Vectoring within Central Victorian Gold Alteration Haloes Using Geochemical and Mineralogical Data

This 1-day workshop would involve a review of publicly available geochemical and mineralogical data from representative central Victorian gold deposits, including Bendigo, Ballarat, Fosterville, Castlemaine, Costerfield, Maldon and Wildwood. 

About this event

Emphasis will be placed on the identification of alteration zones surrounding the deposits and key geochemical and mineralogical indicators that can provide an indication of direction and distance towards mineralised structures.

Participants will need to bring a laptop computer with them and download a trial version of ioGAS geochemical assessment software immediately before the workshop (trial version is time-limited and restricted to one installation per computer).

A series of presentations introducing concepts and data sets will be interspersed with hands-on interpretation of integrated drill hole and surface rock chip data sets containing geochemical and mineralogical (quantitative XRD, hyperspectral, field staining) data from various central Victorian goldfields. A brief introduction to exploratory data analysis (EDA) using ioGAS will be provided.

Dr Dennis Arne, Geochemist & Director, Telemark Geosciences
Dennis has more than 35 years experience in geology and applied geochemistry globally with a particular emphasis on gold. He is currently working as an independent consulting geochemist under the banner of Telemark Geosciences and is an Associate Principal Consultant with CSA Global.

He has overseen major regional geochemical exploration programs for gold in the Yukon and Nunavut in Canada, eastern Victoria, Suriname, Sudan and Laos. He was Director and Principal Consultant – Geochemistry of CSA Global Canada until 2017, General Manager and Principal Consultant – Geochemistry for Revelation Geoscience (now CSA Global Canada), Principal Consulting Geochemist with ioGlobal (now Reflex Geochemistry) and formerly Senior Geochemist with Geoscience Victoria. In the latter positions, he undertook an extensive lithogeochemical investigation of central Victorian gold deposits, undertook soil geochemical investigations over the Lockington gold discovery beneath the Murray Basin sediments, re-interpreted surface geochemical data from the Bendigo and adjacent maps sheets, and compiled hydrogeochemical gold data from CSIRO in Victoria.

He is a member of the Australian Institute of Geoscientists, a Fellow and Vice President of the Association of Applied Geochemists, is a Registered Professional Geoscientist (Geochemistry) in Australia and a registered Professional Geoscientist in British Columbia.
