Deposit WORKINGS MAY BE ACCESSIBLE WITH SOME WORK, MAY HAVE AIR PROBLEM SI NCE THERE'S A 3 IN GALVANIZED AIR LINE. SHAFT APPROX 12'D AT 75-DEG DIP, SUNK ALONG A DIKE (VERY ALTERED, FE-STAINING), NO SIGNS OF VEIN. HI-GRADE PILE SAMPLED. QTZ CONTAINED MINOR AMTS OF LIMONITE, CHALCOP RITE (?) AND CHRYSCOLLA. ACCESSIBILITY TO AREA VERY POOR, NEED A GOOD SIZE DEPOSIT TO PAY FOR ROADS INTO AREA. ; INFO.SRC : 3 FIELD OBSERV
