Originally mined for silver - Japan's first recorded silver production was from here in 699 A.D. Later a Pb-Zn-Ag mine. (1958 production = 13.0 tons Ag.) Hydrothermal veins in fissures in highly altered Miocene quartz porphyry, and disseminated in surrounding country rock. Metal mining has now ceased, but the surrounding altered country rock is mined for high-quality clay for porcelain and refractories. (The "kaolin" here is actually halloysite.) Remaining sulphides are detrimental to the clay ore and must be removed.
