The southern part of Mullah Ahmad area is located in 60 km of southwest of Nain town, along the Urumiyeh-Dokhtar volcanic arc. Mineralization is mostly associated with hydrothermal alteratio in the Cenozoic felsic units of pyroxene andesite and trachy andesite. In this study, remote sensing studies were conducted to identify the alteration zones in relation to mineral and copper mineralization in the region. For this purpose, the satellite images of the study area were pre-processed and then analyzed by false color combination, band ratio, least squares regression and spectral anlgle mapper (SAM). Argilic, Flick's alterations were identified in some propylitic and siliceal alteration regions. After that, the Kalchoveye index and the Lakht mountains, which had similar altrations similar to those identified for the copper-gold mineralization, were identified on the study area and the alteration The two areas were also studied. Subsequently, the Kahwiyeh copper-gold vein deposit was investigated due to the similarity of the alterations in the area with the alterations identified as alterations in relation to copper-gold mineralization and for determining the criteria of exploration. In the field visit of Primary sulfide minerals, including pyrite, chalcopyrite, galena and sphalerite, were oxidized to a significant extent. Observations were made from different mineralization zones of this ore deposit. The mineralization of the deposit was carried out in both primary and Secondary (Supergen). In the secondary mineralization under oxidation and weathering conditions, the phase Oxide including hematite, guanidine, limonite, malachite, azorite and copper. After examining the polished sections of the iris and the wall of the vein of the vein, a geochemical analysis was carried out. In some samples, the grade of gold was more than 1 ppm (usually the gold standard for gold) and the arsenic grade More than 2000 grams per ton, indicating the presence of an enriched gold zone within the range. A percentage of samples had copper grade, and a large part of them had copper with a grade of more than 0.2%, indicating the presence of a poly-metal mineralization zone in the region. Mineralogy and geochemical studies of Kalchoever deposit showed that this deposit is of epithelial type with volcanic volcanic rocks. In the end, a series of similar potential points of Kalchivia and the Lakht mountains were introduced for further exploration.
