Flooded pit. Remains of buildings.*

This small open pit operated sporadically from 1860 until 1915. Water power—likely delivered through a turbine—drove the mill, which housed two saws and two planers. A waterwheel supplied energy both for pumping and for running a chain incline, while a later addition of an oil engine powered the air compressor. Waste material was tipped to the north of the public road. Without any railway access, all slate produced at the quarry had to be carted by road to Talysarn station for onward transport.
