EPISODE 639 BARNEY DWAN 6: GOING UNDERGROUND IN IRELAND
sept. 8, 2022
After disovering the ‘Dead Cow Legend’ was true I began to pay closer attention to
the stories Barney Dwan told. This episode 639 led to a major
we were laying down a baseline across tiny fields close to the sea shore when Barney said
“Alan, how would you like together into the old mine?”
“Can that be done?”
“From the coast there are holes we can crawl through….I’ve done that many times.
“I’ve got in and out and am still living.”
“Let’s do it?”
“Tonight after work.”
Look closely … See Barney Dwan ewatinf jut below the old adit.
And so began my biggest Irish adventure. There was a hole halfway up the cliff face
not far from the knockmahon ruins. To get to the hole we could scale down from
the top of the cliff or scale up from the sea. The hole ws barely visible. A trickle of water
flowed out onto a grassy shelf. Hard to believe the hole was made by human beings.
An adit , designed to drain part of the mine or to get air into the mine. Perhaps both.
The hole was about three feet high. Occasionally higher. Most of our walk, however, we
were bent over. And we were careful. We had flashlights , candles and marches. Why candles?
To check the air quality. If the candle would light and stay lit, then there was no danger of
asphysiciation. If the candle would not light or suddenly went out then we should get
the hell out fast. No oxygen.
The walls of he passages were beautiful. Startling blue in place where the ore had not
been removed. Occasionally there were patches of pink
At one point the passage was blpcked by a roof collapse. Whoever dug this adit did not
use roof bolts or even timbers to hold up the roof. The blockage was a jumble of loose
rock and soft muddy detritus where water had percolated its way down and loosened
the ceiling enough for the roof to collapse.
FortunatelyThere was a gap. Just enough crawl space for Barney and I to pull ourselves through using our elbows .
and I followed. . The feeling of claustrophobia was almost
overwhelming . What if our bodies loosened more rock.? What if we got in and could not
get out? Did I tell Dr. Stam and John Hogan what we were doing? No, I did not. So
we were on our own. Now that was stupid. My only excuse is that I was 22 years old
an age when stupidity is commonplace.
The hole we crawled through using our elbows.
Once we got by the blockage we could almost standup again. Bent over though.
We crabbed our way along . I figured by then we were close to the
old mine ruins which were perhaps a hundred feet above us.
This was confirmed when we found a vertical shaft. Unsophisticated…almost natural.
But not so. Barney Dwan had been in here before and found a wooden ladder that
he placed across the vertical shaft. Easy to cross. If he ladder was rotten we would only fall a few feet because
the shaft was filled with water. Crystal clear water. Dazzling in our flashlight beams.
Was this one of old ladders used by 19th citify minders to reach the ore far below?
The mine had been exploited a lot deeper than this adit. So far down that the
stopes were some distance under the ocean. Flooding was one reason the mine was closed
in 1879. The other reasons was that the ore petered out. There was a likelihood however
that there were seams of copper under the ocean that were never exploited and never would be.
Pumps were necessary to tentatively hold back the ocean. When the pumps were shut down
the ocean has perfectly preserved ever since the closure.
The main stopes were far below us. Bunmahon Miners reached these mineralized sections by climbing
down long wooden ladders. In the dark One foot at a time on wooden ladder rungs. In the dark.
Between 1840 and 1879 there were no miners lanterns attached to helmets. Indeed there were no
(I will explain more about the 19th century Knochmahon miners in a subsequent episode. This episode is about
the adventureS that Barney and I had which triggered my curiosity about those 19th century miners
of Bunmahon. Where did they come from? Where did they go? What was their life like when they
lived here? Many came from the copper mines of Cornwall. Most of them migrated to various mines
in North America)
These are the ruins of the Knockmahon . Dr Stam and John Hogan are walking along
th e coast road now known as the “Copper Trail”, an UNESCO WORLD HERITAGE SITE.
The adit that Barney and I crawled through reached this ruin one shaft where the 19th century
miners had ladders to get them deep into the mine. Today the main underground
workings of this mine are perfectly preserved by tons and tons of sea water.
As I said, Crawling underground with Barney was a little risky. There was a feeling of claustrophobia
for sure but Barney’s cheerful presence reduced my fear and trepidation. Barney had been
here before and alone. He exuded confidence.
I did not tell our boss back in Canada, Dr. Norman Paterson, as i feared he would get his
underwear in a knot. Much later when I Told Dr. Stam and John Hogan about the underground
adventure they were both interested and amused. The oxidation on the adit walls…bright blue and pink,
confirmed that the site was worth the cost of our survey.
Miners drill holes for roof bolts to help prevent stopes and passageways from collapsing.
I do not remember any roof bolts in the abandoned Kn0ckmahon mine.
OTHER ADITS ON THE CLIFF FACE
I seem to remember entering the adit that is about 6 feet above the large ropeing on the ground.
.Thet adit led to the huge room inside with the slanted floor strewn with rocks.
THE I.R.A. HIDING PLACE, ACCORDING TO BARNEY’
(True or false? I would never know.)
“Alan, there is another tunnel you might like to explore just west of Bunmahon…a special place..”
“Story is told that IRA members hid there back in the Time of the Troubles.”
“Time of the Troubles?”
“Back in the 1920’s when Ireland was at war with England…civil war.”
“Very bad….Republicans needed a hideout and I was told this other adit was perfect.”
“True or false?”
“I think true. The story says this other adit became a safe place. Not sure if it was ever discovered by
the Black and Tans.
This picture gives a glimpse at what Bunmahon miners had to do using hand tools
and explosives. Mostly done in the dark with flickering light of candles and oil lamps. (The picture
is not from Bunmahon.9
The adit was almost too easy to fnid. Two entrances, one straight from the beach.
Easy to get into the front part but dangerous as we discovered when we reached a high vaulted room
with a sharply tilted floor that angled far down to some kind of iron machine. We never got that
far. The tilted floor the big room was littered with large chunks of fractured rock. Covered in rubble
in other words. Directy opposite our entrance tunnel was another tunnel at the same level. A continuation.
We decided to traverse the rubble cluttered sharply angled floor. To traverse we had to step on lots
large ( baseball to pumpkin size ) rocks piled helter skelter in the room which was about 20 to 30 feet wide and
af hundred feet long. Memory could be wrong about size. Maybe the room had been carved as a chute for ore to tumble down to some
kind of mechanical crusher at the bottom. That is just speculation.
Our tour ended abruptly. We were part way across the angled floor….tordding on the rubble. Pushing some out of the way
to get better footing. Then the whoile pile of loose rock began to move. Us with it.. Not far…several feet and
then the rock slide stopped.
Barney and I retreated with great care. We did not want to end our lives buried in a pile of rock at the mouth of
a rock crusher if that was what the iron framed machine was at the bottom of the angled room.
Maybe that pile of loose rock was a good way to discourage visitors. maybe there was an easy way around the
jumble. We did not the time to find out. Too dangerous. I may have taken pictures but cannot find them.
PERHAPS YOU WANT TO GO UNDERGROUND AT BUNMAHON….THERE IS A WAY TO DO THAT.
IF you want to go underground you can do so..virtually. Just punch up the “Copper Coast Unesco Geopark (Ireland)”
A film has been made of the underground workings at Tankardstown which is the 19th century mine east of Bunmahon
