Tonight, on The Lost Gold Of World War II"...

‐ Rain's definitely not ideal for this.

Racing against the clock, here.

‐ That could be the back door that we've been looking for.

‐ This is where I would drill.

‐ Fire this baby up!

‐ That's a box marker.

That's carved in there, man. It ain't no natural thing.

‐ Ho, ho, ho

‐ What the hell did this thing hit?

‐ So the Nazis were teaching the Japanese how to make concrete?

The only way bubbles could be coming out of there

is if there's a tunnel down there with air in it.

‐ That's no coincidence.

There's something going on at that level.

‐ For 70 years,

legends have been told of a buried treasure,

shrouded in danger.

It's one of the great mysteries of World War II.

‐ Something very secretive and strange

has gotta be buried in that mountain.

‐ In a covert operation,

infamous Japanese general Yamashita

allegedly buried thousands of crates

throughout the Philippines near the end of the war.

‐ They were just taking anything of value

gold, silver, weapons, even military secrets.

Yamashita's treasure could be anything.

‐ Now, with the help of a key eyewitness...

...a team of Americans is on the hunt

for this lost chapter in World War II history.

‐ Here's something, right here in this area.

‐ The question we have right now is

what is the best way to get inside this mountain?

Lost Gold of World War II Season 1 - EP 6 - Nazi Concrete

Subtitles Diego Moraes / Ewerton Henrique www.oakisland.tk

‐ The marker was right here.

‐ Oh, yeah.

Right here.

‐ Peter Struzzieri and his team

are attempting to find a back‐door entrance

into a network of tunnels

they hope leads to Yamashita's treasure.

They got here by following a trail of symbols

This stone pyramid pointed the way to a massive boulder,

apparently carved into the shape of a turtle.

‐ This is the best thing we've found so far.

‐ The turtle pointed the way to another symbol

a circle with a distinct set of lines inside.

Symbols expert Martin Flagg

theorized it could be a Golden Lily marker

for a back door.

‐ So the Imperial family would have needed

a different way to get into the treasure tunnel.

‐ Exactly.

They needed a back door to get in,

where not a lot of people could see them.

We need to look this area over real good.

We're gonna look for some rocks piled,

and if we can find that, that may be the way in.

‐ Now, the team searches the area near the marker,

looking for a formation of rock

that resembles the marker itself.

‐ Look at these rocks way up here.

That's a pretty sizable rock right there.

You guys wanna move back, I'll clear it off a bit.

‐ Lifted up off the ground a little bit over there.

‐ Thisto my eye, this looks stacked.

Know what I mean?

‐ Feel it right here,

how rough the edge is coming beneath here.

That's all natural.

Martin, you see this crack in the rock here?

You see how rough the edges are on this rock here?

So this is typical where the rocks have separated.

‐ Oh, yeah. ‐ Okay?

And they'rethey're rough, they're sharp.

This will not be it.

We're searching this area for any carved stones

or any unnatural rock formations

that may have been placed deliberately

to hide our back door.

So let's look for something that's out of the ordinary

a group of rocks where the edges have been worked

and are rounded.

Let's move on.

‐ Looking for very large rocks?

‐ Very large, very large.

‐ Hey, John, I think I found something!

‐ What is it? ‐ What do you got?

‐ Check this out. ‐ What the hell?

‐ So what do we do with this ‐ Holy [ bleep ], look at that.

‐ You know, looking at it,

it definitely has just a weird look to it

Like if it was just, you know, three rocks that broke apart,

they would have straight, crackly, edges.

‐ These look like they've been smoothed down and worked,

and this rock has been fitted in there.

You know, these three rocks, and the three triangles,

really kinda looks like the marker.

‐ Uh‐huh.

‐ And what do you see? You've got the three rocks

yep, here, here, and there

just like in the symbol we had over there.

That could be the back door that we been looking for

‐ If we move this rock here,

there'd be an entrance here, maybe?

‐ There could very well be an entrance here.

I believe this back‐door symbol

has led us to this formation of rocks.

Now we have to come up with a plan

to figure out how to get inside it.

‐ We need to figure this out, guys.

Let's go back to base camp.

‐ Let's say that this is our back door.

Keep looking at our main map

and where the location of the back door is,

you know, so it's, you know, roughly right here.

And our turtle, you know, which would've been, you know,

a classic front door entrance, sits over there.

