To the west of the shaft, the foundations of the former boiler house are now grassed over. The Drawing Shaft remains fenced off amid trees, and the surrounding area consists mainly of grassed-over spoil mounds.

The site was served by the mineral railway along its eastern perimeter. The Scheduled Engine House, constructed from dressed limestone, remains a significant architectural feature. This three-story structure, built on solid foundations, contains remnants of its internal components, including the base of the 100“ cylinder and the engine’s plug rod pit. A date stone on the house marks its construction in 1860.

The Clive Shaft (SJ 0564 7998) and the Drawing Shaft, located to its southwest, marked the southwestern boundary of the mine workings. These shafts were situated on land known as Lletty Mwyn, as recorded in early maps (Mostyn MSS 1799). The Clive Shaft was sunk between 1842 and 1845 and remained operational until 1883. It is brick-lined on its northern side, adjacent to the Grade II Listed 100“ Cornish Engine House.

Originally, the Clive Shaft was worked with a 50“ hydraulic engine, but due to inefficiency, a 100“ steam engine was installed for pumping. Built by the Haigh Foundry in Wigan, the beam of this engine weighed 85 tons. The engine house was supported by a boiler house equipped with seven ‘egg-end’ boilers. In 1885, the engine was sold to Westminster Colliery in Gwersyllt. A horizontal engine was also used to power a capstan.

A leat, constructed in 1844, was designed to supply water to the hydraulic engine originally installed at Clive Shaft, which was intended to drain the western end of the mines. The watercourse was carried westward via a cast-iron aqueduct from a small reservoir. The leat originated from a sluice on the Afon Ffyddion, west of Pandy Mill Farm (SJ 0700 7920), passed under the Dyserth-Trelawnyd Road via a tunnel, and followed the hillside contours towards Dyserth Castle.
