Over nearly 50 years Dick Henley established an international reputation as an applied scientist in the economic geology and geothermal energy sectors and is particularly well known for innovative and practical solutions of complex problems relating to hydrothermal processes at all scales, and their exploration.
Following a PhD at the University of Manchester he moved to New Zealand as Lecturer in Applied Geology at the University of Otago. He moved to Wairakei in 1977 to join the Geothermal Research Group and was subsequently appointed Group Leader. He was a founding lecturer at the U.N. Geothermal Institute at the University of Auckland. Through 1983-84 he was a Fulbright Scholar in Washington with the US Geological Survey.
He moved to Australia in 1986 as Chief Scientist in the Bureau of Mineral Resources. From 1988 as Managing Director he initiated and developed a global consulting business in the minerals industry – SRK Australasia As a consultant, he is credited with direct involvement in a number of gold discoveries, including the world’s largest on Lihir Island, Papua New Guinea, and consulted to the UNESCO and UNDP in Central and South America and SE Asia. In 1995 Thayer Lindsley Speaker of the Society of Economic Geologists.
Dick Henley also became an experienced independent company chairman, including for a Canadian gold exploration company and Australia’s $ 11b Naval Shipbuilding Program. For several years he taught a range of governance disciplines on behalf of the Australian Institute of Company Directors.
Following retirement in 2007 he joined RSES as a Visiting Fellow and continued research into the understanding of high temperature gas plus solid reactions with a focus on processes inside active volcanoes.
