Pencoed Lead Works is a post-medieval and modern lead mine situated in Wales on bedrock of the South Wales Upper Coal Measures Formation. This geological sequence, deposited during the Westphalian period, comprises mudstone, siltstone and sandstone interbedded with coal seams, ironstone and ferricrete layers. Lead ore exploitation in this region exploited mineralisation within these carboniferous strata, which provided both the target mineral and the surrounding host rock.
The works represent industrial extraction during the period when lead mining became mechanised and integrated into Wales's expanding extractive industries. The site's operation depended on the accessible ore bodies within the Upper Coal Measures, where lead mineralisation occurred in association with the complex sequence of sedimentary and iron-rich deposits. The ferricrete layers in particular indicate iron enrichment in the geological column, a feature commonly associated with secondary mineral concentrations in coal measure terrain.
The monument is protected by Cadw, the Welsh Historic Monuments service, under the reference CM282. This designation recognises Pencoed Lead Works as a significant industrial heritage site reflecting Wales's important role in metal extraction and processing during the post-medieval period through to modern times.
