Geology of GOLD course – March 2020

 

Date

9-13 March 2020


 

Venue

School of Earth Sciences, University of Melbourne


 

A 5-day course of lectures, practical sessions and a 2-day field trip devoted to the Geology of Gold.

COURSE COORDINATOR: Prof David Phillips

PRESENTERS INCLUDE:
Prof Neil Phillips, Dr Andy Tomkins, Dr Rod Boucher and Prof David Phillips.

 
It is suitable for geologists in the global minerals industry or government with early exploration or mining experience who want a broad coverage of the gold geology as well as some of the latest research ideas and how they apply to mineral exploration.

The course covers all major types of gold deposits with emphasis on greenstone-hosted and sediment-hosted orogenic gold deposits. Other gold deposits covered include epithermal, Carlin and Witwatersrand gold deposits. The field trip takes participants through the heart of the Victorian gold province with a visit to Fosterville gold mine and an industry meeting in Bendigo.

Several important ideas used in the industry today have been pioneered in earlier presentations of the GOLD course. Come and find out why gold deposits are unlikely to form at 8000C, why Witwatersrand production is plummeting, the links between magmatic processes and gold, the exploration methods used in Australia to discover 550 million ounces of gold since 1979, why Fosterville is described as the best gold deposit in Australia at present, and what the recent nuggets and alluvial gold discoveries in the Pilbara mean.

The course covers the deep weathering in the Carlin Gold Province which is over 1000 feet deep in places. We discuss the importance of understanding and then removing the effects of this weathering before sampling, analysis and attempting to determine how these important gold deposits formed. New insights here open new exploration opportunities globally.

Third from the left in the photo gallery we have a visitor thanks to the Somerville Collection in Bathurst NSW. This is mostly pyrite retaining the beautiful detail of a Mesozoic ammonite; and geologists generally agree that this is a normal shelly ammonite replaced by pyrite some time after death and burial.

Far right of the photo gallery are our regular Fe-oxide pisoliths (left) from the modern land surface at Klerksdorp, South Africa. The right side shows pyrite nodules from the Archean Witwatersrand gold reefs approximately 3 km below the surface. It is widely considered impossible for there to have been Fe-oxide pisoliths in Witwatersrand reefs that were replaced by pyrite.


 

Cost for industry participants

AUD $1000, including the 2-day field trip. Numbers will be limited due to the field component, and registrations are likely to close early
