In September 1986 a small excavation was done by S. T. to investigate an area of primitive-style mine-workings on Copa Hill, Cwmystwyth, Dyfed (SN816756). A small opencast and several overgrown tips associated with pebble hammers occur where the copper-rich Comet Lode outcrops on the brow of the hill. Copa Hill is within an area of seventeenth–twentieth-century lead-mine workings which extend for 1.2 km along the N side of the Ystwyth Valley (fig. 1). Radiocarbon dating of charcoal from within one of the tips suggests that mining commenced in the middle Bronze Age.
