Excerpt from Mining and Milling of Lead and Zinc Ores in the Wisconsin District, Wisconsin The Wisconsin lead and zinc district includes not only mines in the State of Wisconsin, but also mines in those parts of Illinois and Iowa directly adjacent to southwestern Wisconsin. This district has long been known as a lead producer, but only within recent years has it been considered an important producer of zinc.
