A Dam in the Deep: Stunning Underwater Discoveries Rock Oak Island

“I can’t wait to get my eyes on it.” With those words, diver Tony Sampson plunged into the cold waters just north of Oak Island—and what he uncovered may rewrite the very story of the island’s mysterious swamp.

In a bold new search effort, Alex Lagina and Jack Begley teamed up with Sampson and underwater imaging expert Ken Deber. Their target? A potential man-made dam thought to lie near the northern reaches of the swamp—an area believed to have once been dry land centuries ago. With high-tech sonar, metal detectors, and an ROV camera, the team set out to find evidence that could finally connect Fred Nolan’s long-suspected beach structure with Zena Halpern’s controversial map.

“This is awesome. Let’s get started.”

Eyes in the Deep

As Tony descended into the murky waters, Ken operated the ROV from the surface, sweeping the seabed in a tight grid, keeping visual contact with the diver. It didn’t take long before excitement began to ripple through the team.

“He’s fanning. He’s on something now.”

Though provincial law prohibited the team from removing artifacts, Tony’s careful scanning soon revealed promising clues: possible hand-carved wood, old timbers—and then, something glimmered.

“Look guys, we’ve actually got some pottery down here with blue markings.”

Could these artifacts be connected to the 17th-century finds recently unearthed on Lot 5? The similarities were striking. The presence of blue-decorated pottery, pipe stems, and even a mysterious disc-shaped object hinted at something much larger lurking beneath the waves.

A Coin with a Hole in History

Then came the moment that brought the team to its feet. Tony discovered what appeared to be a coin—with a hole in the center. It bore a striking resemblance to a Chinese coin found by Gary Drayton and Jack Lagina on Lot 15 in 2020—an artifact dated to over a thousand years ago.

“I thought it was one of those Chinese-style coins… and that dated back to possibly B.C.”

If confirmed, this could mark a major historical breakthrough: further evidence of global visitors to Oak Island long before modern European explorers—and a potential link to the creation of the man-made swamp.

Although the team couldn’t retrieve the item without a permit, the excitement was undeniable.

“One thing I know for sure: there’s a concentration of artifacts underwater.”

The Garden Shaft: Digging Toward the Unknown

While the dive team was uncovering submerged mysteries, Rick and Marty Lagina turned their attention to the Garden Shaft—a refurbished 18th-century structure now descending toward 100 feet. Their mission: to reach a 7-foot-tall tunnel discovered during earlier core drilling, believed to date back as far as the 1600s.

But progress was met with a familiar foe: water.

“200 years. Water has always been the problem.”

To combat the relentless seepage, the Dumas crew used high-pressure urethane foam to seal the leaks—one set at a time. As Rick and Marty descended into the shaft themselves, they stood mere feet away from potentially breaching the centuries-old tunnel.

“We’re looking at dirt no one’s ever seen before.”

Into Aladdin’s Cave

Meanwhile, another groundbreaking effort was underway in borehole KL14.5. Geologist Terry Matheson and archaeologist Moya MacDonald supervised the camera drop into a massive void nicknamed “Aladdin’s Cave”—an open underground space nearly 150 feet deep.

“That’s big. That’s bigger than anything we’ve seen.”

As the high-definition camera entered the chamber, it revealed swirling silt, strange shadows—and what might be a square-headed bolt. The possibility of man-made objects within the cave sparked a new wave of excitement and speculation.

“We’re in the cave… this could be a treasure location.”

Plans were quickly made to return with sonar mapping to chart every crevice of the hidden chamber.

Back to C1: A Glint of Gold?

As the sun dipped below the horizon, diver Mike Huntley descended into the C1 shaft—more than 170 feet deep—armed with an underwater metal detector. His goal: locate the gold-colored object previously spotted on video.

“I hear something.”

The metal detector pulsed with life. This was no false reading—Mike was well away from his stainless steel helmet. The hit came from the cavity below, near the rubble pile.

“That’s a game changer.”

If verified, the metal detected deep underground—within a natural solution cavity—would defy explanation. It would strongly suggest human activity and potentially, the very treasure the Laginas have sought for over a decade.

A Convergence of Clues

This episode marked a crescendo of discoveries: artifacts in the sea, ancient coins, man-made bolts underground, and tantalizing hits of metal deep within the Earth. From the muddy swamp edge to 150 feet below the island, the clues are converging.

What lies beneath Oak Island may finally be revealing itself—not through a single discovery, but through a growing web of evidence pointing to one undeniable truth:

Something was buried here. And someone went to extraordinary lengths to hide it.
