Carboniferous Limestone.

Workings
The Coetia Llys Mine was operating in the early 19th century, when the Coetia Llys or Cae llys Shaft as it was also known as, had already been sunk by 1838. The shaft is capped off and landscaped on a parcel of land at SJ06328085, which is encompassed by old peoples bungalows and their rear gardens.

Mostyn's Shaft sunk in the 1860s by the Talargoch Company worked the deepest part of the mine. Its engine house and chimney in the centre of Meliden were removed for a road widening scheme.

Transport
The remains of the mineral railway cuts the sett on its south-eastern perimeter.

Power
Two 36" rotary engines worked a winding drum and pumping gear at Mostyn Shaft, along with compressor and air drill. They were serviced by two Lancashire boilers.

Processing
Ore was dressed at the north-eastern end of the Coetia Llys sett. A siding connected the processing plant with the Prestatyn-Dyserth Railway. An 18" vertical engine and a 14" high pressure engine powered a Blake's Stone Crusher.

Other features
No evidence.
