Comments

Comment (Deposit): 2 VEINS - BIG DICK STRIKES N AND DIPS 20N. BLANKET VEIN - STRIKES E AND DIPS 20N. BLANKET VEIN CUTS THE OTHER AND IS THE MAIN SOURCE FOR THE MINE. THE FOLDING SQUEEZED AND CRUSHED THE ROCKS, OPENING THEM FOR MINERALIZING SOLUTIONS WHICH PARTLY REPLACED THEM WITH SILICA AND INTRODUCED A LITTLE GOLD-BEARING PYRITE.
