Penmaenmelyn Mine;coba Copper Mine
Primary Reference Number (PRN) : 5502 Trust : Dyfed Community : St Davids and The Cathedral Close Unitary authority : Pembrokeshire NGR : SM71522360 Site Type (preferred type first) : POST MEDIEVAL Copper Mine Status : Pembrokeshire Coast National Park
Summary : A 19th century copper mine complex on the sea edge shown on the 1st edition Ordnance Survey map (1889) as Copper Mine Disused. The complex includes two areas of quarrying (PRN 99160 and 99161,) a shaft (PRN 99156) a self-draining mine tunnel called an adit (PRN 99159) and the stone foundations of two buildings (PRNs 99158 and 99155) and a revetment wall (PRN 99157). The first known reference to the mine is the St Davids Tithe award of 1841 where the map shows two small buildings marked as Cuba. The mine is believed to have ceased production in 1883 following a fatal accident. The complex takes the form of a level terrace aligned north to south supported by the revetment wall along the cliff edge. The remains of the buildings survive as low stone walls at either end of the terrace. The northern most building PRN 99155 encloses a now blocked shaft head shown on the early mapping. To the SW of this is the head of the shaft PRN 99156. This connects up with the adit which extends southwards emerging at a portal ovet a gulley on the south side of the complex. Both the shaft and the adit shows signs of mineralisation where ore bearing rock was extracted. The quarries lie on the eastern side side of the complex with the working faces facing inland. The remains of the walls and shaft are shown on the most recent Ordnance Survey mapping (Mastermap 2011). Recent aerial photographs show the site is overgrown with grass and other invasive vegetation. At a field visit in 2010 it was noted that some of the remains are eroding into the sea.
Description : Mine on very edge of cliff. Foundations of two stone buildings are present a small quarry and a shaft approximately 10m deep. A track leads down to the workings. The site is eroding into the sea. Two small buildings named Cuba marked on the St Davids Tithe map. Murphy 1996
