Product description:

As part of the Victorian Government’s Gold Undercover Initiative the Department of Primary Industries (DPI) contracted Geotech Airborne Pty Ltd (Geotech) to acquire Helicopter-borne Versatile Time Domain Electromagnetic System (VTEM) data along four traverses that are coincident with a deep seismic reflection profile that DPI recorded in June 2006.

A total of 381 line kilometres of VTEM data were collected in April 2008. The survey was supervised by DPI and Robert Smith of Greenfields Geophysics.

The aims of the survey were to:

  • Map and characterise the conductivity responses in different geological settings of northern Victoria
  • Determine the depth to basement
  • Map and characterise the conductivity response of possible saline ground waters
  • Determine the suitability (e.g., depth penetration) of the VTEM system for use in Victoria.
