All language subtitles for Lost Gold of World War S02 E05_track3_[eng]

‐ Narrator: ..."Lost Gold
of World War II"...

‐ Holy [ bleep ].

We got a major cave‐in.

If we can't get
around this collapse,

then we'll never get
inside the mountain

to get this treasure.

‐ "X" marks the spot.

‐ Knowing that there is
a void space

deep down
underneath the waterfall,

and knowing
satellite has confirmed

a big metal target there,

this drill's our best bet
to get there.

‐ I got some incredible news
for you.

I just found Chuck McDougald.

He has about 20 Yamashita
treasure maps.

‐ Keep it coming.

‐ Narrator:
John Casey and Rick Hurt

are back in the Philippines

with a new team,

continuing their search
for Yamashita's gold.

‐ We're gonna find a way
to get to this treasure.

‐ Like many others,
John believes

Japanese general
Tomoyuki Yamashita

took billions of dollars
in treasure

looted by Japan
during World War II,

and buried it
in the Philippines,

including somewhere
in this mountain.

Following a series
of mysterious symbols

they believe were left
by Yamashita,

the team is investigating
three sites‐‐

a waterfall...

‐ John: This waterfall
is hiding something.

‐ ...a crater
known as Breach 6...

‐ I've never seen
anything like this.

‐ ...and a camouflaged tunnel
they uncovered last year.

‐ We are in the mountain,
boys!

‐ Can they finally
discover the...

Inside the tunnel,

miners Levi and Geo are
clearing a massive collapse.

‐ This is a mess.

This thing's caved in
as far as I can see.

I'll tell you, you run
into something like this,

it's never easy
to get through it.

I mean, we're looking
at a month,

maybe two months of work
to get around this thing.

‐ Based on recent discoveries
of animal bones

and a World War II‐era
Japanese landmine,

the team wants
to continue exploration.

‐ Boy, that's some
very unstable ground.

‐ But this dangerous mess

is stopping them dead
in their tracks.

‐ Let's do it.
[ creaking ]

Do you hear the ground
taking weight?

Listen.

[ creaking ]

I mean, you can see
right there.

‐ Yeah.

‐ That there‐‐
that's the danger zone, man.

‐ Yeah.

‐ I've dealt with collapses
like this in the past,

and messing with these things,
a lot of times

you're opening
a giant can of worms.

We don't know
the extent of it.

We don't know how far it goes.

We can't see the top of it.

[ creaking ]
It's the unknown.

‐ Their only option is
to tunnel around the collapse.

But digging through hard rock
presents a major challenge.

‐ Hear this?

[ clank clank ]

That's real rock.

‐ Yeah.
‐ Over here...

[ thump thump ]

it's bush.

We want to be
into this hard rock.

We don't want to be
into this bushy, nasty stuff.

[ clatter ]

[ creaking ]

It's nearly impossible
to go through this by hand.

It's gonna take
way too much time.

With all this hard work
we've put in,

all the obstacles
we've overcome‐‐

there's been
so many different clues

inside this tunnel‐‐

there's a really good chance

that there's treasure
at the end of it.

Now we got to make
a plan of attack

to go back in there
and get around this collapse.

‐ Farther down the mountain
at Breach 6,

miners Brent and Farrell
continue their excavation,

inching closer
to the line of metal deposits

detected by a recent scan.

15 feet deep,

they've already unearthed
a solid slab

of manmade concrete

and a 4‐inch‐thick layer
of charcoal,

both of which
Robert Curtis also found

at his treasure sites
nearly 30 years ago.

‐ According to Robert Curtis,

the Japanese were
leaving layers

as an indicator
to find treasure.

‐ Rick also
recently discovered

part of a buried
Japanese World War II

military rifle here.

‐ You have a Type 99
Japanese Arisaka rifle.

‐ All signs suggesting

they could be
on the right track.

‐ Brent:
All the things we've found,

it's like driving me forward

to want to get down
to the bottom.

It's encouraging me,

and it's showing me
that it's, like,

we're actually
on to something here.