We draw a line between the two, you know,

it could connect a tunnel

from the front door to the back door.

‐ And look what this line goes through

it goes through our pyramid

and the hole at breach six.

I wanna rip these rocks out and see

if there is a tunnel behind that formation.

‐ Look at this rock. It's like 50 tons.

Our excavator's only 25 tons.

I mean, how are we gonna move this?

We can't get down to the front side of it,

there's no way to get over the cliff.

This is tucked into the face wall there,

soand there's big piles of rocks up here.

Just getting the excavator up

over the top to even work it,

it's gonna be a really hard task.

‐ Well, y'all got more of a problem there than you think,

because it looks like if you move this rock,

this could collapse.

It could close your tunnel. Not only that,

you go to move these rocks in the wrong order,

you could set off any kind of traps they have inside,

which could be any any kind of explosive

they wanted to set up

and close the tunnel up permanently.

And the Golden Lily would've had a map or something

telling where and what kind of traps they have inside,

which we don't have. ‐ If what you're saying is true,

I don't want to move any of these rocks right now.

We better figure out a better way.

You have any ideas? ‐ I do.

I think we should do some testing there.

I think GPR would work here.

‐ GPR is a precision scanning method

that shoots high‐frequency radio pulses

into the ground to detect subsurface features

like tunnels and caves.

A common tool for engineering and construction projects,

it is also used by the military

to locate unexploded ordnance,

or by law enforcement to find unmarked graves.

‐ So if there is a tunnel there,

the GPR can look down in the ground

and can see any void spaces, tunnels.

Any anomalies that don't belong,

the GPR will pick up. ‐ Okay.

I like this plan.

We couldif there is a tunnel there,

we can set up the drill, drill down

Drop a camera down, and see what's there,

and verify that the tunnel does exist.

‐ I agree. I know a guy who can help us out.

‐ All right, let's make this happen.

‐ John reaches out to his colleague,

ground‐penetrating radar expert

Dr. Daniel Bigman.

‐ Hey. ‐ Good to see you.

‐ Dan Bigman is one of the world's leading authorities

on GPR technology,

and has extensive experience

scanning archaeological sites,

ranging from Roman ruins

to Native American burial grounds.

‐ We're glad to have you here.

‐ Yeah, thanks, glad to be here.

‐ To begin scanning for evidence of a possible tunnel,

the team leads Dan to the area

above the suspected back door rocks.

‐ So Dan, if there is a void or a tunnel down there,

what are we gonna see on the screen?

‐ We'll see like a bright spot, almost

a hit of some sort.

So a tunnel filled with air should be a big contrast,

and our hope is that we see it really nice and bright.

‐ Awesome. ‐ Sounds good.

‐ I'm looking forward to seeing something.

‐ All right, you want us to clear some rocks out of the way?

‐ Let's go ahead and clear the rocks out of the way

so we can get started collecting.

It's an interesting site.

It's definitely intriguing

I'm really curious to see if there's something going on.

All right, I'm gonna press record

and I'm gonna start going. ‐ Go, go.

‐ 'Cause we're racing against the clock here.

Rain's definitely not ideal for this.

‐ Watch that rock right there.

‐ We are seeing some responses, which is a

maybe gives us a little bit of hope.

Why don't we run another one back,

get a couple more examples, so let's

‐ Let's do that.

‐ Let's go in and analyze the data together.

‐ Dan only needs to collect a few more GPR readings

for a complete scan of the back door site,

but a fast‐moving tropical storm looms on the horizon.

‐ You know, a typhoon coming in,

it's not like it's just a little rainstorm,

might just pass by.

You know, we're gonna be in for some weather,

and just pray that we get a window

that we can actually use this thing.

And now, Mother Nature is saying,

"No boys, not today."

All I can do is just keep my fingers crossed.

Anything interesting?

‐ We're seeing very small responses.

‐ So, youyou're seeing an anomaly right there?

‐ Well, it's something that we kinda would expect

from a possible tunnel.

It's hard to make determinations in real time.

That's why it's better to collect it

go back, maybe process it, clean it up,

and then start to analyze it as a group.

‐ Let's fold this up and get back to base camp.

‐ All right, sounds good. ‐ All right.

‐ So wejust going over the data from today,

we actually did get a response, okay?

