOR SAN JUAN N. F.). CLAIMS LIE ON NORTH SIDE OF UPPER NAVAJO BASIN SW OF ROCK OF AGES MINE AND ONE MILE SW OF WILSON PEAK. ELEV AND LAT-LONG GIVEN ARE FOR APPROXIMATE SITE OF ZERO ADIT (S2 SW SEC. 32). ; INFO FROM LAND.ST :41? 01 1975
Comment (Workings): ZERO ADIT DRIVEN ALONG VEIN AT N 65 TO 75 E; CAVED AT 180 FT FROM PORTAL
Comment (Deposit): IN NORTH-CENTRAL PART OF WILSON PEAK STOCK, CHALCOPYRITE OCCURS (1) DISSEMINATED IN ADAMELLITE (QUARTZ MONZONITE), (2) ALONG MINOR FRACTURES, AND (3) IN NARROW AURIFEROUS QUARTZ VEINS WITH PYRITE, MINOR GALENA AND SPHALERITE. ZERO VEIN FOLLOWS 2- TO 6-INCH-WIDE FISSURE TRENDING N 65 TO 75 E, DIPPING STEEPLY SE TO VERTICAL, AND SHOWING CONSPICUOUS SECONDARY CU MINERALS. DISSEMINATED CHALCOPYRITE OCCURS IN POORLY OUTLINED AREA EXTENDING EASTWARD FROM ADIT ABOUT 1000 FT, WITH VISIBLE CARBONATE STAINING AT LEAST 100 FT ABOVE PORTAL. ALTERED ROCKS ALSO SHOW COMMON QUARTZ VEINLETS AND FRACTURE COATINGS AND SERICITIZED FELDSPAR. VISIBLE MOLYBDENITE FOUND ON DUMP OF CAVED ADIT 400 FT BELOW ZERO ADIT.