I'm not sure
what I have here.

Kind of red like clay but...

It's rock‐hard.

Hey, Johnny!
‐ Yeah.

‐ Dude, come on down here
for a minute.

‐ Okay.

‐ Not sure what it is, Johnny,

but it's all over
down here, dude.

It's really, really hard,

and I can break it
with my pipe wrench.

Kind of a stone, but...

‐ Kind of looks like slate
or granite.

It's got to be.

‐ It's like
a granite countertop.

You're right.
That's what it looks like.

‐ I mean, there's three
flat sides on that one.

‐ I'm gonna dig
a little bit more, dude.

I'll see how much more
I can find here.

The stone we just uncovered

kind of looks like a, uh,
granite of some kind.

It's got machined edges
here and there.

It's broken up.

It's just been
straight through.

Like‐‐And it's like
a consistent layer

all the way through.

‐ I say we stuff our pockets
full of this stuff,

head back to basecamp
and show the boys.

‐ Over at the bore hole
site...

Rob and drill operator Andrew
make slow but steady progress

across the mountain.

‐ We're in about 100 feet.

We've got a ways.

We're looking at a little
over 900 feet to our target,

so we're a little over
a tenth of the way there.

‐ The horizontal drill
is their last option

to reach metal deposits

identified
below the waterfall.

‐ Knowing where the treasure is
is one thing.

Getting to the treasure
is something else.

‐ Since environmental
restrictions

prevent them from digging
at the waterfall...

they're drilling horizontally

930 feet through the mountain

towards the void space...

so they can feed in
a bore hole camera.

‐ There's lots
of bore hole cameras

that will make it 930 feet

to see exactly what we've hit.

‐ For the 3‐inch drill
to hit the void space

from 930 feet away,

it must maintain
pinpoint accuracy.

‐ I'm getting
more and more anxious

because as we move further in,

our ability
to make a correction

starts to shrink down
by a lot.

‐ If the drill is
knocked off course

by even a fraction
of a degree,

it could miss the void
entirely

by the time it reaches
target depth.

They need to constantly
monitor core soil samples

taken by the drill

to ensure the bore
hasn't shifted.

If the samples stay the same,

they know they are on
the right directional track

for the void.

‐ We're about to pull

about another 4 1/2 feet
of the core sample.

I'm just keeping
my fingers crossed

that it's that exact
consistent type of rock

that we know is gonna keep us
on a straight path.

‐ What are we looking at,
Andrew?

Yeah, it's like decomposed.

‐ So now that I see this,
it's a little bit concerning.

‐ But things like this might
be a little bit of an issue.

‐ They also need to monitor
any changes

that could jeopardize
the expensive machinery.

‐ Just got to keep an eye
on this.

Rob's certainly been
under a lot of pressure here,

you know. This is a longshot
by far, you know.

When you got to drill
900 feet

with a little 3‐inch drill

to a little spot
maybe 20 by 20,

you know,
underneath the waterfall,

it's a‐‐
it's a hell of a task.

I mean,
we're not that far in yet.

We're only about 100 feet,

but, with 800 feet to go,
anything could happen.

[ helicopter overhead ]

Seeing that, Rob?

Helicopter coming in.

Rick, you seeing
that helicopter?

We just got buzzed.

‐ It's a little disconcerting.

I was trying to get my, uh,
phone camera on it

to zoom in and see
if I could get numbers,

but I, uh...

‐ Copy.

Yeah, I see it right there.

‐ There's two of them.

There's another one behind it.

It's the first time

they've spotted
aerial surveillance

in the two years
they've worked there.

‐ We've been warned about
being watched by somebody.

[ voice distorted ]

‐ The team's new partner,

experienced treasure hunter
Chuck McDougald,

also warned them.

‐ There are people

that are gonna observe
everything you do,

and if and when they think
you've found a treasure,

they might step in

and, uh, either steal it
from you

or just kill you
right then and there.

‐ Rick: I'm just wondering
if they just came in

for a quick check
on our progress.

