Famous for its marvelous stibnite specimens, now found in museums around the world. The best specimens were found in the late 19th century, during peak productivity of the mine (16,600 tons Sb produced from 1875 to 1900). Closed in the 1950s. Locality labels for these specimens often under the obsolete name "Iyo province". The mine produced the antimony used in the bronze casting of the Great Buddha of Nara in 748 AD.
Simple stibnite-quartz veins cut across Cretaceous or Tertiary conglomerates and the underlying Sambagawa Belt schists and phyllites. The veins have been totally worked out, and it is hard to find even traces of stibnite here now.
