All language subtitles for The Curse of Oak Island - S12E04 - Concrete Evidence WEBDL-1080p.mkv

Tonight on
The Curse of Oak Island...

So, this is the Golden Egg,

where precious metals
are coming from.

It could literally be gold.

Could be. We're due for a win.

The Restalls were convinced

that they found the flood tunnel
down in Smith's Cove.

If there's something here,
we should find it.

- It's cement.
-Wow, there's
a chance we've hit

the flood tunnels?

I did do a CT scan
of the surface image.

- What do you think that is?
- It's related to gold.

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.

So, here we go.

We cover this ground properly,

then we know it's not here
or we bump into something

that everybody's been
hoping to find, for what,

- 200 years?
- Since 1795.

for brothers Rick and Marty
Lagina and their team

as they continue investigating
the fabled Money Pit area

in search of the answers

to a 229-year-old
treasure mystery.

As we have it
plotted on our map,

borehole FN-15.5,

this is towards the southern end
of the Golden Egg...

- Yeah.
- ...where Fred believes
the precious metals

- are coming from.
- Yeah.

So, I mean, today could be
a really important borehole.

- The possibilities are endless.
- Yeah.

-Good morning, Rick.
Good morning, Alex.
-Good morning.

a new strategic
core-drilling operation

in a 30-by-15-foot area
dubbed the "Golden Egg."

It is here where recently
conducted groundwater testing

has detected
an unnaturally high source

of precious metals between
depths of 80 to 120 feet.

You felt like
you just caught something?

Well, it was really soft
at the top here.

disturbed soils were recovered
from nearly 100 feet deep,

suggesting that a large
man-made structure or object

could be buried nearby.

This whole area

needs to be explored,
because those metals

are coming from somewhere.

Yeah, it could
literally be gold.

- Am I right?
- You are right.
- Could be.

located just 14 feet
to the northeast,

in the hopes of pinpointing
the possible man-made feature,

and hopefully, a vast cache
of precious metals.

This one particular hole
has the possibility

of being highly informative.

Dr. Fred does believe

that these metals
are highly concentrated

in the Golden Egg,
and because we may have hit

a flood tunnel in the area,
we could be close

to actually finding
the treasure.

And let's not forget,
y'all remember last year

when Dumas was probe-drilling
at the bottom

of the Garden Shaft.

We hit a potential flood tunnel,

and I mean, we had hundreds
of gallons a minute.

And we're a mere, well,
you can see it, five, ten feet

off the north corner
of the Garden Shaft.

There was 700 gallons
a minute of seawater--

not fresh water, seawater--
coming into that Garden Shaft.

Yeah.

began drilling
into a mysterious tunnel

located some 100 feet deep below
the 18th-century Garden Shaft...

causing the team
to abandon the operation.

This disastrous setback
has made them speculate

that they encountered
the legendary flood tunnel,

reportedly made
of large cobblestones,

and which is believed
to originate at Smith's Cove.

If that's the flood tunnel
coming from Smith's Cove...

- Yeah.
- ...we know the flood tunnel
went directly to the Money Pit.

So, if we could follow
that tunnel,

we'll know where
the Money Pit is.

We still got about 60 feet to go

before we get into
that horizon of interest.

- We're due for a win, Terry.
-Yeah, absolutely.
Here's hoping.

continues in the Golden Egg,

later that afternoon...

interesting efforts this year.

- Mm-hmm.
- Yes.

and operations manager
Scott Barlow

meet with Marty Lagina
and surveyor Steve Guptill

in the research center.

Look, everybody knows

there's unfinished business
down in Smith's Cove.

So I think we need
an additional dig down there.

And I'm gonna turn it
over to you, Scott,

because you have made
a very astute assessment

of what you want to find.

So, why don't you
fill everybody in?

So, basically,
let's-let's rewind back

to last year
with the Dumas shaft.

They were drilling out
of the bottom of the shaft,

and then, uh, you know,
we had salt water rush in.

