Archean-Proterozoic boundary core workshop

Date

Friday 28th July 2023

Location

GSWA Perth Core Library, Carlisle.

Cost: $50

The workshop is sponsored by GSWA and will include morning and afternoon tea and a light
lunch (please advise dietary requirements at registration).

Presented by

Dr. David Martin, GSWA

Dr. Heather Howard, GSWA

Enquiries

David.Martin@DMIRS.wa.gov.au

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.


Target 2023 Workshops

 

Improve your geological logging with geochemical and hyperspectral data

Date

Monday 24 th July 2023

Location

CSIRO, 26 Dick Perry Ave, Kensington, WA.

Cost

$250

Presented by:

Dr. June Hill, CSIRO Mineral Resources,

Dr Nick Oliver, HCOV Global

Dr Jess Stromberg, CSIRO Mineral Resources

Enquiries

June.Hill@CSIRO.au

Summary

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

Sessions

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.


A practical guide to exploration hydrogeochemistry

Date

Monday 24th July 2023

Location

CSIRO, 26 Dick Perry Ave, Kensington, WA.

Cost

$250

Presented by

Dr. Nathan Reid, CSIRO Mineral Resources

Alex Hunt, CSIRO Mineral Resources

Summary

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:

  • What can it tell you about geology under cover, its strengths and weaknesses
  • Targeting mineral systems at regional and camp scales
  • How to collect consistent samples and the tools we can provide
  • What laboratory analyses are required and at what detection limits
  • How to check your data (QA/QC)
  • How to process data with XTHydro TM
  • How to interpret your data within the regional context and tips for targeting

Maximum number of people: 22

Part 1: Collection
  • Overview of use cases for Hydrogeochemistry in mineral exploration
  • Collecting samples in the field for hydrogeochemistry including data capture and integrity e.g. FAIMS
  • Laboratory processing and analyses
Part 2: Data treatment
  • QA/QC
  • XT Hydro TM
  • GWB
  • ioGAS
Part 3: Interpretation
  • Interpreting the results
  • Detecting weathering sulfides
  • Detecting known mineral systems
  • Greenfields exploration
  • Tenement selection
  • Near misses
  • Continental scale data

Requirements / Laptop

Laptop with Excel. Desirable, but not essential: ioGAS and the Geochemists Workbench


Regolith Geochemistry for Minerals Exploration

Date

Monday 24th July 2023

Location

CSIRO, 26 Dick Perry Ave, Kensington, WA.

Cost

$250

Presented by

Dr. Ryan Noble, CSIRO Mineral Resources

Dr. Walid Salama, CSIRO Mineral Resources

Summary

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

Sessions (approximately 1 hour each)

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
