I have a broken hypothesis about the first mine. As you probably know better than I do, iron has several oxidation states that have different colors. I think the greenish rock contains iron that is less oxidized than the reddish rock. The spoils on the floor might be more red because it is more broken up so there is more surface area exposed to air so a faster oxidation reaction than the flat and mostly unbroken walls. So walls only had time to get to the green state and the spoils more red state. A less likely explanation maybe is there was a long fissure in the rock which the miners followed. That might also explain the odd placement of the entrance. Just armchair sciencing in unfamiliar knowledge areas so don't take me too seriously.
Is very nice straight adit. Stacked rock work instead of the labor of hauling it out is called gobbing. The end of a mine is called the face just in case anyone wanted to know.
Ahhh, lovely, cheered me up! I’ve got a cold, this is my best form of “medicine “. The shaft looks interesting, hope you guys manage to go down there, the wiggly quartz is fab. More ROVing, plus give us the shipwreck, we are still waiting!❤
I am always left with a feeling in awe-thinking of the effort that folks went through to create the mines. You two are really special and I’ve been following you forever. I can’t thank you enough.
Fascinating to see inside these tunnels and all the different features you guys pick out along the way. Congratulations to Helen, winning a great prize.
So that GBH 😊 is that worth checking out at some point by sending a camera down there maybe ?? That first mine got me confused with all that backfill on the floor like what were they encountering there? Big Up Rowan for his history on the mines he deserves a medal 🥇 cause he knows his mining history and I find it ever so interesting to hear 🙌🏻🙌🏻
If it weren't for the back fill on the floor, i wouldn't go in that kind of mine. I've one rule above all. No echo, no mine. Never got caught in one, but i explored a mine once figured no echo was present some 10ish meters in from the first turn to the right and i got out. A month later i learned from the owner that the ceiling had collapsed in that section nearly completely sealing it to the top.
Ioan has produced a beautiful book with lots of fascinating information about the mining community in the Plynlimon area and full of great pictures; well worth getting a copy.
Always enjoy the explorations! So, when a miner came to work at the mine you visited today, what would they see? Buildings? Just a hole in the rock? What kind of infrastructure supported the mining activity? Thanks
Ioan, do you have an Aberystwyth Railway steam train RUclips channel? I've learned a lot of interesting things regarding mining history on this channel. It would be interesting to see you showing us stuff regarding steam trains as well.
15:46 funny thing is, even tho the end is clearly different, the style of digging is the same. I'm wondering if perhaps this isn't a clandestine mining operation in a different portion and they used this line to fill up and hide the spoils. That would explain why there's no wheel ruts... if you keep filling over them, you can't see them. Is the area fully accounted for other holes? I know, crazy idea, but i've seen crazier mines. It would also explain why the walls are covered, but the spoils aren't. IF, this was done from the face of the mine outwards, then the oldest spoils would be equally covered or at least towards that. But those are fresh. All those chips are clean with only some water action on them.

Good on you for the book! This was an enjoyable walkabout for sure!
I really enjoy your explorations, and such a nice group of explorers. Thanks for doing this.
Congratulations to Helen!
Congrats Helen!
2 nice explores!
Thanks for sharing 🇨🇦
Always fun to go down a mystery mine, Who knows what you will find
Excellent video lads , really enjoyed it ,thank you 😎👍🙏
Lovely pair of mines to see, keep up the great work!
That was a brilliant video. Many thanks

WOW. You gave us 2 for 1. What a treat. Take care and stay safe.
Great video, love it being longer than usual 🙂

I Always enjoy your mine explores. Excellent video!
Good eye to see that leather, i bet there was one unhappy miner back in the day when their shoe broke haha, congrats to the winner :-)
Peace.. Shalom.. Salam.. Namaste
🙏🏻 😊 ✌ ☮ ❤
New to the channel, what great knowledge you all have. Full of facts. Love it.
Very nice, that is a big mine. Love the double. Thanks for sharing.
Ioan has produced a beautiful book with lots of fascinating information about the mining community in the Plynlimon area and full of great pictures; well worth getting a copy.
Shouldn’t you have swallowed a spider to catch that fly?
Yes
I knew an old lady who did that. I think she died 😢
Always enjoy the explorations! So, when a miner came to work at the mine you visited today, what would they see? Buildings? Just a hole in the rock? What kind of infrastructure supported the mining activity? Thanks
If you buy any of Ioan's books, then you will be able to see plans and historic photos of these old mines.
@@derekp2674 thanks!
I went down that winze last year, nearly completely plugged, and was too dangerous too try get through the debris, as was collapsing at the time
No debris in that one… and clean all the way down. Been down there now for a look and it’s a flooded level at the bottom…so a video for another day😉
Tantalising detail, looking forward to that installment.
The teeth are fascinating! Congratulations Helen, lucky winner.
Great video!!
Here in America, I’d be trespassing even thinking about an expedition into that GBH. Cheers for the wanderlust my guys and gal
Fantastic explores as always .hopefully you can abseil the vbh cheers Alan .

absolutely so beautiful-
Oh, I want to thank you for the CC option. I’m deaf as a rock
How did you not throw a rock down that hole, argh!
Swallow a spider to catch the fly!
When I saw the ladder I was trying to look up or down.
The "link" was the main part of a D shackle
Do you still plan to ROV the shipwreck that you mentioned in a previous video?
Ah, yes, this is Helen Barnes, I remarried & changed my name. I always wanted to be a Terry!
Funky intro that will get the hip kids in lol
Level is full of pirates, arrr that's where all the treasure is hidden 😂
How many hours in a day would they of spent working/tunneling?
maybe a slusher?
What no views in 20 seconds
Are you Going down it?....looks a horrible return back up.
How comes its always women you take with you? 😂
The lady is me…I’m Mrs Al…😊
