[narrator] Previously on Mystery at Blind Frog Ranch.

- There it is. - Come on.

- Hey, stop! - Duane.

It's [bleep] broken.

We can't pull it out now, it's too unstable.

I think I may have missed something here.

These are images from the box.

The rocks inside the box are completely different

than any other rocks around here.

We need to get in there.

- Here at the box. - If that box is full of gold bearing ore.

It could be worth millions.

[laughs]

This is years of work that's gone into this moment.

They came from somewhere else.

These were put there by humans.

This has to be gold ore.

When you have ore, the real moment of truth

is when you break that thing open.

- What is this? - we got something really weird here.

Oh, my God. What the hell?

I can definitively say that this material is gallium.

We know for a fact that this box was over 500 years old.

Gallium didn't even exist then.

This project just keeps getting weirder.

There are some places on Earth that just don't seem...

right.

The land feels different.

It acts different.

And this here is one of those places.

Some say the land is trying to hold on to something.

Don't go in the [bleep] cave.

Aztec treasure.

Holy [bleep].

- Caverns of gold. - Look at that.

- Mormon riches. - It'd be million dollars here.

Some even say there's a buried space ship.

Hell, yeah.

Me? I never cared much about the stories.

I just care about finding whatever the hell's in the ground.

What's the matter?

- Gallium. - Yes.

Gallium?

So, does this rule out the Aztecs?

No, hell no, it couldn't.

The Aztecs knew what the hell they were doing

and they were clearly advanced.

And they might've discovered the metal 300 years

before nobody else even knew about it.

Well, yeah, I tend to agree.

I mean, we know that the Aztecs were really efficient metal workers.

But, what the hell did they use it for?

It's a mystery for sure.

Where do we go from here?

I mean, we only really have one option.

We got to get back into that cave.

We got to figure out a way in.

You know, there could be tons of that stuff down there.

Hidden in the bunch of those rocks down that cavern.

Yeah.

We need to round up the troops on this.

Oh, boy. Hey, fellas.

Well, we got some news for you.

Wait till you hear this.

- you know that metal we found in the rocks? - Yeah.

We put it through a bunch of tests, a lot of tests.

And we're 100% sure that it is the metal called gallium.

And, man, I'll tell you it's, it's some weird stuff.

It was morphing into different shapes,

- and saying... - pulsating.

It was beating, it was moving around.

Discovered by a French chemist in 1875,

Gallium is a soft, silvery metal with a melting point

of 85.6 degrees Fahrenheit.

It is a by-product of aluminum and zinc production,

but can also be created by smelting.

Ideal for carrying high voltages,

gallium is commonly used in electronic circuits...

semiconductors and LED panels.

Its military applications include communications, radar,

and electronic warfare.

But it is most sought after for incredibly efficient,

high tech solar panels.

It's real strange, because we've got this, this paradox there.

Gallium was only discovered in 1875

and we find it in an Aztec aged box underwater in a cave.

So, there's lots of questions we got to answer.

I mean, the process they found out in 1875,

didn't they have to smelt it?

- Yes, they-- - Didn't they have to work it to get that--

Yes, they did. Exactly. [bleep]

We're talking about 500 years ago.

So, they made this stuff basically.

- They had to. - That's what Eric's talking about.

They had to have some use for it or else

- it wouldn't have been down there. - Exactly, but why though?

- Yeah. - That's the question.

Yeah.

And who? Was it the Aztecs?

Well, they had to be fairly valuable to them

because they went to a lot of trouble to hide it.

I would think so. Yeah.

Yeah, there's no doubt something's going on there.

How much more of that stuff is in there?

Oh, there's rocks after...

- tons of rocks. - All the rocks we broke open had it in 'em.

I don't know where this is gonna lead us.

But I got a feeling it's right back into that cavern.

I don't know if anybody got any rest last night.

It's been quite a roller coaster, that's for sure.

- Yeah. - We know that the rocks themselves,

they're an ore.

But what is this gallium doing in the rocks?

