Transforming the Mining Value Chain
Geological Mapping with UAVs
The Earth Sciences department, in conjunction with the new ARC TMVC Research Hub, recently conducted a field-based exercise with second year undergraduate students at Freycinet National Park, Tasmania. The purpose was to integrate and teach a useful geological mapping technique commonly used in mineral exploration that records alteration and mineralisation, with high-resolution spatially referenced photographs as a base-layer. The photographs were taken from an Unmanned Aerial Vehicle (UAV), piloted by Dr. Michael Roach from the University of Tasmania and AusGeol.org. The result was a successful exercise that integrated an old technique with new technology.
A second location within the Park is to be the target of a future TMVC project. This project will also utilise UAV-captured 3-D imagery to aid with detailed mapping of key geological features, something that will no doubt become more commonplace in the mineral exploration and mining spheres.
