Mineral spectral analysis isn’t merely algorithmic processing—it is an art informed by experience. through customized mineral-system workflows, rigorous data calibration, favorable data-driven feature extraction, and expert manual refinement. This project utilised medium-resolution multispectral Aster (30 m resolution) and Sentinel 2A (10 m resolution) imagery integrated with reclassified regional geology and magnetic faults and mineral systems analysis to identify favourable mineral targets for copper and gold exploration in a regional scale. VNIR and SWIR data were processed in ensuring precise co-registration, atmospheric correction, and consistent spectral analysis. The workflow enabled detailed mapping of alteration minerals, iron oxides, and structural features, delivering reliable targets to support focused and cost-effective on-ground copper-gold exploration.
