General comments

Subject category Comment text
Deposit LENGTH OF MINERALIZED ZONE RANGES FROM TENS TO HUNDREDS OF FEET LONG. VEINS LIE ALONG STRIKE AND COULD BE PART OF SAME VEIN OR SEPARATE VEINS ALONG SAME STRUCTURE.
Deposit SHEARING IS AS PRONOUNCED IN GRANITIC ROCK AS IN QUARTZITE. QUARTZITES ARE MORE FAVORABLE HOST TO VEINS THAN QUARTZ MONZONITE ; INFO.SRC : 1 PUB LIT