It had to have some value to them back then

- Yeah. - In order to go to that much trouble.

- There's no telling what else is in here. - Yeah.

So, we know from carbon dating, the box is over 500 years old.

We know that contains rocks.

The rocks are used as vessels to hold the gallium.

Gallium's a rare metal.

You know, the Aztecs held their treasure in a cave

that had seven caverns.

Which is exactly what we have on this property.

So, yes, me.

You know, I want to know what else is down there.

We have two miles of these caves

and we haven't seen 1% of what the hell is in these cave systems.

We've got to fully explore this entire cave system.

- Oh, absolutely. - Because we don't know what is hidden in there still.

We need to be able to look at every point in that cavern

to find treasure.

We've been working on this project for about two years now

and so we've got some good data we've already done.

GPR, LiDAR, you name it.

But there's a lot more we can do.

We got to find that dry entrance

and we've got to... Yep.

So, last year, we spent months looking for a dry entrance

to the cavern.

- Come on, baby. - Where we could hypothetically

just walk in and not have to deal with diving.

Oh, yeah.

So, we're going to see what we can do to find

dry cavern under there.

And we'll drill our own hole, basically, creating our own entrance.

So, when we get the dry part, we'll be able to explore so much faster

and find out what's down there.

I think we can do it.

Ultimately, finding this dry entrance

is going to be a result of science.

I've got a lot of tools at my disposal

that will allow me to identify a dry entrance

to the cave system on the ranch.

- Okay, all right, let's do it. - Oh, absolutely.

But, we really need to be certain that

we're above a dry cavern before we start drilling.

Because every time Duane calls in a rathole rig,

it costs them another 10 to 20 grand depending on how deep that hole is.

The first thing I want to do is see what those rocks

can tell me.

When you're a geologist, you spend a lot of time talking to rocks.

Sometimes, they talk back.

Yeah.

All right, today, I took the rocks out that Chad pulled from the box

and I noticed what's called a sucrosic texture to the rock.

And that's a fancy word for sugary, sort of.

I haven't seen anything like this around here.

This is a metamorphic rock called quartzite.

It was once a sandstone, but then it was subjected

to heat and pressure.

And it sort of just melted it all together.

So, it's highly mineralized.

Great thing about rocks with a sucrosic texture

is the pores in these rocks pick up a lot of things

that are around them.

And so, one of the easiest things to look for is radiation.

Geiger counter measures radioactivity,

and that might be in the rocks.

This is a type of rock called quartzite.

And so, quartzite itself doesn't have any radioactive characteristics.

If the Geiger counter picks up radiation,

it means that the radiation is coming from the cavern itself.

So, if these rocks had been sitting in that cave for over 500 years,

they're going to pick up that radioactivity.

And so that will tell us a lot about the cave system.

Almost...

Yeah.

[Geiger counter beeps]

We're getting a little bit there.

Seems to be on the outside of this rock, sort of.

You can see the remnants of the gallium right there.

And there's nothing there.

When I put it to this rock again.

[Geiger counter beeps]

That's definitely radioactivity.

I think that could be significant.

I'm going to call in Duane.

Uh, Duane, do you copy, over?

[Duane] Hey, what's going on?

- So, I took out some of these rocks. - All right.

And I got the Geiger counter out.

Hear that?

[Duane] It's picking something up in it.

It's picking up trace amounts of radioactivity.

- Wow. - It certainly isn't enough to harm you

from a health standpoint.

- Right. - You know, I don't know if I'd want to be carrying

that around in my pocket for the rest of my life.

- But, uh... - Yeah, yeah.

Now, when we try it on the gallium...

there's nothing.

It's coming from the rock.

So, think of it this way. You take a rock that

has absolutely no radiation in it.

You take it and you stick it next to a nuclear reactor

such as Chernobyl.

So, when you pick up that rock, it'll have

all sorts of radioactivity in it.

And that's what's happened here.

This could be huge for us finding a better way to explore that cavern.

