Some buildings remain and these appear to have been built as a second mill and workshop area. However, the buildings show no sign of any equipment ever having been installed and no ash was found in the area of the ‘smithy’ or ‘engine room’. The hillside waste fingers are cut by the original incline. The best known feature of the site is the ‘binoculars’ - two parallel machine bores, which were cut through by later surface work. At least one other short machine bore is evident. On the side of the mill foundtion are a set of slate steps. At the end of the mill the wheelpit shows that the wheel was at some point enlarged. This is likely to have been when it was also required to power the uphaul incline which remains eveident.
Terraced pit working with some underground work which was subsequently lost by further surface activity. Rock was initially brought down by an incline though later this went out of use and a tramway adit and uphaul incline were used. Waste was carried out on the gallery contours with mill waste run downhill and over the river and road. The huge retaining walls for this mill waste were removed during landscaping and road works. A substantial waterwheel driven mill was built on the waste - the mill was flattened in the 1990s when the area was bring considered for dumping (in the way Gaewern had been used). Working was intermittent and largely unprofitable. Two periods of significant profitability occurred, one in the 1870s and then a second brief one when the Penrhyn Quarry strike was in progress.
No officially sanctioned access but there is no attempt to prevent access and the path into the pit is very well trodden.
