222: The Seismic Approach to Mining Geophysics (Heather Schijns)

Seismic Soundoff

"History is telling us that we're likely to get some new discoveries from introducing seismic into our mixture. Nobody understands mineral deposits like the geoscientists who work on them day in, day out." Dr. Heather Schijns explores the groundbreaking use of hard rock seismic data in mineral exploration with insights from one of the most popular papers at IMAGE 2023. OVERVIEW > The transformative impact of seismic data in identifying deeper mineral deposits and reducing exploration risks > The successful application of advanced processing techniques, like full waveform inversion and Kirchhoff pre-stack depth migration, on the Olympic Dam IOCG deposit > The counterintuitive cost benefits of seismic exploration as mining ventures deeper > The strategic approach to de-risking 3D seismic surveys for business stakeholders > The importance of seismic interpretation in effective mineral exploration and the evolving role of geoscientists in this domain > The potential for seismic methods to enhance safety and reduce high-risk activities in mining Host Andrew Geary and Heather Schijns discuss her expanded abstract, "Sparse 3D seismic survey over the Olympic Dam IOCG deposit." This episode delves into why now is the perfect time for the mining industry to embrace seismic methods, especially as the search for base metal resources deepens and conventional geophysical approaches face limitations. Listeners will be captivated by the journey from a sparse 3D seismic survey to a comprehensive understanding of the Olympic Dam deposit and how this approach paves the way for future exploration strategies. The episode also tackles the critical business aspect of seismic exploration, urging listeners to consider the value and risk reduction seismic data can provide.
