Richard Sillitoe

Independant consultant

Dick Sillitoe is the world’s leading expert on the geology of copper deposits, especially porphyry style deposits.
After a start with the UK Ministry of Overseas Development studying supergene enrichment of copper deposits in Chile from 1965 to 1968, followed by three years with the Instituto de Investigaciones Geológicas (Chilean Geological Survey) studying porphyry copper deposits, Dick became an independent geologic consultant in 1971.  He has published 120 technical publications in international journals, books, bulletins, and conference proceedings. He has also written more than 800 unpublished technical reports while consulting for over 200 mining companies, seven governments, and four international agencies in 97 countries around the world.
When not working in the field or writing up his observations, Dick has committed his time to education in economic geology. He has been an invited speaker at 95 international conferences to date, co-convened five major conferences, presented 40 public lectures at universities, geological surveys, and scientific meetings, given 16 short courses at universities, geological societies, and conferences, delivered 45 in-house courses for mining companies, and run 17 field courses for mining companies and other organizations.
