ABSTRACT
The major deposits of tin ores in Western Europe are very limited, and Devon and Cornwall are among the very few places where primitive peoples could obtain such ores in the British Isles, although small amounts of tin ore have been found in the Wicklow gold deposits. 1 Excavations at Chûn Castle 2 showed that smelting was carried out in the pre-Roman Iron age (3rd-2nd century BC), and a La Téne-type brooch was found associated with slag near St. Austell. 3
