Speaker Biographies

Paul Agnew headshot

Paul Agnew

Paul is a geologist with more than 25 years of experience in minerals exploration with Rio Tinto Exploration. As Chief Geochemist for RTX, he spent more than a decade providing technical support to exploration programs for a wide range of commodities globally, as well as developing and implementing best practice in geochemical exploration throughout the organization. In 2010 he took the role of Chief Geologist-Technical Support and Technology Development, leading a team of technical specialists providing global support and managing internal and external R&D activities, focused on the delivery of innovative exploration technologies to improve the efficiency and effectiveness of mineral exploration.

Rodney Allen headshot

Rodney Allen

Rodney (Rod) is an Australian geologist with about 37 years of experience in mineral exploration and research applied to mineral exploration. For most of his career, he has straddled the fuzzy boundary between exploration and research, hopping from one to the other, or often standing with a foot in each. He received his B.Sc. at the South Australian Institute of Technology (formerly South Australian School of Mines) and worked a stint in exploration for Selection Trust and BP Minerals, before doing a Ph.D. and postdoc at Monash University on the volcanic setting of VMS deposits in Victoria, Tasmania, and Japan.

Since then, Rod has worked around the world as a consultant geologist for almost 20 years, carrying out assignments for mining companies, universities, and government agencies. Rod has enjoyed a long-term relationship with Tasmania and with the CODES research centre. He is perhaps best known for practical skills in interpreting volcanic successions, hydrothermal alteration, and the ore deposits that occur in them, having had the joy (or misfortune) to try to unravel the stratigraphy and structure of several strongly altered, deformed, and metamorphosed volcanic-hosted mining districts around the world. He has published the results of many but not all of these studies, especially in the SEG's journal Economic Geology.

Rod is currently adjunct professor in economic geology at Luleå University of Technology in Sweden, where he supervises Ph.D. students, and is Manager Geology R&D for the Boliden Mining Group.

William Clarke headshot

William Clarke

William (Will) graduated from the University of Melbourne with a B.Sc. (Hons.) degree in geology in 2006, before commencing work as a graduate with Newcrest Mining Limited in 2007. Since then, he has worked as a mine and exploration geologist on various styles of gold and copper deposits in New South Wales, Western Australia, Indonesia, and Fiji. More recently, Will has been working on the applications of Corescan hyperspectral data, focusing in particular on geometallurgical implications such as understanding fluorine deportment at Cadia East and improving alteration modeling at Lihir to support mining and metallurgical decision-making.

Andrew Davies headshot

Andrew Davies

Andrew began his career in 1987 working as a field assistant for junior companies Cominco and MDRU on remote grassroots programs in western and northern Canada. Following completion of a B.Sc. (1994) at the University of British Columbia, he joined Kennecott Exploration (Rio Tinto) working in Canada and Central America on epithermal and porphyry projects. He completed a Ph.D. (2002) at CODES on Rio Tinto's Kelian epithermal gold deposit in Indonesia. This work led to a passion for integrated deposit- to district-scale thinking focused on the interplay of structure, hydrothermal system evolution, and brecciation processes. Following time in Peru with AngloGold, Andrew joined Teck Resources Limited in 2004. Since joining Teck, he has worked internationally in a variety of technical roles spanning epithermal, porphyry, and SHMS Zn-Pb systems, was General Manager Exploration for North America from 2007 to 2012, and is currently Teck’s Chief Geoscientist. In his current role, Andrew is responsible for geoscience leadership, leading practice development and geoscience talent development as foundations for success in exploration and deposit evaluation.

Cornel de Ronde headshot

Cornel de Ronde

Cornel is a Principal Scientist at GNS Science in Lower Hutt, New Zealand. He leads the offshore minerals team there and, together with his team, has worked on numerous seafloor hydrothermal systems related to submarine arc volcanoes around the world. These include volcanoes of the Kermadec, Tonga, Mariana, Aeolian, and Tabar-Lihir-Tanga-Feni arcs. The team has systematically surveyed the entire length of the Kermadec arc and half of the Tonga arc for hydrothermal emissions. In total, in collaboration with international science partners, they have surveyed about 150 submarine volcanoes. More recently, de Ronde has worked in the NE Lau back arc and the Colville Ridge. Surveys were initially conducted from surface vessels, but, more recently, de Ronde and colleagues have focused on using deep diving vehicles, such as manned submersibles, ROVs, and AUVs, to provide information at a scale relevant to mineral deposits and to sample the hydrothermal vent systems for their fluids, rocks, and minerals. In addition, these near-seafloor surveys enable high-resolution bathymetric, water column (for plumes), and geophysical surveys (e.g., magnetics and side-scan sonar) to be done, allowing hydrothermal fluid upflow zones (and associated mineralization) to be delineated. de Ronde has co-edited a special issue in Journal of Geophysical Research and two others in Economic Geology on seafloor hydrothermal systems related arcs and back arcs.

Kathy Ehrig headshot

Kathy Ehrig

Kathy received a B.Sc. in geology from California State University, Fresno in 1984 and a Ph.D. in geology from the University of California, Berkeley in 1991. She began her career as a Geological Technician with the United States Navy in 1974, then went on to work with WMC and, later, BHP Billiton as Principal Geometallurgist at Olympic Dam. Her accomplishments at Olympic Dam and Yeelirrie have included leading the team that developed the geometallurgical models and metallurgical performance predictors for the entire Olympic Dam deposit, establishing the mineralogical relationship between sulfide mineralogy and concentrate grade, and developing quantitative relationships that predict mineral abundances based on drill core assays. At Yeelirrie, she developed the metallurgical performance predictors for a calcrete-hosted uranium deposit and built the world’s first clay mineral model for an entire deposit, which involved innovative adaptation of existing technology. She is a member of the Society of Economic Geologists, Geochemical Society, Geological Society of America, European Association of Geochemistry, Mineralogical Society of America, Mineralogical Association of Canada, and Australasian Institute of Mining and Metallurgy.

James Mungall headshot

James Mungall

James received a B.Sc. in geology from the University of Waterloo in 1987 and then did M.Sc. and Ph.D. theses at McGill University. His early interests in rare subalkaline intrusions gradually morphed into a fascination for non-equilibrium processes in magmatic systems, which he pursued in his postdoctoral research at the Bayerisches Geoinstitut. In 1996, the world of mineral exploration tempted him away from academia for a couple of years until, in 1999, he found a niche at the University of Toronto where he could apply field, theoretical, and experimental approaches to the study of magmatic ore deposits. After spending several field seasons combining consulting and research on Ni-Cu-PGE deposits in northern Canada, he took a one-year leave of absence in 2008–09 to serve as Chief Geologist at Noront Resources Ltd, overseeing the geological staff working on Ni-Cu-PGE, Cr, and Fe-Ti-V deposits in the McFaulds Lake area of Ontario. He has since returned to the University of Toronto, where he holds the Norman Keevil Chair in Ore Genesis.
