Tonight on
The Curse of Oak Island...

It's catching on something.

Look at that thing.

There's something curious

- about this boulder.
- That's like

the Nolan's Cross boulder.

This soil is super compact.

This was constructed
for a purpose.

- Whoa.
- It's an almost exact match

to a Money Pit sample.

Wow.

The association
that could be made

is mind-blowing.

- What is that?
- Pretty solid chunk of metal.

That could be a
piece of the treasure vault.

Yep.

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, Paul.

Morning, guys. How's it going?

Well, we're hoping
for an update.

So, we finished
drilling a couple holes.

- Good man.
- As a new day

begins on Oak Island

for brothers Rick
and Marty Lagina,

they arrive in the
fabled Money Pit area

to check on the
progress of an operation

that they hope will
finally reveal the answers

to a 229-year-old
treasure mystery.

It's getting close.

The first hole,
kind of seemed like

it was deflecting off a wall.

Where are we again?

So, that... it would
be the north side.

One week ago,

after extending the
mid-18th century structure

known as the Garden Shaft
down to a depth of 90 feet,

representatives from
Dumas Contracting Limited

used a coring drill to
penetrate a mysterious tunnel

located at a depth of 95 feet,

which is believed
to run due west

toward an area known
as the Baby Blob.

It is in this region
where water testing

that was conducted in
previously drilled boreholes

has detected high-trace evidence
of silver, gold and other metals

between 80 and
120 feet underground.

There is a structure of
some sort down there,

a wooden structure of
some sort, and you're about

- to unearth that, right?
- That's right.

Okay. That's enough said for me.

So, today, we
put in the landing.

We're adding another set.

Now, after
unsuccessfully drilling

into the believed
tunnel for a second time,

over the course
of the next week,

Dumas will proceed
with constructing

the final level, or set, to
extend the Garden Shaft

down to a total
depth of some 95 feet,

where they hope to intersect
the mysterious passageway

and find out what
it may contain.

We've invested a
lot of time and energy

delineating this tunnel.

And I think there's
great anticipation

on everyone's part

to try to, well, to not
only put eyes on it

but to see where it may lead.

If the tunnel
predates the shaft,

it makes the tunnel
far more interesting

than just finding a
"previously unknown" tunnel.

- It's all good news.
- Yes.

I'm starting to get eager now.

- You've got my toes tickling.
- You're so close,

- you can smell it there now.
- Yeah, yeah.

All right, let's let
him get back to work,

because we're
poised to finally do this.

Okey doke.

- Let's go, guys.
- Yep.

- Thanks, Paul.
- Okay, thank you.

Thank you, Paul.

As the operation

to deepen the Garden
Shaft continues...

- Here we are.
- Yep.

- We're back at it now.
- Yep.

- H-8.
- H-8.

Approximately 60 feet

to the southwest,

geologist Terry Matheson

and Oak Island historian
Charles Barkhouse

are monitoring a new
core drilling operation

in Borehole H-8,

a borehole that was
previously excavated in 2017.

This turned into a very,
very interesting hole.

- For a number of reasons.
- My goodness.

What is this?

After
initially recovering pieces

of parchment and
leather book binding

with a six-inch-diameter
core barrel in H-8,

Rick, Marty and their
partner Craig Tester

speculated that they
may have encountered

the fabled Chappell Vault,

a seven-foot-tall treasure
chest encased in concrete

that Frederick Blair
and William Chappell

reportedly drilled
into back in 1897

and recovered not
only evidence of gold

but also, a piece of parchment
bearing the letters "V-I."

Come on, baby.

Make hole!

Incredibly, when
the team expanded H-8 by installing

a 60-inch caisson
in the fall of 2017,

a large object was encountered
at a depth of 170 feet.

He's on something.

He thinks it's perfectly flat.

Wood?

He thinks wood.

Unfortunately,

as the team drove the
H-8 caisson deeper,

in the hopes of
breaching the vault,

the plug, or earthen
spoils inside of it, fell out,

pushing the potential
treasure chest

somewhere deeper below ground.

Anyway, today, we're
going back down this hole

all these years later.

We did not finish that dig.

So, it's possible that
it broke the vault open.

So, this is gonna be a look

at the sediments,
or pieces of the plug.

Maybe pieces of
treasure, Charles.

