Penmaenmelyn Mine; Coba Copper Mine Adit
Primary Reference Number (PRN) : 99159 Trust : Dyfed Community : St Davids and The Cathedral Close Unitary authority : Pembrokeshire NGR : SM7152323570 Site Type (preferred type first) : POST MEDIEVAL Adit Status : Pembrokeshire Coast National Park
Summary : Rock-cut adit, open, dry: appears to have been driven southwards from shaft and to have either intersected a natural cavity at the head of this natural sea-eroded gully (any cavity may well have been widened to create the current portal), or to have been retrospectively driven through to this gully as the level is not aligned on this gully, trending SSE and missing the gully, ending at an underground socket just East of the current portal. Mineralised veins are exposed at the head of the inlet, just northwest of the adit portal. See PRN 5502 for further references. K Murphy based on Protheroe Jones 2010.
