Liquid Integrity System (LIS) have been developing methods for detection of defects in liquid storage sites since being founded in 2012. These sites have varied from potable drinking water sites to acid tailings and everything in between. Drawing on a background in electrical geophysics and a desire to improve leak detection while minimising impact to the client’s operations, LIS has developed equipment for monitoring and surveying a wide variety of sites. Our biggest challenge over these years (like many tech-based business) has been ongoing development and adaption – our clients continuously push us to expand into new detection scenarios. In this talk we will discuss the range of techniques that we have developed, and describe some of the varied settings that we have worked in. There is a lot to talk about and lots of stories that we think most field geophysicists can relate to.

Magnetotellurics: Practical Survey Design and Model Assessment

Monday, May 6, 2024

Workshop Overview:
Gain an understanding of the magnetotelluric (MT) method, including survey design, model resolution, and the pros and cons of different modelling approaches. Learn how to identify and assess key indicators of data and model quality. The workshop is structured around a synthetic MT dataset over a hypothetical porphyry deposit. By interactively working through the data, participants will see the impact of different choices they make about survey design, station spacing and 1D, 2D or 3D modelling on the final results.
Participants will leave the workshop equipped to understand the strengths and limitations of their MT models and to interact more knowledgeably with MT contractors and consultants.

Who should attend:
The workshop is designed for anyone who commissions or works with MT data and models in the exploration workflow, including:

  • Geophysicists who work with MT data and models but may not produce the models themselves
  • Geologists or other geoscientists who use MT models in their exploration strategy

No existing expertise in MT, mathematics or geophysics is required, but a willingness to work through geophysical data and concepts is assumed. The workshop is interactive and participants will analyse provided data but no special software is needed.

Learning Objectives:

  • Conceptually understand the MT method, including how different Earth structures affect MT data
  • Learn key QA/QC criteria to assess MT data and models
  • Observe the impact of dimensionality and strike on MT model reliability
  • Compare resolution of features in 1D probabilistic models, 2D models and 3D models and with different survey designs.

Workshop Facilitator:
The workshop is presented by Dr Kate Selway of Vox Geophysics. Kate is internationally recognised as an expert in MT and spent more than 15 years working in university research and teaching positions, including at the University of Adelaide, Yale, Columbia University, the University of Oslo and Macquarie University. She has modelled and published on MT data she has collected from Australia, East Africa, North America, Greenland and Antarctica. In 2022, Kate founded Vox Geophysics with a goal of helping mineral explorers to maximise the value gained from their MT data.

Date and Time: Monday May 6th, 9:00 am to 5:00 pm
Location: In.Studio, 268 Pirie St, Adelaide
Cost: $950 or $850 for ASEG members, GST inclusive.
Numbers limited to 16 people.

NSW Tech night: Advanced geomodelling to reveal buried deposits

Wednesday, April 24, 2024

Title: Advanced geomodelling to reveal buried deposits

Presenter: Addison Tu

Date and time: Wednesday, 24th April 2024 at 1800 (NSW)



Porphyry deposits are of important societal significance as critical sources of copper. 

Copper demands are projected to increase significantly to supply the transition to net-zero, but discoveries have dwindled in recent decades. The finite number of deposits exposed at the surface are nearing depletion, and advancements to exploration techniques must target buried deposits. Here we present a workflow which incorporates machine learning predictions for deposit formation within the crust, with a highly calibrated landscape evolution model to track the vertical motion of deposits through geological time. The results inform where deposits may be preserved and at what depth, or where deposits have been destroyed by erosion. We tested this approach on the mountains of New Guinea, which feature abundant volcanism responsible for deposit formation at depth and extreme erosion to exhume deposits toward the surface. Our approach identified high prospectivity in accordance with the spatial extents of known surface deposits, identified several highly prospective regions for near-surface deposits and where deposits have been destroyed by erosion. Our workflow provides a region-scale prospecting tool to de-risk the economic and environmental cost of field-based exploration. Importantly, the workflow is open-source, scalable to other regions and even adaptable to other mineral systems (with constraints on the depth of formation


Addison is a PhD student and Research Assistant within the Earthbyte group, working closely with Dr. Sabin Zahirovic and Dr. Tristan Salles. His research focuses on Eastern Australia, particularly concerning the eastward accretion of microcontinents and volcanic arc-islands since the Cambrian. Geological events in this region and period involve the formation of mountains and the closing of seaways, with many implications for climate, past landscapes and environments, and the formation and preservation of economic deposits.

Addison utilises landscape evolution modelling, tectonic models, and thermochronology with a focus on linking Earth’s surface processes and evolution to other Earth Systems such as the tectonics, climate and the ocean. He also has experience developing landscape evolution models and landform design tools within industry.


WA Tech Night: DAS Reflection Seismic For Mineral Exploration in Harsh Environments

Thursday, May 2, 2024

Title: DAS Reflection Seismic For Mineral Exploration in Harsh Environments

Presenter: Prof Milovan Urosevic

Date and Time: Thursday, May 2 · 1730 AWST



A number of hyper-saline lakes across Western Australia are known to overlie substantial and diverse mineral resources. Exploring those by means of the application of conventional equipment is limited and prone to significant hardware issues and equipment damage. In contrast such an environment seems appropriate for the application of the DAS technology. This technology originated in the 1980s and its practical potential in seismic sensing was developed in the 1990s, as described in the historical review of Hartog (2018). Distributed Acoustic Sensing (DAS) uses strain-induced optical distortion effects to re-purpose optical telecommunication fibres as multi-channel seismic arrays. In this study, we present the evaluation and application of DAS for seismic exploration of mineral resources over the years, through several field studies. We show that DAS has the potential to replace surface geophones in such environment. Further test were oriented towards implementation of a reflection mode DAS in a dry hard ground surface as typically found in mineral exploration. To implement DAS in the reflection mode we have developed automated DAS underground installation using a plough attached to a variety of different utility vehicles. The key aspects of the new super-effective 3D seismic exploration with DAS technology are discussed in our presentation. The results of 3D DAS seismic experiment is giving us confidence that implementation of DAS for mineral exploration has a bright future.


Milovan Urosevic received a BSc (Hons) in geophysics from the University of Belgrade in 1980, an MSc in geophysics from the University of Houston in 1985 and a PhD in geophysics from Curtin University in 2000. He held leading roles in several major Australian cooperative research centres such as APCRC, CO2CRC, DETCRC, and MinEx CRC. His main interest is utilising new seismic technologies to advance the exploration of natural resources. Milovan is an Emeritus professor at Curtin University, Perth, WA and co-founder of HiSeis, a world-leading hard rock seismic company. He is a member of ASEG, EAGE and AGES.
