- Missouri lead mining began in 1720 near Mine LaMotte after French explorers discovered galena. Lead mining helped to develop the state of Missouri by bringing settlers to the area, influencing the transportation infrastructure (including railroads and roadways), and creating an economic base for the state.
- Lead later was discovered northwest of Mine LaMotte in the Bonne Terre, Flat River and Desloge areas around 1864. Lead mining took place in this area, which is now dubbed The Old Lead Belt, until 1972.
- Exploration teams discovered the Viburnum Trend, or The New Lead Belt, in the 1950s. Lead mining began in the Viburnum Trend in the 1960s, and continues today.

Thanks to these efforts, Southeast Missouri, specifically the Viburnum Trend, has become synonymous with high purity lead. In fact, Missouri lead concentrates are used by smelters around the world to supplement lower quality lead concentrates.
Products created from Doe Run’s Missouri lead mining operations eventually benefit society through medical and nuclear protective shielding, start-up power for vehicles, back-up power for hospitals and telecommunications, and alternative energy storage for hybrid vehicles, wind and solar power.
