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): THE MINE IS SITUATED IN THE LOWER PART OF THE 'GREAT BLUE' LIMESTONE, BELOW THE LONG TRAIL SHALE MEMBER. TWO SILLS OF 'BIRDSEYE' PORPHYRY ARE CUT BY THE LOWER ADIT, BUT THE ORE SEEMS TO BEAR NO RELATION WITH THEM. THE MINE IS DEVELOPED BY TWO ADITS ABOUT 280 FEET VERTICALLY APART, CONNECTED BY MEANS OF AN INCLINED RAISE AND DRIFTS. IN THE UPPER WORKINGS THE ORE SHOOTS CONNECTED WITH THOSE OF THE CHLORIDE POINT MINE, AND LARGE STOPES ARE DEVELOPED THROUGH JASPEROID WALLROCK. THE PRINCIPAL FISSURES IN THE LOWER WORKINGS OF THE MINE ARE THOSE FOLLOWED BY THE MCCLELLAN AND ST. CLAIR INCLINES. THE MCCLLELLAN INCLINE TRENDS N70E, THE ST. CLAIR S65E. THE CLARK INCLINE, JUST WEST OF THE MCCLELLAN, EXTENDS UP FROM THE LOWER OR BUFFALO TUNNEL LEVEL AS A CONTINUATION OF THE DRIFT FROM THE ST. CLAIR INCLINE AND CONNECTS, ON A LEVEL 200 FT HIGHER, WITH THE EAST SIDE TUNNEL. THE MINERALIZATION IS CONTROLLED BY FISSURES. SHOOT ON THE ST. CLAIR FISSURE WAS 2 FT. WIDE AND 12 FT. HIGH OF SOLID GALENA,
Comment (Deposit): BUT PINCHED OUT WHEN FOLLOWED. ON THE UPPER LEVELS THE ORE WAS ALL OXIDIZED, BUT IN THE LOWER PART OF THE MINE IT IS CHIEFLY SULFIDE ORE, ALTHOUGH SOME OXIDIZED MATERIAL IS ALSO FOUND EVER ON THE LOWEST LEVEL. ; INFO.SRC : 1 PUB LIT; 3 FIELD OBSERV
Comment (Production): PRODUCTION DURING 1916-1923: 1925-30; 1934; 1936; PRIOR TO 1932 OUTPUT ESTIMATED AT $150,000; $3.50 A TON IN GOLD; PRODUCTION FIGURES ARE NOT AVAILABLE
Comment (Deposit): ORE ZONES ARE LOCALIZED ALONG FISSURES AND FRACTURES IN DEFORMED AND ALTERED WALLROCKS; ORE ZONES EXTEND 6 TO 8 FT. INTO THE BEDDING FROM THE FISSURES.
Comment (Location): INFO FROM LAND.ST :(1977)
Comment (Workings): TWO ADITS; MANY INCLINES AND RAISES; A TOTAL OF ABOUT 6000 FT. OF WORKINGS; INCLUDES THE MCCLELLAN INCLINE, ST. CLAIR INCLINE, CLARK INCLINE, BUFFALO TUNNEL, EAST SIDE TUNNEL; WORKINGS ARE GENERALLY CAVED AND INACCESSIBLE; UPPER WORKINGS CONNECT WITH THE CHLORIDE POINT MINE
Comment (Geology): LIMESTONES ARE DARK GRAY, BRECCIATED, DOLOMITIZED AND SILICIFIED. SHALES ARE GREENISH GRAY, PULVERIZED, SERICITIC, PILICEOUS, CARBONACEOUS, AND KAOLINITIC. EFFECTS OF LIMONITIZATION ARE FOUND ON HOSTROCKS. VEINS OF JASPEROID, QUARTZ AND SILICA HAVE IMPREGNATED THE WALLROCKS. ORE MINERALS ARE ASSOCIATED WITH SILICIFIED ZONES
