Abstract:
Exploration and mining companies in Australia are faced with the challenge of locating deep ore deposits potentially buried under hundreds of metres of cover sequence materials. This research aims to investigate how the integration of hyperspectral remote sensing and surface geochemistry can be used to recognise signatures of alteration potentially associated with buried mineralisation. While each of these methods are individually mature, their combination for the purpose of mineral exploration is novel. Integration of methods including classification of spatial data and radiometric imagery, hyperspectral alteration mineral mapping and lithogeochemical analysis has produced results that might benefit exploration within the study area of the Central Gawler Gold Province. Further, the methods developed have the potential to be applied in other areas and therefore benefit the wider Australian and international minerals industry, especially in areas where there is no obvious expression of alteration at the surface.