Oftentimes, in cave systems, caves follow faults.

It's a weakness in the Earth's crust, basically.

And radioactivity tends to find that weak zone.

Radionuclides will follow fault zones.

- Oh, really? - Yeah.

So, the idea here is if we find the radioactivity

that's seeping from the ground, we find the fault

and, potentially, the dry entrance to the cave system.

That's a heck... heck of a plan there.

- That's good. - It's worth a shot, right?

Oh, yeah, yeah. Wow.

Our ace in the hole is Eric.

If Eric can narrow down this search to just a few acres,

it's huge.

We don't want to tear this whole place up.

We just need to find a way to detect the dry part

of the cavern.

And then drill a hole and make an entrance

to the cavern, so that we can explore it.

And you can bet your ass we'll use every trick in the book to find it.

[Chad] I was over on the other side of the ranch.

Got a call from my dad.

Said Eric had some maybe, some good ideas

how we can find this dry entrance.

I mean, there's still a few things I think we need to work out,

but, scope, basically...

they may have something here.

- Tell us... - We need some good news, brother.

- What's happening? - Charlie.

So, um, I was looking at some of those rocks

that you pulled from the box there.

And I decided to run a Geiger counter over it.

And sure enough, we did find some radioactivity in it.

The rock itself was radioactive.

Was, like, last year, we found the radiation...

- Yeah, yeah. - Inside the cave though.

Exactly.

So...

the idea is if we can use a Geiger counter

to find the radioactivity, maybe we can find

the dry entrance to the cave.

I think Eric's definitely onto something.

I mean, since radioactivity underground can be detected

above the ground.

If we find the radiation, we'll find new entrances to the cavern.

I'm thinking of putting together a system

using an unmanned aerial vehicle.

If we can equip that with a radioactive detector,

the Geiger counter in essence.

Fly it low.

Maybe, we can plot what comes up.

Yeah. And then you zigzag back and forth and you could find your...

- Yeah. - Cave system.

So, you find the radioactivity, you find the cave system.

I think this may really help us narrow down our search.

We have to narrow it down in some matter,

the ranch is just too big.

Sounds like a hell of a plan, anyway.

Yeah, I'm gonna make a few phone calls

and see if we can line up a UAV with a radioactive detector on it.

Oh, let's do that. That sounds awesome.

- Sounds fine, too. - Good deal.

That's a good plan, Eric.

Now, let's get out of your hair and you make your phone calls

and see what we can get coming.

All right. Will do.

- Good idea. - Let's do it.

If we can determine where that radiation is leaking out

of the side of the mountain or something,

then that gives us a possible target that we can go dig at.

Hey Dad, you're around?

Where we going?

Okay.

I got the documents here to prove... system.

You can't be doing this [bleep] without me...

If you're taping this, you better tape it good.

I'm just, I'm just telling Chad, you're going to be served officially

with the lawsuit and we can do this hard way or the easy way.

My advice to you, get counsel and we'll settle it.

Are you [bleep] kidding me?

Well, I'm the new co-owner.

I've worked like a son of a gun for everything in my life.

I guess you can say it gives me a short fuse for freeloaders.

I kept this mother [bleep] going.

- Oh... it's all... - [bleeping]

You don't tell me a [bleep] thing about this.

We worked our ass off for this whole deal.

And you show up whenever things start going good.

Call me a liar.

Because you want some kind of [bleep].

You're gonna sneak up... [bleep]

That's what we're gonna do?

You long hair looking mother [bleep]. Come on, pull your gun.

Pull it.

Let's do this [bleep].

You know, it's really rare my dad gets heated like that,

but, uh...

he did.

Hey, Duane. Duane.

Just go, man. What are you doing here still?

We got your stupid ass papers. Go.

We'll see you in court.

Well, the judge will say stop

'cause the attorneys that I hire don't lose.

They don't lose. Bottom line.

Well...

he's not part of the ownership of the land

and that's, that's as simple as it gets.

