Deposit SHEAR ZONE 180 FT WIDE AND 540 FT LONG IS TERMINATED BY A FAULT ALONG ITS NORTHERN SIDE. MASSIVE SULFIDE BODIES OCCUR ALONG WALLS OF ZONE, WHICH IS DELIMITED BY FAULTS. COUNTRY ROCK IN CENTER OF ZONE CONTAINS DISSEMINATED SULFIDES WITH POCKETS OF MASSIVE SULFIDES AND POCKETS OF BARREN GREENSTONE. MAGNETIC SURVEY INDICATES TWO LARGE UNEXPLORED MASSIVE SULFIDE BODIES TO THE NORTH AND TO THE SOUTH ON STRIKE WITH DEPOSIT.