Yeah, we did.

We looked back at the history.

The Restalls
really felt confident

that they found the flood tunnel

that caused all the grief
for all the years--

there were people
trying to retrieve treasure

- out of the Money Pit.
- Mm-hmm.

former motorcycle daredevils
Robert and Mildred Restall

moved to Oak Island with
their sons 18-year-old Bobby Jr.

and nine-year-old Ricky
to pursue Robert's dream

of solving the mystery.

Living in small cabins with
no electricity or plumbing,

they braved the elements
for more than five years,

while focusing their efforts
at Smith's Cove.

There, they worked by hand

to find the so-called
convergence point,

where five stone box drains

formed a single flood tunnel
connected to the Money Pit.

But on August 17, 1965,

while working
in a 27-foot-deep shaft

that he believed was close
to reaching the flood tunnel,

Robert, along with Bobby
and two other men,

tragically lost their lives

when poisonous
hydrogen sulfide gas

mysteriously emitted
from the bottom of the pit.

The real tragedy of
the Restalls' work, obviously,

was the passing
of the four people.

But they were convinced,

as you have said,
that they had locked into it.

Yep.

You'll see on the diagram
Steve has up here,

it's-- this is the Restall map
overlaid on all the data,

basically, that we have
in Smith's Cove.

Right where he has
his cursor right there

is the convergence point,

what they felt
was the convergence point.

The "convergence point,"
meaning-- being...?

They uncovered what they felt
were finger drains right there.

And they believe they followed
those finger drains

to a convergence point,
which they believe

led to the flood tunnel
that led to the Money Pit.

So, here's the convergence point

that the Restalls
denote in 1963.

One thing I really like
is that if I project that line,

it projects through
to the Garden Shaft,

and so, potentially, it could be
what we tapped into last year.

The one issue is,

their convergence point
is right where

high tide is along the shore.

So, unfortunately,
we can't dig on that spot.

So, we're gonna have to come
upland a little bit of it

and my hope is we're gonna
find some of the tunnel.

Yeah.

the convergence point

is down at tidal level.

The environmental laws say
you can't, you can't dig

without a very specific permit.

We don't have a permit
to dig there to actually find

the convergence point.

Okay, where do you want
to dig, Scott?

We can start on
the inland side of the road,

so it'll give us
a little bit of a buffer there

between the shore and that.

So, digging in a new area
down there,

I suspect we're looking to
find a lot more.

We're also near the area
where the Restalls

found what they called
a "vertical shaft,"

which they believed
led to the flood tunnel.

They tried to stop the water,
and they came up with a plan

where they were pumping concrete
into this hole in the ground,

basically,
that went vertically down.

When they started
pumping the concrete,

the water started to slow
in the Money Pit.

Robert Restall Sr.
and his son Bobby Jr.

were astonished
when they uncovered

what appeared to be
a one-and-a-half-foot diameter,

32-foot deep, stone-lined shaft

on the beach at Smith's Cove.

It was Robert's belief

that the so-called
"vertical shaft"

was created by the original
treasure depositors

as a way to shut off

the flow of seawater
into the Money Pit

in order to access
the buried valuables.

In an effort to clog
the flood trap,

Robert mixed concrete
and poured it into the shaft.

But unfortunately,
most of the mixture

did not properly set,

and failed to stop
the water flow.

So, the-the hope
with this would be

to potentially find
the remains of concrete

or something there to know
that we're onto the right spot.

Bottom line,
this is eminently worth doing.

Let's make it so.

We have a plan. Let's dig.

conclude their meeting
in the research center...

-So, is this
the spoils pile right here?
-Yeah.

This is the latest one
that Billy's guys moved around.

...Craig Tester
and metal detection expert

Gary Drayton arrive on Lot 4,

located on the western side
of the island.

All of this stuff came from

- the round feature behind us.
- Oh, okay.

through more than
ten tons of spoils

that were removed one year ago

from a mysterious
rounded stone feature

located several yards
to the east on Lot 5.

