The recorded production figures in TOCMOS book suggest it is fairly large but from what I have read there is not much to see underground?

Hopefully it is worth the walk up Laugh

If anyone has any useful info that would help exploring please post!

It's been on my radar as a nice summer trip, possibly camping overnight, but didn't get around to it this year. After reading the same book I thought there might be potential for getting into unexplored sections by dropping into the rear of the stopes. IP: 147.143.12.215

I was there a couple of years ago. There is an (impassable) collapse around 50 feet inside. I think you "might" be able to work around it but it was really "dodgy". It may have got worse or it may now have been passed.

Usual water at the entrance which doesn't go over wellies but does go over "boots".

There are also a couple of short trials above the main entrance which I don't remember connected.

Good luck ... a trip report would be awesome.

Lovely surface remains and excellent geology to enjoy - it is worth the hike for that. I'd pick a nice summer day, though! IP: 86.170.18.159

From memory the adit is a drive on the lode that eventually opened into a narrow stope. Interesting explore but nothing really exciting.

Next visit I found the collapse and climbed above to find the source, which was a massive hole due to failure of 'rock stemples'. If I remember correctly this was a feature of the adit. Often seen around St Just in Cornwall in granite, but I fancy that the mudstones of Wales not quite as good.

I remember considering possibility of descending the hole, it may have collapsed more since then, but decided a way on at the bottom unlikely.

All this from memory and many years ago, so dont count on it as sound info.

Jon K has a better memory than me, but I recall there being quite a bit to see if you can be bothered to cart SRT gear up there.

There is quite a bit of interest on the surface, i.e. the remains of the crusher.

Rock at Lliwedd should be pretty good, Roy - it's all volcanics there, as opposed to the flakey mudstones down this way! IP: 86.170.18.159

I went for a bit of a reccy on this today.

Started out on the Watkin Path up to the waterfalls, crossed over and got distracted by some red tips on the hillside...had no idea there was another coper mine up there (turns out was hafod y porth) explored here a little. Has anyone been in the adit/tunnel beyond the flooded stope? there seemed to be a very very old piece of metal put across. some nice open stopes and what appeared to be fairly deep workings.

Anyway, onto Lliwedd. Approached from the top and explored my way down to the crushing mill. The open cuts are very imnpressive, very deep, easily explorable and doesn't seem too risky compared to some mines I've been in recently (ahem llanberis). Infact I spotted 'a number' of fairly recent bolts up there so someone has been having a go. The adit just above the crushing mill is blocked as mentioned above but it's not a loss really the workings are easily accessible by abseiling in further up, theres a track still in situ in the adit.

So in terms of gear - bolts, hangers, drill a couple of lengths of rope (40m should be fine).

The big downside is the damn walk, probably the most remote mine I have been to.

I got across years ago but cannot remember anything interesting so probably leads to a collapse.
Is there a truck just inside?

Do you mean Hafod y Llan SH625520?

(Hafod y Porth is in the next valley to the south at SH611508.)

We put all the bolts in a couple of years ago. All are 10 mm. You will need a fair bit of tackle to see it all. Avoid in heavy rain unless you like prussicking up a waterfall. We came out once after a day of serious rain and the amount of water coming down the pitch was exciting with voice communication impossible.

Good stuff Thumbs Up. I think I saw the waterfall you mean, there where two bolts placed above. I'll have to get myself back there!

I didn't actually go over 'sketchy as' but looking at the correct photo album it seems there was a truck over there.
