Subject category Comment text
Deposit ORE ZONE 500 FEET LONG AND 10 TO 40 FEET WIDE FOUND IN TACTITE AND LIMESTONE ALONG CONTACT WITH GRANITIC ROCK; IT IS A REPLACEMENT OF A FAVORABLE BED. THE EASTERN 2/3 IS NARROW AND CONSISTS MAINLY OF VEINLETS AND PODS OF INTERMIXED MAGNETITE AND TACTITE. IN WESTERN 1/3 THE ZONE WIDENS TO ABOUT 40 FEET AND FOR LENGTH OF 200 FEET IS LARGELY IRON ORE WITH LITTLE WASTE.
