Pit/underground, with incline and drum.**
Worked sporadically from the 1860s onward, initially operating as a hillside operation where slate was dressed by hand. The opening of the Ffestiniog and Blaenau Railway prompted a transition to deeper extraction methods, with the quarry expanding into pits and subsequently developing underground workings. Production peaked in 1872, when a workforce of 30 men extracted 532 tons of slate.
