Untopped in the 1990s. The remaining bits of buildings are from that period.
There is little evidence of the smaller scale older underground slate working and most of the easily accessible parts are flooded.



Originally worked intermittently underground. Briefly re-opened in 1987 by some local miners before the site was sold and largely destroyed and flooded by untopping.
