Exploration Geochemistry Seminar – 3rd December 2018

Answers to questions you have always wanted to ask, or should ask



Monday 3rd December 2018
8.00am – Registrations; 8.25am – Seminar Introduction commences
4.55pm – End of seminar followed by Drinks



Burswood on Swan
1 Camfield Drive, Burswood WA 6100


The AIG WA Branch is holding a one day seminar to answer some of the questions you may have always wanted to ask such as: why do we sample that size fraction; or why do people still talk about mesh sizes; or which analytical methods to use for what?

The seminar presentations from industry will be inspiring for geoscientists involved in
exploration geochemistry and will cover several aspects of geochemistry including:

  • geochemistry essentials,
  • planning a program,
  • doing the field work,
  • analytical techniques, both field and laboratory,
  • interpreting the results, and much more.
