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,

i.e. probability window,

that could be associated with
the Duc d'Anville expedition

to recapture Louisbourg.

It has always been a player,
if you will,

in terms of what happened here
on the island.

I've been working over on Lot 5,

and this from 1656

to 1804,

that's the same date range
that we're dealing with

of these hidden structures.

Like, that round
circular feature,

and also,
that really deep location,

we were calling it Site 1.

Since their purchase
one year ago of Lot 5--

the four-acre property

located on the western side
of the island--

the team has made a number
of stunning discoveries,

including three
ancient Roman coins

as well as a 14th-century
lead barter token

which is a compositional match
to the lead cross

that was unearthed
at Smith's Cove back in 2017.

However, they have also
investigated the remains

of two mysterious
stone-lined structures.

And within both of them,
they have found

numerous artifacts that have
dated back to the mid-1700s.

You can't get
enough data.
Right.

So, two things come of it. One,

continue to explore Lot 5,

and the second thing is,
you have to chase this tunnel.

-Yeah.
-Yeah.

Way to go, guys.

Okey doke.
We will keep you apprised.

All right.

All right, see you.

See you, guys.

Here comes
the core, guys.
Yeah.

68.

-68.
-68.

61 to 68.

-Yeah.
-Thanks a lot.

After their compelling meeting

in the war room,

Alex Lagina
and Charles Barkhouse

have returned to the Money Pit
area to monitor

the core-drilling operation

in borehole D5N24.5.

A borehole that they hope
will once again reach a tunnel

that may lead directly below
the Garden Shaft

and to the fabled
Oak Island treasure.

Wow. This stuff is really soft.

-Yeah.
-This is abnormally,
unusually soft.

D5n24.5...

could be very close
to the structure.

Given the softness
of this material.

That's very uncharacteristic.

-Yeah, that's very soft.
-Wow, is that ever soft?

Look at that.

When we go into an area

with softer soils,
saturated soils,

usually, the only time that
happens here in the Money Pit

is if we're drilling
near an old shaft

or a collapsed tunnel
or, really,

any other area where
somebody has done something.

And certainly indicated

that there are shafts
in this area, right?

So, again, I think we're
close to something, but...

at 78 feet, we're still about

-25 feet above
our target horizon.
Yeah.

Yep.

Okay. Well, we will see

-what we can find out
with this hole.
-Yeah.

As the drilling operation
continues

in the Money Pit area...

This is our chance
to shine, Rick.

-Lot 5.
-Yep.

...Rick Lagina

and metal detection expert
Gary Drayton

arrive on Lot 5
to look for more clues

that might reveal who built
the mysterious stone structures

located in this area and why.

I've gone over
all this stuff...
-Mm-hmm.

...and I've got a lot of flags.

I've got a dozen flags
in this area.

And all of these spoils came
from the bottom of that hole,

so it should be
the deepest finds.

They are starting their search
in the spoils

that have recently been removed
from a circular depression.

A feature where
they have found artifacts

dating between the 17th
and mid-18th centuries.

-Pretty good.
-Yeah, pretty good.

I'm in agreement, mate.
Pretty good.

After detecting and flagging

a number of potential
targets earlier today,

Gary and Rick
have now received permission

from archaeologist Laird Niven
to dig them up.

-It's out.

Come on.
Let's be something good.

Yeah. That right there? Oh.

It's in my hand,
which means it's small.

It's that.

-A lead shot.
-Mm-hmm.

Small caliber, too.

Yeah. It's an oldie.

Very cool.
-We'll get the lead tested.

I'd say it's period for the lot.

All the finds we're finding
are going way back

to the early 1700s.

Could be anywhere in the 1700s.

Or even a little bit older.

It could be military.

A lead shot?

Found in the spoils removed

from the circular feature
on Lot 5?

And possibly dating back
to the 1700s?

If so, could it be another
clue potentially related

to the Duc d'Anville's
ship's log,

which detailed
a French naval mission

to hide treasure on an island
in this area back in 1746?

All right.

-Let's find some more.
Okay.

That could go either way.

-There, now it's broken up.

-Sounding good.

-That was it.
-A shell casing.

Is it? No, it is not
a shell casing, mate.

That is an unusual find.

-Yeah, what is that?
-Look at that, mate.

I don't know.

-You know, the archaeologists
are over there.
-Mm-hmm.

-Should we call Helen over?
Sure.

Helen. Check this out.

Hey, Gary.
You guys have found something?

Yeah, look at this.
What do you make of that?

