A shocking leak from The Curse of Oak Island Season 13 reveals that Rick and Marty Lagina may have discovered a 2,000-year-old metallic chamber beneath the Garden Shaft—potentially of Roman origin—an astonishing find that could rewrite history and finally uncover the truth behind the island’s greatest mystery.

A series of shocking leaks surrounding The Curse of Oak Island Season 13 have set off a firestorm among fans and historians alike.

If true, the Lagina brothers may have uncovered the most significant archaeological find in the show’s decade-long history — a sealed, metallic chamber buried beneath the infamous Garden Shaft that could link Oak Island’s mystery to ancient Rome itself.

According to production insiders who claim access to unreleased footage and sonar imaging data, the chamber was first detected late in the filming schedule during a deep drilling operation beneath the reconstructed shaft on Lot 8.

“When the scans came back, no one in the room said a word for almost a minute,” one crew member allegedly told a fan forum.

“It wasn’t wood or stone — it was something else entirely.

Something metallic, but far too old to be modern.”

Preliminary analysis of the sonar reflections reportedly revealed an almost perfect rectangular structure, approximately 15 by 10 feet in size, with smooth, reflective surfaces and what appear to be carved geometric symbols along the outer walls.

Metallurgical readings suggested the material might contain traces of tin, copper, and iron — a combination eerily similar to early Roman bronze alloys.

The supposed “Roman connection” has become the lightning rod of online speculation.

If confirmed, it would shatter centuries of accepted North American history.

“This could mean trans-Atlantic contact long before Columbus,” said one amateur historian on social media.

“The Romans could have reached Nova Scotia — and maybe even hidden something of immense importance here.”

Rick and Marty Lagina, the Michigan-born brothers who have spent more than a decade digging into Oak Island’s infamous Money Pit mystery, have remained unusually quiet since filming wrapped in late August 2025.

The History Channel has neither confirmed nor denied the leaks, but anonymous crew chatter suggests the discovery was deemed too “sensitive” to include in early promos.

“Rick looked pale when they first saw the chamber images,” a crew insider claimed.

“He just said, ‘This changes everything,’ and walked off.”

The Garden Shaft, the focal point of recent seasons, was originally believed to intersect with an early 19th-century search tunnel.

But over the past two years, new data from Dumas Mining’s excavation and scanning equipment revealed deeper anomalies that didn’t match any known shaft map.

The leak suggests Season 13 will begin with an expanded dig around this zone — culminating in the shocking sonar discovery near episode six.

What makes this leak so explosive is the alleged age of the chamber.

Some insiders claim samples taken from nearby material layers were dated to roughly 2,000 years ago — long before the first European settlers reached Nova Scotia.

“It’s not a treasure chest,” said another source familiar with post-production footage.

“It’s more like a vault — sealed tight, untouched for millennia.”

Online forums are already ablaze with theories.

Some fans argue it could be a hoax, perhaps planted debris from 18th-century excavators.

Others suggest the structure could be related to the Knights Templar, who have long been tied to Oak Island lore.

Yet a growing number believe the discovery finally connects the dots between ancient maritime civilizations and the mysterious engineering of Oak Island’s tunnels.

Adding fuel to the fire, several sharp-eyed viewers noticed that Marty Lagina was recently photographed outside a research facility in Halifax believed to house the chamber samples under analysis.

Meanwhile, Rick has not made a public appearance since early October, leading to rumors that the brothers have been placed under strict nondisclosure terms until the premiere airs.

If the leak is authentic, it could mark the most monumental turning point in the show’s history — and perhaps in the broader search for pre-Columbian trans-Atlantic contact.

Season 13 is expected to premiere in early 2026, and producers have hinted that “what lies beneath the Garden Shaft” will redefine everything fans thought they knew about Oak Island.

Until then, speculation will only grow.

As one online commenter summed it up: “If what they found is truly Roman… then Oak Island isn’t just a treasure hunt anymore — it’s a rewrite of history.”
