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 (Deposit): ADDITIONAL WORKINGS ARE APPROX. 600 FT. SOUTHEAST OF THE SERIES OF ADITS AND NEARLY 160-180 FT. ABOVE THE PRINCIPAL, WORKING ADIT. A N83W-S83E, 50 FT. LONG DRIFT IS ENTERED BY A 16 FT. DEEP SHAFT ON ITS WEST END AND A 20 FT. DEEP INCLINED (45 DEGREES) SHAFT ON ITS EAST END. A N80W, 45 NE, 3-5 FT. WIDE ZONE CARRYING PLUMBOJAROSITE, HEMATITE, LIMONITE, AND BARITE WAS WORKED. ; INFO.SRC : 3 FIELD OBSERV; 1 PUB LIT; 2 UNPUB REPT
Comment (Location): LOCATED IN ROYAL GULCH
Comment (Production): AT THE TIME OF NOLAN'S EXAMINATION ON ORE CHUTE EXTENDED FROM THE WORKING ADIT (WENCH NOTED IN 1980) TO THE CANYON BOTTOM; NO FIGURES ARE AVAILABLE, HOWEVER.
Comment (Deposit): THE MINERALIZATION CONSISTS OF REPLACEMENT ORE BODIES LOCALIZED BY BEDDING-PLANE FAULTS AND OTHER FRACTURES (JOINTS, FAULTS).
Comment (Workings): THE PRINCIPAL WORKING IS THE MIDDLE OF THREE ADITS; IT WORKED A 1-3.5 FT. WIDE BEDDING REPLACEMENT ZONE OF BARITE AND GALENA, AND IS APPROX. 200 FT. LONG, INCLUDING DRIFTS. THE LOWER ADIT IS CAVED-IN; THE UPPER ADIT IS ONLY ABOUT 10 FT. LONG AND TRENDS N25E INTO THE SLOPE.
Comment (Geology): CONSIDERABLE GALENA IS PRESENT IN THE PRINCIPAL ADIT; THE ORE IN THE UPPER SOUTHERN WORKINGS IS ALMOST ENTIRELY OXIDIZED.