‐ Copy that.

All right.
Just keep an eye open,

and, uh, you know,
it's just‐‐

it's just another damn thing
to worry about.

If you're going after
a treasure like this,

chances are
somebody's watching.

‐ At the tunnel,

father and son miners
Geo and Levi

bring in a remote controlled
demolition robot

to help dig
around the collapse.

‐ Hopefully this thing here
will be our saving grace

and it'll make stuff
go a lot faster.

It's like a mama excavator
packing its little baby,

packing it back to its nest.

‐ This is it, huh?
‐ That's it.

‐ You know, it's the same
color as a lemon, right?

‐ 'Cause I was gonna say

you want to keep shoveling?
I can take it back.

‐ But I got to see it
to believe it.

I don't know.
‐ Well, you can go in there

and pickax it.
‐ It's a little small, though,

though, isn't it?

‐ Hey, man, dynamite comes
in small packages.

‐ Okay.

‐ Remote controlled
demolition robots

are often used
in the mining industry,

where it is unsafe
or inefficient

to work by hand.

They're equipped
with multiple attachments,

ranging from cutters
to claws,

but their primary tool

is a hydraulic hammer‐chisel

that can strike
with up to 2,320 pounds

per square inch of pressure.

At a rate of 608 strikes
per minute,

this machine gets
the job done

in a fraction of the time
it would take

to shovel out the debris
by hand.

‐ The only way that we're gonna
know what's inside the tunnel

is to get past the big,
massive cave‐in

and‐‐and find out
where this thing goes.

‐ I'm gonna drop
the down riggers now.

Moment of truth.
Are you ready?

‐ I'm way ready. Let's see
what this thing can do.

‐ Levi: Chews it up, man.

‐ Definitely breaking rock.

‐ We got a goal, and that goal
is to get the gold.

We're not taking no
for an answer.

‐ At basecamp,

Rick and John get an update
from Bingo.

‐ Bingo.

‐ Morning, guys.
How you all doing?

‐ John: We're doing good.

‐ Narrator: While searching

for Yamashita treasure maps,

Bingo was introduced

to an associate
of the late Robert Curtis.

‐ Brian Greenspun:
Chuck McDougald.

He's one of those experts

on this whole
Yamashita gold story.

‐ While meeting
with McDougald,

Bingo got his hands
on treasure maps

Chuck obtained
from the office

of former Philippine president
Ferdinand Marcos.

‐ These are incredible.

I've never seen
anything like this.

‐ Yeah.
‐ In any of my research.

We're literally holding
pieces of history right here

if he did in fact
recover this treasure.

‐ After negotiating a deal...

‐ I think,
if treasure is found,

I would share in that.

‐ If that's what it takes,
then let's do it.

‐ ...McDougald agreed
to share the maps,

hoping one of them
could be their mountain.

‐ Bingo: I got some great news
for you guys.

Check it out.

A Golden Lily treasure map.

‐ Really?
‐ Unbelievable, man.

‐ Is it the real deal?
That's great.

‐ I think
this one in particular

looks a lot
like our mountain.

‐ What makes you think
it's a map of our mountain?

‐ There‐‐There's a number
of features on here

that made me‐‐
that made me think

it looked like our mountain
in particular.

I mean, there's some
mountaintops here.

There's a waterway
that goes through it,

and there's this‐‐this area
in the middle here

that I believe
looks like Breach 6.

It's almost like a schematic
of what it would look like.

‐ Bingo, I'm starting to see
what you're seeing.

You can kind of see,
uh, something

that looks like it could be
the Pyramid Rock.

I think
you're on to something here.

‐ I'm glad
you guys are seeing

the same thing I was seeing.

‐ I wonder what all that
other stuff means.

I mean, I can't really see
a scale on this,

so we got some work to do.

We're gonna have to try
to figure out

all the rest of these things.

‐ Thanks again, Bingo.

‐ All right, guys.
I'll talk to you soon.

‐ Narrator: John and Rick
take a closer look

at the map.

