Lost Louisiana Mine — Mulberry River Bluffs

Lost Treasure AR • Franklin County County
Description
Ozark legend of a lost Louisiana-operated silver or lead mine on bluffs above the Mulberry River near Cass — worked before the Civil War and never relocated after the war erased local memory of its entrance.
Historical Notes
Encyclopedia of Arkansas and regional mining lore describe a "Lost Louisiana Mine" in the Ouachita/Ozark foothills, often placed on steep Mulberry River bluffs near the former settlement of Cass in Franklin County. The story holds that pre-war miners from Louisiana shipped ore out secretly, then abandoned or sealed the workings during the Civil War. Later prospectors found slag and cut timbers but no main adit. Treasure hunters conflate the mine with buried payroll chests and Spanish workings, though historians treat the site as a lost mine legend rather than a documented producer.