Oh. Look at that.

Hopefully,
you have an idea...
-Oh, my God.

-...of what it is.
What is that?

I would say it's, like,
you know, gun-related.

-Yeah?
-It almost looks like a sight.

But it's really,
really special-looking,

and I'm glad you went to "gun,"

-because I was
thinking old guns.
-Yeah.

Yeah.

I mean, to me, that looks like
a gun sight, right?

-Could be.
Yeah, that's nice.

For sure.
-Yeah.

Well, thanks for your input,
Helen.

Yep.
-Okay.

We have found items

that we believe
have some military context.

This may be another of them.

Again, this speaks
to an enterprise here

could possibly
have been conducted

by the Duc d'Anville expedition.

The good news is,
they can be tested.

How about taking this lot
back to the lab?

I'm really, really curious.

That copper barrel-shaped
artifact, that's special.

Let's add that to the database
and keep going.

Okay, mate. Back to the lab.

The following morning,

while the drilling operation
continues

in the Money Pit area...

Looks like
we'll get 'er down that.

Another foot and a half.

Gentlemen.

We've assembled because we are
reaching a critical juncture.

The very centerpiece
of this year's work

is deepening the Garden Shaft.

...Rick, Marty
and other members of the team

gather in the war room
for a meeting

via video conference
with representatives

from Dumas Contracting Limited.

Okay, well, you've got us all,

uh, on the edge of our seats.

We'd like to know
the latest developments,

and when you're gonna be
out here making shaft.

Yeah, very good.

As everyone's aware,
uh, in order to facilitate

the work planned
for Oak Island this year,

we need to have a code
of practice in place

that's authorized
by the Department of Labor

in the province of Nova Scotia.

While the team continues
their core-drilling effort

to track the tunnel
that is believed

to run ten feet below
the Garden Shaft,

they are eager to know just
when Dumas will be authorized

to deepen the structure
by some 20 feet

so they can personally find out
just where the tunnel leads

and what it may contain.

Most recently,
we've been updated

by the Department of Labor,

where they have
suggested segmenting

the scopes of work this year

into one code of practice
that would govern

the deepening
of the existing Garden Shaft,

and then a second code
of practice

that would enable us
to go laterally

and perform our tunneling work.

-Yeah.
The plan
would be to split up

the-the code of practice,

and we're definitely shooting
for a-as soon as possible to get

everything, uh,
submitted to them,

uh, with respect
to the shaft deepening.

Okay.

Dumas needs permission
from the various authorities

here in Nova Scotia,
mainly involving safety.

They have to get approval
on the code of practice,

which basically sets out
all the conditions

upon which they will be allowed
to deepen the Garden Shaft

and possibly tunnel out from it.

What is your expectation

regarding issuance
of the code of practice?

This code of practice,
we anticipate it being issued

certainly before
the end of the month,

related to, uh,
the shaft deepening.

Otherwise,
our crews are prepared,

and we are operationally ready
to come out

and operate on the island
this summer.

Okay. That's all my questions.

-Anybody else?
No, I'd just...

-keep your fingers crossed.
-Yeah.

We have to respect

and honor the requests
of the government authorities,

but if the code of practice
is delayed much further,

I think it's certainly
is going to affect

all aspects of our work
in the Money Pit.

Well, we look forward to
getting you guys back out here.

-Yeah.
-This, uh, some exciting times,
and, you know,

we welcome your participation
and efforts.

Thank you very much
to the entire team.

We're gonna do this safely.

-Sounds good.
-Okay.

-Thank you.
-You got it. Bye.

We'll be in touch.
Thank you.

Looks like
we'll get 'er down that.

As members of the Oak Island
team continue

drilling in search
of a possible treasure tunnel

in the Money Pit area...

Hello, everybody.

-Wow.
Look who's here.

...on Lot 5, Jack Begley

joins Helen Sheldon,
Jamie Kouba,

Lindy Martin and Fiona Steele

as they investigate
a mysterious rock foundation

that was first discovered
one year ago.

Last year,
when we found that deep wall,

I've been wondering
what this place is.

-Yeah.
Curiously,

when this feature
was found in 2022

by Rick and Gary Drayton

while they were
metal-detecting in the area,

the team uncovered
numerous artifacts

such as pottery and pipe stems
that are believed

to date back
to approximately 1750.

The same time period
as the Garden Shaft

and mysterious tunnel that they
are currently investigating

in the Money Pit.

So, the plan is to get the
entire surface of it uncovered.