‐ There is so much stuff
on this map, man.

‐ Yeah. There's a huge amount
of information on here.

Look at this thing.
I mean, I would like to know

what the rest
of this stuff means,

but the river, really‐‐
‐ Mm‐hmm.

‐ ...it matches our river
in the bends and everything.

‐ Right. I'm super interested
in finding out

anything about this area
and these shafts.

‐ Yeah. I know. This whole
box thing in the center.

I think that's, you know,
pretty important.

It's, like,
one of the main features‐‐

all these arrows
pointing to it.

It's got to have
some significance.

‐ There's a couple of things
on the map

that really make me believe
it's a map of our mountain,

but there's so much stuff
on this map

that we don't understand
at this point.

‐ What's all this,
like, grass up here?

I mean, is it, like,
bamboo or something?

‐ I don't know, man.

‐ What do you suppose
this clock's all about up here?

‐ Based on my prior knowledge
of treasure hunting

and other people
I've worked with,

they've told me
that this clock face

represents directions,
markers,

and the amount of paces
you would need to go

to get to that marker.

You know, there's a lot
of stuff here,

like all these holes here,
whatever this is.

I don't know if this is
a cross section of that

or this is
a cross section of this.

It's great to have a map,

but there's no scale
on this map.

There's no references.

Whether it's our mountain
or not,

I just don't know.

So if we want to get to use
the map to our advantage,

we're gonna need to figure out

whether this map
actually is our mountain.

‐ After discovering
an unusual rock layer

in Breach 6,

the team sent geologist
Gerard Moulzolf

a piece for analysis.

‐ We sent you that sample.

Were you able to find
any information about it?

‐ Yeah, absolutely.

We went through a number
of simple geologic tests

to help determine

what minerals
and what rock this is.

First thing we did is

we put a little dilute
hydrochloric acid,

and it fizzed wildly.

We also utilized the latest
technology‐‐

L‐I‐B‐S, or LIBS.

What it does is it actually
fires laser beams

down onto the stone,
surface of the stone,

and produces a plasma.

And it reads the plasma

and determines
what the elements are

and what their relative
percentage is.

So we came up with calcium,
carbon, and oxygen

and then quite a bit of iron,
which is certainly the reason

why this material is so red,
confirming a marble.

‐ Red marble?
‐ Red marble, yeah.

I mean, that's
the weirdest thing ever,

to find marble
in a place like this,

all broke up.

‐ Narrator: While searching
for Yamashita's treasure

in the Philippines,

Robert Curtis found marble.

As did Chuck McDougald.

‐ During the, uh, dig
at Fort Santiago,

at the 40 meter level,
we encountered marble

and gold flecks on our drill‐‐
on our drill bit.

It was already in the maps

that they built
the marble fortifications

before bringing in
the treasure.

‐ That's amazing.

‐ So, John, what's really
interesting about this

is it is not native
to the Philippines.

‐ That's incredible.

‐ This nodular texture

that we see here,

it is almost as unique
as a fingerprint.

We've got some white
calcite vein here.

This is all highly special.

‐ Mm.

‐ So I actually tracked down
the exact quarry

that this came from.

This is actually
French marble.

‐ Wow. I wasn't expecting you
to say that.

‐ France.

‐ And what's so unique
about this

is this particular quarry
has been known

to have been mined
since the first century BC

by the Romans.

‐ Holy smokes.

‐ And King Louis XIV
used this quite regularly

in the palace at Versailles.

So this is
a very famous marble.

This was the king's quarry.

‐ Narrator: This red marble
famous originates

in a quarry
in southern France.

It's possible
Japanese forces looted it

when they conquered
French colonies in Asia

during World War II.

But it's also possible

that the marble was seized
by Germany

when it occupied France

and then given by the Nazis
to their Japanese allies,

including General Yamashita.

In 1940, he spent
six months in Germany

on a secret
intelligence mission,

even meeting
with Adolf Hitler.

The marble's presence here

could suggest
one shocking possibility‐‐

a treasure so vast

that the Nazis and Yamashita
were cooperating.

