The Cathey or Cathay district is in southwestern Mariposa County about 10 miles southwest of Mariposa and near the town of Catheys Valley.
The area was first placer-mined during the gold rush, and lode mining began in the 1850s. The principal mines were the Francis, Moore Hill, and Rich mines, which were last worked in the 1930s. A number of north-trending quartz veins up to 9 feet thick, in granodiorite and schist, contain native gold and sulfides. The sulfides, which include pyrite, arsenopyrite, and galena, sometimes are extremely abundant.