‐ Super. ‐ Yeah, that's great news.

‐ Soso we got this hit at about 40 feet, okay?

So over here, what you have is this arch,

which we would expect from a tunnel

or a void of some sort.

‐ These lines are telling you that this might

be a void or a tunnel.

‐ It might be. ‐ Might be.

‐ The only way to verify what this response is

is to take a drill and peek in.

So we ended up doing a large grid area,

and we got this hit right here.

‐ Awesome.

‐ So this is where I would drill.

‐ As a major storm gathers,

a GPR scan has revealed

what could be a void or even a tunnel.

The plan is to drill down 40 feet

in an attempt to access it.

‐ I agree with you.

That's a good place to start drilling.

Great job. Thank you so much.

‐ No problem. ‐ Yeah.

‐ Yeah, that's awesome. Perfect.

‐ We gotta get you outta here before the storm gets any worse.

‐ Yeah, absolutely, before the storm gets in.

‐ All right, let's go.

‐ The next day, Typhoon Mangkhut,

a category‐5 super typhoon,

strikes the Philippines.

‐ The second‐biggest typhoon ever recorded

is hitting us today.

Can't get any work done.

Very risky, to even get out there

and walk around.

You could get hit with a tree limb,

could be washed right down the river.

Mudslides are getting bad

just wipe us right off the hill.

It's not a good thing at all.

You know, I'm worried about my team,

my crew, everybody here.

This isn't even the worst of the storm yet.

Forecast is that this storm will last all day,

possibly into tomorrow.

We're gonna wait it out, we'll hunker down.

And with the GPR possibly revealing a void,

we're so close to finding our way into this mountain.

Hopefully this will pass soon and we can get back at it.

‐ After 24 hours of intense rain and wind,

the storm passes.

The team reconvenes at base camp,

eager to get back to work.

‐ I checked on all the equipment,

I checked on Grandpa,

everything is okay.

‐ If that storm was any indication of, you know,

what's in store for us in the future here,

with all this monsoon season,

we gotta get moving.

We're losing time pretty fast here.

‐ You think that the typhoon has impacted our search?

‐ The Japanese engineers were pretty smart.

You know, they were planning

to come back and get this treasure,

you know, maybe ten years, a hundred years,

a thousand years from now.

So any place they would've put markers

would've been etched into stone

that wasn't gonna go anywhere.

The storm may have uncovered something

that we didn't see before.

I'm gonna take Manny out

and maybe we can find something that we never found yet.

Let me grab him and we'll get it done.

‐ I'll get the drill ready, you go do some more searching.

‐ All right, cool. Sounds good.

‐ John and Manny head out with a metal detector

to see if the typhoon cleared away foliage,

revealing any new clues.

‐ Just keep your eyes open, Manny.

That's what I'm hoping for, some easy pickings today.

Hey, you never know, you might get lucky.

‐ Oh, there's a freshly downed tree right there.

Maybe the wind took it over.

That windstorm that we had

just ripped it right out by the roots.

Oh, yeah.

Still‐fresh fallen trees like this,

if, you know, we leave them sitting here

rotting away like that,

if there was any markers on there,

they're gone forever.

Maybe just do a quick scan around it.

‐ You see any signs or symbols?

‐ I don't.

‐ There's more trees up there.

‐ Yeah, let's give it a shot.

‐ Meanwhile, at the back door site,

guided by the GPR data,

Peter marks the exact spot

where they believe the void may be,

40 feet below.

‐ In between these flags right here,

there is an anomaly

we think a void.

‐ Finally we get to do something

we know what to do.

Here we go!

‐ Heavy equipment operators Brad and Jeremy

have located a drill

capable of cutting through bedrock,

and maneuver it into position.

The GPR results show a possible void space

40 feet below,

but getting that deep with this older machine

won't be easy.

‐ This is what we came for.

Came halfway around the world to find a tunnel,

and that's what me and Brad are gonna do

find a tunnel.

Easy, easy!

Right on the money, baby.

‐ Right on the mark.

‐ Good deal.

‐ That's how it's done.

Man, this is we're there.

‐ Yeah. ‐ We're there. The first step.

‐ With the drill in position,

Peter joins Brad and Jeremy at the back door site.

‐ Hey, guys. ‐ Hey.

‐ Couldn't you find something older than this?

‐ Yeah, it's okay.