There's people just coming out of the woodworks

that think they're kind of entitled to something like this.

We just gotta move forward.

Chad's right, there's not much we can do about freeloaders.

But, we have to do something about the trespassers.

That's, that's as simple as it gets.

[engine revving]

You know, I got Charlie putting more cameras up.

Problem with the camera is they don't stop anyone.

I think we need a few yards of fence here.

Guide people to the river here and the rocks there.

They're like, like dead ends.

- [helicopter flying overhead] - You hear that?

Holy [bleep], man.

Hey!

What the hell was that about?

I don't know, man. They were flying low as [bleep].

They weren't even 100 foot above that mountain right there.

I mean, legal limits are 500 foot at least.

- Y'all get that? - We did.

Those were Apache attack helicopters.

Four of them flying in formation.

Those were attack helicopters.

You know, a good friend of mine was an air captain

in the Marine Corps.

He told me that flying in a formation of four

is no more than just a decoy.

If they're moving people or supplies.

They'll fly in formation of four like that as a decoy

and, really, what's going on is a mile or two away.

No bull [bleep].

[man speaking]

We're the first ones in.

We didn't touch anything because it's obviously a mess,

but...

[sighs]

I don't know what's going on here.

Hey, Josh, have you seen the situation in here?

Oh, my [bleep].

What happened?

I don't know, we found it like this when we rolled in.

- [bleep] - I mean, do you think wind could have done this?

No. No.

That's, that's not wind.

No way. No way.

Did we have food in here?

We did. I mean, the food is over here.

- This is an event that didn't. - That didn't...

So, if it was an animal, they would have gotten into that, right?

Yeah.

It's a mess.

Anything looks like it's missing.

Yeah, we're gonna do that.

We might get some more trail cams and just keep them in here.

- Okay. - You know.

Those damn helicopters, they were [bleep] decoys.

Someone came in here looking for something in the crew's tent.

Maybe the footage of what's in the cavern.

Who knows?

Whoever did this tossed the whole tent around.

They didn't care if we knew they were there,

they were looking for something.

No question about that one.

- Hey, Jamie. - Hey.

Chad sent me the pictures.

What the [bleep] is going on?

Well, we had a little wreck up there at the tent.

It's got [bleep] everywhere.

They threw stuff all round, dumped tables over,

and what are the... what are they looking for?

I think they think we know something.

You know when I first got here,

I thought I could find a simple explanation for all of it.

But, it's clear this isn't your run of the mill place

with your run of the mill problems.

These guys are under surveillance.

I mean, the spy cameras they found.

The helicopters and now someone's getting into

all their equipment.

Who is it?

I want to help them find out to the best of my abilities.

I did talk to a guy by the name of Dave Miller.

You got all kinds of different government activity that's out here.

Just down the road, you have Skinwalker Ranch

which at one point was an actual science lab.

I can give you a number of somebody who I know

was involved at the time on the property.

- Just don't tell him you got it from me. - No, I appreciate that.

He gave me a name of a guy that used to work for Skinwalker Ranch

and he was a security guard.

And I'm gonna see if he can put some light on this

because I'm sure, you know, as somebody surveilling this area.

They might have been doing at Skinwalker too.

Yeah, could have. Could have.

He may know something or have an idea

or leads to, if some people are watching us.

The good thing is if they're watching us

this close, we must be doing something right.

And I like every bit of that.

Yeah.

Eric's got his aerial drone coming in with a high tech Geiger counter.

But, I don't want to just stand around here watch him do that,

so I'm gonna go old school.

So, we're looking for a new entrance to the dry part

of the cavern from the sky.

[engine revs]

You can cover a hell of a lot more ground

and see a lot more things.

And I haven't done an aerial survey in a year and a half,

so that's the plan.

Maybe we get lucky.

[indistinct chatter on radio]

So, I got this Cessna 182 right here.

It has bubble windows in it, so you can actually look over the side.

Perfect for sighting things and it's a high wing airplane,

so you can fly slow and low.

