General comments

Subject category Comment text
Deposit THE DEEP SULFIDE ORE COULD NOT BE HANDLED IN THE 1800'S. ; INFO.SRC : 1 PUB LIT
Deposit ORE BODIES OCCUR AS NARROW ECHELON LENSES IN ARGILLITE AND FELSITE; OXIDIZED ORE IS MANGANIFEROUS, LIMONITIC, SILICEOUS MATERIAL; MORE SILICEOUS THAN AVERAGE OF DISTRICT. PRODUCTIVE ORE IS NEAR LOWER BORDER OF CANDELARIA SHALE.
