When the team returns to the island they find evidence of an underground tunnel and structure.

The team explores the possibility of getting a member of the crew underground to investigate if the gold traces comes from a network of tunnels.

The team is astonished when Gary unearths multiple artefacts in close proximity to the old ship's wharf and with the discovery of a shallower tunnel in the Money Pit, Marty's theory of an off-set chamber may finally be proven.

The discovery of mysterious ship logs provides more evidence that a 1746 French armada led by the Duc D'Anville landed on Oak Island; at the Money Pit, the team gets closer to getting a team member underground.

Gary unearths a curious artifact on Lot 8 and in the Money Pit; the team is astonished to discover that they may be chasing multiple tunnels towards the gold in the garden shaft.

The team returns to the swamp and immediately uncovers more evidence of a sunken ship; in the money pit, the discovery of a collapsed structure could mean they have finally located the off-set chamber.

The team's high hopes of finding the fabled treasure are intensified when they procure what could be the final piece of the puzzle.

The fellowship is stunned when evidence suggests that a dam lies buried at the end of the swamp, corroborating both Fred Nolan's theory, and Zena Halpern's Templar map.

While the archaeologists work hard to uncover a new feature discovered on Lot 5, the scientists have finally identified the area where the gold is.

While the team uncovers more evidence suggesting the mysterious man-made stone foundation on Lot 5 was purposefully hidden, the Fellowship is zeroing in on the gold in the Money Pit.

While the team searches for clues to understand why an ancient well was constructed on Lot 26, excitement abounds when more evidence of a tunnel heading directly towards the garden shaft is discovered.

As the Fellowship prepares to get a team member underground in the Money Pit for the first time, a new theory emerges suggesting that Nolan's Cross holds the secret to its exact location.

The team is ecstatic when new scientific evidence narrows down the location of the gold signature in the Money Pit. And Rick realises a lifelong dream when he finally gets underground on Oak Island.

Confidence grows when irrefutable, scientific evidence reports the fellowship is closer than ever to the gold.

The Fellowship is certain that they're closer than ever to an offset chamber when the probe drilling operation in the garden shaft finally gets underway.

As the garden shaft operation gets deeper, the evidence of gold becomes stronger.

While the drilling operation gets closer and closer to its destination, the team is shocked when they discover evidence of an ancient safe.

After a long wait, the Fellowship gets permission to return to their excavation in the swamp; almost immediately, they make a discovery that could connect all the cobblestone dots in the mysterious bog.

As time is running out, an exciting find in the swamp may have the fellowship rewriting the history of North America.

After a new find suggests that the Oak Island mystery could have ancient ties to Italy, the team investigates a stone structure that shockingly has a design that matches the original Money Pit treasure shaft.

The North Atlantic winter is quickly approaching but the stars are aligning for the fellowship of the dig when the swamp reveals more of its secrets, and a trip to Italy provides a shocking new insight into Nolan's cross.

While an incredible new discovery is made in the triangle-shaped swamp, Rick Lagina and members of the team make shocking connections in Italy between the Knights Templar and the Oak Island mystery.

Rick, Marty and the team make a discovery below the Garden Shaft that could be the key to solving the Oak Island mystery.

As new discoveries are uncovered in the triangle-shaped swamp and on Lot Five, the Oak Island team makes an incredible revelation in the Money Pit.
