    Virginia Geological Survey Barite

    The Hopkins, Earl, and Ringstaff mines were the greatest producers in this county. Extensive mine shafts (reaching a depth of 50 feet) and connecting tunnels were built through Beekmantown dolomite at the Hopkins mine where 234 tons of barite was extracted during a six-month period in 1904. The Earl mine is a 250 foot-long, 20 foot-deep open cut.

    Geology And Mining History Of The Southeast Missouri

    By the 1860s barite was recovered from the residuum by hand mining, also resulting in widespread diggings, but generally not underground mines in bedrock. Mechanized open-pit mining of the residuum for barite began in the 1920s. Barite production slowed by the 1980s, and there has not been any barite mining since 1998.