‐ This thing is older than me.

‐ We're gonna work with what we got.

‐ Now that the drill is on the mark,

the team assembles the rigging to lock it into place.

‐ Oh, nice job, we're getting ready to drill.

This is getting exciting now.

With this drill, we're gonna prove

that there's something down 40 feet in that ground.

We did see some anomalies on the ground‐penetrating radar

that show that there could be a tunnel or a void there,

and this drill is gonna take us to that spot.

You all set? ‐ We're ready.

‐ You're all set? Fire this baby up!

‐ Here we go, fire it up.

‐ Like many older models,

this gas‐powered drill requires constant water cooling

and careful operation.

If the drill overheats,

it could permanently fuse

with the rock inside the shaft.

‐ Let's put it in the ground.

‐ At the back door site,

the team continues to drill down

to the desired 40‐foot depth

in order to verify the existence

of a potential tunnel that may run

all the way from the turtle rock

under Breach 6 and end at this location.

‐ There you go.

‐ The metal drill stems that connect to the bit

are only 10 feet long,

so the team attaches another length of pipe

in order to continue down to a potential void,

which they hope contains whatever Yamashita hid here.

‐ With their new stem attached,

the team is now capable of drilling 20 feet

halfway to their 40‐foot goal.

Meanwhile, John and Manny investigate

the recently thinned‐out jungle

to see if the typhoon revealed any new clues.

‐ Yeah, it looks like an old tree, huh?

‐ Yeah.

‐ That's a mango tree.

‐ Wish it had some mangos on it.

‐ Why this tree, John?

‐ Well, look at the size of this thing.

It's gotta be over 100 years old.

It was here with the Japanese here,

it was long it was here probably 30 years

before they even showed up.

So it makes just, you know, perfect sense

to check trees like this.

You know, just keep an eye out, look around.

I'll tell you, you're looking out for anything

that's kinda out of place on this tree

any markings, any scratch marks,

cut marks that are healed over.

Anything that looks like,

you know, it's a marker of some sort.

‐ According to the team's Golden Lily research,

Yamashita's engineers often carved markers

and symbols into trees,

usually acacia and mango,

due to their longevity and robust trunks.

It is alleged former Philippine president Marcos' wealth

was based in part on his recovering a piece

of Yamashita's treasure,

and it is rumored he ordered many trees with symbols

cut down in order to hide them

from other prospective hunters.

‐ Nothing on this side that I see.

‐ Yeah, let me get a scan on the metal detector.

‐ What you got? ‐ You hear that, Manny?

This hit is directly in line

with that piece of metal.

‐ You see anything there?

‐ I do, I see an old piece of wire

sticking out of the tree, grown right into it.

It looks like it was a piece of barbed wire.

And why would there be a piece of barbed wire here?

There's no other trees to attach it to.

That's pretty curious, actually.

When the Japanese were here,

I mean, they could've put this wire in,

it could've been a defensive position,

so they were putting wire down low.

In case anybody came up, they'd get snagged on it.

But it certainly wasn't put there yesterday.

You know, it's been there for quite some time.

All right, Manny, well, more trees, my friend.

Let's go.

We should check out this tree over here that's down.

It's still got green leaves on it.

Must've blown over in the storm.

Ohoh, crap, check that out.

Look at thislook at that.

That hasthat's been in there for a while.

That's carved in there, man.

That ain't no natural thing.

‐ Yep. ‐ That's a box marker.

‐ In the Golden Lily code,

a box marker is believed

to indicate a deposit of treasure.

The discovery of this box marker

could mean treasure is located

near this fallen tree.

‐ Let me get the detector fired up

and we'll check everywhere around here.

‐ Yep.

‐ I'm not getting any hits.

Get your knife, too,

so we can start picking away at this rotten root.

Just keep digging around here.

I hope it's something and not junk.

Man, this tree is like a perfect candidate.

I mean, you couldn't ask for a better marker.

You'd think for sure there'd be something there.

Manny, if there was

if there was anything around this tree,

we would have heard it

‐ Pretty disappointing that there's no treasure

under that tree.

Couldn't ask for a better marker,

we know the Japanese were here,

and there's no treasure under it,

and that's the way it goes.

Sometimes you win, sometimes you lose.

Defeat is part of the game.

