ASEG Webinar: Passive Seismic - Applications of Ambient Noise Interferometry for Mineral Exploration

Branch: TAS Title: Passive Seismic - Applications of Ambient Noise Interferometry for Mineral Exploration Presenter: Dr Richard Lynch, Sisprobe Date and Time: Thursday 26 August 2021 at 1800 AEST Abstract: As mineral exploration seeks deeper targets under cover, the need for low cost and low impact subsurface imaging is increasingly important. A recent addition to the toolbox of geophysical methods is ambient noise surface wave tomography (ANSWT) which produces an S-wave velocity image of the subsurface using naturally occurring seismic signals ("noise") from waves, earthquakes, traffic, etc. - no active controlled seismic sources required. In this presentation, I will provide an introduction to the ANSWT method and show how it is applied for early-stage mineral exploration using some recent projects in Canada, South Africa and Australia. Bio: Richard Lynch has 20 years experience in the global mining industry focused on all aspects of mine microseismic monitoring. From 2011-2017, he served as CEO of IMS, a leading mine seismology company. Richard is currently the COO and directeur général of Sisprobe, a French company that is the world leader in ambient noise passive seismic imaging and monitoring for industrial applications, including hard rock mineral exploration and real-time TSF monitoring. Richard has a PhD in theoretical physics from Wits University in South Africa. He currently lives in Hobart.
