Comment (Deposit): DEPOSIT IS IN HEAVILY IRON-STAINED GRANODIORITE, WITH SMALL ROOF PENDANTS OF HORNFELS AND ANDESITE DIKES. GRANODIORITE IS SHATTERED AND BRECCIATED IN VICINITY OF NE-TRENDING FAULT ZONE. MINERALIZED ROCKS ARE MOSTLY ALTERED GRANODIORITE CONTAINING NUMEROUS SULFIDE-BEARING THIN QUARTZ VEINS, DISSEMINATED SULFIDES, AND MINERALIZED FRACTURE COATINGS. ORE MINERALS ARE ASSOCIATED WITH PYRITE AND PYRRHOTITE AND INCLUDE CHALCOPYRITE, MOLYBDENITE, MALACHITE, AND MINOR MOLYBDITE, SPHALERITE, AND GALENA.