‐ At the back door site,

Peter, Brad, and Jeremy are making good progress

drilling down to their 40‐foot goal

in the hope of reaching a potential void space,

and possibly a tunnel inside the mountain.

‐ All in all, it's going pretty smooth.

This old thing's doing a lot better than I thought it would.

We haven't hit a tunnel yet.

We gotta keep on trying, though.

‐ Ho, ho, ho.

‐ The drill is free‐spinning,

which could mean they have hit a dense layer

the diamond‐tipped bit can't penetrate.

So we're at 35 feet about now,

but we're not getting anywhere.

It's not cutting into that rock whatsoever.

It'd be foolish to keep on doing what we're doing.

‐ So we're at 35 feet about now,

but we're not getting anywhere.

It's not cutting into that rock whatsoever.

It'd be foolish to keep on doing what we're doing.

‐ At the back door site,

the team is only five feet away

from reaching their 40‐foot depth,

but they've hit a hard layer of material,

bringing drilling to a standstill.

‐ What happened, Pete?

‐ John joins the team to see what's holding up progress.

‐ We're not getting anywhere.

It's not cutting into the rock whatsoever.

‐ How deep are you now?

‐ We're about 35 feet.

‐ Oh, so you're right on that first anomaly zone.

‐ Oh, it'swe're so close to the anomaly zone, yeah.

‐ I guess you're gonna have to see

what it looks like down there.

‐ So we're gonna pull it out.

‐ Should we pull the pipe?

‐ All right.

‐ To get a look at the dense layer

that has brought drilling to a halt,

the team pulls the drill stems from the hole

to examine a core sample.

‐ What the hell did this thing hit?

Check that out.

‐ Whoait had to hit something awful hard.

Look how it's flattened out now. ‐ It's ruined.

‐ Flattened and rounded.

‐ The bit's no good any more.

‐ It's actually chipped over here, too.

‐ Damn, we hit something so hard

that it's destroying the bit.

‐ It appears a dense layer of material 35 feet down

has ground the teeth of the diamond‐tipped drill bit

to nubs.

‐ It's so close to the 40‐foot mark.

‐ Let me see the core if you can.

I'd like to see what's what you actually hit.

‐ It's full.

This stuff is really really hard stuff.

Harder than we've ever seen in our drilling days.

‐ Does it look like concrete to you?

‐ It could be concrete, it's hard to say.

‐ All right, guys, we're at a standstill

until we can figure out what's stopping us.

‐ We have a dilemma now.

We've hit something really, really hard.

It could be bedrock, but bedrock has never

chewed up my drills like this is.

I've worked with cement for 50 years

in construction on different sites,

but I've never seen this this quality.

It's so strong, so hard.

‐ How do we know this is really concrete?

‐ We don't really know, but I'm assuming

because it was so hard to drill through,

that it could possibly be bunker‐grade concrete.

And if it is bunker‐grade concrete,

then we're on the right track.

‐ What do you mean?

‐ We know that Yamashita was invited to Germany

and he met Hitler.

‐ In December 1940,

General Yamashita was sent to Berlin

on a six‐month mission to meet Adolf Hitler

and officers of the German High Command.

‐ During this visit,

Yamashita is known to have inspected

the hardened bunkers along the French coast,

and it is alleged he may have obtained

the Nazis' secret concrete formula

directly from Hitler's top engineers.

‐ So Yamashita knew Hitler. ‐ Yeah.

Hitler gave him the secret to bunker‐grade concrete.

‐ Nazi concrete? ‐ Yeah.

‐ The Nazis were teaching the Japanese how to make concrete?

‐ I think so. ‐ Wow.

‐ They had some, you know,

stuff that bombs couldn't get through.

And they shared that with the Japanese,

and the Japanese said, hey,

you know, this is great stuff.

We can use that to hide and protect all our treasures,

and no one will be able to get through it.

A bomb won't even get through it.

‐ During World War II,

while the Allied Forces were strengthening

their air and sea defenses,

Germany focused on land‐based fortifications,

constructing bunkers

made of a special reinforced concrete.

One such stronghold was the Wolf's Lair,

Adolf Hitler's top‐secret headquarters

on the Eastern Front.

Even after deliberate demolition efforts

by the American forces after the war,

the main complex still stands today.

In the Pacific, the Japanese forces

were also constructing similar bunkers and tunnel systems.

