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 (Commodity): ALL ORE MINERALS OXIDIZED; NO SULFIDES SEEN
Comment (Location): IN HEADWATERS OF JOHNSON CANYON 0.8 MILE NNE OF TANKS PEAK ; INFO FROM LAND.ST :(1975)
Comment (Deposit): Discovery Year: 1870S
Comment (Workings): ONE SHAFT AND THREE VERTICALLY ARRANGED TUNNELS CONTAINING SEVERAL HUNDRED FEET OF DRIFTS AND SMALL STOPES
Comment (Deposit): DEPOSIT LIES IN WEAK SHEAR ZONE OF NEARLY VERTICAL FRACTURES STRIKING N 40 TO 60 E AND PROBABLY RELATED TO YAMPA REVERSE FAULT TO NORTH. FRACTURES CONTAIN VEINS AND MINERALIZED BRECCIA OF OXIDIZED ZN AND CU ORES EXTENDING ACROSS CONTACT OF MADISON LIMESTONE AND QUARTZITE AND SHALE OF LODORE FM. ORES ARE UNUSUAL AMONG THOSE THAT DIRECTLY REPLACE SULFIDES IN THAT THEY ARE LEAN IN FE, PB, AND AG. LOW AG CONTENT SUGGESTS PRIMARY ORES DEPOSITED BY LOW-TEMP EPITHERMAL SOLUTIONS FAR FROM THEIR SOURCE.