-Mm-hmm.
It was also believed

by the archaeology team

that this feature
was deliberately buried.

Any idea yet
on what this might be?

It's early days yet.
-Maybe it is some sort

of a homestead,
but why would they bury it

-under so much soil?
-There was a lot of soil

-on top of it, I agree with you.
-Yeah.

Like, this isn't typical
for any settler to do, right?

To just bury their homestead?

No, normally,
it would be naturally buried.

With the passage of time,
it would've filled in.

See, I kind of feel like
someone was--

might have been trying
to hide something.

And why? We're so far away
from the Money Pit.

People did used to bury
their things as well.

-Mm-hmm.
-Right? You know,
their stash of precious items.

Yeah. Hopefully, there's
a bunch of items in here

or maybe it leads deeper.

There might be clues once
we get to the bottom of this.

And if this is as early as
we think, like, even say 1750,

this predates the discovery
of the Money Pit.

So, it may tie in
to more than that. Who knows?

Maybe it's an encampment.

-Yeah, it's possible.
-And they buried them

to hide evidence
of them being on this lot.

But there's so many coins.

And from what we found,

it could be connected directly
to the Money Pit.

We've only just started
digging up this feature,

so, hopefully, the finds

just continue to explain
exactly when it was first dug

and what it might have
been used for.

As members of the archaeological
team carefully excavate soil

from within
the mysterious foundation,

Fiona Steele sifts through
spoils with a fine screen

to look for clues
and potential valuables.

Helen, I actually found a shard,

uh, which I'm surprised at,
in that top layer.

-Did you really?
-Yeah, it's not very big, but...

It was just in that top layer.

-Just a little one, but...
-Yeah.

...nonetheless, it is a shard.

Yeah.

Uh, possibly creamware.

Because it has that slightly
yellowish tinge to the glaze.

A possible piece
of creamware pottery?

Because this type
of clay earthenware

could date back to the mid-1700s

and predate the discovery
of the Money Pit

by nearly half a century,

could it be another
critical piece of evidence

to help identify

who may have constructed
this feature?

-So, we'll definitely...
-Slightly out of place.

-...keep this separate, then.
-We'll keep it separate.

Yeah, yeah. Okay.

Great find.

I just wasn't expecting that.

Yeah.

It's exciting.

Later that afternoon,

in the Interpretive Centre...

So, what do we have today?

This artifact came off of Lot 5,

not too far off
the round feature.

It may be gun-related.

...Rick Lagina, Craig Tester

and other members of the team

meet with archaeologist
Laird Niven

and archaeometallurgist
Emma Culligan

to get their analysis
of the artifact

found one day ago on Lot 5.

So, it's a ramrod guide
for a musket.

This would be in there,

and the ramrod would
come through the front tube.

This would be the center tube,

and it would be held in
with the third one.

The smoothbore long gun,
known as a musket,

was invented in Europe near the
beginning of the 16th century.

A feature known
as a ramrod guide

was designed
for aiding the operator

in the loading of lead
or stone projectiles

into the muzzle of the musket.

And what type of musket, mate?

-That's the million-dollar
question.
-Exactly.

If it's a musket, that would
make it pretty old, then.

Yeah.

Anywhere from 1600s

-to 1800s.
Yeah.

But you got to love
that patina, mate.

-Yeah. Yeah.
-That tells you it's really old.

The only strange thing is that

-there's a little
tiny hole here...
-Yeah.

...which I haven't seen
in-in others.

Well, it seems fancy.

But it'd be nice to know...

French, British?

Mm-hmm.
Yeah.

You know,
some nationality to that.

Do you want to see the CT image?

Sure.

Earlier this morning,
Emma processed the artifact

using the SkyScan 1273
CT scanner.

By emitting nondestructive
X-ray radiation,

the device can penetrate
built-up corrosion on objects,

revealing clear 3D images
of them,

along with their finer details.

So, it's just loading.

The little hole
just turned big.
Yeah.

That's a clean scan.

Yeah.
-Yeah.

But you see on the top right?

Yeah.
Oh, yeah.

It looks like
there's Roman numerals.

Yeah. Didn't we get
those crazy Roman numerals

-on the U-shaped structure?
-Yeah.

Yeah.

That is really cool.

It looks like
there's Roman numerals.

That is really cool.

It looks like "VIIII."

In the Interpretive
Centre, Rick Lagina,

Craig Tester
and members of the team

have just discovered
that the potentially ancient

musket artifact,
found one day ago on Lot 5,

curiously bears Roman numerals.

