Deposit THE MINE IS ON A SMALL KNOB ON THE EAST SIDE OF THE KRUM HILLS HOSTED IN SHALES AND SILTSTONES OF THE RASBERRY FM. MANY OF THE VEINS OCCUPY NE-TRENDING SHEARS WHILE OTHERS ONLY PARTLY FILL THE SHEARS; MOST DIP WEST AT STEEP ANGLES. DUMPS NEAR THE BIG SHAFT ARE EXTENSIVE AND FILLED WITH PYRITE, AND OTHER SULFIDES. SMALL ADITS ALONG NE SHEARS ARE REMNANTS OF EARLIER ACTIVITY IN THE CAMP. SAMPLE 2374 WAS A HIGH-GRADE CHALCOPYRITE, ARSENOPYRITE, SPHALERITE, TETRAHEDRITE, AND POSSIBLY AU/AG MINERALIZATION. SAMPLE 2375 WAS A COMPOSITE SAMPLE OF QUARTZ VEIN MATERIAL FROM THE MAIN DUMPS, AND INCLUDED BRECCIAS WITH VISIBLE TETRAHEDRITE AND GALENA AS WELL AS ARSENOPYRITE AND PYRITE.; MODEL NAME COULD ALSO BE: POLYMETALLIC VEINS.
Deposit CONSISTS OF SUNPATENTED CLAIMS ADJOINING THE NEVADA CONSOLIDATED MINES CO. MOST OF THE $142,628 PRODUCED IN THE DISTRICT IN 1942 PROBABLY CAME FROM THIS MINE. THERE WAS SPORADIC OPERATION OF THE MINE AFTER WWII BUT NO RECORD OF ITS PRODUCTIONS DEVELOPMENT CONSISTS OF SEVERAL ADITS, A 180 FT DEEP SHAFT, AND 1600 FT OF OTHER WORKINGS. IN 1972 THE PROPERTY WAS LEASED TO ALPINE MINERALS, INC., AND SUBLEASED TO JACK WILSON. IN 1907, THE FIRST CLAIMS WERE STAKED ON THE VEINS OF THE PRESENT WORKINGS. IN 1910, SMALL-SCALE PRODUCTION WAS BEGUN LASTING FOR SEVERAL YEARS, BY THE 1910 MINING CO. FROM THEN UNTIL 1938, ONLY SPORADIC LEASING AND PROSPECTING OCCURD, UNTIL THE WEST COAST MINES CO. TOOK IT OVER IN 1937. BIGGEST PRODUCTION- 1941. LARGEST AG-PRODUCTION IN NEVADA AT THAT TIME. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV
