Chichibu mine

Located in western Saitama Prefecture, west of Chichibu City. This mine contains two ore bodies: the Doshinkubo and the Hashikakezawa.

This district produced the first copper mined in Japan, in the year 707 C.E., early in the reign of Empress Gemmei.

Boyuan Zhang, caption of https://www.mindat.org/photo-1480561.html :

"Chichibu Mine was initially discovered in 1610 as a placer gold deposit and later developed into a multi-ore complex. Large-scale mining began in 1910, and by the 1940s, it became Japan's second-largest iron mine, employing 1,060 workers at its peak. Metal mining ceased in 1978, transitioning to limestone extraction until the mine's permanent closure in September 2022."
