The Curse of Oak Island Season 12, Episode 15 preview: The team teases finding the treasure vault
The Lagina brothers and their team press on in The Curse of Oak Island Season 12, Episode 15.
In Sinking In, their TB1 shaft excavation at the Money Pit surpassed 100 feet, revealing wooden timbers and a dowel—possible remnants of an original tunnel. However, an unexpected collapse halted progress, requiring stabilization.
Meanwhile, on Lot 5, Gary Drayton unearthed copper nails near a circular stone foundation, later identified as ship-related from 1720–1760, supporting theories of early maritime activity.
With new leads in the swamp and fresh drilling at the Money Pit, could the team be closing in on the legendary treasure vault?
Gary Drayton finds a gemstone in the swamp that is pre-searcher
In the forthcoming episode, the team focuses on the swamp, a location long shrouded in mystery. Recent investigations have unveiled new pathways, suggesting a higher level of historical activity than previously believed.
Metal detection expert Gary Drayton announces, “I got a signal,” leading to the unearthing of an artifact. Emma Culligan examines the find, estimating its age to be from the mid to late 1700s.
Marty Lagina reacts with intrigue, stating, “That could be pre-searcher. ” This reinforces the idea that someone of significant status may have been on the island long before modern treasure hunters, which Culligan agrees with.
Jack Begley further theorizes that “some prominent person was on Oak Island pre-Money Pit,” suggesting the island may have more treasure than previously believed.
Breakthrough at the Money Pit: Could it be the treasure vault?
Meanwhile, at the Money Pit, the drilling team experiences a moment of suspense when Alex Lagina notes, “We could have just pierced the tunnel or chamber.”
This statement electrifies the team, as they have long suspected an underground vault or hidden passage exists within the Money Pit area.
Marty Lagina raises the stakes by speculating, “It could be a treasure vault,” sending waves of excitement through the crew.
Rick Lagina is visibly stunned, suggesting a major discovery could be imminent.
With the drilling process yielding increasingly promising results, the team now faces one of its biggest questions yet: Are they finally on the verge of finding the treasure they’ve been searching for?
