EXCITING DISCOVERY of Manmade Features (Season 12) | The Curse of Oak Island
Exciting Discoveries on Oak Island

A Week of High Expectations
Excitement runs high on Oak Island as brothers Rick and Marty Lagina, their partner Craig Tester, and their dedicated team uncover new man-made structures in the northern region of the triangle-shaped swamp. The team believes these findings could be key to solving the 230-year-old treasure mystery.
Uncovering a Stone Pathway and a Possible Vault
The latest excavation has revealed two significant structures: a stone pathway and what appears to be a small vault or cellar. Archaeologist Ian points out that the uniform rock distribution suggests a man-made structure rather than a natural formation.
The Anthony Graves Connection
In 1857, farmer Anthony Graves purchased a large portion of Oak Island and built his home near the swamp. While not actively involved in treasure hunts, rumors suggest he discovered a cache of Spanish silver coins on his land. Could this new vault be linked to his findings?
A Metal Discovery Beneath the Swamp
Using metal detectors, the team uncovers a mysterious iron object embedded in the swamp soil. As Gary Drayton carefully digs it out, they realize it has a brick fragment attached, suggesting it may have been part of a larger structure.
Exploring the Mysterious Structure
The following morning, Rick Lagina and Tom Nolan examine the newly discovered vault-like structure. Tom is astounded, noting that the cut slate and brickwork don’t resemble anything else previously found on the island. Could this structure have been built to hide something valuable?

A Handle from a Chest?
While searching the site, Rick and the team uncover a metal handle, which they suspect could have belonged to a treasure chest. If so, it may be connected to the Spanish coins that Graves reportedly found over 150 years ago.
Further Excavation Plans
Tom Nolan emphasizes the importance of excavating the entire structure to uncover any hidden artifacts. Rick assigns archaeologist Laird Niven to devise a detailed excavation plan to ensure the process is thorough and systematic.
Additional Finds: A Hook and a Crank
Later in the excavation, the team unearths a wrought iron hook, possibly dating back to the 1800s. The discovery raises questions: Did Graves build this vault to store his valuables, or was it created even earlier by unknown treasure hunters?
Lab Analysis of Artifacts
The following day, the team meets with archaeologist Laird Niven and archaeometallurgist Emma Culligan in the Oak Island lab to analyze the findings. The examination reveals:
- The hook dates to the early to mid-1800s, aligning with Graves’ time on the island.
- The pipe and crank handle appear to be from the late 1700s, predating Graves’ recorded ownership of the land.
A Possible Treasure Vault?
The discoveries suggest that this underground structure was built before Anthony Graves lived on the island. If so, who created it? And could more hidden treasures lie beneath?
Next Steps: Digging Deeper
The team agrees that further excavation in the swamp is essential. With growing evidence of hidden artifacts, Rick is convinced that Oak Island’s secrets are buried deeper than ever before.