Yeah.

Now, after recent water tests

and subsurface
scans in this area

have offered more evidence
of potential valuables,

it is Rick, Marty
and the team's hope

that if they can pinpoint
the possible location

of the vault, they will
arrange to excavate

a much larger diameter
caisson in order to recover it.

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

had to have migrated somewhere.

The possibility certainly
exists that this is an area

to which the Chappell
Vault has fallen.

It could be deeper, and
we'll certainly press on.

So anyway, whatever...
We-we're in it to win it.

We got to exhaust
all possibilities.

Cross your fingers that
we hit the right section,

and maybe the best section.

And hopefully
today we'll find out where it went.

Exactly.

While the excavations proceed

in the Money Pit area,

in the southeast corner of
the triangle-shaped swamp

located near the
center of Oak Island...

- This is a great day.
- Yeah.

That is impressive.

- That should go the distance.
- Yeah.

Metal
detection expert Gary Drayton,

Jack Begley and Billy Gerhardt

are about to conduct
a new large-scale dig

in a region of the brackish bog

near the potentially
500-year-old stone road.

So, we're gonna be digging

in the deepest part

- of the swamp.
- Yeah.

We haven't really
done a whole lot of work

in this particular area,
and it's surrounded

by really great finds, so...

Yeah. With the stone road

and stone path,
this was a work area,

so we got to keep our
eyes peeled for anything.

- Right.
- Excellent.

Well, should we get stuck in?

Yep.

Of the many
remarkable discoveries

that the team has made over
the past decade in the swamp,

the stone road, or
possible ship's wharf,

may be a critical key to
solving the Oak Island mystery.

Look at how
beautifully constructed.

It is not
only a near identical match

to a road that Rick Lagina
and members of the team

saw in 2021 in Alqueidão
da Serra, Portugal,

where the Portuguese
sect of the Knights Templar

maintained a stronghold

from the 12th to
the 17th centuries...

This looks old.

- That does, yeah.
- Yeah.

But it is
also in an area of the swamp

where they have
unearthed numerous clues

such as a heavy
chain with a hook,

suggesting the road was
created in order to off-load

some kind of cargo
onto Oak Island.

All right, first bucket
of opportunity is coming up.

Now, it is the team's hope

to find more clues
that will help explain

the true origin
of the stone road,

and hopefully,
evidence of valuables.

Gosh.

Smells like treasure.

The southeast corner of the bog

is the most interesting
location for one simple reason.

We want to understand the reason

for the construct
of the stone road.

- Hey.
- Hey, Rick.

And if it had something to do

with the original
treasure story,

then that whole area
is of significant interest.

Stinky.

You guys get back to
work, I'm gonna poke about

in the pile, try to...
see what I can find.

- Okay, mate.
- Okay?

Come on. Where are you?

Nothing.

Look, I've said this many times.

I hate that swamp
'cause it stinks.

But every time we've dug in it,

we've recovered
interesting stuff, clues,

and I don't think we've
dug ten percent of it,

so we're not done.

No targets yet?

Not yet, no.

Wow, he's catching on something.

What is that?

Look at that.

Rious a,

unlike other ones in the swamp.

It's like it's sitting on
top of the peat, right?

Which it shouldn't be if
it's, if it's glacier, right?

So it was moved before.

Yeah. I-I agree.

Near the stone road

in the southeast
corner of the swamp,

Rick Lagina and other
members of the team

have just uncovered
a massive boulder

that may have been
purposely placed into position

by someone, but if so, by whom?

And for what purpose?

Can't believe
how easy I can move it.

The other thing that's
interesting here is,

see how it's, it's
a row of rocks?

Yep.

We got this big
flat rock and it's like a...

giant set of stone stairs
almost here coming up the bank.

- Hard to say.
- Yeah.

Maybe they were doing
work around that boulder.

Yep. We
know the road is there,

we know the path is there,

we know the Money
Pit is right there.

The opportunities are limitless

as what could have went
on right in this very spot.

Absolutely. Yep.

Let's just GPS it
and keep digging.

A row or staircase of stones?

Leading to the massive boulder

in the southeast
corner of the swamp?

Could this feature
have been constructed

as some kind of
symbol? Or marker?

And could it be
related to the stone road

and perhaps created

in order to hide
something of great value?

