The Hafan Lead Mine was by worked by Mydelton under the name Caninog / Coninog / Kaninog (the name may also refer to the district vein (Foster-Smith)) in trial workings, in the seventeenth century . The site was subsequently worked by Waller.

Lead, zinc and copper ore were produced during periods when the mine was operational - 1850-54, 1857, and 1863-5, 1897-1900. Surface remains include a wheelpit, cratered sites of shaft and level entrances, dressing floors and extensive workings and tips-screes.
