A range of buildings perched on the edge of the former main quarry pit (now a tidal pool) between the pit and the sea. Consists of a one or possibly a two storey building with gable roof - probably the engine house, and another rectangular structure built right at the edge of the pit which has walling extending right down into the pit itself - probably the remains of the "lift". Both structures are clearly shown on the earliest 25 inch OS map. Built of local black sedimentary stone. The larger building is about 19m x 6m and smaller (lift building) about 9m x 9m. Both structures were at the terminal point of the tramway linking the site to Porthgain harbour (NPRN 400060).