I'm not going any deeper.

It's as though

there's some sort
of rock platform here.

So it's not well-seated
in the organics

and the inference is
that it was placed there

and not deposited by a glacier.

That makes it interesting.

Look at that.

And so my first
thought really is

we need to find a
way to take a look at it.

That's a board.

How deep do you think it was?

- Two feet.
- Yeah.

Two feet. It's out there though.

This is definitely
a shaped board.

That is thick.

Hey, check this out, Rick.

Look at the thickness of this.

Now this is in good condition,
so it's got to be a good wood.

That looks like it could be
ship's decking or planking

'cause of the thickness of it.

That's a big one.

But there was no
metal ringing off of it?

No. I checked it for
fasteners. No fasteners.

It was two feet down
and it was out there.

The planks they are finding

could be called ship's planking.

We've found boards that we think
might be associated with a ship.

That very near
vicinity, of course,

one of the most enigmatic
finds we've ever made

is the ship's railing
from 600 or 700 AD.

So that area, hopefully,
will yield some answers.

It's worth bringing back,
washing it off, take a look,

see if there is anything
on it, nail holes or anything.

All right, mate.

We're finding
more questions in the swamp.

Every time we've
undertaken draining it

and digging somewhere,
we've found something.

And some meaningful somethings.

But no one knows why
these things are in the swamp.

It's swampy.

So, yeah, would
I like an answer to that?

Yes, I'd like an answer to that.

Simple answer would be,

I'm hoping for
whatever is, is there.

Any metal is gonna
stand out in this stuff.

That would be something.

All right. Let's see
what we can get done.

Later that afternoon,

as the excavation and
the drilling operations

continue in the Money Pit area,

near the shoreline on Lot 5,

located on the western
side of the island...

Wow, you guys have
done a lot of work

since I've last been here.

I bet it looks
different, doesn't it?

A lot different.

Jack Begley joins members

of the archaeology team

as they continue their
meticulous excavation

of a mysterious
stone foundation...

A foundation that was
discovered earlier this year

buried beneath a
circular depression.

So, what's going on over here?

When we first expanded westward,

we thought that this stone
line feature was gonna continue.

- Yeah.
- And we assumed that this was where

the house structure sat
and that was just a basement.

But it is starting to curve in,

which is bizarre.

- It doesn't make any sense.
- Yeah.

But it's too big to be a house.

It's an occupational
spot for sure.

In the past year,

the team has made
significant discoveries

in and near this
feature that suggest

it may have been
occupied by multiple groups

during different time periods.

These discoveries include

a 14th century
lead barter token,

which is a compositional
match to the lead cross

that was discovered
at Smith's Cove in 2017,

two Venetian glass
beads, which were not only

once considered a
form of valuable currency

but which could date to
between 1500 and 1650,

and several metal tools,

which have been
scientifically linked

to the birthplace of
Sir William Phips...

The English politician and
privateer who some believe

buried a large cache
of Spanish treasure

in the Money Pit back in 1687.

So the plan today
is to make sure

that we define this
edge really well.

Well, we've been finding some
really good stuff around here.

I can't wait to see what
else we dig up in here.

All right. Well,
let's get to work

and see if we can figure
out what's going on here.

While the
archaeologists remove spoils... or earth...

From the foundation,

Jack is sifting them
through a screen

for clues that might
explain how this feature

may be connected to
the Oak Island mystery.

Based upon the different dates,

I'd say this starts to
speak more and more to...

people being on Lot 5 earlier.

Bits of brick and
pottery and glass.

That's pretty cool.

Hopefully, we
continue to have more finds

and figure out who
exactly was here

and is it related to
the Money Pit story.

- Thank you.
- You girls are digging quickly.

Let us know if
we are swamping you

- and we'll give you a hand.
- No, no, no.

You're fine. I'm keeping up.

Good God.

Okay.

This is kind of
getting interesting.

This soil over here
is super compact.

It's not like the stuff
that was over there.

I may have found mortar.

Whoa.

- This is strange.
- Like concrete.

It's really strange.

- Hey, guys.
- Hey.

- We have another surprise.
- Cool.

I can't wait to hear
your take on this.

Near the shoreline of Lot 5

located on the western
side of Oak Island,

archaeologist
Laird Niven arrives

at the mysterious
stone foundation

after being informed

of a potentially
important discovery.

