In the epic 12th season of The HISTORY Channel's hit series "The Curse of Oak Island," Rick and Marty Lagina are back, alongside their talented team, and closer than ever to solving the 229-year-old treasure mystery of Oak Island. Using cutting edge technology, the team pinpoints evidence of a large source of precious metals deep within the Money Pit area, and executes a core-drilling operation to zero in on the legendary valuables already discovered during large-scale excavations. Additionally, new discoveries will shed light on the treasure mystery and new secrets will be revealed, corroborating the team's suspicion that Oak Island has been visited numerous times by medieval European cultures and may contain multiple treasures.
