Summary
A range of presentations and demonstrations explore 3D geological modelling in this workshop format event. Hosted at the beautiful University of Notre Dame Walyalup (Fremantle) as part of the 6th International Archean Symposium, attendees will be led through a range of topics around 3D geological modelling, including data selection, curation, visualisation, and collaboration. Features of the open source ‘Loop’ 3D modelling platform will be described alongside case studies from complex geological regions. The ‘Noddyverse’ helps examine the range of plausible 3D models, while geophysical modelling is made possible through the open-source Tomofast platform. Various spatially aware data science methods with be presented. The afternoon sessions of this two-day event are dedicated to hands-on demonstrations and discussion. You will need to bring your own device with access to a Windows operating system

Summary
This workshop is a companion event to the associated fieldtrip (FT3) that will examine drill cores
relevant to understanding the Archean-Proterozoic transition within the Mount Bruce Supergroup,
and showcase the facilities of the GSWA core library. Some of the key drill cores that will be on
display include the TCDP cores from the Turee Creek Group, part of ABDP9 from the Hamersley
Group, and a selection of other important Mount Bruce Supergroup cores. If FT3 is cancelled for any
reason, this workshop will be re-purposed as a combined core workshop and virtual fieldtrip.
Maximum number of people: 35, with preference given to FT3 participants.

The aim of the course is to give you the fundamental tools and knowledge to improve your
geological logging by incorporating geochemical and mineralogical data.
This one-day course features a mixture of theory and tutorials and will cover (1) incorporating
geochemistry into geological logging, (2) spectral mineralogy for drill core using HyLogger-3 data and
(3) multiscale analysis and domaining of drill hole data. The course will feature several data analysis
tools including TSG (The Spectral Geologist), ioGas and Data Mosaic (multivariate wavelet
tessellation).
Maximum number of people: 18
Part 1
Nick will demonstrate how to use geochemical data derived from drilling samples to enhance your
geological logging. He will discuss how to use simple tools from ioGas and Excel to summarise and
visualise your data. Nick has vast experience from logging core all around the world and will provide
you with practical tips to speed up your logging and describe how to focus on the key elements
critical for understanding your mineralising system.
Part 2
June will show you how to automatically domain your drill hole into litho-geochemical rock units
using your geochemical data. She will give an overview of the theory behind the method for
multiscale analysis (wavelet tessellation) and introduce you to the Data Mosaic web app. You will be
guided through a tutorial using this software to automatically generate litho-geochemical logs at any
scale.
Part 3
Jess will give you a practical introduction to spectral mineralogy using data from the HyLogger-3. She
will demonstrate the use of The Spectral Geologist (TSG) software for visualizing and investigating
drill core spectral data and extracting spectral mineralogy. She will also show you how to access and
download public spectral data sets from Australia’s National Virtual Core Library (NVCL), which is the
world’s largest drill core mineralogical database.
Part 4
June and Jess will guide you through a tutorial to apply Data Mosaic to simplified spectral
mineralogy, which will help you to accurately log rock units and alteration styles.
Laptop:
Please bring a laptop so you can participate in the tutorials. Temporary TSG and Data Mosaic
licences will be provided to all participants.

Hydrogeochemistry has become a tool of interest in regional mineral exploration in Australia for
various commodities. CSIRO’s Discovery Program has developed a practical workflow for mineral
explorers which goes all the way from sample collection, field data capture (FAIMS mobile app),
sample analyses, data handling (QA/QC), and data interpretation and integration. CSIRO has also
developed a number of indices and element ratios for mineral exploration using hydrogeochemical
data which are able to highlight regions of known and potential mineralisation across Australia. We
now have a new tool XT Hydro TM to make the processing of these indices easier than ever
before. A process which was previously time consuming for researchers is now producing faster, and
more consistent results. This has also led to the compilation of a continental-scale hydrogeochemical
database which provides baselines for many elements/parameters which can be used to put site
data into perspective.
This workshop aims to introduce you to the why of hydrogeochemistry:

If you’re working in any greenfields mineral exploration in Australia you’re almost guaranteed of
having to work with, through and around the blanket of regolith that hosts, guides, or hinders
exploration. This course is designed to give those less familiar with working in regolith an
understanding of landscape settings and formation as well as several different geochemical methods
that are available to use in these environments. The course will focus on practical applications,
limitations and key considerations when using various geochemical methods. Finally, we will
highlight the value of using geochemical results in landscape context as well as a few case studies
where different approaches have been used.
Maximum number of people: 30
Part 1: Regolith terms/landscapes/formation/weathering
Part 2: Exploration sample media (soils/lag/plants/groundwater/mineral phases)
Part 3: Analysis options – instruments and what to expect from the laboratories (what they do and
what are the limitations/handheld devices included, a note on QAQC)
Part 4: Analysis options – chemical extractions (what and why of partial and total digestions as well
as size fractions and other considerations)
Part 5: Putting results in context (using the DSO – digital sample observer from UltraFine® Next Gen
Analytics as an example of how to do this, but will also provide alternative options for other
approaches)
Part 6: Case studies (different commodities, areas and approaches as well as the value of
understanding metal migration mechanisms)
Requirements / Laptop: None, just an interest in regolith