A feature where, in addition
to a mortar-like soil

that may have come
from more than 100 feet deep

in the Money Pit area,

the team has unearthed
a number of stunning artifacts,

including a fragment
of a 17th-century

English silver coin,

and a 14th-century
lead barter token

which, like the lead cross
that was discovered

at Smith's Cove in 2017,

may be connected
to the medieval order

of the Knights Templar.

Let's see what
we've got waiting for us.

Oh, nice little

- signal here.
-That sounds good.

That looks easy digging,
right in the rock.

- Okay, we'll start...
- Well, actually,

it's gotta be on top
of the rocks, in the soil.

It's so small there.
Why don't you hit it

with your, uh, pinpointer?

Yeah, I'll try to pinpoint it.

Oh, I moved it.

Oh, I see it.

Oh, wow, look at that.

Wow, this is fantastic!

Oh, wow, look at that.
It's copper?

from the mysterious
round feature on Lot 5,

Craig Tester and Gary Drayton

have just made a potentially
important discovery.

It's a nice little button, mate.

- Oh, right.
- Look at that.

Nice. Very round.

Does that mean anything to you?

Yeah, these rounded buttons
were normally tunic buttons.

Okay.

Loop's still on it, isn't it?

Yeah.

Time period?

Could be late 1600s to mid-17s

because it is a fancier button.

This is unusual.

- We haven't found any of those.
-Yeah.

If Gary is correct that it may

date back to the 17th century,

could it be connected
to the cut English coin

that the team recently
found in the spoils

from the round feature on Lot 5?

And perhaps also help identify

who created
the original Money Pit?

That's a nice little button.

It'll be interesting once
they clean it up,

- what they see.
-Yeah.

All right, mate,
we'll put this in the bag.

Another great little find.

Whenever we find a button,

I get excited because
I know there's a chance

of getting some
military insignia,

which will hopefully
help the archaeologists

track down what has been
happening on Lot 5,

and hopefully the Money Pit.

Oh, nice little

- signal here.
- Again?

And it's just there, mate.

Okay.

Sounds like a nonferrous hit.

It's out.

Great sounding signal.

Let's see what we got.

What have we got here?

What have we got here, Craig?

That feels like lead.

I think I know
what that is, mate.

I think that's a coin weight.

- Oh, really?
- That looks--

Yeah, that looks like
an old coin weight.

You see how it's been
sloped down on four sides?

That's what they used to do.

Slope 'em down
and cut pieces off to...

- to weigh coins.
- Okay.

Your average person
wouldn't have one of these,

- would they?
- It would be someone,

kind of higher up.

It would've been the person,

like, in charge of the payroll.

- Mm-hmm.
- I would imagine that

that is an older style.

I mean, coin weights go

way, way back,
before Roman times.

But they went out of fashion,
probably, in the 1700s.

Oh, okay.

So, this could be
an old coin weight.

the weight of a coin
would often vary.

Coin weights
were used by merchants

as far back as 305 BC

to ensure the true value
of the coins

they received, as well
as prevent counterfeiting.

Is it possible Gary and Craig

found a lead coin weight?

If so, might it have been used

to divide up sums of treasure,

and perhaps be related
to the high concentration

of precious metals
that have been detected

in the Money Pit area?

That is really, really cool.

Well, we'll have to see what
the archaeologists think of it.

Yeah.

I'll put it in the bag.

There.

All right, mate, good digging.

- Okay.
- All right.

To continue.

Now, hopefully, we can find

- a gold coin.
- Sounds good.

as the core-drilling
operation continues

in the Money Pit area...

This is why
I didn't bring a shovel.

My kind of shovel, as well.

and other members of the team

arrive at Smith's Cove,

located nearly 500 feet
to the east.

All right, guys.

So, Steve's pinned
a spot on the ground here.

