Satelite View

The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Location): IN BARBER CANYON
Comment (Deposit): WORKINGS FOLLOW FLAT-DIPPING SHEETED ZONE IN META-VOLCANIC WALLROCK; ROCK IS CHLORITIZED; SHEETED ZONE IS LACED WI-TH QUARTZ. QUARTZ CONTAINS CLOTS AND EUHEDRAL CUBES OF LIMONIT-E-AFTER-PYRITE, FREE GOLD OCCURS IN LIMONITE. VEINED SHEAR ZON-E STRIKES ABOUT N70E, DIPS 20 NW, IS ABOUT 15 FT THICK AS EXPO-SED IN THE ADIT AND GLORY HOLE. A N-S-STRIKING VERTICAL SHEAR -ZONE CUTS THE FLAT-DIPPING ZONE ALONG THE EAST WALL OF THE ADI-T.
Comment (Workings): SHALLOW ADIT LEADING INTO GLORY HOLE, SURFACE CUTS
Comment (Development): NO ACTIVITY AT TIME OF EXAMINATION IN 1985, BUT SOME RECENT TRENCHING; ROTARY DRILLING WITHIN PAST 10-15 YRS. MINE-D IN 1930'S AND LATER BY BILL SWETT AND FATHER IMLAY.
