Detects Vibrations from Steel Caissons in Money Pit | The Curse of Oak Island

The twelfth season of The Curse of Oak Island continues to captivate audiences, and Episode 13 takes the legendary treasure hunt to thrilling new depths. The Lagina brothers and their dedicated team have embarked on an ambitious excavation in The Money Pit, deploying massive steel casing in their attempt to reach the fabled Chapel Vault. Meanwhile, intriguing discoveries on Lot 5 and in the swamp provide new connections to historical treasure deposits. Could this be the moment that changes everything?

Deep Dive into The Money Pit

The highlight of the episode revolved around the team’s determined effort to drill deep into The Money Pit, targeting the long-rumored Chapel Vault. First encountered in 1897 by treasure hunter Frederick Blair and driller William Chappell at a depth of 153 feet, the vault was described as a seven-foot-high, concrete-encased chamber possibly holding gold, artifacts, or vital clues.

After months of meticulous analysis of core drilling results and groundwater samples, the team found signs of man-made structures and traces of precious metals underground. With these promising indicators, they enlisted the expertise of Vanessa Lucido from ROC Equipment to deploy a massive seven-foot-wide steel casing. The plan was to bore down over 200 feet if necessary, overcoming obstacles that had thwarted previous searchers.

As the first casing, ceremonially named True Believer, began its descent, anticipation was high. The team struck wood at 87 feet—some bearing axe marks—suggesting an old underground structure. Then, at 91 feet, they unearthed a massive wrought-iron spike, possibly from an early treasure hunting expedition or even part of the original Money Pit defenses. As they dug deeper, they awaited further clues that could validate the Chapel Vault’s existence.

Shocking Discovery on Lot 5

While The Money Pit excavation progressed, another shocking discovery unfolded on Lot 5, an area that has produced significant artifacts in the past. Jack Begley, archaeologist Fiona Steel, and assistant Todd Langth stumbled upon a dazzling object buried in the soil—an apparent gemstone or diamond-like artifact. At first glance, the discovery hinted at immense historical and monetary value, raising the possibility that a figure of great wealth had once been on Oak Island.

However, lab analysis by archaeologist Laird Niven and archaeometallurgist Emma Culligan revealed that the diamond was actually a high-content paste jewel—an artificial gemstone popular in the early 18th century, particularly in France. Despite not being a real diamond, the artifact was still significant. The craftsmanship and era of the jewel aligned with the 1746 expedition of French Admiral Duc d’Anville, rumored to have hidden treasure deposits in Nova Scotia. This discovery supported theories that Lot 5 may have served as a staging ground for treasure concealment efforts centuries ago.

Uncovering Secrets in the Swamp

Meanwhile, in the northern part of the swamp, Rick Lagina, Alex Lagina, and geoscientist Dr. Ian Spooner investigated a newly exposed wooden structure at a depth of three feet, accompanied by stacked rocks. The find bore a striking resemblance to previously discovered cobblestone pathways and a slate vault, both of which hinted at man-made engineering dating back hundreds of years.

Dr. Spooner analyzed the site and determined that the structure was likely built for cargo transport. If true, this could be a game-changer. For years, theories have suggested that Oak Island’s swamp was artificially created to hide treasure or facilitate secretive operations. Could this discovery point to long-lost transportation routes used to move treasure from ships to underground caches? While definitive proof remains elusive, the team is more motivated than ever to continue digging into the swamp’s enigmatic past.

Historical Clues and Artifacts Emerge

In addition to discoveries in The Money Pit, Lot 5, and the swamp, another clue emerged from a previously recovered artifact. A hand-forged iron spike, found on Lot 1 near a boulder referenced in Blair’s treasure map, was examined by blacksmithing expert Carmen Leg. He dated the artifact to the early to mid-1700s and theorized it may have been used to anchor a boulder in place—possibly as part of a treasure-marking system.

This theory coincided with speculation surrounding Duc d’Anville’s failed Nova Scotia campaign, which included plans to bury treasure in a secret pit connected by underground tunnels. However, not all experts agreed. Culligan suggested a later date for the artifact, possibly the late 1700s. This debate underscored the ongoing challenge of interpreting Oak Island’s mysterious relics and deciphering their true origins.

Final Push Towards the Chapel Vault

As the casing continued to dig deeper into The Money Pit, the team employed a wash plant, overseen by Rick Lagina, Scott Barlow, and Billy Gerhardt, to sift through the spoils. Among the discoveries was a heavy square metal fragment with signs of advanced craftsmanship. While its purpose and age remain uncertain, its presence reinforced the belief that something significant might be buried deep within The Money Pit. Could it be part of the Chapel Vault’s defenses or merely another remnant from previous treasure hunters?

What’s Next for the Oak Island Team?

With so many discoveries in Episode 13—from the mysterious gemstone on Lot 5 to the unexplained wooden structure in the swamp—the Lagina brothers and their team are at a crucial turning point. The massive excavation in The Money Pit has yielded promising clues, but the ultimate prize, the Chapel Vault, remains just out of reach.

As the season progresses, the team will undoubtedly push forward with more excavations, testing, and historical research. The recent discoveries reinforce long-held theories that Oak Island was used as a secretive site for treasure concealment, potentially linked to historical figures such as the Knights Templar, French naval officers, or wealthy privateers.

However, Oak Island has a history of leading treasure hunters down promising paths, only to end in frustrating dead ends. Will The Curse of Oak Island finally break this cycle, or will the mystery remain unsolved for yet another season? The team remains relentless in their pursuit, determined to uncover the truth behind Oak Island’s centuries-old enigma.

Will their perseverance finally pay off? Only time will tell.
