三治鉱山は山形県西村山郡西川町にあった鉱山。 金・銀・銅・亜鉛が採掘された。1966年閉山。 見立鉱山と一体的に運用され、堆積場などが残るらしい。
The Miya mine was a mine located in Nishikawa-machi, Nishimurayama-gun, Yamagata prefecture. Gold, silver, copper and zinc were mined. Closed mountain in 1966. It seems that it is operated integrally with the prospecting mine, and the sedimentary facility and others remain.
