Candidate for President-Elect (2025)

Alan J. Wilson

(Joined in 1995; Fellow since 2001)

Vote

I was born and raised in Glasgow, Scotland, where my interest in geology stemmed from a love of the Scottish outdoors and a family holiday to Italy as a teenager that included a visit to Pompeii and a trip to the top of the offending active volcano, Vesuvius. A B.Sc. Honors degree in geology (Edinburgh University, 1990) sparked an interest in ore deposits, resulting in an M.Sc. in mineral exploration and mining geology (University of Leicester, 1991). Upon graduation, I was fortunate to get a job with Rio Tinto as an exploration geologist—first based in Quito, Ecuador, then La Paz, Bolivia—exploring the northern and central Andes for porphyry copper, epithermal gold-silver, polymetallic volcanic-hosted massive sulfide (VHMS), and porphyry tin deposits. Highlights of the six years spent with Rio included the many field-based training opportunities and mine visits to copper and gold deposits of the western United States to learn what an ore deposit looks like. Fueled by a desire to live at lower altitude, I relocated to Peru in 1997, where I continued to develop expertise in porphyry, epithermal, and iron oxide copper-gold (IOCG) exploration with Rennison Goldfields and Billiton throughout the Peruvian Andes.

A series of fortuitous events led to a move to Tasmania, Australia, in 2000, where I undertook the first Ph.D. on the then-recently discovered alkalic gold-copper porphyry deposits of Newcrest Mining Ltd. Sponsored by Newcrest’s exploration group at Cadia, this applied field- and lab-based research project fueled an ongoing interest in understanding the geology, genesis, and exploration context of the full range of porphyry copper deposit types, not just the calc-alkaline giants of the Andes. Upon graduation in 2003, Newcrest hired me, where I co-led district and regional exploration around the Telfer intrusion-related gold-copper deposit in the Great Sandy Desert of Western Australia. However, the desire to roam was still strong, and in 2006 I joined the exploration team at Anglo American—first based in Perth, Australia, and then Santiago, Chile—as Copper Commodity Leader, where I was responsible for all technical and research aspects of Anglo’s global copper exploration program. This opportunity expanded my copper expertise into sediment-hosted copper deposits of the Central African Copperbelt and the Kupferschiefer in addition to porphyry-epithermal systems in the southwest Pacific and Tibet; IOCG deposits in the Carajás of Brazil; and porphyry deposits from northern Colombia to central Argentina.

In 2010, a new opportunity arose to join Antofagasta Minerals’ exploration team and lead a rapidly growing team of experienced explorers building a portfolio of early to advanced-stage copper exploration projects globally. In a nine-year tenure with Antofagasta, which involved stints living in Santiago, Brisbane, and Toronto, countless exploration- to development-stage projects were reviewed globally and over 70 commercial exploration agreements consummated, though sadly no economic discoveries or acquisitions were made. Building on nearly thirty years of field-based experience, in 2019, I chose to become an independent consulting geologist, relocating with my wife to her longtime family home base in Anguilla, British West Indies, where we established a consulting company offering services to the mineral exploration and water management sectors. Since then, I have consulted for over 40 mining and mineral exploration companies globally, focused mainly on geologic aspects of copper exploration projects as well as target generation and strategic and commercial aspects of the business.

I have been an active member of the SEG since 1995, and a Fellow since 2001. I have served on numerous committees (Distinguished Lecturer, Lindgren Award, Nominating, Awards), as a Councilor from 2019 to 2021, as the SEG International Exchange Lecturer for 2018, and on the field trips committee for the SEG 2022 Conference in Denver. I have published and coauthored several papers in Economic Geology and other peer-reviewed journals and actively review submissions to Economic Geology on an as-needed basis.

