Abstract: This study represents a part of an ongoing research program to evaluate the lithologic mapping capabilities of NigeriaSat-1. Rafin Gabas is located in Nasarawa state and falls within the Younger Granite province of Nigeria. Wolframite and cassiterite have been found to occur within this area.The topographical map of the study area was generated from the SRTM (Shuttle Radar Topography Mission Data). The DEM was converted into a contour map using the ERDAS and ArcView softwares. The NigeriaSat-1 image of the area was subjected to various image processing techniques such as edge enhancement, Principal component analysis and filtering. Samples from wolframite-bearing-quartzite-veins were analysed and old tin mines were studied. The various ancillary data were integrated in ILWIS software. Geological information such as lithological boundaries and lineaments were derived from the NigeriaSat-1 image. The lineaments were found to occur in the NE-SW direction and they range in length from 300 Km to 2.5 Km and some cut across rock boundaries. The results of the XRF analysis show an average of 62% Wo . Tailings from the old mines were observed to 3 contain some amounts of Cassiterite which could be reworked. The various data generated were integrated in a GIS environment and a mineral probability map was produced.
