The Chah Rasteh exploration area is located approximately 25 kilometers southwest of Sarbisheh in South Khorasan Province, and lies within the central part of the Lut Block tectonic zone. The regional geology comprises volcanic units such as andesite, andesite-basalt, and basalt; ultramafic bodies including harzburgite, serpentinite, lherzolite, peridotite, and wehrlite; intrusive bodies such as quartz monzodiorite; and sedimentary and Quaternary units. Preliminary prospecting in the area, was done by processing Aster and Landsat satellite data using the methods of band ratio and color combination of images and least squares regression to determine possible alteration zones and different alteration auras including secondary stains. They were characterized as iron oxides and hydroxides, chlorite and sericite. Two types of mineralization were identified in the Chah Rasteh exploration area. The first type is copper mineralization, observed as disseminated, vein, and veinlet occurrences. The hypogene mineral assemblage includes hematite, pyrite, and chalcopyrite. Secondary minerals include chalcocite, malachite, and goethite. The disseminated, vein, and veinlet style of mineralization, the limited extent of alteration surrounding the mineralization, and its relationship to lithology and structural control, indicate an epithermal vein-type copper deposit. The second type of mineralization is chromite, which, due to its association with ultramafic rock units in the area, is likely of Alpine type.