The only thing I can think of
is that could be a...

...it could be a regiment,
I guess.

-It's an odd thing to mark.
Yeah.

Yeah. Looks like a "VIIII,"
doesn't it?

Yeah, and we saw that
in Smith's Cove.

-Right.
-On the U-shaped structure.

-Yeah.
-Yeah.

In the early 1970s,

Rick, Marty and Craig's
late partner Dan Blankenship

built an earthen cofferdam
that surrounded Smith's Cove

on the eastern end of Oak Island
in order to drain the area

and look for evidence of the
legendary flood tunnel system

that acted as a booby trap
for the original Money Pit.

Dan was amazed
to uncover a 65-foot-long

U-shaped wooden structure
that featured Roman numerals

and which he believed
was constructed

as a surrounding barrier
for the flood system.

There's probably a ramrod

waiting for us
somewhere in that area.

Is it possible
that the U-shaped structure,

along with the other features
and artifacts

that have been found on Lot 5

may be connected
to a 1746 ship's log

which detailed how treasure
was "securely buried"

in a deep pit
on a wooded island?

Finding the Roman numerals

carved on that little bit
of ramrod guide,

it brought back memories
of, certainly,

the U-shaped structure.

We've never found
Roman numerals before

on any other artifact to date.

And to have them found here,

I think the two
are strongly connected.

Absolutely fantastic.

This has given us hope that
there's more finds on Lot 5.

I say we give it another shot.

I want to find the rest of it.

-I'm in.
-I'm with you.
-All right. Good luck.

Thank you, Laird.
See you, Laird. Cheers.

Thanks, Emma. Thanks, Laird.

Following the meeting
in the Interpretive Centre...

We're just at 98 feet
below grade.

...Alex Lagina has joined

other members of the team
in the Money Pit area.

So, the next core

-is our, uh, is our core.
Yep.

If it's there,
we'll see it in our next core.

After nearly two days

of slowly drilling through
previously disturbed soil,

the team is about to reach
the target depth of 105 feet

in borehole D5N24.5,

where they hope to once again
encounter the tunnel

that is believed to run
directly below the Garden Shaft.

This looks interesting.

Well, we have a core coming.

The core is up.

Oh, my.
-Yeah.

I think we hit wood.
-Wow. It looks like

a chunk of something
coming right out the base.

Looks like we got wood
right off the get-go here, guys.

You know, oftentimes,
when we find wood in cores,

there's not much there.

-Oh, yeah.
Wow.

That is excellent.
That's really interesting.

However,

this time, we pull up a timber.

It's a vertical timber.
This is really odd.

It looks like we've got
a section of beam.

Oh, yeah. Look at it.
-Vertical support.

Oh, that-- yeah, that was the
top-- that's up towards the top.

-Thank you, Colten.
-What is that, Colten?

108?
Uh, 108.

-108? This is the bottom.
-Thank you.

Oh, wow. That's a lot of wood.

That's a lot of wood, for sure.
My gosh, guys.

What do you think it is, Terry?

I think it's just uprights
of a tunnel.

The main point of this borehole
is we're looking for that tunnel

that goes under
the Garden Shaft.

Hitting wood helps confirm

that that is our tunnel.

Little bit more.

And the very top.

Oh, my.

That's a pretty significant
chunk of upright.

-That's a big tunnel.
-That's a big tunnel, for sure.

Six.

Seven.

So, I got seven and a half foot
of tunnel.

I would agree with that.
Seven and a half
feet of tunnel?

-Seven and a half foot.
-Oh, that's a lot longer
than I thought it was.

-Yeah.
-Yeah.

This core is almost 100% wood,

which is really great, and it
means that we hit the tunnel.

If that's true,
then this tunnel,

and anything it's connected to,
becomes our next best target.

Maybe the tunnel
leads to the Money Pit.

Let's get Rick up here.

Absolutely.
I'll call him.

Sounds good.

Uncle Rick.

Hey.

So, I'm up with the guys
at the drill table.

Uh, we just hit
our target depth.

We were looking to hit a tunnel,
and what we did hit

was approximately seven
and a half feet of upright.

Yeah. But it does really,

really well define
the height of the tunnel.

if it's a tunnel.

Sounds good.
We'll see you soon.
See you, Rick.

We've got wood right there.

And it stops cleanly
right there.

That's the cut top right there.

I knew if I stayed away long
enough, you'd find something.

-Yeah. Exactly.
-Hi, Rick. How you doing?

