The Montreal and Cary mines closed in the 1960s when the steel industry changed from using high-grade iron ore from deep shaft mines to using abundant taconite ore that could be economically mined by the open-pit method. At the time of closing, the Montreal and Cary mines were producing ore from workings nearly one mile deep.
