Subject category Comment text
Deposit MINERALICATION IS WITHIN THIN LIMONITIZED QUARTZITE AND SCHIST LAYERS AS COPPER-RICH POCKETS. DIKES OF TERTIARY GRANODIORITE PORPHYRY CROP OUT NEARBY AND COULD BE POSSIBLE SOURCE OF MINERALIZING FLUIDS. ALTERNATIVELY, DEPOSIT COULD BE A VOLCANOGENIC MASSIVE SULFIDE