It is possible they may have used

the Nazis' secret concrete formula

when building their infamous tunnel defenses

for the battles of Iwo Jima and Okinawa.

‐ So now what?

‐ All right, guys, we're gonna send this off to Bingo

and have this tested to see if it is hardened concrete,

or what it's made out of.

‐ Days later, back in the United States,

head researcher Bingo Minerva

visits a geologist and concrete expert

to examine the core sample unearthed by the team

in order to determine

exactly what they're trying to drill through.

‐ Hey, Gerard. ‐ Hey, Bingo.

‐ Hey. Good to finally meet you.

I brought some samples with me,

and I wanted to see if you can at least

help us verify what we're dealing with.

You know, the guys,

they're at a total standstill,

they're breaking through bits

and these are the two samples that they sent me.

Just by looking at these, I was wondering what

you can tell me about them, if anything.

‐ Hm...

it looks potentially like bedrock of some kind.

It's very gray rock. Okay.

This one's kinda interesting here.

This one's got some smaller material,

almost looks like sand particles in here.

And there's kind of a gray cast to it.

Interesting.

Let me take a look at something else here.

‐ After studying the sample from Bingo,

Gerard believes he has an example of concrete

that matches it.

‐ So take a look at this.

This is shotcrete,

which is typically used to build pools,

to line tunnels, things like that.

And this shotcrete is made of Portland cement and sand.

Now it's kind of gray. This is definitely gray.

And notice how there's no coarse aggregate in this.

‐ Yeah, no big pieces in either of them, very similar.

‐ In either of them.

And lookwe have some sand‐sized particles in here.

Got a lot of sand in this shotcrete.

There's a similarity there that we're gonna want to look at.

And so we're gonna have to spend some time on this.

‐ Well, I can't wait to hear some results.

‐ The next day, the team gets the results

from concrete specialist Gerard Moulzolf.

‐ Hey, Gerard. ‐ Hey, guys.

‐ We hear you have some information

on the concrete samples we sent you.

‐ Yes, this is the one core sample that we received.

And while this while this core here

looks like it's got sand in it,

which looks like it's Portland cement

‐ Mm‐hmm.

it's actually not concrete.

‐ Oh. ‐ Hm.

‐ In base camp, the team is receiving

the final report on the core samples

from geologist and concrete expert Gerard Moulzolf.

‐ It is actually an extruded lava flow.

In the Philippines,

that whole core of the island

is made of volcanic material,

a great majority of the island.

‐ Well, if we do come across a concrete‐like substance,

is there a way to tell the difference in the field?

‐ Now this is a concrete that was made in Guam,

and this is essentially a coral.

And the mixtures that would've been produced

by the armed forces from Japan

that maybe are doing something very quickly,

they probably would've hand‐mixed it with a shovel.

‐ With a US blockade surrounding the Philippines

and resources dwindling,

it is believed the Japanese engineers

may have used any possible materials available

as aggregate in their concrete,

including crushed coral and seashells.

‐ You're gonna see chunks of shells, chunks of coral,

you know, chunks of reef rock,

if they were using that type of aggregate.

‐ Gerard, thank you so much for your time.

‐ Thanks.

‐ Well, that was very interesting, guys.

‐ That was interesting.

‐ But that was not the information

I really wanted to hear.

We're gonna have to find another way

to get into this back door.

‐ Well, I still believe

that this is our way into the mountain.

Suppose the drill

cause it's only drilling a five‐inch hole

suppose it's just hitting a small section of hard rock.

We do have the ground‐ penetrating radar that says

that there is a void there at 40 feet.

We're down 35 feet.

We have five feet to go.

Let's stay there and do this until we find out

for sure is there a tunnel there

or there isn't a tunnel there.

‐ That's a lot of time drilling.

We don't know how long it's gonna take.

‐ Well, we'll pull up the stems and I'll change the bit.

‐ But we could burn up the drill.

‐ Well, that's athat's a risk I'm willing to take.

If we burn up the drill, we burn up the drill.

I have to stay and find out if there is a tunnel there.

We're five feet away from the void

that the ground‐penetrating radar

showed us was definitely there.

I can't leave now.

This is our best way in.

Let's go, guys.

Let's get back to drilling.

‐ I don't care if we go through 50 bits,

I'm gonna get down to that 40 feet

one way or the other.

