Moving metals III: Possible origins for copper in Bronze

A recent evaluation of Bronze Age copper mining in Britain and Ireland (O'Brien, 2015:154) concluded that after 1500 BCE the only copper producing mine was the Great Orme in Wales. Copper production at the Great Orme started around 1750 BCE, and with total output estimates ranging up to c. 1800 tons, this mine was a substantial producer.
