Rhiw Rugos (Erwtomau) Mine (SN 712 782)
This is a densely mined area with several small mines. The mines were worked separately in their earlier history; in later years most were worked together as the Rheidol United Mines. My thanks to Ioan Lord, Cwm Rheidol, for his assistance with identifying the location of these mines.
