The Curse of Oak Island

Tonight on The Curse of Oak Island...

-What the hell have you got there? -A big chunk of steel.

That could be the drill that found

the famous Chappell Vault.

Like a small jewelry chest or something.

Which means it could've been

part of any treasure that was here.

Look at that. A coin.

-What? -Cool.

Wow.

-There's a boulder. -It looks similar to

-the stone roadway. -Yeah.

This could be very important.

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, Roger. -Hey, how's it going, Alex?

-Good. Good to see you again. -Nice to see you.

So, what's the update? What's going on?

Well, we're finally moving ahead now.

Good.

As a new week begins on Oak Island,

brothers Rick and Marty Lagina and their team

have good reason to believe

that they are on course to finally solve

a 229-year-old mystery.

We've pretty well dealt with all that water situation

-we were dealing with. -Mm-hmm.

It's all stabilized.

The geofoam is in and it went well?

Yeah, it was amazing. It was amazing.

And now we've got

-full control of the water. -Good.

-All right, here we go. -Let's do this.

Five weeks ago, the Oak Island team's efforts

to deepen the early 18th-century Garden Shaft

down to a target depth of 95 feet

were halted when mysterious voids

outside of the structure

caused it to flood with salt water.

This is where our water starts, right here.

And then it comes in along the side.

This made the team wonder if they had encountered

one of the legendary flood tunnels

which have thwarted searchers in this area

for more than two centuries.

Especially since a seven-foot-high tunnel

was recently discovered just below the Garden Shaft

which leads toward the Baby Blob,

an area where water testing has revealed

high trace evidence of gold and silver

between 80 and 120 feet underground.

Tell us what we're going to do.

Well, we're going to pump some foam in her

and try to get your voids filled up.

But, thankfully, last week,

representatives from Minova Global began applying

an industrial compound known as geofoam

to fill the voids, stop the flow of water

and stabilize the shaft

so that Dumas Contracting Limited

can continue deepening the structure

over the course of the next several weeks

and finally reach the possible treasure tunnel below.

Now, if we can get into this tunnel,

and if the tunnel's original works,

then it probably leads to something good,

so we could be close.

We're going to geofoam everything nice and tight,

and then after that, we're going to excavate,

install a panel, excavate, install a second panel,

-excavate. -Okay, so it's basically

digging again?

-Digging again. -I see you've got the grab on.

Exactly. We just started digging,

so we'll be very close to that 89-foot depth.

At 89 feet, we're getting close

to that 95-foot tunnel.

But I'm really excited to get down to depth

and see what's down there.

Oh, absolutely. For sure. For sure.

The last two or three days have been, you know,

upbeat because the guys were finally moving ahead.

-Right. -Getting away from this water, so yeah.

Right. Perfect. Well, thank you, Roger.

-Sounds good, man. -I'll let you get back to it.

-Absolutely. -Thanks.

Talk to you later.

Later that afternoon,

as Dumas continues their work in the Garden Shaft,

nearly 73 feet to the southwest...

-Hey, Marty. -What's going on here?

So what we're doing here, Marty,

this hole is about five feet southwest of H-8.

...Marty Lagina joins

Oak Island historian Charles Barkhouse,

geologist Terry Matheson,

and surveyor Steve Guptill

as they supervise the drilling

of borehole I.25-6.25.

A borehole that, incredibly,

may be on track to locate

a second potential treasure deposit

in the Money Pit area

more than 180 feet underground.

The plug that fell out of the H-8 caisson,

that could've fallen in this direction.

Okay.

Mike, what's up?

I hit the void at 183.

All right, so let's see what we got.

One week ago, while drilling

borehole K-6, just eight feet to the south,

the team penetrated a mysterious void

at a depth of 183 feet.

It is a potentially critical discovery

because the void is adjacent to borehole H-8,

which the Oak Island team excavated six years ago

with a 50-inch diameter caisson that they believe

may have come into contact with the fabled Chappell Vault

which was first reported by Frederick Blair

and his drill operator William Chappell in 1897.

During the team's excavation,

at a depth of nearly 180 feet,

they attempted to penetrate the possible vault,

and encountered a large void

which caused the spoils, or plug,

inside of the H-8 caisson to fall out,

resulting in the believed vault

being pushed deeper and somewhere off to the side.

-How deep are we? -Down 78 feet.

We got two more cores coming.

We're gonna take a look at those.

Now it is the team's hope

that with this new borehole, they can further explore

the void they discovered last week and hopefully

locate the long-lost Chappell Vault.

There's the top of the next run.

88 feet.

Okay, let's carve her up, guys.

-Excuse me, Steve-O. -Sorry, Terry.

No problem. Okay.

There's the top.

-So at some point-- -We got some wood here.

Charles, where do you think the wood came from?

It possibly could be the Chappell Shaft.

That's interesting.

We could be skimming along the outside edge.

The Chappell Shaft?

In 1931, Melbourne Chappell,

along with his father William

and Frederick Blair,

constructed a 12-foot by 14-foot shaft

down to a depth of 163 feet in order to locate the vault.

Unfortunately, they were unsuccessful.

But if the Oak Island team is correct that they have found

the outer edge of the Chappell Shaft...

could that offer an important clue

that they are in the general area

where the vault is located?

Okay.

Oh, whoa!

What the hell have you got there?

Big chunk of steel.

-There you go. -Whoa, Mike! What the heck?

This came out of the top of this sample right here.

-Yeah, really? -Really?

Yeah.

Could this be old-time drill pipe?

Because we know they drilled in these holes

and we know they used skinny pipe.

No question.

I think so, it's heavy enough.

That could be the drill that found

the famous Chappell Vault.

-Perhaps. -That could be it, right?

They used a skinny little drill.

Back in the 1890s, they did.

If we found something meaningful here

just below the Chappell Shaft,

we could put down another caisson.

If we see something worth getting...

we will get to it.

Well done, you guys.

Follow that pipe on down.

-Find the Chappell Vault. -All right.

Go get it.

While the operations continue

in the Money Pit area...

We're back.

It's time to get to work.
