Satelite View

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

Comments
Comment (Geology): TO 20 FT THICK BANDED QTZ VEIN MOSTLY W/I SLATE, 43-65 W DIP, SOMETIMES FOLLOWS SERPENTINE CONTACT. SERPENTINE INTENSELY ALTERED TO CARBONATE-MARIPOSITE MIXTURE, FORMS FOOTWALL IN PLACES. POST MINERAL ANDESITE HANGING WALL & DIKE WHICH IN ONE PLACE CROSSES VEIN & INTRUDES SERPENTINE. IN MOST PLACES A STRIP OF CRUSHED SLATE IS BETWEEN DIKE & VEIN. A WELLMARKED FOOTWALL SLIP SEPERATES VEIN QTZ FROM ALTERED SERPENTINE, NEAR AMERICAN TUNNEL PORTAL. ELSE WHERE 50 FT THICK ALTERED SERPENTINE CUT BY GOUGE-BEARING SLIPS, AGAINST FRESH SERPENTINE WHICH DIPS WESTWARD. ELSEWHERE QTZ IS IN STRINGERS, OR BANDED, IN ALTERED & UNALTERED SLATE. A MILE NORTH A QTZ VEIN STRIKES N 20 W AND DIPS FROM STEEP TO FLAT TO W, DUE TO SURFACE SLIDING POSSIBLY, AND AT SURFACE IS 6 - 8 FT THICK, HERE W VERT DIP. THIS VEIN LIES BETWEEN CHLORITIC SCHIST & SERPENTINE TO EAST.
Comment (Commodity): 3 SMALL BUNCHES OF HIGH GRADE ORE. SMALL SHOOT OF HIGH GRADE ORE; WHERE QTZ-CARBONATE-MARIPOSITE MIX. ORE YIELDED $8.50/TON. IN SHOOT ON 2ND LEVEL, A VEINLET OF DENSE BLUISH QTZ CROSSING WHITE COARSE QTZ REPORTED TO CARRY MUCH COARSE GOLD. OLD LENTICULAR QTZ BODY SAID TO BE EXTREMELY RICH.
Comment (Location): UTM EST. ADIT SHOWN IN SEC 17.
Comment (Production): APPARENTLY IDLE FROM 1875 - 1923 , FROM 1923 - 27 . A FEW THOUSAND DOLLARS WAS PRODUCED. NO OTHER PRODUCTION RECORD FOUND.
Comment (Deposit): VEINS, ORE SHOOTS
Comment (Workings): ORIGINAL INCLINED SHAFT OF 520 FT. W SHORT LEVELS, CAVED. RECENT ADIT 2200 FT. CONNECTS W OLD SHAFT, 220 FT. DEEP WINZE. OTHER ADITS, SURFACE WORKS.