-Hey.
-There it is.

After being informed
by his nephew Alex

that the team has just drilled

into a seven-and-a-half-foot
tunnel more than 100 feet deep

in borehole D5N24.5...

It's quite remarkable.
Yep.

...Rick Lagina has
arrived in the Money Pit area

to assess the potential
breakthrough discovery.

There's the bottom right there

at 108 feet below grade.

I think we hit a whole section
of a support beam.

That looks like it's hand-cut.

I see, yeah.

I see hand-shaping there,
for sure.

That's a good sign.
-Yep.

-Yeah.
Yeah, that's
a really good sign.

-Right here.
-Absolutely.

You can see
an adze cutting in there.

In here? Yeah, it's...

Yeah, you can see
right there, too. Look, see?
Beveled edge here. Yep.

This is cut here.

Oh, yeah.

The adze cut
is really quite interesting.

Hand-shapen
rather than milled.
-Yeah.

Believed to have
first been invented

more than 2,200 years ago
in ancient Egypt,

an adze is a type
of construction tool

featuring a sharp blade

that runs perpendicular
to its handle.

They were widely used
to shape wood

for structures
and sailing vessels

until being phased out
during the 18th century

by mechanized saws.

Somewhere, there is a shaft...

-Somewhere there is a shaft.
-...from which this tunnel
was dug.

And a big shaft,
because you think, if you're,

if you're bringing down seven,

-eight-foot-tall pieces
of lumber...
-Yeah.

-...you don't have a tiny little
shaft you're going down into.
-That's it.

Right.

If the team has truly found
a large tunnel

that was constructed
with adze-cut timbers,

could it mean they have
once again encountered

the same tunnel that has been
dated to as early as 1735?

Or might it be
an even older structure?

For me, you don't build
a tunnel like this--

-I mean, it's a seven
or eight-foot tunnel...
-Yep.

...unless you are
moving material.

-Yeah.
-Or you're moving

something important.

My opinion would be, unless
you were depositing something,

I don't see why you would
build a seven-foot tunnel.

'Cause you could very easily
walk down this.

Yeah.

Given the 228-year history,

no searcher
did this kind of work.

The only other thing I've seen
that's that scale

-is when we were in Italy
last year.
-Yeah.

Which, at the time, I thought
were absolutely enormous.

One year ago,
Rick and Alex Lagina,

along with other members
of the team,

traveled nearly 3,700 miles
to Italy

in order to investigate
possible ties

between the Knights Templar
and the Oak Island mystery.

Boy.
Stunning.

Everything is just
so well built.
-Yeah.

While there, they visited
two man-made cave systems

that were used
by the Templar order between

the 12th and 14th centuries.

We have seen this symbol before.

H+O Stone.
Yeah.

One of the massive
labyrinths located

in the town of Osimo

contained a carved symbol
that was also found

on Oak Island in the 1920s.

Now, that's a direct tie
to Oak Island.

This arm should be

a bit longer than this one.

And another cave system
that they visited

in the nearby town of Camerano

featured an entire section
that, incredibly,

was an exact match in design
to the 14th-century lead cross

that was found
on Oak Island in 2017.

3,000 years later,
it still stands.

This, I think, is a twist,

-and that's the worked
inside edge.
-Yep.

When all of the other
searcher tunnels

that we've discovered have been

four or five feet tall,

certainly nothing taller
than that,

why seven feet tall?

And the enormity of the labor
associated with that.

Will it prove
to be something dramatic?

Let's get some cameras
in there, and then,

develop a strategy
by which you can

possibly physically access it.

So, here's what I think.

I think we should get Paul
up here with the camera...

-Absolutely.
-...because we want
to take a look.

The drillers, at this point,
are very important.

They did the work, right?

And they might be able to
tell us how they would proceed.

And, uh,
Paul can start putting--

Well, there they are
right there.

Hello. How are you doing, guys?

Well, you tell us.
That's-that's what

I was just telling everybody.

You guys did the work.

So, we want to be able
to take a look,

if possible,
down in that cavity,

if it is a cavity.

-How do we proceed from here?
Probably best

to pull back that casing
to expose

a relatively open hole.

And that probably would be
your best chance of getting

-an open hole
to physically see something.
Right.

That's a good piece of wood
that you pulled out of there,

-so there's a bit
of a void there.
-Well, it's...

it's hand-cut,
which is quite interesting.

Oh, yeah?
Oh, really?

Yeah.

Yeah, that's nice, eh?

