Date: Thursday, December 8, 2022

Time: 1:00pm - 5:30pm MST (UTC-7)

Location: Online using Zoom

This free symposium will consist of four 45-minute lectures, each followed by a moderated 15-minute Q&A session with the audience. The webinar is available at no cost to attendees. Advance registration is required.


The 2022 SEG Distinguished and Traveling Lecturers are providing a virtual symposium showcasing their premier talks and offering a great opportunity for a worldwide audience to engage with them through immersive presentations and interactive discussions. Each lecturer will provide one 45-minute presentation followed by a question and answer session.

The SEG Lecturers are globally recognized individuals that serve as ambassadors for the Society. Lecturers are excellent speakers selected each year based on their significant contributions to the field of economic geology. The SEG Distinguished Lecturer and Traveling Lecturer Programs provide support for the lecturers to present to SEG Student Chapters, universities, and minerals industry events around the world. This symposium will continue the mission of the program to reach a broader audience, especially to students and early career professionals.

SEG Distinguished Lecturer


Elizabeth A. Holley

SEG Fellow

Talk Title

Responsible Critical Minerals: Transforming Mining for the Energy Transition

Dr. Elizabeth Holley is an exploration and mining geologist who studies the processes responsible for ore deposit genesis, as well as the geologic characteristics that determine how orebodies are developed, mined, and reclaimed. She is an associate professor jointly appointed in the Department of Mining Engineering and the Department of Geology and Geological Engineering at the Colorado School of Mines, USA, and she serves as the site director for the National Science Foundation-funded Industry-University Cooperative Research Center for Advanced Subsurface Earth Resource Models. Dr. Holley's interdisciplinary work examines the intersections between technical and social risks in mining, and she is a fellow of the Payne Institute for Public Policy. Dr. Holley's Mining Geology Research Group is supported by the National Science Foundation, CDC NIOSH, NGOs, and the Center for Mining Sustainability, as well as major and mid-tier mining companies. Dr. Holley has worked in the industry on five continents, and she contributed to the discovery of the White Gold deposit in the Yukon. She is a fellow of the Society of Economic Geologists and has organized nearly 200 professional development short courses for SEG.

International Exchange Lecturer


Keiko Hattori

SEG Fellow

Talk Title

Magmatism Linked to the Formation of High-Grade Epithermal Gold Vein Deposits

Keiko Hattori received her Ph.D. degree in geochemistry at the University of Tokyo. Since 1983, she has been a professor at the University of Ottawa, where she teaches courses on mineral deposits and geochemistry. Her ongoing and past research, much of it with nearly 50 past and present students and postdocs, includes element recycling in subduction zones and geochemical and mineralogical studies of porphyry Cu-Au, epithermal Au-Ag, Kuroko base metal, orogenic Au, and unconformity-type U deposits. Keiko is associate editor of several journals, including Economic Geology. She is a fellow of the Royal Society of Canada as well as the Mineralogical Society of America.

Thayer Lindsley Visiting Lecturer


Hartwig E. Frimmel

SEG Fellow

Talk Title

The Global Gold Cycle: How Did it Start?

Hartwig E. Frimmel, who obtained his Ph.D. degree in geology at the University of Vienna, is Professor and Chair of Geodynamics and Geomaterials Research at the University of Würzburg, Germany. He is also associated with the University of Cape Town, where he had previously climbed the academic ladder from lecturer to associate professor. He was leader of the earth science subprogram within the South African National Antarctic Program, member of the Geoscience Scientific Standing Committee of the Scientific Committee on Antarctic Research (SCAR), former president of the Society for Geology Applied to Mineral Deposits (SGA), and director of Lithoscope consultancy. He has served on several editorial boards (including Mineralium Deposita for the past 23 years), on the International Commission on Stratigraphy, as assessor for numerous national research funding and government agencies, and as consultant to mining/exploration companies as well as government bodies. His research interests developed over more than three decades from metamorphic geology and fluid-rock interaction to metallogenesis and economic geology. A special focus has been the study of sediment-hosted base metal and gold deposits, especially those of the Witwatersrand type. His research output includes more than 200 articles and book chapters as well as three books.

Regional Vice President Lecturer


Caroline S. Perring

SEG Fellow

Talk Title

A New Genetic Model for BIF-Hosted Martite-Goethite Ores of the Hamersley Province

Caroline Perring was educated at Cambridge University and the Royal School of Mines but has spent most of her career working in the Archaean Yilgarn craton of Western Australia. She completed a Ph.D. degree at the University of Western Australia in the field of mesothermal Au mineralization before joining the Commonwealth Scientific and Industrial Research Organisation (CSIRO). Apart from a brief stint at James Cook University, working on Fe oxide Cu-Au deposits, she spent the next 25 years studying magmatic Ni-Cu sulfide mineralization and komatiite volcanism, latterly with Western Mining Corporation and then BHP Billiton Nickel West. She is now a principal geologist with BHP's WA Iron Ore division.

Symposium Moderator


Halleluya Ekandjo

SEG Student, iCRAG

Halleluya Ekandjo is a Ph.D. Researcher with iCRAG at University College Dublin, Ireland. Her research work is focused on defining original rock types, alteration types and timing of mineralization and ultimately understand how mineralization and/or alteration relate to stratigraphic and structural framework at the Neoproterozoic Rosh Pinah Zn Pb Ag (Ba+Cu) deposit in Namibia. Halleluya is the current African Representative on the SEG Students Committee.
