| Deposit | COMPLEY MINERALIZED ZONE MORE THAN 120 FT WIDE IN THE LOWER CROSSCUT. OVERALL STRIKE OF THE ZONE ON THE SURFACE IS N 75 E. PYRITE, SPHALERITE AND GALENA ARE CONCENTRATED IN BANDS UP TO 6 FT WIDE. MOST BANDS STRIKE EAST. THE SOUTHERN AND CENTRAL PARTS OF THE VEIN ARE SEPARATED BY A QUARTZ PORPHYRY DIKE. VEIN IS BORDERED ON S BY STEEPLY DIPPING FAULT ZONE. N AND INTERMEDIATE VEINS ARE N OF DIKE, THE INTERMEDIATE VEIN CONTAINS TETRAHEDRITE, THE S VEIN CONTAINS CHALCOPYRITE AND IS S OF THE DIKE. |
