The Lagina brothers and their team continue their relentless quest for treasure in The Curse of Oak Island Season 12, Episode 15.

In the previous episode, Sinking In, the team made significant progress at the Money Pit, where their excavation of the TB1 shaft reached a depth of over 100 feet.

Their efforts unearthed wooden timbers and a wooden dowel, hinting at a tunnel structure from the original Money Pit dig.
