Cwmystwyth mines are located in Cwmystwyth, Ceredigion, Wales.
Cwm Ystwyth is considered the most important non-ferrous metal mining site in Wales providing a premier example of mining heritage in Ceredigion. Within the site there is evidence for all phases of mining activity; from the Bronze Age, through the medieval period, to its revival in the 18th century and the peak of activity with a subsequent decline in the late 19th and the early 20th century. It has been designated as a Scheduled Ancient Monument. The site also features prominently in the Upland Ceredigion Landscape of Historic Interest.
Silver, lead and zinc have been mined in the valley of the River Ystwyth since Roman times, an activity that reached its peak in the 18th century. The largest of the very many mines was Cwmystwyth Mine. It is reputed that the average age at death of the miners in Cwmystwyth was 32, largely because of acute lead poisoning. There is no longer any active metal mining in the Ystwyth valley.
Water was extensively used during the silver and lead mining process to extract the ore. In the case of Cwm Ystwyth mine, much of the water was brought in by contour hugging leats from several miles upstream. The channel of the leat can still be followed on the hillside and is clearly visible from the road on the opposite side of the valley. Much of the water was used for hushing, prospecting and working the ore in the open.
In October 2002 the Banc Ty'nddôl sun-disc was discovered on the mining site. The disc is over 4,000 years old, which makes it the earliest gold artifact discovered in Wales.
