Disgrifiad o´r Safle The Great Orme Copper Mines above Llandudno have an extensive complex of surface and underground workings exploiting copper ores in soft, easily worked strata. The true extent of mining operations here is unknown but it is believed to exceed 24,000 square metres, incorporating passages totalling more than five kilometres and penetrating a depth of seventy metres.

Archaeological evidence from the fill of the galleries include well-preserved bone tools and broken hammer stones. Charcoal was also found and radio-carbon dates from it have led to suggestions of Bronze Age beginnings for mining at this location. Spoil dumps and capped shafts are visible, dating from the nineteenth century.
