During a mineral exploration programme in an environmentally sensitive area near Mount Painter in South Australia, a
helicopter was used to position, construct and service drilling rigs in order to avoid the need to create new access tracks.
The drilling programme was designed to optimise the advantages of natural landforms in order to minimise the
environmental impact of site construction and drilling activities. This minimisation of land disturbance reduced the required
amount of rehabilitation measures to the extent where all impacts of the helicopter-supported programme had disappeared
within twelve months of completion of work.
