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.

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.
