Lakhshak deposit is located 28 km northwest of Zahedan in the Sistan suture zone. The rocks in the Lakhshak area predominantly consist of Eocene volcanosedimentary and metamorphosed (greenshist facies) rocks. The mineralogy of the ore is simple and consists of stibnite, pyrite, arsenopyrite, chalcopyrite, sphalerite, and electrum. The Lakhshak deposit is hosted in the shear and altered calc-shist unit which is associated with quartz, sericite-muscovite and sulfide alteration minerals. Based on geophysical studies, using induction polarity and special resistance (IP/RS) in the Lakhshak sheared area, combined with the results of geological, metamorphic and mineralization information, calligraphic calcification units, fault zones and metamorphosed areas have a high potential for Au-Sb mineralization. Therefore, using the amount of changes in specific resistance and chargeability, as well as the intensity of chargeability in the profiles, can appropriately identify the promising area for gold and stibnite mineralizations. This study indicates that the main characteristics of the geology and mineralization of the Lakhshak, such as the nature of the host rock, the form of mineralization, metamorphism and associated alterations, is similar to orogenic gold deposits.