So, we should have an open
section of tunnel to look at.

Okay. We're in your hands.

All right.
Let's go for it.
Sounds good.

-All righty. Thank you, guys.
-Thank you.

This is exciting.

We have, uh, 30, 40 feet
before we get to that area.

Then we'll have to zero it out
when you're right at the top

of the casing and put it down.

In the Money Pit area...

-Hey.
-Hey, guys. How are you?
You guys ready?

...after drilling into
a seven-and-a-half-foot high,

potentially ancient
wooden tunnel

more than 100 feet below ground

in borehole D5N24.5...

-I'll start dropping this down.
-Yep.

...Rick Lagina
and members of the team

are about to lower a camera
down into it,

in the hopes of seeing
what it might contain.

Alex,
can you pull me tight?
-Yep.

Okay. Now I'm gonna take
a little bit more slack.

Here we go. I'm gonna
put it in and we'll zero it.

The lights are on.
There you go.

-All right, do we still
have a clean image?
We do.

-Yes.
Here we go.

Okay, so we're going
down the casing.

Clearly see the edge of it here.

In order to investigate
the mysterious structure--

or tunnel--
the team is utilizing

the Inuktun Spectrum 120
high-definition camera.

The device features a lens
that can pan 360 degrees,

and is designed to operate
in low-light conditions.

What are you at now?

Five meters.
-Okay.

The last time we drilled
into this tunnel

on the east side
of the Garden Shaft,

there seemed to be
an opening, a cavity.

We couldn't use a camera
at the time,

but we're hoping,
with this borehole today

that-that we'll get
one more shot at it.

The number one thing
is to get a camera down there

and see what we've hit,

and hopefully, after that,
we can get a clear image.

I don't-- I don't...
Whoa!

Whoa.
-Okay. In water.

Yeah. We just went pitch-black.

We can't even see the casing.

So, that's seven
and a half meters.

Right there.
Yeah.

Pull it, pull it back up
out of the water.

Let's watch
the transition going in.

Yeah.
-Look at the dirt on the lens.

Go in. Back down in.

Slowly.

There.

As soon as we go into the water,
we're black.

The second it drops under
an inch, the light's gone.

-Like, pitch-black.
-Yeah.

Well, that pretty much
writes the tale right there.

Yeah.
-Oh, I can see the water.

It's murky. Really murky.

I-I don't know that we need
to go any further here.

No.
Yeah.

I am really struggling a bit

for one simple reason:

the peculiarity
of the construct,

i.e., being seven feet tall,

it presents all kinds of
"What's here?"

-It's all stirred up, for sure.
Very fresh.

It's-it's very recently
disturbed.

Where's the beginning?
Where's the end?

Who was down here?

There was a tremendous
amount of material

to be removed from that.

Why go to those efforts?
And that's a key question.

Why do you need seven feet?

What's in there?

Let's get the drill out the hole

-so we can keep it moving.
-Yep.

I agree.

We hit wood, we hit a void.

It almost certainly is a tunnel.
It's at the right depth.

It appears to be that the tunnel
from the Baby Blob area

passes directly under the
Garden Shaft and continues east.

A lot of data
points to the likelihood

that there is something there,

and I'm speaking about
the metals in the water.

This tunnel
we're trying to follow

and this chamber we've found

might be the source
of the high metals.

If there's a tunnel,
we'll follow it.

So, all in all,

I think we're closer
than we've ever been.

So, how far
are you gonna go over

for the next hole
after this one?

We can pull ahead and drill

-around the 27 line...
Yeah, okay.

...and look for connectivity
between the two tunnels.

Okay. Sounds like a plan.

All right.
See you, Steve.

We'll see you later.

For more than two centuries,

generations of searchers
have made discoveries

on Oak Island suggesting
that they were on the verge

of solving the mystery,

only to have their dreams dashed
by unforeseen events.

Rick, Marty and their team have
also once again experienced

the firm grip that the island
has long kept on her secrets.

And while
all of their predecessors

eventually had to give up
or move on,

one thing is certain.

The Laginas have no intention
of stopping

until they hold the ultimate
answers in their hands.

Next time on
The Curse of Oak Island...

Here it comes.
The Garden Shaft project

is finally underway.

This way a bit.

Time to open Pandora's box.

Oh, boy.

-Wow.
-Wow.

I'll tell you, Jack,

it's the first time
in 40 years of fieldwork

I have seen
something like this buried.

They're hiding something.

Ooh. Interesting.

Brilliant.
