Deposit OPENED IN 1880'S, WORKED INTERMITTENTLY UNTIL 1942 WAS LARGEST GOLD OPERATION IN BARSTOW-VICTERVILLA AREA. 3 PATENTED CLAIMS ; INFO.SRC : 1 PUB LIT
Deposit SILICEOUS VEIN IN FAULT, EXPOSED LATERALLY FOR 3000 FT. STRIKE OF VEINS ARE VARIABLE ACCORDING TO BOWEN, FROM N80E, AT SURFACE, TO N80W. VEINS APPEAR TO BE DISCONTINUOUS. IN VICINITY OF DOHERTY SHAFT, HANGING WALL ROCKS ARE META-DACITES AND META-FELSITES OF THE SIDEWINDER VOLCANIC SERIES, AND FOOTWALL IS QT. MONZONITE. IN MOST EASTERN WORKINGS, BOTH WALLS ARE HYDROTHERMALLY ALTERED FELSIT. BOTH WALLS ARE QT. MONZONITE IN MOST EASTERLY OF 3 WEST SHAFTS.
