General comments

Subject category Comment text
Deposit PYRITE AND GOLD MINERALIZATION OCCUR IN QUARTZ VEINS, STOCKWORKS AND REPLACEMENTS ALONG A FAULT IN OLIVE SILSTONE AND SANDSTONE, MUCH OF THE PYRITE IS OXIDIZED TO LIMONITE IN THE ZONE. THE ELONGATE OPEN PIT FOLLOWS THE FAULT ZONE; APPARENTLY FAULT BRECCIATION AND LATER SILIFICATION AND VEINING EXTENDED FOR A CONSIDERABLE DISTANCE AWAY FROM THE FAULT. THE MAJORITY OF THE PIT IS IN THE APPARENT HANGING WALL OF THE FAULT, AS A MAJOR STRAND GENERALLY LIES ON THE EAST SIDE OF THE PIT. THE CONTINUATION OF THE VEIN TO THE SOUTH OF THIS PIT PASSES THROUGH PITS OF THE ADELAIDE CROWN MINES, WHERE IT STILL TRENDS DUE NORTH, BUT DIPS 70W.
