Airborne Geophysics

Airborne Geophysics in Mineral Exploration

European UnionUnited Kingdom

Summary

Airborne geophysics was mentioned by experts as a key innovation in the D 3.2 process (see report).

Description

Airborne Geophysics has been identified as one of the emerging technologies capable of finding potential mineral deposits under cover and at depth. Examples include recent research into Airborne IP (induced polarization) and SQUID (High temperature superconducting quantum interference device) electromagnetic applications as well as the use of drones in geophysical surveying.

No real stand-alone innovations have been made in the last 10-15 years, however developing IT technologies and algorithms have refined certain aspects of Airborne Geophysics and continuously improved the use and applicability in mineral exploration.

Impact on the mining value chain

  • EXPLORATION (incl. permitting)

Exploration

  • safe and fast remote exploration
  • greater depth exploration
  • reduced environmental impact

Transferability

It was found that, in terms of airborne geophysics, the mining industry can both learn from other industries (e.g. oil and gas) and enable other geoscience sectors to implement workflows and research (e.g. urban geoscience and geophysics - hydrogeology/ contaminated land).

Innovation drivers and barriers
Drivers
Policy
EU research strategies and grants: H2020, Finland's Green Mining Programme, etc.
Economic
Reduced cost and time of exploration in remote and covered greenfields areas
Other
General technology development and availability (hardware, software, processing power, algorithms, drones etc.).
Other
Business needs and demands (exploration at depth and under cover).

Good practice areas

Resource security
Advanced airborne geophysical methods allow the detection of mineralising systems and deposits and therefore the future discovery and security of supply. Refer to key papers, such as Lee et al. (2002) and the use of SQUID in the discovery of the Sakatti Ni-Cu-PGE deposits in Finland.
