Mine Info

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 (Workings): TWO VEINS HAVE BEEN DEVELOPED ON THE LOWER TUNNEL KNOWN AS FOOTWALL AND HANGING WALL VEINS. THE LOWER OR MAIN WORKING TUNNEL IS DRIVEN S 40 W, 1980 FT. AT 800 FT FROM THE PORTAL, A WINZE HAS BEEN SUNK ON THE FOOTWALL VEIN TO A DEPTH OF 200 FT. AT 165 FT BELOW THE COLLAR OF THE WINZE, A LEVEL HAS BEEN DRIVEN ON THE VEIN 100 FT TO THE NORTHEAST AND 180 FT TO THE SOUTHWEST. NEAR THE LOCATION OF THE WINZE A RAISE HAS BEEN PUT UP 95 FT TO NO. 4 TUNNEL. NO. 6 LOWER TUNNEL HAS BEEN ADVANCED A TOTAL DISTANCE OF 1980 FT. IN THE FACE OF THIS TUNNEL THERE IS A VEIN OF QUARTZ THREE FEET IN WIDTH. ABOUT 600 FT WOUTH OF WINZE, THERE IS A RAISE 122 FT. ABOVE TUNNEL IN THE FOOTWALL OF THE VEIN. AT 450 FT SOUTH OF THIS RAISE, A RAISE HAS BEEN PUT UP 117 FT INTERSECTING THE SUMNER TUNNEL LEVEL (NO. 3 TUNNEL). AT 150 FT SOUTH OF THIS RAISE, A WINZE IS SUNK ON THE VEIN 50 FT. WIDTH OF VEIN ENCOUNTERED IN WINZE SHOWS THREE FEET OF QUARTZ. WORKINGS ON THE VEIN ARE AS FOLLOWS: NO. 6 LOWER TUNNEL 1980 FT,

Comment (Workings): NO. 4 TUNNEL, 104 FT IN ELEVATION ABOVE NO. 5 775 FT, NO. 3 TUNNEL, 119 FT ABOVE N9. 5, 735 FT, NO. 2 TUNNEL, 145 FT ABOVE NO. 4, 450 FT. ON NO. 2 TUNNEL, WHICH IS LOCATED ON THE SOUTHWEST SLOPE OF THE HILL, THE MCGILL ORE-SHOOT IS STATED TO HAVE BEEN 280 FT LONG, WITH AN AVERAGE WIDTH OF 4 FT. THIS SHOOT WAS STOPED TO THE SURFACE A DISTANCE OF 150 FT. TUNNEL NO. 3 DEVELOPED THE TOM LANE ORE-SHOOT, WHICH IS STATED TO HAVE BEEN 160 FT. LONG, BY 120 FT. HIGH AND WITH AN AVERAGE WIDTH OF 4 FT. TUNNEL NO. 4 DEVELOPED THE HIGGINS ORE-SHOOT, WHICH WAS 500 FT LONG AND 150 FT HIGH, AVERAGE WIDTH BEING 4 FT. IN THE WINZE ON TUNNEL NO. 5 AN ORE-SHOOT 120 FT LONG BY 3 FT WIDE HAS BEEN DEVELOPED.

Comment (Deposit): 12 CLAIMS.

Comment (Production): GOLD RAN $20-$54/TON FROM TUNNEL 2; ORE FROM WINZE IN TUNNEL 5 RAN $17/TON, $20,000 TOTAL. CALIFORNIA JOURNAL OF MINES AND GEOLOGY, VOL. 25 REPORTS A PRODUCTION FIGURE OF $3000000 FOR SIXTY YEARS SINCE ITS DISCOVERY IN 1855.