All right, we'll be over the ranch in five minutes.

So, part of the challenge here is this ranch is absolutely massive.

And the cave system is about, you know, two miles long

and 1000 feet across.

So, that's over 200 square acres to look for

a dry entrance point.

Since, we know that the cavern has radiation in it,

we find a seep at surface, we'll know exactly where to punch a hole.

There we go.

You know, that's got to be about the biggest drone I've ever saw.

That's great...

This thing costs a pretty penny.

So, we know that caves often form along fault lines.

Oftentimes, radiation is associated with faults.

So, I'm going to start by flying that drone along the fault

hoping to find some radiation.

We got a radiation detector we're gonna fix to this.

We're gonna fly it along the fault and test for radiation.

Those will be the most likely spots to have dry pockets.

Beats the hell out of walking with a Geiger counter in my hand.

But, there's something else that this Geiger counter

might be able to tell us.

It can tell us not only about radiation, a dry entrance,

but also about gold.

So, there's actually a theory called the Auger effect.

And it basically says radioactivity can be amplified in gold.

Now, we're in business.

So, gold would absorb more radioactivity than other materials.

So, the idea here is if we detect significant amounts

of radioactivity at the surface,

there could potentially be the dry entrance filled with

what I think is significant amounts of gold.

That's reading background radiation,

so that's working.

You see where the outcrop meets the valley floor there.

Yeah, that should be about the start of the fault area.

Okay.

Perfect.

Start going sweeping across it.

That's perfect.

So, just get an ambient...

not getting any spikes.

But, we're covering a lot of ground with this.

Come on, man, I want to see a spike.

Brian, could you possibly fly a little bit lower?

The lower you can get, the better.

Yeah, yeah. That's perfect.

[exhales]

Come on, man.

Wait a minute. There's a hit.

There's a hit right there. Brian, keep, keep doing

the same as you've been doing.

-There's another one. There's another one. -[counter beeps]

This is good.

So, what's this mean, Eric? Are we on top of it or what?

We could be.

We've got a good target to move on.

There's another one right there.

So, it's a big spike.

And that could mean either one of two things,

either excess or access.

It could be an excess amount of gold which could be

amping up the radioactivity.

Or it could just be a big, dry cavity underground

that's collecting the radioactivity.

Which would give us our access point.

- Yeah. - Awesome.

We got our target, boys.

That's some good stuff.

The deal that Eric set up, it's, it's amazing.

Technology is helping this whole deal move forward faster

than I could ever imagine.

Hey... camera crew right there.

How cool.

Hold on, man, you see that?

Doesn't that look like an opening in the ground right there?

Look at that, looks like a cave right there.

Just along that ridge.

Barely see it.

I'll steer it back, we'll fly right over it.

All right, sweet, just be right up in there.

Trying to look here.

There it is, there's the hole right there.

When I was flying over the ranch, I saw this big hole there.

That looked like there was an entrance,

a cavern maybe?

- [laughs] - I don't know.

So, I'm gonna haul ass to the ranch and check it out.

Hell yeah.

All right, guys, we're gonna head over to that spot

where we got the hit on the radiation from the drone.

Let's do it.

So, I found a nice big seep of radiation on one spot

on the ranch.

So, that to me indicates there could either be

a large case of gold down there

amplifying the radiation or a dry entrance to the cavern.

Hopefully, it's both.

I got the Geiger counter, I got field notes.

Sample bags, shovel.

Okay, all right. Good deal.

Hey, I think I saw something on the airplane

way over there.

There's a big cave looking thing.

I flew over a few times and I can see this, like,

hole going in the ground.

I think we need to go check it out.

- You got some landmarks? - Yeah, yeah.

There's a rock ledge and then there's two big trees.

So, why don't you take Charlie boy with you?

You guys go over there.

- And me and Eric go check out the other deal. - Yep, sounds good.

All right, let's do it.

So, Duane and I are heading to the spot on the ranch

where I detected radiation.

