Mineral Exploration with Airborne Geophysics

Airborne geophysical data can provide valuable input in mineral exploration for identification of likely drill targets but acquiring geophysical data can be an expensive exercise. It is vitally important to retrieve as much information as possible from the data to enhance the likelihood of exploration success.  This century has witnessed the influence of knowledge to shape economies and corporations. To plan and operate more efficiently and effectively, exploration companies must take advantage of recently introduced innovative and advanced technology specifically engineered to quickly collect high quality data from which high value information can be extracted. It is also important in the 21st century to develop resources in environmentally, socially, and economically sustainable ways.

The knowledge economy can be regarded as the latest stage of development in global economic restructuring and is marked by upheavals in technological innovations. Mineral exploration companies must rely on intellectual capabilities as well as on physical inputs or natural resources and it is imperative they move into the knowledge based economy to succeed and compete globally.  Exploration companies must look beyond dated traditional methods and take advantage of new products and processes developed by the research community. This is where SkyTEM, an innovative and technologically advanced airborne geophysical system, comes from. Developed by scientists, geophysicists and engineers, SkyTEM is designed to satisfy the growing knowledge and financial needs of the exploration community.

The SkyTEM method is applied globally for mineral exploration. As the only system capable of operating in dual transmitter modes SkyTEM delivers accurate near surface data together with data to depths up to 500 m. The system discriminates between weak geological contrasts giving a more complete and accurate interpretation of geology while increasing confidence in modeling deeper geological structure. Other advantages for resource exploration are:

  • Extremely high signal to noise ratio and late time gates for enhanced data quality at depth.
  • Fast turn-off time and early time data for resolving near surface layers as well as more resistive layers.
  • Elimination of signal drift and a one-time calibration procedure so data manipulation is greatly reduced and inversions can be delivered within 2 days of acquisition.
  • All sensors mounted on the rigid carrier frame ensuring all measurements are recorded close to the ground.
  • No operator required in the helicopter reducing weight, fuel consumption and risk.
  • No STC is required for quick installation in a variety of helicopters.
