Barry County Lead and zinc mining in Barry County occurred primarily in the 1880s through 1890s, with some production in the 1910s, 1930s and 1940s (IMOP database). There was likely unrecorded production in the 1930s. The primary lead and zinc mining area was the Purdy mines area, located east of the town of Purdy. The mines are hosted by limestones of the Mississippian Osagean Series.
