The Upper Mississippi Valley Zinc-Lead District is the classic Mississippi Valley Type deposit. The first workings by Europeans settlers date back to 1685, with the deposits known to Native Americans back into antiquity. The last mines closed in 1978, thus mining in the area spans nearly 300 years, with peak production between 1917-1952. An estimated 1.2 million tons of zinc and 100,000 tons of lead were produced. There were thousands of small to large mines, prospects and âdiggingsâ in the County. Wisconsinâs state mascot, the badger, refers to the scruffy appearance of lead miners emerging from their small mines. Many of these mines have now been covered or reclaimed.
The mineralization was largely confined to Middle Ordovician limestone and dolostone of the Galena, Decorah and Platteville Formations. The deposits are thought to be the result of movement of low temperature (90 to 150 degrees C) connate brines out of adjacent basins due to stress imposed further east due to the rise of the Appalachians. Local ore controls were fracture zones, solution collapse structures (âpitches and flatsâ) and subtle folds.
The mineralogy was relatively simple, but coarsely crystallized specimens were common. The main ore minerals were galena (Wisconsinâs official state mineral), sphalerite, smithsonite and, to a lesser extent, baryte and copper sulfides. Notable accessories are calcite, dolomite, marcasite and pyrite. The abundant marcasite is notoriously prone to deterioration, destroying many fine samples. This makes large stable samples relatively scarce and probably is the reason why specimens from this district are less well represented in collections. The best known materials, from a collector point of view, is calcite which forms fine scepter crystals with rhombohedrons gowning on steep scalenohedral bases.

The upper Mississippi Valley zinc-lead district, comprising an area of about 4,000 square miles, includes the southwest part of Wisconsin, the northwest corr.er of Illinois, and a narrow fringe of the northeast edge of Iowa along the west bank of the Mississippi river. Lead and zinc deposits occur throughout the entire area, but recent production of ore has been limited to about 650 square miles in a belt extending north and south through the central part of the district. Discoveries of ore bodies since 1942 have considerably enlarged this productive area. Small isolated deposits of lead, copper, and zinc are on all sides of the maul district, indicating that the total area of mineralization is considerably larger than the actual mining district.
