| Deposit | BROAD DISSEMINATED COPPER SULFIDES ZONE FOLLOWS DUCTILE SHEAR ZONE. LOCALLY MINERALIZATION IS STOCKWORK. ALTERATION CONSISTS OF LOCAL INTENSE SILICA FLOODING, KSPAR AND BIOITITE POTASSIC ALTERATION SURROUNDED BY PROPYLITIC ALTERATION CONSISTING OF CHLORITE AND EPIDOTE. THE DEPOSITS HAS BEEN CHARACTERIZED AS A PROTEROZOIC PORPHYRY DEPOSIT. HOWEVER THE MAIN HOST IS NOT EXCLUSIVELY THE SHERMAN GRANITE. THE SHERMAN GRANITE PROVIDED THE HEAT AND FLUIDS BUT THE MINERALIZATION IS IN PART A REPLACEMENT OF THE COUNTRY ROCK, AN OLDER (1.7 B.Y.) DEFORMED GRANODIORITE. E-W TRENDING SHEAR ZONE THAT IS PERPENDICULAR TO THE CONTACT WITH THE COUNTRY ROCK GRANODIORITE AND THE SHERMAN BATHOLITH. THIS SHEAR FOCUSED HYDROTHERMAL FLUIDS AND CONTROLLED INTRUSION OF LATE STAGE FELSIC DIKES |
| Deposit | HOST ROCK FOLIATED GRANODIORITE IS PROBABLY BOULDER CREEK EQUIVALENT. ALTERATION AND MINERALIZATION WAS RELATED TO LATEST STAGES OF SHERMAN GRANITE BUT PREDATED THE EMPLACEMENT OF SPARSE PEGMATITES. MINERALIZED SHEAR ZONES IN THE COPPER KING DEPOSITS APPEAR TO HAVE DEVELOPED UNDER DUCTILE CONDITIONS. THE EAST WEST SHEAR ZONE AT THE DEPOSIT CHANNELED HIGH TEMPERATURE POTASH AND METAL RICH HYDROTHERMAL INTO THE COUNTRY ROCK. LATE STAGE SHERMAN FELSIC DIKES WERE ALSO MINERALIZED PLACING THE HYDROTHERMAL EVENT AT THE LATEST STAGES OF SHERMAN RELATED THERMAL ACTIVITY. MAGNETITE IS ABUNDANT IN THE MINERALIZED ZONE INDICATING HIGH TEMPERATURE RELATIVELY OXIDIZING CONDITIONS, MAGNETITE IS USUALLY ALTERED AT GRAIN BOUNDARIES TO MARTITIE (HEMATITE) INDICATING AN INCREASE IN OXIDATION POST DATED THE ORE FORMING EVENT.. |
