Abstract

This research focuses on the application of the Spectral Angle Mapper technique on hyperspectral HyMap airborne data and band ratios of ASTER satellite multispectral data together with aeromagnetic data for target area detection for porphyry copper exploration in the Namaqua Metamorphic Province. Improved spectral and spatial resolution of both aerial and satellite remote sensors made it possible to map the lithology and mineralogy in greater detail than in the past. This study pinpointed one location with a high potential for porphyry copper deposits, warranting detailed field verification. The field verification would include geochemical and laboratory analysis to study economic viability of the deposit.
