Shurchah area is located 60 kilometers to the southeast of Zahedan. Zahedan granitoides and dioritic dykes have intruded in flysch sediments of Eocene age. After collating of factors such as stratigraphy, lithology, tectonics and topological gravity of drainage patterns, 82 stream sediment samples have been taken from streams. Samples were analyzed using ICP-MS and AAS analytical methods. For eight elements Au, Ag, Cu, Pb, Zn, As, Sb and Hg factors such as error, frequency distribution, amount of sensored, background, threshold, anomaly, mean, mode and standard deviation, calculated individually. Among these elements, Sb with an average value of 10 ppm has been considered as anomaly regarding the spatial situation of the anomaly; it was determined to be in the central part of the study area. In addition, strong positive correlation was observed between gold- arsenic and gold- antimony.
