Big Thunder Gold Mine, formerly known as the Gold Hill Lode, dates back to the 1880s, when two German immigrants teamed up to try their luck and intercept the Lucky Boy vein. While the big gold vein hasn’t been found yet, Big Thunder Gold Mine still holds potential for gold mining and explorations are ongoing. Meanwhile, visitors can enjoy touring one of the safest mines in the Black Hills and learn about historic mining. Gold panning is even available for those who really want to get a taste of gold mining.

In addition to tours and panning, the Mining Museum at Big Thunder Gold Mine is a free attraction, with historic mining equipment (the largest collection in the Black Hills) and educated guides.