X marks the spot, eh?

that was created in 1963

by the late treasure
hunter Bobby Restall,

they have chosen a location
just inland from the beach

where they will
attempt to uncover,

and cut off, the flood tunnel

that is believed to feed
seawater into the Money Pit.

For the purpose of this,

we want to look
to see if we can find

- the flood tunnel.
- Yep.

So, the great thing
about this area is

when the Restalls followed what
they believed they were chasing,

which was the finger drains,
they found, more or less,

a vertical shaft,
and they believed

that it went inwards
in the flood tunnel,

because that's where
the water came in.

And the Restalls

pumped a lot of concrete
down there.

They were trying to stop
water there with cement,

and it blew out on them.

- Oh.
- So the hope is

that when it blew out, it blew
back into the flood tunnel,

and we're going to find
some evidence of that.

- Yeah.
-Any idea about depth?

30 to 40 feet.

If it's 30 to 40

feet deep, we're not
going to be able

to get it with the excavator.

No, we have
the long reach, though.

So, Billy can start
with this machine.

-Yeah, makes sense.
-Well, Billy Buckets,

let's make some
treasure headlines today.

- I'll get ready for the spoils.
- Okay, Gary.

We're ready.

such as stones or boulders
covering the flood system,

Billy Gerhardt
will begin digging

with a 14.5-ton excavator

to clear them away.

Then, he will use
a 35-ton long-reach excavator

capable of reaching
a depth of some 60 feet,

to hopefully locate
the believed flood tunnel.

200 years of it has been about

the water in the Money Pit.

The inability of people
to control the water

in order to retrieve
the treasure at depth.

If we can find
the flood tunnel itself,

then the next step

would be to shut off the water.

Water's coming in

from the land side.

Right here. You can
see it coming in there.

Yeah. I guess it could be

coming in from
both sides, really.

Oh, yeah, it is coming in
from both sides. For sure.

We're making
pretty good progress.

Looks like we're about halfway

- where we should hit
the flood tunnel.
-Right.

later that morning...

Hey.

- Hi, guys.
- Hello.

-Good morning.
-Good morning.

...Gary Drayton
joins Rick Lagina,

archaeologist Laird Niven

and archaeometallurgist
Emma Culligan

in the Oak Island Lab.

Rick and Gary are eager to hear

Laird and Emma's analysis

of the button and
possible lead weight

that were found
in the Lot 5 spoils

just one day ago.

What about the button?

- Any info on the button?
-Info on the button.

I did do a CT scan,
but that's obscuring

the surface image.

Earlier today,
Emma scanned both artifacts

using the Skyscan 1273
CT scanner,

a device which emits X-ray
radiation to produce detailed

three-dimensional
images of objects.

Additionally,
she also scanned them

with the X-ray fluorescence
spectrometer, or XRF,

to determine the elements
that make up their composition.

It's a copper-iron alloy,
and it does have

a high content of lead in it.

No aluminum, so that's good.

There's no severe indicators
that it is modern.

- Okay, good.
- Yeah.

So, I would fit the composition

to 1700s to early 1800s,

- English.
- Hmm.

So, this is the best
image I could get.

I think what it says

is it points more
towards a gentleman

than a farmer, again.

Yeah, yeah.

And that could
tell us something about

what the round feature
was used for.

We have a lot of questions left

about the round feature.

I think what we're finding now
supports several of the theories

that ties the deposition
of something on Oak Island

by the British military.

I feel that's where the evidence
we have on Lot 5 is leading us.

Okay, the next one.

Yeah, I think that's
probably the most interesting.

What do you think that is?

It's lead.

It weighs 26.2 grams.

Gary thought
it was a coin weight.

Whenever you find a shaped
piece of metal like this,

especially if
it's bronze or lead,

it's usually a coin weight.

Now, this is large,

but I was thinking
maybe it's a weight

for a large coin.

It would be a very large coin.

When you say... when you say
very large coin, what?

Well, the largest coins

back in the day,

uh, would've been gold.

