Comment (Production): CUMMULATIVE PRODUCTION FIGURES DERIVED FROM THE FOLLOWING YEARS: 1913 , 1916 , 1917 , 1919 , 1920 , 1922 , 1923 , 1925 , 1926 , 1947 AND 1948 . WHILE PRODUCTION OF SOME COPPER ORE WAS NOTED IN AN 1890 PUBLICATION, THE AMOUNT OF ORE PRODUCED WAS UNMENTIONED.

Comment (Development): TWO PATENTED CLAIMS, THE COPPER KING AND THE MASCOT

Comment (Deposit): AVERAGE OBSERVABLE WIDTH OF THE VEINS IS ABOUT 6 IN; HOWEVER IN THE UPPER ADIT, WHERE MINERALIZATION IS MOST INTENSE, VEIN WIDTH IS PROBABLY GREATER. MINERALIZATION DECREASES WITH DEPTH.

Comment (Workings): TWO ADIT LEVELS, ABOUT 130 FT APART VERTICALLY AND AN INTERMEDIATE LEVEL 60 FEET BELOW THE UPPER ADIT. LOWER ADIT IS AT AN ELEVATION OF ABOUT 2500 FT.