All of a sudden,
I hit this stuff

that's got a lot of
ash mixed into it,

crushed-up shale and stuff.

You can hear it.

It's, like, a-a grayish color

and it reminds me of, like,
a crude mortar or cement.

The mortar looks an awful lot

like the mortar that I found
when I was washing through

- Money Pit material.
- Really?

Over the past several years,

the Oak Island
team has discovered

different forms of concrete

in several of the
massive caissons

they have excavated
across the Money Pit area.

A prime example was in 2019,

when this type of substance was
recovered in the spoils of RF-1.

A ten-foot-diameter caisson

located just a few
feet northeast of H-8,

which was also excavated
in the hopes of locating

the reportedly
concrete-encased Chappell Vault.

We could compare this sample
with the Money Pit sample.

See if they come
from the same source.

I would love to do that.

If you could get me a
sample, I'll take it right back

and, see what Emma has to say.

Okay, yeah, that sounds good.

This is a really difficult
feature to get answers from

because we don't quite
understand the structure.

So we're not exactly
sure what we're looking for.

It's important for us to
take a sample of this soil.

It would be interesting
to see if it corresponds

with the Money Pit.

And if it does, it
would suggest that

those areas were
operating at the same time

and were related.

Excellent. You are
doing a great job.

I like this. I like
what's coming up.

I don't know what
it is, but I like it.

We're trying
to figure that part out.

Okay. I'll take this
back to the lab...

Perfect.

And check in on you later.

All right.

I need to get back to sifting.

The following morning...

- Ready?
- Yep.

While representatives
from Dumas Contracting Limited

continue their efforts to
deepen the Garden Shaft

in the Money Pit area...

Are we getting our core?

- Here it comes, right now.
- Right now.

Several feet to the southwest...

God, I hope
something good is in this.

Marty Lagina and his son Alex

join other members of
the team at Borehole H-8

where they hope to find
evidence of the Chappell Vault

somewhere below
a depth of 180 feet.

It's a long one.

Get ready to slice and dice.

We know we had
the canister H-8 go down,

and it hit something big

that moved around underground
and went somewhere.

We're sure of that.

Yeah, there's a
lot of water in there.

It is possible that H-8

is very near the
original Money Pit.

So, we have to look deeper.

How deep are we, Adam?

We're at 211.

- 211?
- It's gonna be a mess.

Let's get our hands
dirty, gentlemen.

Ready?

This is the silt and the clay

and there is a few
little clumps of material

that might have
fallen from above.

There's a little chunk
of wood, right there.

It's just below all
our silt and whatnot.

And this sits just
on top of bedrock.

Start right there, Charles.

Come on. Be something.

You got something.

I've got something right here.

Excellent.

Want me to wash it down?

- Okay, guys.
- What is that?

A pretty solid chunk of metal.

That could be a piece
of the treasure vault.

My goodness. Cool.

This material to here,

that could be part of
the plug. No question.

The plug could
have disintegrated

and fallen off to one side.

- And all that stuff.
- That's right.

The plug that fell out was
nine feet or a little over nine feet.

- Right.
- And they chewed down one side of it

so we could still get
a significant size plug

- on one side or the other of the vault.
- Yep.

If the team
has found a portion of the plug,

or the spoils, that may have
pushed the Chappell Vault

deeper underground
when the H-8 caisson

was originally
excavated in 2017,

could that mean that they
are close to pinpointing

the legendary
chest of valuables?

- Hey, Rick.
- Hey, Rick. -Hi, Rick.

- How are you doing?
- Hey.

How deep are we?

Well, we are at 211 down there.

But here's the
thing, that little bit

could have been our plug.

Because if there
was a plug in there,

it probably didn't stay intact.

It probably broke up.

Well, that and
probably slid the vault

to one side or the other.

Slid to one side
or the other, right.

So, we need to move
the rig and come down

in another location.

I do believe

that material, whatever
was contained within it,

has fallen to a
far greater depth.

To what side and what
cardinal direction, we don't know.

I think at this point

the only way to exploit
this possible clue

is to continue to
do some drilling.

Okay, we need to figure
out where the next hole is.

Okey doke.

Sounds like a plan.

- Yep.
- Thanks, guys.

