Tom Benson

Tom Benson serves as Vice President of Global Exploration at Lithium Argentina (TSX: LAC), where he leads the company's worldwide search for new lithium resources. He brings an unusual combination of deep academic geology and hands-on industry exploration to one of the battery metals sector's most closely watched companies. For investors trying to understand where future lithium supply will come from — and which projects are geologically real — Benson's perspective is grounded in direct fieldwork.

Benson's academic foundation is in physical volcanology. His Ph.D. and master's research at the University of Nevada focused on the caldera systems (large volcanic depressions formed by collapsed magma chambers) associated with the Yellowstone hotspot, work he conducted across Nevada and Oregon. That expertise in volcanic geology translates directly to lithium brine exploration, since many of the world's highest-grade lithium deposits form in basins linked to past or active volcanic activity. His research on what he terms "energy-critical elements" — materials essential to modern energy technologies — has been cited in outlets including the Smithsonian Magazine, which featured his work on the connection between supervolcanoes and lithium deposits.

At Lithium Argentina, Benson applies that geological framework to the company's portfolio of South American brine projects in Argentina's Lithium Triangle, as well as past involvement with U.S. projects. His approach centers on understanding the subsurface hydrology and geochemistry of salars (salt flats where lithium-rich brine accumulates) to identify zones with the highest grades and most efficient extraction potential. Rather than relying on surface sampling alone, his work emphasizes the deep geological structures that control brine flow and concentration — the difference between a deposit that looks promising and one that can be produced economically.

Investors following lithium should pay attention to Benson's commentary because he bridges the gap between technical geology and commercial development. His public remarks have emphasized that lithium demand is still in early stages of a multi-decade growth cycle, driven by electric vehicle adoption and grid-scale energy storage. When he speaks about specific projects or regions — including his work defining what he calls "the African lithium frontier" — he brings an explorer's eye to which geological settings are most likely to host economically viable deposits.
