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 (Development): 16 CONTIGUOUS MINING CLAIMS, THE CLAIM NAMES ARE: CUMBERLAND, MERRIMAC RICHMOND, RICHMOND ANNEX, MONITOR, TUCSON, MOUNTAIN MAID, ADMIRAL DEWEY, STARE BLACK EAGLE, LINCOLN TIP TOP, WOODROW WILSON, SILVER CANYON NOS. 1,2,3
Comment (Deposit): SAME MINERAL BELT AS IS FOUND AT THE RAY MINE, SEVERAL VEINS ON THE CLAIM, 1 MAINS AND 5 SMALLER VEINS.
Comment (Location): INFO FROM LAND.ST :(1978)
Comment (Workings): THE GROUP OF CLAIMS ARE THOROUGHLY PROSPECTED BY TUNNELS, SHAFTS, DRIFTS, WINZES, AND DISCOVERY CUTS. ABOUT 2500 FT OF UNDER GROUND WORK HAS BEEN COMPLETED ON THE PROPERTIES. THE MONITOR MINE IS THE MOST EXTENSIVELY DEVELOPED OF THE GROUP. THE SHAFT WAS SUNK ON THE CENTRAL VEIN OF THE CLAIM. SOUTH OF THE MAIN SHAFT, ANOTHER SHAFT WAS SUNK ABOUT 20 FT. ALSO PRESENT ON THE MONITOR CLAIM ARE 3 SMALL SURFACE CUTS AND TWO OTHER TUNNES, ON THE RICHMOND, DEWEY, TUCSON, MOUNTAIN VIEW, CUMBERLAND AND MERRIMAC CLAIMS, VARIOUS SHAFTS, AND UNDERGROUND WORKINGS HAVE BEEN DONE. SOME SOURCES REFER TO THESE CLAIMS AS MINES, IE DEWEY MINE, MERRIMAC MINE ETC.
Comment (Geology): 3 1/2 MILES NE OF RAY MINE, AGE OF MINERALIZATION SAME AS RAY MINE AND RHYODACITE PORPHYRY IS SAME AGE.
