This research demonstrates an effective procedure for assessing the impact of ore-controlling factors of orogenic gold. In this paper, ore genesis factors such as heat source, migration pathways and depositional environment were investigated. The procedure subsequently applied the weight of evidence model to weigh and quantify the spatial relationship between the control factors and 30 known gold deposits in Kelantan, Malaysia. The results show a strong correlation pattern between the deposits and the considered factors such as the NE-SW faults, the intrusive rocks and the sedimentary rocks. The NW-SE fault shows a weak correlation pattern with the deposits.