And Chad has taken Charlie to a spot on the ranch

where he detected something from the airplane.

We've got two targets right now and that's a good thing.

Final step is putting boots on the ground.

Right, Duane.

- You see it? - Yeah, I think we're pretty close

to where that drone detected the radioactivity.

I think it should be back in this direction here.

All right.

Let's grab the Geiger counter.

- Okay. - And the GPS and then the gravity meter with us too.

We're trying to pinpoint a place and bring in a rathole rig and drill down.

Hopefully, instead of drilling down into the flooded part

of the cavern, we'll get in to dry part of the cavern.

This way.

Then we can explore the cave system,

see what else is hidden down there.

You'll do your magic here.

Yeah, should be back in here.

All right.

So, this, let's, let's unpack this machine, maybe right here.

All right.

So, we know there's radiation seeping from a fault line in this area.

And that's a good indication of a cave system.

But, we really need to pinpoint the spot on the ranch

where this void may be.

I want to make sure that we're directly on top of that cavern,

because if you bring in that rathole rig.

You know, if we missed that hole, even by a foot or two,

it's gonna cost, like, 15 grand, and that's on me.

So, I'm going to use a gravity meter to see

if I can detect an opening under the ground.

Hit was right there.

So, I'm going to put it as close as we can get...

right in here.

So, a gravity meter can tell you the difference

between dense soils or rock and the cavity system.

When you have a dense object or dense rock or soil,

you'll have a higher number on the gravity meter.

Hollow spot underground will have a lower gravity field.

And will give you a lower number on the meter.

Perfect.

Yeah, turn it on.

So it's on, it's doing its thing,

and we've got a readout, a digital readout.

That's 25.3.

So, I'm going to call this G1.

All right.

Head it maybe over in this direction.

Then we'll go over there and we'll see what we got.

Okay.

So, to get the best results, we're going to take a number

of readings in the area and hopefully see something

that'll help us narrow down the location of the cave.

See now, this one's given us a little different reading.

So, this is generating some good data, I think.

We're looking for a place to drill a hole,

how close do you think we're getting?

This in itself is not going to tell us where to drill

and I know I want to get to a spot.

I want to find that spot and, so, it's just a matter of, you know,

first, you identify the large area and then as you do more

and more analyses, you focus in more and more.

We're still looking at the big picture here.

- Pretty wide spot. - I'd love to be able to tell you

this is the place to drill, but we're not quite there yet.

- Okay. - All right.

I just want to dig and get in there.

You know, this is a big ranch and we can't afford

to be drilling hundreds of holes all over the place.

I don't like waiting, but I feel like Eric can get us into the cave.

And hope the process pays off in the end.

[device beeps]

Wow, now, that's a lot lower.

That's significantly lower. That's a 16.

So, what are we talking about there?

So, what I'm seeing here is a very low number

to negative deflection.

There could be a cavity underneath us here.

Wow.

But we're getting strong results that could indicate

the possibility of a cavern beneath us.

I'm happy with this.

I think this could lead us to something pretty big.

I mean, I don't want to get too excited,

but I think it's worth running some more tests here.

We can only dig a relatively small hole.

So, we need to be dead on.

The more geophysical tests we can do...

the greater chance of finding it.

I'm really happy about the results of this gravity survey.

The instrument contains a highly accurate spring

and when you pass it over something of substantially different density

than the surface,

it'll give you either a positive or negative deflection.

Wow, now that's a lot lower.

And so, in this case, what we detected was an area

that's significantly more dense than the surrounding sandstone.

There could be a cavity underneath us here.

Wow.

The whole idea here is to find that cavern,

get into the cavern and see what's in there.

Wait a minute, there's a hit.

So, at this point, we've detected radiation

that's associated with the fault.

We've got a good target to move on.

Using science to find caves, and hopefully find the treasure.

Whatever it is, that's down there.

It's good stuff.

Oh, there's Jamie right there.

- Hey, Jamie. - Hey, Eric.

How's things going with you?

