Underground Mining on the Mesabi Range Minnesota DNR

Underground mining of natural iron ore deposits occurred on the Mesabi Range in northeastern Minnesota from 1892 to 1961. The Mesabi Range is the ledge rock exposure of the Biwabik Iron Formation, a geological feature that stretches in length for just over 100 miles, from west of Grand Rapids in Itasca County to east of Babbitt near the St. Louis / Lake County line.

iron III - Michigan State University

On the Menominee range, ore bodies formed in troughs created by folded sedimentary layers. Impervious shales form the bottom of the ore bodies. Many of these ore bodies do not extend to the surface and thus the iron-formations are sufficiently deformed so that it was necessary to utilize underground mining methods rather than the large open-pit ...
