TeamWA is a subcommittee of Geoconferences’ Planning and Implementation Committee. It was formed to organise a series of workshops to include at least three presenters who will speak on a common, process-related topic of relevance to the Western Australian geoscientific community, with an aim to drive innovative thinking. The workshops are to facilitate and encourage exploration through cooperation, communication, and by developing partnerships. The speakers for each workshop are drawn from academia, industry and government, in order to illustrate the theory, background, and practical use of current and emerging methods and techniques applicable to driving effective exploration in Western Australia. This will facilitate a direct feedback loop between all facets of the minerals sector.
TeamWA Workshops aim to be half-day programs and held twice a year and where possible, they will include invited high-profile speakers from abroad who can present cutting-edge innovative research or technology. Each workshop will involve presentations by the speakers with ample time to facilitate focused discussions with the audience.

Stephen M. Rowins
Steve Rowins is the Director of the CET and Professor of Mineral Geoscience at UWA. He was
previously the Chief Geologist and Executive Director of the British Columbia Geological Survey and has held academic appointments at the University of British Columbia and the University of Victoria. He has worked for major, mid-tier, and junior resource companies including Vice-President of Exploration of Northern Abitibi Mining Corp., which was named the 2010 Prospector/Explorer of the Year by the Canadian Institute of Mining and Metallurgy (Newfoundland Branch) for the discovery and delineation of the Viking gold deposit. His research interests focus on understanding the genesis of precious and base-metal mineral systems using new concepts and innovative research techniques.
Yongjun Lu is currently the Senior Geochronologist and Isotope Specialist at the GSWA, an Associate Investigator at CCFS, and an Adjunct Senior Research Fellow at the Centre for Exploration Targeting (CET) at UWA. Yongjun’s research interest is primarily in predicting magmatic-hydrothermal mineral deposits by understanding the architecture, fertility and transient geodynamics of a mineral system. He is the recipient of the 2018 Lindgren Award from the Society of Economic Geologists.
Matt Loader is a Postdoctoral Research Associate at the Natural History Museum in London. He holds an MSci from the University of Bristol, and a PhD from Imperial College London. His primary research interest is the evolution of subduction zone magmatism, especially those associated with porphyry Cu deposits, as revealed by rock and mineral chemistry. Matt is the recipient of the 2019 Halstead Award from the Geologists’ Association.
Louise graduated with a PhD from the Australian National University (ANU) in 2018 where she focussed on the experimental partitioning of trace elements between plagioclase, clinopyroxene and melt. Over the past 5 years she has used and operated the laser ablation inductively couple plasma mass spectrometer (LA-ICP-MS) systems at ANU and currently at CSIRO in Perth. With trace element concentrations in minerals her passion and focus, she now is investigating the changes in trace element signatures as possible indicators for magmatic nickel-copper-platinum group element mineralisation as her postdoctoral fellowship at CSIRO.
Paul Agnew is an exploration geologist with more than 30 years of experience with Rio Tinto
Exploration searching for a wide range of commodities in diverse environments. He is currently Chief Geologist – Technical Support and Technology Development, leading a team of technical specialists to deliver innovative exploration technologies to improve the efficiency and effectiveness of mineral exploration.
Presentations are available for some of the past events organised by TeamWA Workshops.
TeamWA workshop: Mapping mineral systems – new perspectives and challenges for exploration geophysics
The Mineral Systems approach attempts to view the spatial and temporal distribution of ore deposits by relating the processes that control the source, transport, and deposition of metals and other commodities to the evolving structure of Earth’s crust and mantle. The change from searching for specific types of mineralisation to understanding aspects of hydrothermal or magmatic architecture at different scales presents new challenges and perspectives for acquiring, processing and interpreting geophysical data.
For this TeamWA workshop we have invited a series of talks by expert geophysicists who address this topic by presenting advances in methods, and case studies.
Innovative approaches to geochemistry for regional scale exploration: tricks and tips
Four speakers will outline their views on how geochemistry can help in a regional scale exploration program. Talks will range from considering regional scale soil geochemistry (David Cohen, University of NSW), hydroceochemical mapping (David Gray, CSIRO), pXRF methods for regional scale targeting (Nigel Brand, Portable XRF Services) and the consideration of geochemical signatures of porphyry-copper (gold) systems (Steve Garwin, Steven Garwin Pty. Ltd).
Read the article Geochemistry for regional-scale exploration: improved methods for improved targeting, written as a forerunner to the event.
Multi-scale seismic exploration for minerals
Seismic is a powerful yet underutilised range of techniques in mineral exploration. Long used in the oil and gas space, seismic is becoming increasingly important in the hunt for hidden mineral deposits, from imagery of regolith through definition of fluid pathways to direct imagery of metalliferous deposits.
