Subject category Comment text
Deposit 18 INCHES WAS WIDEST WIDTH OBSERVED IN 1961 . WIDTHS ARE PROBABLY GREATER THAN THIS WITHIN INACCESSIBLE PORTIONS OF MINE WORKINGS: ORE VEINS LESS THAN 18 INCHES WIDE WERE NEVER MINED.
Deposit MOST PRODUCTIVE PART OF MINE IS WITHIN AND ABOVE UPPER ADIT. WALL ROCK IN UPPER ADIT IS ARGILLACEOUS QUARTZITE & LIGHT-GREY QUARTZITE. LOWER ADITS WERE DRIVEN ALONG GENERALLY BARREN FAULTS. WALL ROCK IN THESE ADITS IS ESSENTIALLY THIN-BEDDED MEDIUM GREY ARGILLITE WITH SOME QUARTZITE. ; INFO.SRC : 1 PUB LIT