‐ How in the world
did it ever get

to the bottom of a hole
in the Philippines?

‐ We know this is special.

We know this came
a long way to get there.

We can only speculate
how it got there.

‐ Thank you again.

We do appreciate
everything you've done for us.

‐ Any time.
‐ We'll talk to you soon.

Yeah, what's significant

about this marble discovery
at Breach 6

is that...certainly not
a natural occurrence,

so somebody put
this red marble in that hole

for a reason,

and what is the reason?

Does it indicate
that we're getting closer?

Does it indicate

that we are on top
of a treasure?

The only way
we're gonna find out

is to keep going deeper
inside that mountain

and see what it is.

‐ Intrigued
by the red marble discovery,

John heads over to Breach 6.

‐ Brent and Farrell are digging
through multiple layers

as they're going down
through Breach 6.

I want to know
how did all these layers

end up in our hole.

‐ We've been finding
all kinds of random things,

and then we come across
this red rock.

It's like a marble.

We're back into, like,

it's like a hard clay
type of layer.

It's not really wanting
to come out real quick.

An 8x8 hole is a big hole
to hand dig.

It's just huge,
and it's just wearing on us.

Hopefully we can hit
something exciting here

pretty soon.

I'm getting pretty tired
of just digging clay.

‐ As the team digs,

they notice the arrival
of unanticipated guests‐‐

local inspectors,

like the earlier
helicopter flyover.

This kind of unannounced
visit is unusual,

and it strikes alarm bells
in John.

‐ Normally, if there's
an inspection going to occur,

you know, they'll call me up
and say "Hey,

"we're coming out
to the site today

to give you an inspection."

These guys just showed up
out of nowhere.

They said, "Oh, we're here.
We're gonna inspect the site"

and, you know,
were just making sure

that we've got
all the right permits,

make sure that the use
of heavy equipment

and the people who are around it
are doing it safely.

We get frequent scheduled
visits from the government

to make sure
we're in compliance,

so inspectors showing up
just whenever they want

is something
we've never had before.

They're kind of looking across
at the different sites

with cameras.

You know,
it's a little disconcerting.

Yeah, falls is up
and over the top.

That's the plan,
so hopefully he can get

down underneath the falls
so he can‐‐

To work so close
to the water.

We're staying totally
away from the waterfall.

Makes me a little nervous

because we've got
a lot of things going on.

We can only be
in one place at one time,

and I can't keep an eye
on everything that's going on

at any given moment.

Maybe they think
we're getting close.

‐ Narrator: Following up
on Bingo's lead,

John and Rick reach out

to their new partner
Chuck McDougald,

a contemporary
of Robert Curtis

who hunted Yamashita's
treasure here in the 1980s.

He's agreed to lend his intel

for a share
of whatever they find.

‐ Charles McDougald is
a treasure hunter legend

in the Philippines.

He was one of the first people
to come here

and work at Fort Santiago
with Bob Curtis

trying to recover
a treasure there,

and he got really close
to recovering that treasure

before the government came in
and basically shut him down.

I've been searching for a way
into these tunnels,

but the map could really
be the key

to us actually getting
in there.

Good morning, Chuck.
‐ Nice to meet you, sir.

‐ Same here.

‐ We got the copy of the map
that you sent over.

It has really a lot
of similarities to our mountain,

especially in an area
that we call Breach 6,

and that's pretty intriguing.

We're hoping that you can
shed some more light

on some of the other features
on this map

and maybe help us
line that up

to what we have
on the mountain here

so we can actually start
building a scale for ourselves

and possibly confirm

that this map is actually
to this mountain.

‐ Based on the other maps,

which, you know,
very similar wavy lines...

‐ Waterfall‐‐
we've got that waterfall.

Hey, Chuck, you know,

we have waterfalls
on our property.

And we've done a lot of work
around this waterfall

'cause there are
a lot of rock markers there

that indicate that something
was going on there,

but there's still
no definitive way

to get in there.

