Cwm Erch Copper Mine is a post-medieval and modern copper working situated in Wales. The mine exploits copper mineralisation hosted within mafic tuff of Ordovician age, part of the unnamed extrusive rock sequences that form the bedrock across this region. These volcanic rocks were laid down during the Ordovician period and have weathered over geological time to create the distinctive landscape of the Welsh uplands.
The mine represents the industrial exploitation of mineral resources that became intensive during the post-medieval period, when demand for copper increased substantially. The site preserves evidence of the mining techniques and workings associated with this phase of exploitation, with physical remains visible across the landscape reflecting both historical and later phases of extraction.
The monument is protected and managed by Cadw, the Welsh Historic Monuments Service, under the reference CN193. This designation recognises its significance as an industrial heritage site, preserving the physical remains and landscape character of copper mining within Wales's rich mineral heritage.