Later that afternoon...

Hey, Roger.
How are you doing?

Soggy but otherwise good.

Come on in and sit down, guys.

Rick and Alex
Lagina, along with Scott Barlow,

join Roger Fortin in the Dumas
trailer in the Money Pit area,

where they are about to
receive a carbon dating report

regarding a wood sample

that was obtained one week ago

from the possible
treasure tunnel

located below the Garden Shaft.

I'm going to call
Craig and my dad

and get the info
right from Craig, so...

These guys from
Dumas bought into this process.

This is not a job to them.

They're excited, they're
interested, they're invested.

I want to see that somebody's
been down there a long time.

They have a right to know

what the fruits of
the labor has been.

So, I hope the
results are informative.

- Hey, Alex.
- Hey, Craig.

Um, I got Rick,
Scott and Roger here

and my dad's on the other line.

So, we are looking forward
to the carbon dating results.

Wow.

That's exciting.

Wow.

It is a
potentially historic moment

for Rick, Marty, Craig
and the Oak Island team.

That is, yeah,
that is something.

Yep.

A carbon dating test

that was conducted
on a wood sample

collected one week ago

from the possible treasure
tunnel below the Garden Shaft

has indicated that the
seven-foot-tall structure

could be nearly 400 years old.

So, there's a chance

this is connected to
the original Money Pit.

Right.

Incredibly, this
is the second wood sample

taken from the
mysterious tunnel this year

that has been dated to
as early as the 1600s.

This means that it
was likely constructed

more than a century
before the discovery

of the original Money Pit.

The dates are
well, well before any searcher

should have been
in this area tunneling.

I think that's in everybody's,
you know, vision right now

to deepen that Garden Shaft
and find out what's down there.

You have a tunnel,
previously unknown,

heading in the direction

where these high metal
values are being derived.

So, if this is original work,

then you're a small step closer

to the ultimate solution.

We have every reason
to continue the process

of trying to understand
what this tunnel represents.

- We have to get down there.
- No, absolutely.

And that's pretty well our next
step, where we're at right now.

Just getting to it, exposing it.

I think it's going to
answer a lot of questions

that we-we have right now.

- Yep.
- These results tell me you need to work faster.

Yeah. Yeah.

Okey doke. We'll let
you get to work, Roger.

- Thanks, Roger.
- Very good.

Thank you very much, gentlemen.

Great news.

The following morning...

as representatives from
Dumas Contracting Limited

continue deepening
the Garden Shaft

in order to breach the tunnel

at a depth of some 95 feet...

- Hey, Billy.
- Hey, guys.

Ready to keep rolling, mate?

Keep rolling,
Gary, I think. Yep.

Got a lot of water in the hole,

but we can see the
rock a little better now.

Jack Begley
and metal detection expert

Gary Drayton join Billy Gerhardt

in the southeast
region of the swamp,

just north of the potentially
500-year-old stone road.

What is the swamp
battle plan today?

We'll go a little more
back towards the road.

And do the same
thing, we'll reach out,

and then continue back
towards the peninsula.

All right. We'll get
ready to get stuck in.

- Okay.
- Hopefully not literally.

Billy, Gary and Jack are eager

to confirm the potential
breakthrough discovery

they made two days ago

of yet another man-made
stone pathway in the swamp,

which appears to be leading
toward a massive boulder.

This is where the
real fun is, Gary.

Yep.

See if we get lucky.

We have found
all of these structures.

They imply purpose, intent.

To me, there's only
two trains of thought here

to try to explain the
why of the structures

found in the swamp.

One, they were
ancillary to other work,

whether that be in the
Money Pit or elsewhere.

Or two, there was depositional
work in the bog proper

and these facilitated that work.

Let's see.

I think we've got
a bit of planking here.

Yeah.

Yeah, yeah, definitely planking.

Look, it's got that like tongue
and groove effect going on it.

- Yeah.
- Wooden planking or siding.

- That looks intentional to me.
- Yeah.

- More bits of the ship.
- Yeah. For sure.

Good eye, Gary.

Look how deep it came out of.

Look on the other side, too.

- Yeah.
- Tongue and groove.

Does that go back
quite a long time?

Yeah.

All right.
I'll set it aside.

Okay, mate.