‐ Well,
if you look at the map,

to me, that upside‐down "U"

could be a tunnel entrance
in the water,

and on each side
of this trapezoid

is a small ellipse,
four of them.

‐ Mm‐hmm.

‐ And those four
dark‐colored ellipses,

my theory is that they are
access points...

to going to the main tunnel.

‐ Well, in‐‐
in the center of the map,

there's a giant box there
with kind of an "X."

It's kind of shaded out,

and then it's got, you know,

four arrows
actually pointing to the box.

Do you have any idea
what that may indicate?

‐ The 20 or 30 maps I have,

all are very, very similar
with these markings.

I don't know for sure,

but the‐‐the‐‐the arrows
coming from each side,

my guess is
that's an indicator

that that's
a very important area.

‐ Mm‐hmm.

‐ Uh, why, we don't know yet.

But there could be
treasure in that area.

‐ Wow.

‐ It's hit and miss.

But I will say

you're on the right path.

But again, be careful.

‐ Chuck, I can't even say
thank you enough.

You've shed so much light

on something that was
a big mystery to us.

‐ Thank you. My pleasure.

‐ Narrator: The next morning,

excavation continues
at Breach 6.

After learning
the marble they found

originated in a rare quarry
in France...

‐ So, guys,
this nodular texture

that we see here

is very unique.

‐ ...Rick believes

they could be on the verge

of finally hitting
their target.

‐ Ever since we found
that marble,

I know that there's something
down this shaft.

We hit layer after layer
after layer of indicators,

so we think we're gonna
hit something significant

very, very soon.

‐ Winch her down for me, bud.

‐ Winch her down here?
‐ Pretty deep.

The plan this morning‐‐

we're gonna get
back in the hole.

We're just gonna dig.

We're gonna move muck
out of the hole

until we get
to the bottom of this thing.

Nothing too cool yet.

Hold that thought.

‐ What did you find?

‐ I think I got
a big piece of wood, dude.

‐ For sure.

‐ Oh, ah, it's a big one.

I got some timber, I think.

‐ What is it?
‐ Laying down.

‐ Oh, my gosh, man.

‐ I just hope it's not,
like...

the top of something.

‐ Does it sound hollow at all?

[ thump thump ]

‐ Oh. Ooh.
‐ Oh, yeah, that sounds hollow.

‐ Oh, it's hollow.

‐ Is he breaking through that?

‐ Dude, I just poked through it
with my shovel.

It's really rotten,
but there's, uh,

some kind of a void
underneath it.

You know,
I think I'd feel better

if you guys
would throw me a line.

‐ Farrell: Roger.

‐ Got to go
really careful from here.

I think we landed right
on top of a void space.

So if we can just keep
proceeding carefully,

we may be into this tunnel
in short order, hopefully.

It would be a good idea, man.

You don't need that bottom
dropping out from under you.

‐ You know what? Just give me
a little slack on the cable,

and I'll hook up to that.

Give me 2 feet.

I'm harnessing up here

because I don't want
to take the chance

and fall into something.

I mean, if it's holding up
the whole world,

I could be dropping down

20, 30 feet here if it‐‐
or farther.

‐ This could be it, buddy.

Could be it.
I'm hoping it's it.

‐ All right, I'm gonna try
to open her up.

‐ Ah, man, I'm shaking inside.

‐ I mean,
there's a hole there.

‐ See, that's a...
‐ Oh, my gosh.

‐ ...huge piece of wood, man.

Looks like there's probably
a cap sitting here.

‐ Keep our fingers crossed,
maybe we'll find a hole.

‐ At Breach 6,

Rick and the miners unearth

a promising new layer
of material

20 feet below the surface.

‐ Oh, my gosh.

‐ A huge piece of wood, man.

Ohh!

‐ Keep our fingers crossed.
Maybe we'll find a hole.

‐ Brent, is it hollow
underneath of it?

‐ All right. Got it.

So there's got to be
more down there, man.

‐ What do we have here?

It's round stock.