It's going good. We just finished what we've called a gravity survey

at the ranch.

And we came up with an anomaly actually.

And so there's something going on there.

That's really interesting.

A few weeks ago, I was led to a place here close by

and that's exactly what they were studying was gravity anomalies.

This is what I brought you out here to see, Jamie.

NASA?

The name of the location was gravity base furnell.

Gravity based furnell.

- NASA's been doing something here. - Interesting.

- Yeah. - Yeah, the survey I did,

it detects substantially different densities underground,

either heavier or lighter.

And we detected a heavier anomaly.

So, there's something heavier than the surrounding formation down there.

- Yeah. - I'll talk to you about it more.

I'm going into town, so we'll see you later.

- All right. - We'll see you.

Flying over the ranch, I saw a spot over there.

It looked like a freakin' hole

that went straight down.

Whoo-hoo!

Me and Charlie boy are gonna go look at this hopeful, dry entrance

and then we'll go meet up with the other guys on the other side of the ranch.

Oh, yeah.

Yeah, it is along this ridge right over here.

Maybe one of these either. Them or us will help us find

an opening into, into the cavern.

I could see it right on top right over here

when I was flying over.

Along those cliffs.

Yeah, yeah, yeah. It's right on the edge of those cliffs.

That was one of the landmarks right there.

That dead tree.

- Yeah. - And it's right along this ridge, right?

It should be right in here somewhere.

- Right on top of it. - Yeah.

So, if we can go down.

Right in there.

Is this it over here?

- No. - No.

It looks like a cave system, like, you could see dark area

- Yeah. - Right by it.

Yeah. Okay, here we go. Here we go.

That's it right there.

Wow.

[bleep] I thought it was a cave. It ends right there though.

Look how black all the rock is.

It looks burned.

Huh, look at this.

That's not a firepit, is it?

It looks... because there's so much burnt here.

Look at this, it goes all the way up there.

Yeah.

Yeah, all this charred, everything...

all this rock is charred here.

- [bleep] that's slag. - Yeah.

I see.

I wonder if we can age any of this stuff,

or see how old some of this [bleep] is.

You remember what Eric said about that gallium?

I mean, the process they found out in 1875,

then they have to smelt it.

- Then they have to work it to get that way. - Yes, yes, they did.

So, they made this stuff basically?

That's what Eric's talking about.

Ah, yeah.

They had to smelt that to make it, right?

Could this be a smelter?

Yeah, they could have smelted the gallium up here.

Yeah.

There's all kinds of slag in here.

This just wasn't a bonfire.

Smelting is a process that uses extreme heat

to extract metals from ore.

The first evidence of smelting dates to the Hittite civilization

in Turkey in 4000 BC.

Metals such as lead, copper, bronze, iron, gold and silver

are commonly smelted.

And it's the only way gallium can be created.

We've got this gallium that's only made by smelting

and now we think we found a smelter on the property.

Last year, we found a mine right above the cave.

I mean, this could have been, like, a full on mining operation.

They're storing their stuff in our cave.

I mean, we're literally standing on top

of an ancient cache of something.

Now, we just have to find out what and we've got to do it fast.

[narrator] Next time on Mystery at Blind Frog Ranch.

I think I found a smelter.

- Look at that. - Oh, yeah.

The mine entrance could be anywhere in here.

Oh, [bleep], look at those bats.

They move in caves.

I've never seen my compass act like this.

Is there an anomaly here?

Holy [bleep], look at this.

- Is that another one? - We have four smelters.

Cave opening's has gotta be somewhere right in here.

If he hits an anomaly, you'll see a big spike.

- It's dropping, dropping. - There we are.

Right there.

- We're right on top of it. - This is the best news we've had so far.

We're going to bring in the rathole rig.

And we're gonna drill a hole and get in there.

Where am I going with the rig?

It's gonna be right up on top of there.

If we miss it, it's just gonna cost us a fortune.

- [thuds] - Whoa.

Hey, let's shut this deal down.1
