Hafna Lead Mine Mill is a post-medieval and modern lead mine situated in Wales. The site was worked to extract lead ore from bedrock comprising Caradoc Rocks of Caradocian age, a sequence of mudstone, siltstone and sandstone that provided the geological framework for mineral deposition in this region. The mill structures represent the industrial processing infrastructure essential to lead mining operations, where ore extracted from underground workings would have been dressed and prepared for smelting or market.
The site reflects centuries of mineral exploitation across Wales, where lead mining formed a significant part of the rural industrial economy. The Caradocian succession, though primarily sedimentary, hosted valuable metalliferous deposits that drew investment and labour to remote upland areas. Evidence of associated workings, settling tanks and mineral waste typically survives at such sites, documenting both the technical demands and environmental impact of the industry.
Hafna Lead Mine Mill is protected as an ancient monument by Cadw under reference CN326, recognising its importance as a record of Wales's extractive industrial heritage and post-medieval economic history.