So that's round stock,
and it's laying down,

which is kind of leading me
to believe that it...

that this is
completely collapsed.

‐ Hey, Brent.

Yo, I just hit

a big old chunk
of round stock.

Uh, I'm kind of thinking
it's a cap

or a post laid over.

It's laying down completely.

‐ A cap is a broad
piece of wood

placed at the top
of a vertical post

to increase the surface area
it can support.

If this is a cap,

Brent may have found the top
of an underground structure.

‐ I'm gonna
send you guys up a load

'cause I'm running
out of bucket room.

‐ Okay.

‐ We've got some pieces
of timbering

from down the bottom
of the shaft.

We're gonna see if we can't
kind of fit this together

and try and make some sense
out of it.

‐ Yeah. That's‐‐I mean,
that's definitely a post or cap.

‐ I mean, look at the width
on that piece.

And this one looks
like it's burnt.

They could have burnt this wood
to harden it up.

‐ Preserve it a little bit.
‐ Preserve it a little bit,

make it, uh,
last a little longer.

Or they may have
blasted this thing shut or...

‐ Burnt it to the ground.
‐ Burned it to the ground.

I don't know what to think
at this point.

I'm starting to wonder
if this thing

might have been, like, a vault.

What it says to me‐‐

this was constructed
to house something,

and whatever it was housing
is still in that hole.

So somebody was trying
to preserve something

for a long time.

They had something
hidden down there.

We've found timber,

but we haven't found
any treasure yet.

This could be a tunnel.
Could be a room.

But until we get to the bottom,
we're just not gonna know.

‐ The next morning,
John and Rob set out

to check
if some of the indicators

on McDougald's map
[ drone buzzes ]

line up with locations
on the mountain.

‐ We have the Pyramid,

and we have
the waterfall site.

So if we can use the drone
to find some other markers

that may pertain to other
things on this map,

"A," it'll tell us

that this map is
possibly our mountain

and "B," those markers
that we do find

could correlate
to what's on this map

and may lead us to other
entrances to their tunnels.

‐ I'm coming up
on the river now,

and I believe I'm looking
at the waterfall

right in front of me.

‐ Hang over that waterfall
for a second.

‐ Let's look at that
in correlation

to what we have on the map.

You're on top of our waterfall.

That gives us
two points of reference‐‐

Breach 6 and the waterfall.

If that's the case, we should
be able to use the river

as a guide to try to figure out
those other symbols.

‐ John, looks like the river
bends back to the west

and basically heads
straight south.

What is that?

‐ Okay.

You know, that's‐‐

that's from the last time
we were here.

That's our drill tripod.

‐ Last year,

John and his team
drilled at a location

they believed to be
a Japanese tunnel entrance

called the Back Door.

‐ I think it's a void.

‐ But as they excavated
the area,

all they found
was murky water.

Thinking it was a dead end,

the team abandoned the site.

‐ Y‐You know,
that's‐‐that's weird

because that's‐‐that lines
right up to the map.

Check this out.

You came out of the bend.

Yeah, and you hit it right here,

and that's almost right
where the Back Door is,

and on this map is right
where this circle is.

According to Chuck,

a circle marker is a tunnel.

I think we should
revisit that Back Door.

‐ So far we've got
a pretty good perspective

on this whole map,

and everything on that side
has lined up.

‐ We know there's a cavity
at the Back Door,

and, as much
as we tried last year

and couldn't get into it,

I think
it's pretty significant

that it lines up
to McDougald's map.

Now more than ever,
I want to get back down there

and revisit this thing.

I think we walked away
too soon,

but now we have
the right equipment,

the right testing.

I think it's time
to get back down there

and try to get back in there.

‐ Later that day,

Rob checks
on the horizontal drill.

‐ We're over 200 feet in
at this point.

Everything's going well.

The core samples,
they all look really good.

We're really getting
back on track.

We're back in the rock
we want to be in.

‐ To keep the drill bit
lubricated

so it doesn't overheat
and break,

water continually cycles
in and out of the bore hole.

