The Curse of Oak Island

Tonight on The Curse of Oak Island...

That is an unusual find.

But you see on the top right?

Yeah. Didn't we get those

crazy roman numerals on the U-shaped structure, too?

I got seven and a half foot of tunnel.

Yeah, it's nice, eh?

You don't build a tunnel

like this unless you're moving something important.

Yep.

We want to take a look

down in that cavity.

Here we go.

Slowly.

Whoa.

There is an island in the North Atlantic

where people have been looking for

an incredible treasure for more than 200 years.

So far, they have found a stone slab

with strange symbols carved into it...

...man-made workings that date to medieval times,

and a lead cross whose origin may be connected

to the Knights Templar.

To date, six men have died

trying to solve the mystery.

And according to legend, one more will have to die

before the treasure can be found.

Hey, guys. Hey.

Hey, guys.

-How you guys doing? -Oh, Peter...

With the dawn of another morning

on Oak Island comes renewed hope

for brothers Rick and Marty Lagina and their team

that they will finally make the ultimate discovery

and solve the 228-year-old treasure mystery.

So, uh, what are we doing?

We're pulling the casing right now from the previous hole,

D.5n-25.5.

Right now we still have some gaps in the data,

so we wanted to move the rig another five feet

and we're gonna drill D.5N-24.5

and see if we can repeat

-and hit the tunnel again. -Okay.

Today they are drilling Borehole D5N-24.5,

located some 28 feet east

of the mid-18th century structure

known as the Garden Shaft.

It is the team's hope

that they will once again penetrate a mysterious tunnel

that is believed to run directly westward

below the shaft and into an area

that has been dubbed the Baby Blob.

Over the past year,

high-trace evidence of precious metals

has been detected throughout this region,

as well as directly beneath the Garden Shaft.

However, one week ago...

There's our wood.

There's our tunnel right there.

...after once again encountering this tunnel

more than 30 feet to the east of the Garden Shaft,

the team detected additional evidence

of precious metals on a wood sample.

This means that the treasure could actually lie buried

anywhere throughout the entire region.

If we hit it a third time

on the east side of the Garden Shaft,

I think that's probably enough to confirm

that this is our tunnel.

-Mm-hmm. And we're still waiting on dating

-to come back on the wood from this side as well. -Yeah.

We want to verify that this is real,

because if it is, this is a reason to get excited.

-Right. -Mm-hmm.

Now it is the team's goal

to not only continue tracking the mysterious tunnel

in the direction of the Garden Shaft

and the Baby Blob but perhaps

also make direct contact

with the ultimate source of the precious metals.

Once Dumas starts to work in the shaft

and they deepen that shaft, if they confirm

the tunnel below is there, we can do some lateral drilling

down the length of that tunnel as well.

-Yeah. -That's the way to do it.

Absolutely.

We have to move things around,

but hopefully the treasure will be found

partially because of it.

Currently, Rick, Marty and the team

are awaiting permission from the provincial government

to allow a mining company named Dumas Contracting Limited

to extend the Garden Shaft to a total depth of 98 feet.

This will not only help the team find out

if the legendary treasure

lies directly below the structure

but also allow them to construct lateral tunnels

toward any other promising targets.

We have almost singularly focused on

the Garden Shaft extension

and the possible tunneling associated with it.

Hopefully, we intercept the tunnel that we know

is beneath the Garden Shaft with this borehole.

Then, once Dumas arrives,

we have the opportunity to tunnel,

which we hope will get us closer to the treasure.

Gotcha.

All right. Here we go.

-Okay. I like this hole.

I think she's going in.

If we have enough data

to suggest that this is the continuous tunnel

that goes under the Garden Shaft,

the second phase of this is to get a sonar or camera down.

Yeah, it'd be great to get a camera in there

and see where it's going.

Perhaps this could lead to something,

and that's why we got to track this down.

-Yeah. Yeah.

Hopefully we're getting closer.

While the drilling operation continues

in the Money Pit area...

Hello, guys. I'm on the edge of my seat.

-Hey, Marty. -Hey.

...Alex Lagina has

joined his father Marty

and Uncle Rick, along with other members of the team,

for a highly anticipated meeting in the war room.

We have C-14 results

from wood retrieved as part of

the sonic drill program above the Money Pit,

which, again, is closely associated

with the tunnels that we have found.

Marty and Rick's business partner Craig Tester

has just received a carbon-dating report

on a wood sample from Borehole D5N-26.5,

the borehole that encountered the mysterious tunnel

on the eastern side of the Garden Shaft one week ago

and which also contained trace evidence of precious metals.

We're hoping that this data will confirm

pre-searcher activity in that area.

So, I'm going to turn it over to Craig,

and hopefully he's got good news for us all.

Okay. So, this is where the tunnel

is going to the west, going to the Garden Shaft, really.

And then the piece we took,

we felt was the outer edge,

which would be the date it was cut down.

The numbers come back

55.6% from 1735 to 1804.

Whoa.

That's good.

24.7%, 1656 to 1684.

So, the unknown tunnel almost has to be depositor,

it's not a searcher.

Correct.

Wow.

Actually, those date ranges brings up a theory to me,

the Duc d'Anville expedition in 1746

that tried to recapture Louisbourg.

So, it's-- that certainly falls in that range.

Yeah. Correct.

I agree.

I found eight pages

of a ship's log.

In 2017,

Oak Island historian Doug Crowell discovered

a portion of a French naval report

in the provincial archives

related to the unsuccessful attempt by France

to reclaim Nova Scotia from Great Britain in 1746.

According to the ship's log, prior to the French defeat,

a secret operation to hide a vast cache of valuables

had taken place somewhere south of Halifax.

"September 8th.

"It has been agreed that a deep pit be dug

"and treasure securely buried.

"The pit to have a secret entrance

by a tunnel from the shore."

It was carried out under the command of the Duc d'Anville,

a prominent member of the Rochefoucauld family,

who are believed to have connections

to the Order of the Knights Templar

dating back to the 12th century.

In my mind, there's no doubt that they're

pointing right to Oak Island.

Those dates are highly significant to me.

This is an outlier in the sense that it's much more definitive

than almost everything we get.

Mm-hmm. -Absolutely.

Is it possible

that the team has now confirmed

that the tunnel running below the Garden Shaft,

which has also been scientifically dated

to as early as 1735,

may very well be related to the ship's log

that Doug Crowell found in the Nova Scotia Archives?

If so, could they have finally discovered the key

to solving the Oak Island mystery?

Here we have a very specific piece of data,
