Since taking early retirement in 2012 he has been applying his expertise in geochemistry, ore geology, mineralogy and pyrotechnology to important archaeological challenges in the field of prehistoric metal mining and smelting. He has written several papers and three books on historic and prehistoric metal mining areas in Britain and Ireland. He also has a long-standing interest in Bronze Age tin since working at Wheal Jane tin mine in Cornwall as a student geologist over 40 years ago.