Maybe it's a weight
for a large coin.

The largest coins
back in the day,

would've been gold, right?

archaeologist Laird Niven

has just suggested

that the lead artifact that came

from the mysterious
round feature on Lot 5

may have been designed
to weigh coins of great value.

So start looking
at big gold coins

- 'cause that would be great...
- Oh, yeah. Yeah.

...finding one of those
on Lot 5.

It'd be a big coin.

Emma has
a dissenting opinion about it.

Oh, okay.

So compositionally,

I do think it's modern.

The phosphorous content,

it's extremely high
and you don't see that

in lead alloys
until mid-20th century.

However,

I don't, you know,
lead isn't my...

- Wheelhouse.
- Yeah, wheelhouse.

So we have a conundrum
because I think

the problem with it
being modern is

we're not finding
other modern artifacts on Lot 5.

It really does look old.

-Yeah.
-I mean that looks
really nice and old.

Yeah. I mean,

lead was used for coin weights,
but early on, too.

- Yeah.
- Like earlier,

- and then replaced
by, uh, brass.
- Mm-hmm.

there seems to be a transition
from lead coin weights

to brass coin weights
somewhere after 1066.

If we can prove that this
trade weight is very old,

it puts the other old coins
we're finding on Lot 5

into a more clearer perspective.

Emma's analysis is suggesting
the lead weight is

more recent
than the archaeologists think,

but this is

a point where we
need to, uh, consolidate

the archaeology
and the science together

and come to a new understanding

of what this artifact is.

So I do think that it is
an excellent candidate

for laser ablation.

Great. That's what
I was gonna say.

-Yeah.
- It's fantastic.

that uses a high-powered laser

to remove a microscopic sample
from the surface of objects

that are composed of lead.

The sample is then analyzed

to determine
its specific isotope value,

which can reveal not only
where the object may have

originated but also
its approximate age.

Well, I think we can
follow this up in two ways.

The laser ablation

and finding an expert or experts

- to weigh in on this.
- Mm-hmm.

It's a very curious find.

It feels right in your hand
for some reason.

- It's up to you, Gary.
- Yeah.

Well, we got to find
some more stuff.

- We got to find some more stuff.
- Yeah.

We have to exhaust

the reach of the excavator
before we move on.

proceeds at Smith's Cove...

- Whereabouts are we?
- Just about to bring up the...

in the Money Pit area
to check on the progress

of the core-drilling operation

in borehole FN-15.5.

The next core or two is really
gonna tell a story.

Ninety-nine.

It's looking
relatively competent.

Nothing there.

Ah...

It's competent,
but it is a little soft.

We still got another ten feet

where we could hope
to see something.

Yep.

We have a core.

it's the closest we've ever
drilled to the Garden Shaft.

So the possibility

not only of treasure
being here but perhaps

intercepting the flood tunnel.

There's something
going on in this area

that may be associated
with a deposition of treasure.

You have to be very observant.

- 109.
- 109.

It looks pretty in situ.

Nothing to write home about, unfortunately.

I see no structure.

Unfortunately,
I don't see anything.

We were hoping
to find something

in the Golden Egg that would say

there's something there
at that depth.

We haven't found it yet.

But I-I emphasize "yet."

There's still a high confidence
that something exists

in these areas
that they have delineated.

We just got to keep going.

On we go, for sure.

in the so-called Golden Egg...

Hey.

I'll give you this, Peter.

I'm pretty proud of you
for sitting out here

in this kind of heat.

where Billy Gerhardt
is now using

the massive long-reach excavator

in the hopes of uncovering
the legendary flood tunnel

that is believed to feed
seawater into the Money Pit.

We're probably at depth
about seven feet away.

So I think we could be
in anything, any time now.

Okay, well, then it's just

a matter of keeping
an eye on the ball.

- Right?
-Yeah.

seawater, being
artificially introduced

through a man-made tunnel,

we perhaps can track
that tunnel back

to "X marks the spot"
in the Money Pit.

