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 (Location): ACCURATE LOCATION IS FOR THE ENTRANCE OF DEEP TUNNEL AS SHOWN ON THE UTE PARK TOPOGRAPHIC QUADRANGLE.. DEEP TUNNEL CONNECTS WITH BALDY TUNNEL WHICH IS LOCATED ABOUT 8000 FT. WEST-SOUTHWEST OF DEEP TUNNEL, NEAR THE SPRINGS AT THE HEAD OF BIGNEGRO GULCH. CADASTRAL GRID PROJECTED.
Comment (Production): PRODUCTION OF ABOUT ONE TON OF GOLD ORE IN 1919.
Comment (Development): HE COST OF DRIVING BOTH TUNNELS IS REPORTED TO BE A ROUND 2 MILLION DOLLARS.
Comment (Deposit): ONE TUNNEL SITE AND 18 CLAIMS COVERING ABOUT 415 ACRES.
Comment (Workings): THE DEEP TUNNEL WAS DRIVEN WESTWARD FOR NEARLY 2200 FT TO CONNECT WITH THE BALDY TUNNEL WHICH WAS DRIVEN EASTWARD FOR ABOUT 7000 FT. FROM THE PORTAL. WORK BEGAN IN THE BALDY T UNNEL IN 1900 AND CONTINUED INTERMITTENTLY FOR 36 YEARS.
Comment (Geology): MOLYBDENUM MINERALIZATION IN THE TUNNEL IS SPARSELY DISTRIBUTED AND OCCURS AS COATINGS AND STRINGERS IN QUARTZ-PYRITE VEINS WHOSE AVERAGE WIDTH IS TWO INCHES. MOST VEINS STRIKE NORTH-SOUTH AND DIP STEEPLY EAST, ALTHOUGH VARIATIONS IN BOTHSTRIKE AND DIP OCCUR. MOLYBDENITE OCCURS NEAR THE MIDDLE OF T HE TUNNEL FOR A LENGTH OF 1825 FT. AND A WIDTH OF 800 FT. MOLYBDENITE CROPS OUT ON THE SURFACE IN VEINS AND FLOAT ABOUT 1800 FT. ABOVE THE TUNNEL. THE VEINS ARE REPORTED TO BE NEITHER AS RICH, NOR AS CLOSELY SPACED AS VEINS AT THE QUESTA MOLY MINE.
