The Curse of Oak Island: MAN-MADE TUNNEL EXCAVATED (Season 9)

Here we go, we got a core.
See what lay your luck gives us, yeah?
Terry Matheson and Charles Barkhouse are supervising the core drilling operation of the team’s latest borehole in the C1 cluster known as CD 4.5.

What you got, Adam?
78, 78.
Thanks.
Adam, let’s open her up.
We got some wood here, Terry.
What’s the approximate deck?
That’s 78. What do you want to call it?
75.
Call it 75.
See what’s going on, yeah?
We went from very dense clavich tilt into a section of beam or wood or some kind of timber.
Meaning boating well for that being an in-place structure.
A ton of perhaps…
It’s possible, yeah.
A possible tunnel found at a depth of 75 feet in borehole CD 4.5.

Because the team has recently drilled through another believed tunnel some 15 feet deeper in this area, could that mean they have now encountered yet another man-made structure?
If so, might it possibly lead to the source of the silver and gold they have also detected?

Hey, Scott, check it out, guys. This guy we just pulled on the party. Kind of an interesting find here, yep.
Well, if there’s any metal in this, that pinpointer will find it.
Finding anything?
I got a hit here, but I’m trying to determine whether it’s a screw in the table or lift it up.
Yeah, yeah. There’s something in here, there. Yep.
It’s in this piece, whatever it is.
A little piece of metal.
What the heck that is?
I don’t know.
A metal object also discovered with possible evidence of a wooden tunnel some 75 feet deep in borehole CD 4.5. Great find, Charles.

We’re very interested in this C1 cluster area because we’re getting a lot of wood hits, and we’re finding pieces of metal.
Bag it, tag it, and have Kelly look at it. Yep.
But what’s even more interesting about it is we have no historical record of any work being done in this area.

Hey, Rick.
After being alerted of the new and potentially important discoveries, Rick Lagina arrives to inspect them and receive a detailed report.

So, CD 4.5…
We hit wood at about 74 and 75 feet, and we also found a chunk of metal. This was at 75 and a half feet.
It’s encrusted, so it’s really hard to tell what it is, but it does have some weight to it.
Yeah, it does. It does. Yeah, it’s hard to say what it is.
Certainly not from the rig.
No, no.
Another mystery, yeah.

Although finding evidence of a tunnel along with metal at a depth of 75 feet in the Money Pit area offers the team hope that they could be close to a major discovery.
Three weeks ago, while drilling in borehole D2, just 13 and a half feet to the southwest at a depth of some 90 feet, they also obtained evidence of another wooden tunnel that dated to as early as 1488, as well as a mysterious piece of metal that contained a significant amount of gold.

Is it possible that both of these potential tunnels could be connected to the original Money Pit?
I think based on everything we’ve learned, the interesting metals in D2, perhaps this will be a surprise as well.

So, I’m going to take this on the archaeology trailer and then put this under XRF.
Okay. All right, thank you, guys.
See you, Rick.
Yep.

Later that afternoon, following their discovery at CD 4.5, hey Rick and Charles meet with Rick’s brother Marty and professional conservator Kelly Barasa at the archaeology trailer.

What do you guys got?
I found another piece of metal.
This could be good.
The unusual thing is 75 and a half feet because the tunnel horizon is 86 to 93.
Yeah, so what’s that doing there?
Yeah.
Let’s see it.
Looks cement-like on the surface.
I don’t think there’s much cleaning can be done.
Nonetheless, we can still test it with the XRF.
Okay.
See what it says.
Absolutely.

Using an X-ray fluorescent spectrometer, or XRF, Kelly will conduct a chemical analysis of the encrusted object.
The device works by emitting non-destructive radiation, which can identify the elemental composition of metal objects.

There we go.
Iron. That’s not a shock.
Yeah.
Whoa.
Hey, you!
That’s gold.
How about that?
