Land Status

Land ownership: Private
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments

Comment (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..

Comment (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

Comment (Exploration): SEVERAL OTHER LARGE GEOPHYSICAL AND GEOCHEMICAL ANOMALIES OCCUR SOUTHEAST AND SOUTHWEST OF THE MAIN ZONE. EXTENSIVE DRILLING HAS BEE COMPLETED WITH AT LEAST 10,000 FT OF DIAMOND DRILLING COMPLETED.

Comment (Workings): 157 FOOT SHAFT WITH 102 FT OF DRIFTS AT THE 80 FT LEVEL AND 260 FT OF DRIFTS ON THE 130 FT LEVEL AS WELL AS SEVERAL LARGE STOPES.