We're finding a lot
of decking or planks,

which is very interesting

because we are actually
way out in the swamp.

Are these planks, these
decks part of a mystery ship

waiting to be found
in the swamp?

That would be
absolutely unbelievable.

It's still sloppy.

I hear
clanging. Is he hitting rocks?

Yeah. He's
got a rock in his bucket.

Yeah, it's a lot of rocks
in line with that big rock

and the shore, but to
the side there's none.

Yeah.

If you watch where
I put my bucket,

to this side...

you know, it's-it's
nothing there.

But in here...

Yep.

I think it could be
some type of ramp,

leading up around here.

- Yeah.
- It could be you're right.

A ramp for something big.

This is gonna be good.

- Hey, guys.
- Hey, Rick.

- Anything?
- Billy feels like

he might have found
some other structure.

It's just hard to see
underneath the muck.

Yeah.

Billy, why don't you tell him

what you feel like you can feel?

It's a lot of rocks in
line with that big rock.

But as we move this way,
there's no stones at all.

Yeah.

After being
alerted that more of a possible

stone ramp, which may be
connected to a large boulder,

has been uncovered in the
southeast corner of the swamp,

Rick Lagina joins Billy
Gerhardt, Jack Begley

and Gary Drayton
to help investigate

the curious feature.

A little bit of mud
on top of them,

but they're most
definitely there.

Yeah.

And this
boulder is about the size

of some of those other
Nolan's Cross rocks.

Yeah. Definitely conical shape.

A cone-shaped
boulder in the swamp?

And similar to those
in Nolan's Cross?

First identified in 1981

by the late Fred Nolan,

Nolan's Cross is a
perfectly symmetrical,

megalithic formation
of six boulders

near the center of Oak Island.

Over the years,

numerous researchers
have speculated

that the cross is a
symbol indicating

that the hidden
treasure includes

priceless religious artifacts,

such as the Holy Grail.

Nolan's Cross may lead
us to a Money Pit location

and where the treasure might be.

And others,
like architect Brian Pharoah,

believe the feature
represents a treasure map

which points to the location

of buried valuables
in the Money Pit area.

You've got to dig on that
side of it and this side of it.

Because then we can
shovel it off and take a look.

Yeah.

Could this cone-shaped boulder

and the possible stone ramp

be related to Nolan's Cross?

If so, might they
represent clues

that are connected to high-trace
evidence of precious metals

that have been detected
in the Money Pit?

Or could it be related to
valuables that are buried

in the triangle-shaped swamp?

I would like
to know definitively

that the constructs
within this body

of the bog are
related to the mystery.

Is it perhaps associated with
original depositional work?

My hope is that as
we excavate the ramp

in association
with the stone road,

we will hopefully

find some artifacts that will
help with that explanation.

It fits all the parameters.

It's big enough to step on

and it's right at the
interface between

the muck and the water.

I mean that's like a
Nolan's Cross boulder there.

Yeah. We may have
discovered something

really important there, mate.

Just got to work
on it, clean it off.

There's no question
it's pretty unique.

When you see all the
digging we did today, there's

something going on there, so...

- Yeah.
- Yeah.

If there's a ramp, you know,

there's a possibility of...

defining it and
looking for artifacts, so

that might be an "aha" moment.

Yeah.

So keep digging
and see what we see.

Okay.

Later that afternoon...

- Thanks, Jack.
- Come on in.

At the Interpretive Centre...

- How's it going, Laird?
- Hey.

Hey, how are you?

- You called?
- I did.

Rick, his nephew Alex, Jack

and Scott Barlow meet with
archaeologist Laird Niven

and archaeometallurgist
Emma Culligan for an update

on the concrete-like
substance that was unearthed

two days ago in the
stone foundation on Lot 5.

So, this is a soil sample.

Soil that Jamie
thought was mortar.

And it was

important enough we
thought to compare it to some

- of the mortar that we are getting in the Money Pit.
- Yeah.

And Emma has the
results of the comparisons.

Great.

In order to analyze

the believed
concrete from Lot 5,

Emma has scanned it with
an X-ray diffraction device...

Or XRD... which uses
X-rays to determine

the chemical composition
and physical properties

of materials.

So, I compared it to mortar
samples that I have on file,

and it did not match,
so it's not mortar.

