| Deposit | VEINS NORMALLY 4-12 FT THICK BUT UP TO 40 FT. THERE ARE THREE TYPES OF VEINS: (1) MAGNETITE AND MINOR PYRITE AND MINOR CALCITE AND MINOR CHALCOPYRITE WITH 30-67% FE; (2) MAGNETITE AND ENRICHED CHALCOPYRITE IN BRECCIA ZONES; (3) CU AND FE DEPOSITS IN ALTERED SEDIMENTS NEAR PORPHYRY MARGIN. HIGH GRADE CHALCOPYRITE-BORNITE-COBALT MINERALS IN SMALL LENSES IN LIMESTONE. ESSEX VEIN: LIMESTONE ON N. WALL THIN DIKE OF NEWCASTLE PORPHYRY ON S. WALL (VEIN STRIKES E-W) WITH SKARN BETWEEN PORPHYRY AND A LARGE MASS OF PORPHYRY (LOOKS LIKE A PENDANT TO NJP). EAST BOXSHAW VEIN: FAULTED IRON VEIN IN PORPHYRY, BOXSHAW HILL IS APPARENTLY THE SAME. ORCHARD HILL VEIN: MAGNETITE VEIN BETWEEN SHALE AND ALTERED PORPHYRY. SPANISH VIEW: IN LIMESTONE. WEST WATER TANK VEIN: MAGNETITE VEIN IN LIMESTONE WITH SKARN TO SOUTH. EAST WATER TANK VEIN: MAGNETITE VEIN WITH LIMESTONE TO NORTH AND NEWCASTLE PORPHYRY TO SOUTH. PORPHYRY IS ALSO MINERALIZED WITH 0.5% CU OVER WIDTHS VARIED BETWEEN 50 AND 200 FT. |
