Deposit LONG, NARROW, LENTICULAR REPLACEMENT ALONG BEDDING IN AGRILLITE AND CHERT. IT FEATHERS OUT IN ALL DIRECTIONS. 3 DISCONTINUOUS OREBODIES ELONGATED ALONG STRIKE OF HOST ROCKS, UP TO 820 FT. LONG.
Deposit THE PROPERTY COMPRISES FIVE UNPATENTED MINING CLAIMS LOCATED IN 1934. THE ONLY DEVELOPEMENT IN 1950 WERE TWO SHORT ADITS. THE USBM UNDERTOOK EXPLORATION OF THE PROPERTY IN 1940 WITH A PROGRAM OF MAPPING, SAMPLING, TRENCHING, AND DRILLING.