Candidate for Councilor (2025-2027)

Rowena C. Duckworth

(Joined in 1995; Fellow since 2013)

Vote

Rowena obtained a Ph.D. in economic geology from the University of Cardiff, and her doctoral research focused on a deformed volcanogenic massive sulfide (VMS)-style deposit in northern Sweden, which laid the foundation for her subsequent career. After completing her Ph.D., she was fortunate to be awarded a place on Ocean Drilling Project (ODP) Leg 139, which drilled sea-floor sulfide deposits in the Middle Valley off Juan de Fuca Ridge. This experience led to a three-year Natural Environment Research Council (NERC)-funded postdoctoral fellowship based in Cardiff.

Rowena then made the move to Townsville, Australia, where she joined James Cook University (JCU) as Associate Director of the Australian office of the ODP. This involved sailing on a second ODP cruise, Leg 169, which undertook groundbreaking drilling through the stratigraphy of a recently formed and actively smoking sediment-hosted Cu-Zn-Pb deposit.

Rowena then spent several years on postdoctoral research at JCU, focusing on deposits in North Queensland, notably in the Mount Isa and Cloncurry districts. During this period, she also played a central role in leading the Economic Geology Research Unit (EGRU).

In 2012, Rowena established her own petrography business, which she has managed alongside part-time roles in the exploration industry and the geologic service sector. These have included recruitment and mining analyst roles in addition to technical analytical positions, giving her a well-rounded knowledge of the industry.

She now has over three decades of postdoctoral experience in the exploration and mining sector, with a wealth of expertise at the microscale. In her consulting capacity, she has been fortunate to work on a large array of mineral systems, including volcanic and sediment-hosted massive sulfides, skarns, epithermal and porphyry deposits, iron oxide copper-gold (IOCG) deposits, intrusion-related gold (IRG) systems, lithium pegmatites, and rare earth element (REE)-carbonatites.

Throughout her career, she has been an active contributor to the field, presenting research findings at more than 30 conferences and publishing in peer-reviewed journals. Additionally, she has been involved in various committees within the SEG (Student Grant Committee, Distinguished Lecturer Committee, Nominating Committee, SEG 2022 Conference Committee), as well as serving on local committees for the AIG (Australian Institute of Geologists), the AusIMM, and the Australian National Rock Garden steering committee.

Mentoring emerging geoscientists holds special significance for Rowena. She played a key role in the development of AIG's mentoring program and remains dedicated to guiding younger geologists as they navigate their careers.

Lynette N. Greyling

(Joined in 2002; Lindgren Fellow since 2006)

Vote

Lynnette’s interest in economic geology started with an M.Sc. study on Mississippi Valley-type Pb-Zn deposits in South Africa. She obtained a Ph.D. from the University of the Witwatersrand characterizing the hydrothermal fluids of the Zambian Copperbelt. She joined the SEG as a student member and was involved in the first South African SEG student chapter, based in Johannesburg. She worked as a consulting geologist on platinum and gold in South Africa before joining Randgold Resources as an exploration geologist, first in Tanzania and then in West Africa. During this time, she worked on Archaean and Palaeoproterozoic orogenic gold deposits and gained valuable experience in greenfields, brownfields, and feasibility exploration phases.

She is interested in how structures create pathways and traps for hydrothermal fluids, leading to precious and base metal mineralization. This was the focus of her subsequent postdoctoral research on Birimian-hosted orogenic gold deposits in northern Cote d’Ivoire, using fluid inclusions and stable isotope geochemistry. This research was based at the Department of Geological Sciences at the University of Cape Town in South Africa, where she became a lecturer in economic geology. During this time, she supervised several postgraduate students and contributed to establishing the second South African SEG student chapter, based in the Western Cape.

She has contributed to several of the SEG’s workshops on orogenic gold deposits, hosted annually prior to the African Mining Indaba in Cape Town. She is a Fellow of the SEG, the Geological Society of London, and the Geological Society of South Africa, and past Regional Vice President of Sub-Sahara Africa for the SGA. She was Vice President of Exploration for Goldrange Resources, with projects in Cote d’Ivoire and Tanzania. She is currently based in the UK and works as an independent consultant.
