Gold deposit in the area occur in quartz veins and as fine gold in sandstone. Gold bearing quartz veins of the target area occur mainly in east-west trending faults system and fractures cut in green stone belts. Gold mineralization is mainly confined to the metovolcanic, metasedimtntary rocks of green schist facies (schist’s) intruded by granitiod rocks, and over lain by Nubian sandstone which exposed at the western side of the area .Nubian sand stone contain fine gold accumulated by the River Nile through slow currents forming ancient beach and terraces. The quartz veins contain metal sulfide deposits such as pyrite,. The ore have been largely mined by local Artisnal miners. Chip samples of quartz veins show grade between 1.4- 58.4 ppm, and the sandstone between 1- 25 ppm .Visible gold also observed as nuggets, plates, and fine grains.