And it had some
differences to...

other soil samples
collected from Lot 5.

So I ran a comparison to...

the entire soil database
that I have so far.

And on the screen, you can see

a cluster diagram that I have

of the main soil samples.

And our sample in that grouping,

it's an almost exact match

to a Money Pit sample
at a depth of 104 feet.

Wow! That's great.

So, which borehole did this
come out of in the Money Pit?

So there's a few.

C-28, C-18.5,

and also the Garden Shaft.

- Okay, great!
- Wow.

Amazing.

That's close to our tunnel

below the Garden Shaft.

Explain that.

This soil sample taken
from Lot 5 matches with...

Money Pit soil samples
found near the Garden Shaft.

- Okay, great! -Wow.
- Amazing.

It is a potentially
critical moment for Rick Lagina

and members of
the Oak Island team.

I should
point out that the little,

tiny piece we
thought was mortar,

it's not natural.

So it's not naturally occurring.

So it must have been replaced
there is what you're saying.

- Yes.
- Exactly.

Archaeometallurgist
Emma Culligan has

determined that a
mysterious type of artificial soil,

which was recently unearthed
in the stone foundation

on Lot 5, matches others
that have been collected

by the team some 100 feet deep

in the Money Pit area.

And in the same region as
the possible treasure tunnel

located several feet
below the Garden Shaft.

We're always looking
for a connection between

Lot 5 and the Money Pit.

Didn't think we'd
get it from the XRD.

- Yep. Well, this is an exciting possibility.
- Yeah.

And if we think about
the interpretation

that we are most
interested in, that would be

somebody physically transporting

the same soil from
one to the other.

- It doesn't matter which way.
- Yeah.

Yes.

Then this might show
that the Lot 5 feature

was somehow related
to the early excavations

- or the deposit of the treasure.
- That's the hope.

Yeah, that's one thing
we've been looking for on the island

is evidence of people staying
here while they did the work.

- We haven't found that at all.
- Yeah.

We know that the last
reports that we've got on

the wood samples
from the tunnel,

there is a strong possibility

that it was pre-searcher
from the 1600s.

- Which would be huge.
- Which would be huge.

- Yeah.
- Those dates

do work pretty well
with the Phips theory.

Abso-Absolutely.

Phips was in the area.

Yep.

In early 1687,

the English Naval Captain
and politician William Phips

recovered approximately 34 tons

of treasure in the Caribbean
Sea from the famed Spanish wreck

known as the Concepción.

Later that year, King James
II of England knighted Phips

for his achievement

and ordered him to
conduct a second operation

to recover the nearly
65 tons of valuables

that were believed
to remain on the wreck

according to its manifest.

Phips made the journey
with the help of a Freemason

from Nova Scotia
named Andrew Belcher.

But curiously,

they returned with less
than two tons of the riches.

I see it as a possible
link between Lot 5

and the Money Pit and I
think we should try to prove it.

Yeah. Absolutely.

Could Alex Lagina be correct

that the matching soil samples

from the foundation on Lot 5

and the area around the
potentially 17th century

tunnel beneath the
Garden Shaft offer evidence

that Phips hid the
majority of his discoveries

from the Concepción
on Oak Island?

Here we have a
very interesting connection.

I can't deny it.

With these specific timelines

and the significant
interest in Lot 5...

one could make the association

to the salvage of
the Concepción.

And it could change
the way we perceive

the relationship between
Lot 5 and the Money Pit.

But until we get

to the bottom of the excavation,

I think every possibility

is on the table at this point.

That's why it's
incumbent on us to

figure out what
this structure was.

- Yeah.
- Absolutely.

The association
that could be made

is potentially mind-blowing.

Let's just stay the
course and move forward.

- Okay. Thanks, Laird.
- All right.

- Thanks, Emma.
- Thank you, Laird.

- Thank you.
- See you later.

After more than a decade

of tireless work
and perseverance

through numerous
unforeseen challenges,

Rick, Marty and their team

may be closer than ever
to unearthing the answers

that many before them
were unable to reach.

As they dig deeper
into the swamp

on Lot 5
and below the Garden Shaft,

will they finally reveal
not only

what lies hidden on Oak Island,

but also the truth behind

this 229-year-old mystery?

Or could
the next major discovery

that they make
unleash a deadly curse?
