Vox aims to support mineral explorers by providing robust geophysical models and integrated interpretations

Geophysical excellence
Reliable geophysical models are necessary for exploration, especially as exploration moves further under cover.
Vox are subject matter experts in magnetotellurics (MT). Vox chief geophysicist and managing director, Dr Kate Selway, gained a PhD working with MT data in 2006. Until founding Vox in 2022, Kate worked with MT as a university researcher and lecturer, including at the University of Adelaide, Yale, Lamont-Doherty Earth Observatory (Columbia University), the University of Oslo, Macquarie University and the University of South Australia, and is currently an Adjunct Associate Professor at the University of Tasmania. Kate is frequently invited to speak and write review papers on the MT method, including by the American Geophysical Union, the International Union of Geodesy and Geophysics, and prestigious journals including the Nature group.
MT data have become increasingly important in exploration over the last two decades, especially as targets have moved deeper under cover. However, MT data are often not straightforward and require careful, expert treatment. Vox have this expertise to help explorers plan their MT surveys and understand their data. Vox can provide explorers with tested, robust and reliable inversions of MT data from prospect-scale to lithospheric-scale, providing confidence on subsurface structure.
Integrated interpretations
Exploration requires every scrap of data to be understood, taken advantage of, and integrated.
Vox are passionate about helping explorers make the most out of their geophysical data. By integrating geophysical, petrophysical, geological and geochemical data, Vox have the skills to produce meaningful, integrated interpretations. Our goal is to help explorers move beyond using their geophysical data to simply target anomalies. Instead, we can help explorers understand what their geophysical data are telling them about the composition and structure of the subsurface and to identify regions where geological processes may have led to mineralisation.
Dr Kate Selway has a proven track record in integrating geophysical and geological data to interpret Earth composition. As a researcher, Kate, with her students and postdocs, has shown how kimberlite magmatism relates to geochemical and MT anomalies, combined seismic and MT data to constrain mantle viscosity, developed open-source software to produce compositional interpretations of mantle MT data, interpreted MT models of active subduction zones in terms of melting and metamorphic reactions, among many other advances. Kate is excited to use these skills to help explorers understand their prospects and to work with them to develop mineral systems models that fully integrate their geological and geophysical data.