The water pumping
into the bore hole

has disappeared.

Andrew thinks
the drill punctured

an unexpected void space,

which the water is now
draining into.

But with their waterfall
target still 700 feet away,

this hole is
a complete mystery.

If the heavy drill bit
extends too far

into a cavity unsupported,

it could snap,

particularly if lack
of water circulation

overheats the bore.

This kind of damage
could keep them

from ever reaching
the waterfall.

‐ We're gonna mark out
the increments on the rod.

He's gonna push
a section through.

We're gonna take a measurement

and see how far across
it takes

before we're
at something solid.

‐ Well, we've, uh...

‐ What do we do now?
What happens if we keep going?

‐ Throughout the mountain,

the team is uncovering
incredible clues,

suggesting they could be
getting closer to the treasure.

But as excitement grows...

So too does the risk.

‐ You seeing that, bro?

Helicopter coming in.

‐ After receiving several
unexpected visitors...

John worries the multiple
warnings from Mr. X...

[ voice distorted ]

...and their new partner
Chuck could be true.

‐ And if and when they think
you've found a treasure,

they might step in

and either steal it from you

or just kill you
right then and there.

‐ As a result,

John's hired security

to safeguard the perimeters
of their work sites.

‐ To protect the site,
to protect our people,

you know, it's best to have
the right security team on site.

We got security posted

on every high point
in this place,

and I think we're good to go.

Treasure hunting in general
draws all kinds of people

and mostly unwanted people
to your site.

You know, you put
all this time and effort

and research into a project

to see fruition,

and they're just gonna wait

for you to do
all the hard work

and then just come in
guns a‐blazin'

and take it from you.

So anything we can do
to avoid that situation

is paramount here.

[ drilling ]

‐ Over at the tunnel,

father and son miners
Geo and Levi

continue to forge ahead
with the demolition robot.

‐ Working out here
in the Philippines‐‐

definitely different.

It's awesome getting to spend
this experience with my dad.

There's not another person
I'd rather have here.

‐ Yeah.
Knocking big chunks out.

‐ Surrounded
by unstable rock,

the pair remain vigilant.

‐ Part of mining, you depend
on your partner a lot

because, when you put on
that hard hat and that light

and you go underground,
anything can happen.

Watch out.

My dad worked in the mines
for almost 40 years.

Ended up
getting killed in a mine.

So I'm constantly
watching my son.

He's constantly watching me.

Working together,
I feel way more secure.

‐ Meanwhile, John and Rob
set up a bore hole camera

to examine
the mysterious void

the drill intersected

200 feet into the mountain.

‐ So now that we know

we've punched
into this void space,

we want to send a camera
all the way down there

and see what that anomaly is.

That's good.

Keep going.

Not down there.

‐ Looks like that's
about the end of it there.

It's getting‐‐
See that dark‐‐

‐ Yeah.
What is that dark hole?

Holy smokes.

That's a huge space.

‐ I didn't expect that.

‐ It's starting to look
more like a void space

more than it is a fault line,
Andrew.

When you guys said
you hit something

and lost some water,

I'm figuring
you hit a fault line.

See if you can twist it
a little bit.

‐ Hang on.

‐ Oh. What is that?

‐ What is that?

Let me see if I can get
a better look at it.

Right there.

‐ Oh, my God.

That is definitely
a piece of wood.

That's a timber.

Oh, my God.

That's a nail there.

You see it?
‐ Mm‐hmm.

‐ That looks
like a manmade tunnel.

Oh, my God. I can't believe
we're seeing this.

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

‐ Seeing all that wood

and seeing that it's
an actual tunnel,

my gut feeling is
that this tunnel leads

right to the waterfall.

They wouldn't have had this
in World War II.

I'm thinking somebody
was here before us.

‐ Japanese military criminals
confessed to save themselves.

That's how MacArthur got
the treasure.

‐ Is there any actual
evidence to back this up?

‐ It's kind of extraordinary
how much evidence there is.

‐ Get out of here!
