Location: The California mine is located in NE1/4 sec. 9, T. 10 S., R. 6 W., Fairbanks Meridian. The exact location of this mine is uncertain, but it is in the canyon of California Creek, near the mouth of Elsie Creek. This prospect is included in locality 41 of Cobb (1972 [MF 410]).
Geology: The California lode mine contains small veins of complex ore in schist. The most valuable component of the ore is silver; however, it also contains some gold, considerable copper, and a little lead (Smith, 1936, p. 24). Ore minerals include a lead-antimony sulfide (probably jamesonite), bismuthinite, arsenopyrite, pyrite, stibnite, chalcopyrite, and argentiferous galena (Joesting, 1943 [ATDM Pamph. 2]; White and others, 1952). Ore samples assayed 0.27 ounces of gold per ton and 259 ounces of silver per ton; one sample contained 600 ounces of silver per ton (Joesting, 1943 [ATDM Pamph. 2]). A few carloads of ore were said to have been produced (Wedow and others, 1952).
Workings: Little is known about this mine.
Production: A few carloads of ore were said to have been produced (Wedow and others, 1952).
