Courses
and Workshops
Courses and workshops are provided both prior to the IGES and immediately following the main Symposium sessions. Each will follow a set theme and include course notes. We have concentrated on assembling teams of presenters, to give you as broad a view of the subject as possible. The courses will be less formal than the main Symposium sessions and questions and discussion are encouraged. Some will follow a course format; others will contain course work but involve the attendees to varying extents in a workshop environment. There might be minor changes to the teams, but the basic course themes will be as below.

1.1
Mineral exploration using groundwater geochemistry
17th
September 2005
Presenters: Patrice
de Caritat, David Gray,
Michelle Carey and ‘Bear’ McPhail
Course registration A$253
This short course will have only the necessary formal theoretical lectures and will focus on a number of mineral exploration case studies. With each case study, relevant theory will be reviewed and applied to solve real exploration issues. The presenters will draw from their experience and may call on invited guests for other studies.
Contents:
Introduction:
Review of fundamental principles
Methods:
How to collect groundwater
Au
exploration in the Yilgarn and Gawler cratons: pH, redox, salinity
Au
exploration at St Ives: Hydrogeology, salinity
Pb-Zn
exploration in the Curnamona Province: Oxidation, isotopes, adsorption
Ni
exploration at Harmony: Oxidation, water-rock interaction
Others as time permits
1.2
Interpreting Geochemical Data
17-18th
September 2005
Presenters:
Mark
Arundell, Simon Gatehouse, Paul Agnew, Dave Lawie and Mike Whitbread
Course registration A$495
Multi-element
geochemistry is now common practice in mineral exploration. Masses of data are
generated but commonly not fully utilised by project geoscientists.
Anomaly definition has tended to focus on the highest numbers in selected
target elements. However, in many circumstances, the highest numbers may not
be the most significant in a particular geological context.
This course will focus on more informative techniques of interpreting and
visualising geochemical data. This
style of targeting focuses on placing all of the geochemical data into a richer
geological context and working with the natural multi-element geochemical
associations which can be identified in most geochemical data sets.
The techniques will be demonstrated with surficial and drillhole data
sourced from around the world. This
hands-on course will be directed at geologists and geochemists of all levels of
experience involved in mineral exploration, academia or government research.
How
to look at data, basic data analysis, leveling of historic data
Drainage,
soil, rock, lag, and drill samples. Interpretation
of data for each are illustrated with case histories.
Local
scale variation, advanced data analysis, zonation
Signature-based
interpretation, factor analysis, additive indices, multi-element data
visualisation
Robust
variants of principal component analysis, discriminant analysis, regression.
Interpreting
partial leach data
Lithogeochemistry for rocktype identification and quantifying metasomatic effects.
1.3
Regolith Mapping
17-18th
September 2005
Presenters:
Mike
Craig, Ravi Anand,
Bob Gozzard and Tom Cudahy
Course registration A$396
Regolith materials, regolith geology, landscapes and regolith mapping will be demonstrated with lectures and practical exercises using regional-, district- and local-scale regolith investigations. Presenters will draw from available case histories and their experience. Remotely sensed imagery, geophysical and topographic data will be used to map the broad and specific distribution of the regolith. Gathering, collating, storing, retrieving and working with regolith data in a modern digital GIS environment requires organisation. This is an important learning component throughout the workshop. Exercises will strengthen, test and extend the regolith knowledge of the participants.
Philosophies
of regolith geology and regolith mapping;
Significant
issues linking regolith and exploration environment
Mechanics
of map-making - strengths and weaknesses, GIS, multi-data sets, and analysis

the rules for regolith mapping are not the same as they are for traditional
geology maps
What
regolith maps can and cannot tell you
Getting
the exploration advantage from a regolith map
‘Hands-on’ regolith mapping exercise.
1.4
Application of Geochemistry to Mine Closure
18th
September 2005
Presenters:
Rob
Bowell, John Chapman, Dick Glanzman, Ron Watkins and Jeff Parshley
Course
registration A$253
This course will address geochemical aspects of mine closure. The presenters will use examples from their own experience and of others to discuss waste rock, tailings, remnants of heap leach processes, pits, pit lakes and ways in which water quality can be improved by natural processes.

Managing your data – Every bit counts
Date:
24th September 2005
Presenters:
Craig
Morley, Rob Freeth, Andrew Dent, Bill Withers and Richard Carver
Course Registration A$253
Poor information can break a company and good information can make a company rich. So why is information management still an issue? At this one-day workshop, participants will work with the experts to identify geochemical data management issues and critical success factors. Participants will come away with a ‘best practice’ geochemical data management template, an understanding of how this could be integrated into their business and a look into the future of data management.
An
understanding of the consequences of getting geochemical data management
right and the pitfalls of getting it wrong.
A
list of the three most important geochemical data management issues for the
next 5 years.
A
‘best practice’ strategy for dealing with these issues.
A list of strategic and critical factors that are needed to ensure best practice.
