A single shaft mound remains on the edge of Crown Wood at SJ 1260 5675. Three additional shafts are located near Offa’s Dyke on Rhydwen Farmland at SJ 1330 7670, SJ 1335 7670, and SJ 1335 7660.

A few tons of ore were extracted at Rhydwen by the Lloc Mining Company in the 1880s, with further activity recorded in the early 20th century, as noted by Smith (1921). The shafts were still in use in 1899, appearin on Ordnance Survey maps from that period.