That's the important
aspect of this,

of this particular endeavor.

There's a lot of cobble
in that one.

-Yeah.
-All kind of uniform.

And that's the description
of the flood tunnel, right?

Uh...

about the size of a,
of a human head,

you know, packed in.

So, there's a chance
we've hit the flood tunnels?

-That is the description.
-Of the flood tunnel.

So there's a chance,
we've hit the flood tunnels?

This is the first bucket

that has a bunch
of same-size cobbles.

Rick Lagina and other members
of the team

have just uncovered
large cobble stones

more than 30 feet
below the beach.

Yeah. That is
a good observation, Rick.

of the believed
man-made flood tunnel

designed to protect
the Money Pit treasure vault.

They're all roughly
the same size.

That.

That. That.

This.

This.

- Yeah, those rocks are
as big as heads.
- Yeah.

That is the description
of the flood tunnel.

Packed with stone.

Yeah.

The tunnel was
three foot by four foot.

Packed with stones
the size of a human head.

And, and look
at how many there are here,

- just right here.
- Yeah.

And look how sloppy this is.

- There's a lot of water
coming in.
-Exactly.

- The cobbles should
extend the whole way.
- Yeah.

Because they didn't want it,
you know, closing off,

so it should be
packed with stone

all the way to the Money Pit.

That's the first bucket
that we saw that...

Let's come over
on this side, Rick.

Can you see where I took
that last bucket?

You see where the water's
coming out down the hole?

Yeah.

That's, that's where
the rocks came from.

But if you scoop there,
that ground is pretty cobbly.

It's almost like,
it looks like, that was dug out.

Yeah.

than to confirm

the old narrative, i.e.

that there are box drains

and a flood tunnel system
that might lead

to a chamber or a void,

or a place
where treasure was deposited.

The Restalls were
onto something in Smith's Cove

and that something might help us
as we put X's on the ground

in the Money Pit
for the caisson work.

I think we should

take a scoop there
and maybe have Steve come down.

I would dig wider on both sides
and see if more cobbles come up.

If we found the same cobbles,
that'd be interesting.

But we still have
to clean it out deeper

because that's the line there.

-Yeah.
- So, we got more work to do.

as a sudden rain storm
has caused the team

to temporarily halt
the dig at Smith's Cove...

We got a core.

Alex Lagina
and members of the team

continue their strategic
core-drilling operation

in the hopes of locating
the source of precious metals

that have been detected between
80 and 120 feet underground.

No gold,

no treasure chamber can
evade us.

We have to be sure
that we've covered the ground

and that's what we're doing.

borehole GN-16 located

in the so-called Golden Egg

and just 13 feet north
of the Garden Shaft

where the team encountered

a possible flood tunnel
one year ago.

You okay?

where we have
very few boreholes.

So that's exciting to me
because this is

fresh ground, fresh territory

with a,
a very plausible indication

that there might be
treasure buried here.

109.

- 109.
-Thank you.

GN-16. 99 to 109 in front of us.

Let's see what we got.

Sadly, it's a little firm.

Not really terribly impressed,
I wouldn't say.

No water passage at this point.

On the flip side,
what did they drill into

to cause
the Garden Shaft to flood

if this can't transmit water?

It's got to be
a structure, then.

The-the evidence
tends to lean that way.

I'd certainly love to perforate

- that structure...
-Yeah.

- Absolutely.
-...and get some

empirical evidence
of its existence.

This is great stuff
to tunnel in.

Yeah.

- Hi, Craig.
- Hey. How deep?

- 119.
- All right.

- Anything above it?
- Nope.

Soft or anything?

- Nothing.
- Okay.

- Thanks, guys.
- Still seeing, you know,

usually it falls open

and it's all saturated.

-129 or 119?
-119. I got...

This has a little bit of sand,

but there's still
some silt in it,

so it wouldn't carry much water.

