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 (Deposit): THREE MAIN VEINS 5 - 10 FT. IN THICKNESS, STRIKE N TO NE AND DIP STEEPLY. MAIN VEIN KIDNEY VEIN, WEST VEIN LOW-GRADE MATERIAL. THE KIDNEY VEIN STRIKES NORTH BETWEEN THE SURFACE AND THE 350-FOOT LEVEL. BELOW THIS LEVEL THE STRIKE SWINGS TO THE NORTHEAST. FROM THE 350- AND 500-FOOT LEVELS, THE VEIN DIPS 45 DEG. E, BUT BELOW THE 500-FOOT LEVEL IT STEEPENS TO 74 DEG. SE. A NUMBER OF KIDNEY-SHAPED ORE SHOOTS WERE DEVELOPED BETWEEN THE SURFACE AND 500-FOOT LEVEL. THE MAIN ORE SHOOT WAS CONTINUOUS BETWEEN THE 500-AND 1200-FOOT LEVELS; BELOW THE 1200-FOOT LEVEL, THE GRADE DECREASED GREATLY.

Comment (Workings): THE MINE IS DEVELOPED BY A 1200-FOOT VERTICAL SHAFT, WITH CROSSCUTS TO THE VEIN. LEVELS ARE AT 100 , 200 , 300 , 350 , 500 , 600 , 700 , 850 , 1000 , AND 1200 FEET. ON THE 1200-FOOT LEVEL, A 670-FOOT CROSSCUT EXTENDS EAST TO THE VEIN, FROM WHICH A WINZE WAS SUNK ON THE VEIN TO THE 1400-FOOT LEVEL. ON THE 600- AND 1200-FOOT LEVELS, DRIFTS EXTEND NORTH AND SOUTH TO THE PROPERTY LINE.

Comment (Geology): VEINS IN MARIPOSA SLATE

Comment (Commodity): THE BEST ORE, $30 PER TON, WAS MINED DURING THE EARLIER OPERATIONS. ORE MILLED FROM AS FAR DOWN AS THE 1300-FOOT LEVEL HAD AVERAGED $17 PER TON. BELOW THAT LEVEL IT DECREASED TO $4 PER TON OR LESS. SULFIDES ASSAYED AS HIGH AS $140 PER TON IN GOLD. CONSIDERABLE AMOUNTS OF GOUGE WERE PRESENT ESPECIALLY IN THE LOWER LEVELS. SOME OF THE GOUGE CARRIED SOME GOLD.

Comment (Location): UTM ACC. NE 1/4 SEC.

Comment (Production): ACTIVE 1850'S, 1860'S, 1880'S, 1890'S, 1900 - 1907 , 1941 - 1942
