ABSTRACT Over the last 25 years, new evidence has emerged of the scale of prospection for copper and its mining during the Early-Middle Bronze Age in Britain. We know of 12 mines worked in the period 2100–1600BC, whilst the largest mine on the Great Orme continued until the Late Bronze Age, with perhaps its maximum output which may have …
