This mine is just to north of a ford on a wooded hillside between the Llanrychwyn and Trefriw roads. The site is overgrown and fenced off. There are a number of shafts, all overgrown to some degree leading to stopes. At the eastern end is the stone lined, square Engine Shaft. Adjacent to the Trefriw road is the semi-collapsed, but still accessible Adit which leads to the bottom of the Engine Shaft. Given that the lode dips to the east, the westerly surface shafts (which are presumably old workings) must be shallower than adit level. There was also a nearby Roadside Shaft which was not located.



Named as working in the 1750s. During the early 1800s’, worked as a number of small bargains, with an attempt to rationalise into a more coherent working when Hugh Hughes comes onto the sett in 1853.

However not much was done until the formation of the Gwydyr Park Consols Limited Company in 1872 where it was worked with Park, Gwaynllifon and Gamfa Fawr.

In 1876, it was worked individually by the Clementina Lead Mining Company, and then in 1884-1889 by the Gwydyr Amalgamated Company where it was worked with Aberllyn and Gwaynllifon.
