The St. John Mine is located in Potosi, Wisconsin. It was added to the National Register of Historic Places in 1979. [1]
Once a natural cave, Native Americans mined lead out of the site before Wisconsin's "lead rush" in 1827. [2] The first non-Native American work the mine was Willis St. John. The mine is privately owned and tours are no longer available. [3] [4]
