Abstract—Many diverse criteria should be considered to select the potential zones for mineral exploration. The study aims to provide potential map for porphyry copper zones in the Nuweiba area based on the criteria derived from geologic, geochemical, and remote sensing data. Field investigations, remote sensing and GIS techniques were applied jointly to prepare and integrate several factors contributing to mineralization occurrences. The remote sensing techniques such as Band Ratio (BR), Relative Absorption Band Depth (RBD), Principal Component Analysis (PCA), Minimum Noise Fraction (MNF), and Linear Spectral Unmixing (LSU) were used to define the geological characteristics of the study area including lithological units, structural features and hydrothermal alteration zones. Weight Linear Combination (WLC) was adopted as suitable GIS technique to integrate spatially several criteria having different weights of importance for mineralization occurrences. These criteria involve the lithological units, lineaments, major fault, alteration zones, and stream sediments anomaly. The weight of each criterion was evaluated using Analytical Hierarchy Process (AHP). The results of applications in this study provide acceptable map defining the zones of porphyry copper deposits in the Nuweiba area.
