Name(s) in local language(s):
Esgair Lle Mine
Beside the A44, 1.5km east of Ponterwyd where the small side road turns south to Devil's Bridge.
The mine appears to have worked an east-west lode that runs obliquely up the hillside and is marked by a series of fenced off shaft collars and towards the crest of the hill by a large scar (behind the large shed at the time of writing), possibly left when a stope collapsed below ground. An engine house stands centrally in the site and adjacent to this is a wheel pit. The 1887 OS map shows an aqueduct feeding the wheel with branched aqueducts further up the hillside.
The foreground of the site between the engine house and the A44 road is principally mounds of stamp sand which has been spread over time to cover most of the area in a thin dressing. When the small river runs along the bottom of the site the deposits can be seen as distinct layers with fine slimes at the bottom and coarser sand washed over the top.
The tips appear to have been more extensive until quite recently with a great deal of fresh digging and levelling having taken place on the slope between the engine house and the shafts. The tips offer abundant sphalerite, whilst chalcopyrite and galena are found as occasional grains.
Further buildings including possibly a wheelpit are at SN778814, 500m east-north-east of the engine house and are also shown as part of the West Esgair Mine on the 1887 OS map. These are presently in the corner of a grassy field without any open tips.
