Small mine at the head of a small valley leading down towards Tylwch and appears to have worked the same load as Tylwch Mine. Plenty of Sphalerite to be seen on the spoil, which considering the age of theoperation, would have been discarded. With patience and some hard digging, some reasonable Quartz crystal groups can be found.
