After World War II, administration of Chinkuashih's mining industry was taken over by the Nationalist government's Taiwan Gold and Copper Mining Bureau. In 1955, the bureau was reorganized as the Taiwan Metal Mining Company. That marked the start of an era when the Taiwan Metal Mining Company played a dominant role.
戰後，金瓜石礦業由國民政府設立的台灣金銅礦務局接手管理；1955 年改組為台灣金屬礦業公司，自此金瓜石礦業進入「台金時代」。