Is it soft enough to indicate

that we're next
to a tunnel or shaft?

No, it doesn't give us
an answer or a solution.

I think I'd call it quits.

I'd rather get moving
to the next location.

hard evidence
of the precious metals

that have been detected
in the Golden Egg,

they still have
nearly 200 square feet

of the area to investigate.

that there are
concentrations of metals

in a very well-defined area
that may lead to a treasure.

Unfortunately, the results
have been less than positive,

so I'm a little disappointed.

But we're not
giving up on finding

whatever this thing is that's
gonna come out of the ground.

I'm gonna head on out
and, uh, talk to Dr. Spooner.

Talk to you guys later.
Give me a call.

-Okay, yeah,
we'll keep you posted.
- Okay.

Onward and downward.

Well, guys, we all know
that we've followed

the water sample
testing protocols

to try to determine where
to find the "treasure," really.

And, uh, Ian and Fred

proposed the so-called
Golden Egg area

we are currently drilling.

geoscientist Dr. Ian Spooner

has asked to meet
with Rick Lagina,

Craig Tester
and other members of the team

after conducting
new groundwater testing

for precious metals
in the so-called Golden Egg.

Ian has some serious concerns
about progression

of the drill program
and-and where we locate it.

And so, Ian, I'm gonna
turn it over to you.

So, the water samples
I've taken in the Egg,

we-we haven't seen any data
at all for precious metals.

That's the challenge
we're facing.

So, why? Because this anomaly
we're chasing is precious metal.

And the metals
accumulate in the water

because it's probably
coming from

the bottom of a shaft
or a tunnel,

where it is sealed,
quite nicely.

And so, the problem
with just continuing

to drill in the Egg is,
when we do penetrate it

with a drill,
that water disseminates.

That anomaly disseminates.

We call it, in my world,
a dispersal plume.

And so, our worry
is if we continue to drill,

if something is happening there,
uh, we could dilute it.

We could confuse ourselves.

refers to small particles
contained in water,

in this case, particles of gold,
silver and other metals,

that are possibly
being stirred up and spread out

by the team's
core-drilling operation.

This makes it difficult
to detect

just where
their ultimate source,

such as a treasure chest,

may be located within
or near the Golden Egg.

What does that mean
for the drill program?

- How do we proceed?
-Well,

we'd like to stand down on
drilling in that area right now

and let this site
sort of settle, if you will.

You want cessation of drilling
within the Golden Egg.

Yes.

We'd like to send in
those new water samples.

We'd like to see
what those samples show,

and then be able
to look at the data.

And give you folks a sense
of what the potential is,

if we do
do further drilling there,

for some kind of success.

Yeah.

Well, I think we have
to do that, because otherwise,

there's no point
in chasing the data.

-Yes.
-Yeah.

are suggesting that we cease
drilling activities

in the area of the Golden Egg

because we don't want
to dilute the water,

and every time
we put a hole down,

you're introducing water
as part of that drill program.

So, we need to gather
more evidence

to actually bingo
where a treasure might reside.

Hopefully, the doctors
can look at all of the samples

we obtained and come back
and say, "Hey guys, we found it.

Here's where you need to look."

So, yeah. That's where we stand.

- Okay.
- I think we've all

- got work to do.
- Yeah.

-Okay.
-Okay. Thank you.

-Is that another timber?
-Oh, it is, yeah.

Eyes and boots.

That's what it takes.

while searching
for more evidence

of the legendary flood tunnel,

Rick and other members
of the team

have unearthed a number
of mysterious wooden planks.

It is amazing how these boards
are all the same dimension.

Wow, you really are
the chairman of the boards.

Where do you think these pieces
of wood come from, Rick?

Certainly no later
than the Restalls.

Yes. Maybe they just...

- repurposed them.
- Maybe.

I-I don't find it unreasonable

that they would, you know,
take whatever they found

in order to facilitate the work
they were trying to do.

