The monument comprises the remains of a 19th century lead mine including its water-management and transport systems, extraction and dressing processes with their power systems. It was established by the Dalrhiw Company in 1851 and was in operation for about thirty years. The mine is built onto a slope to the south of the Rhiwnant, the processing of the ore being assisted by gravity. The main shaft is at the top of the site, linked to the stream by a drainage adit. The remains also include a horse whim circle, stone lined bob pit, water wheels and pits, pumping gear, ore bins, crusher house, crusher house wheel pit, stone slab floor connected with jigs, mine office, trackways and leats.

The monument is of national importance for its potential to enhance and illustrate our knowledge and understanding of mining technology from a single period. Lead mines may be part of a larger cluster of industrial monuments and their importance can further enhanced by their group value. The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
