Subject category Comment text
Deposit DEPOSITS ARE OF REPLACEMENT ORIGIN. SIX TO EIGHT ORE BODIES WERE DISCOVERED. ORE BODIES ARE CONFORMABLE TO BEDDING, ELONGATE IN AN EAST WEST DIRECTION, AND PRIMARILY HOSTED BY HIGHLY SHATTERED MAXFIELD LIMESTONE. ENTIRE MINE AREA IS 1200 FT LONG BY 400 FT WIDE. MINERALIZING SOLUTIONS CAME UP ALONG EAST STRIKING FISSURES AND REPLACED LIMESTONE. OXIDATION HAS BEEN EXTREME
