Wisconsin Moonstone LLC, in Stettin, is hoping to bring a similar mining experience to the state, with a modern twist. After signing up online, amateur miners only need to bring themselves, as Wisconsin Moonstone LLC provides all the necessary materials for their dig. “Everybody knows what to do once you get here,” Wisconsin Moonstone LLC co-owner Emi Oshim said. That’s a big reason why Wisconsin Moonstone LLC has become so attractive to rock enthusiasts from all over. Moonstone LLC is closed for the season, but plans on opening back up on June 1, 2026.
