The lucy l. company has upon the same property a monster copper vein. it has been developed to the depth of five hundred feet and is two hundred and fifty feet in width. the ore is mostly a sulphide.
Assays from the veins of the lucy l. mine, from miscellaneous samples, run from 1.34 to 33,365.00 gold from seven to forty-seven ounces silver from twenty to sixty-eight per cent, bismuth from two to twenty-seven per cent, cop-per from sixteen to thirty-eight per cent, lead tin, one and sixty-five hundredths per cent nickel, sixty-five hundredths per cent.