‐ At the back door site,

the team is only five feet away

from reaching their 40‐foot depth,

but they've hit a hard layer of material,

bringing drilling to a standstill.

Adding a fresh bit,

they resume their efforts to punch down

into a potential void below,

which they believe could be a tunnel

intended for members of the Golden Lily

to recover their treasure after the war.

‐ I hope we get all the way to the bottom today,

go right into the tunnel.

‐ Ready to fire it up? ‐ Go ahead.

‐ I don't care how fast you go,

as long as it keeps going down.

‐ Brad increases the drill speed to its maximum

in order to bore through the layer of hard volcanic rock.

‐ To determine if they've cleared the hard layer of rock,

Peter checks the slurry that comes out of the hole.

‐ Look what I found

a little piece of a seashell.

According to our concrete expert,

the Japanese, when they ran out of sand,

they mixed some type of coral in their cement.

This seashell could be part of that process.

I mean, it's a wild theory,

but we're not gonna discount anything.

‐ Earlier, we got down to 35 feet,

and then we hit something really hard.

We're about five feet

from where the radar picked up an anomaly.

‐ It's something that we kinda would expect

from a possible tunnel.

‐ Okay. All right.

‐ That anomaly, we're hoping, is the ceiling of a tunnel.

Now we find bits of seashells in our cuttings.

‐ Pieces of seashell in the slurry

may be evidence of Japanese concrete

from a Golden Lily treasure tunnel.

‐ But we're getting close.

‐ Up on the mountain, the team has been attempting

to drill down to a depth of 40 feet

to verify the existence of a potential void space

behind what they believe

is a back door entrance into a tunnel

may run from the back door site

directly to the turtle rock.

‐ Right here it's chugging along!

‐ The water inside the hole suddenly starts to drain.

‐ This is an indication the drill

may have punctured the roof of a possible tunnel.

‐ How deep are we?

‐ Just past 40 feet. ‐ Just past 40 feet.

‐ Yep. ‐ So that's no coincidence.

There's something going on at that level.

‐ The only way bubbles could be coming out of there

is if there's a tunnel down there with air in it.

‐ So what do we do next?

‐ Next thing is that we're gonna drop the camera

down there and see what we got.

‐ Sound like a great plan to me.

‐ That's what we've been looking

‐ That's what we're here for.

‐ That's what we're going for.

‐ Took us a while to get here,

but we're at that point for taking pictures.

‐ Well, let's get to it. ‐ Okay, guys.

‐ To verify what's underground,

John brings the probe camera to the drill site.

‐ How's it looking, boys?

What, did you lose water?

‐ A lot of water, lot of water.

Let's get that camera down there.

‐ All right.

With the water disappearing down this hole,

I'm pretty sure we're on that void space.

I wanna get a camera down that hole

and see if we're on this void.

All right, let me do this.

We're in the dry section of the hole.

All right, you're coming down,

nice and easy.

‐ What's the measurement?

‐ Twelve feet...

Seventeen feet.

‐ Go ahead.

You're in the hole, keep going.

You're smacking up against the side, hold on.

‐ Twenty feet.

‐ You're in the sidewall again, come back to center.

‐ Twenty‐six feet.

‐ Keep going, go ahead

‐ Thirty‐three feet.

‐ You're good, you're centered.

‐ Thirty‐five.

Looks like we're gonna go swimming here shortly.

‐ Yep.

I see the water coming up.

‐ Let's take the plunge.

‐ We're right at 40.

‐ Hold it there. Don't go down any further,

because I can't see the side wall

of the pipe any longer.

Give me a slow twist in a 360.

I'm not seeing any side walls whatsoever, Pete.

‐ Let me take a look at that.

Justlike, I have to see for myself.

This is really important.

‐ Take my seat.

Now twist slowly, Brad,

so you don't muck the water any more.

You just see water.

‐ Oh, yeah.

I don't see anything.

‐ I think it's a void.

It looks like you're actually in a void space now.

‐ On the next "The Lost Gold of World War II"...

‐ There we go.

‐ Here we go.

‐ I had no idea that my brother was connected with the CIA.

‐ Do you have any documents

or any other proof of CIA involvement?

‐ Yep, come with me. Let me show you some things.

‐ Come on over the cliff edge here.

‐ All right, coming.

‐ You're not gonna believe this.
