Comments on the geologic information

  • Geologic Description = Gold is found in numerous, nearly vertical quartz veinlets striking S. 20-60 E.; they contain pyrite and arsenopyrite (Mertie, 1918). Some of these veins contain up to 0.58 ounces of gold per ton (Mertie, 1918). The quartz veinlets are cut by calcite veins carrying some gold and sulfides (Mertie, 1918). Contiguous mineralized zones are up to 36 inches wide in altered dolomite-calcite-quartz-sulfide rock (Foster and Chapman, 1967). Small pits expose chromite in serpentinite, and a stibnite vein was uncovered in a placer cut (Joesting, 1942, ATDM Pamph. 1; Mertie, 1918).