If they found something,
an old shaft or something,

and they were doing work
on their own,

- you know they would salvage
whatever they could.
- Yep.

where the Restall family
believed

that the legendary flood tunnel
that feeds seawater

into the Money Pit
might be located,

could Rick be correct
that they used this lumber

as part of their efforts
to stop the booby trap

more than 50 years ago?

Or could it
have been placed here

by whoever created
the flood tunnel long ago?

Billy. Hold up.

What do you make of that?

- Cement.
-Yeah.

Wow.

This could be connected
to the flood tunnel.

-Cement?
-Yeah.

Gary, Peter.

while searching
for a man-made flood tunnel

that is believed to divert
seawater

into the Oak Island Money Pit...

What have you found, Rick?

Well, you know what
we've been looking for, right?

The story of the Restalls
pouring cement.

a potentially
significant discovery.

- Is it concrete?
- Yep.

-It's good eyeballing.
-Mm-hmm.

I would remind you
that the Restalls,

when they tried to shut off

the supply, if you will,

of water for flooding
the Money Pit,

they poured concrete
down into the shaft,

and then, supposedly,
it let loose.

that he has found
a piece of the concrete

that Robert Restall made
more than 50 years ago

in an attempt to clog up
the vertical shaft?

If so, might it offer
more evidence

that the team is close
to uncovering the booby trap

that leads directly

to the fabled
Money Pit treasure vault?

To find concrete

in the area of the associated

flood tunnel line,
well, that's exactly

what we're looking for.

And if we can find it,
actually find the tunnel

and put eyes on it,
then we can try to do

what they tried to do:

shut off the water
once and for all.

- I think we need to
take that to Emma.
- Mm-hmm.

Maybe put it in the XRD
and she could,

from an analysis perspective,
determine

- how old that type
of concrete is.
- Mm-hmm.

It's definitely worth
testing for sure.

What it says is
that there's a possibility

that there's more
and we should definitely

keep our eyes open
for it because

you're not gonna
find it with that.

- No.
- Unfortunately.

It's gonna be
the twin optical scanners.

Well, think about
what this may mean.

We're doing sonic drilling
in the Money Pit.

We're looking for locations
for the caissons.

We're trying to prove
the old story.

The old story leads

to an increased belief

that there was
a flood tunnel system.

The flood tunnel system,
if we can delineate it,

will lead us to the Money Pit.

The Restalls started
this process

and we need to finish it.

When you endeavor
to do something

and you make a commitment

with something that is
that impactful

that this young man
and his father

and two others
lost their lives...

if you can't tie into that,

that sacrifice,
the ultimate sacrifice,

then maybe
you shouldn't be here.

And I think all of us
on some level, every day,

live that because it's important
to pay respect to their efforts.

And certainly in this endeavor,
that's what we try to do.

We're slowly working
towards the "X marks the spot."

So this could be
a very important clue.

-Yeah.
- And talk about
concrete evidence, eh?

-Mm-hmm.
-Here it is.

Every clue builds
on another clue,

which ultimately,
hopefully will get us

to where we want to go.

All right,
let's get the results.

First step, bring that to Emma.

- Yeah.
- See what she has to say.

All right,
I'll let you guys know.

And we'll keep working.

- Okay, let's get back to work.
-Yeah.

perseverance is perhaps
the most valuable asset

that will enable them to solve

the 229-year-old
Oak Island mystery.

While setbacks are
likely to continue,

they will leave
no stone unturned

in order to find new pathways
to the answers that they seek.

And with every new clue
that is unearthed,

a legendary treasure

may soon be within their reach.

Next time on
The Curse Of Oak Island...

-That's a beam.
- Yep.

And somebody stacked
those cobbles.

This might be a part
of the flood tunnel.

Wow.

If that is strapping,

it could be on a chest.

Yes, now that is interesting.

We're gonna insert this radar
to look for voids.

Okay.

127 feet from the surface

we get a void space.

This could be
the fabled offset chamber.
