Abstarct: Copper mining confine of Dian, with an almost area of about 40 km2, is located in 100 km from Damghan toward the south. This zone is at central Iran zone right sided by volcanic arc of Torud- Chah Shirin. By investigating geological schemes and also with outdoor studies of area, it’s shown that, the former rock units of the locale are Andesite lavas, upper and underneath volcanic rocks, and green or red sectorial echo laxyers. This region includes 3 main faces of 1 and 2, and Dian face, in which, observed alterations are embracing Argillic alterations in surface parts, Propilitic alterations around and Silica-Sulfide-Carbonate at central sections and also copper Mineralization. Available main minerals in the rocks of the region contains Malachite, Covellite, Chrysocolla and Chalcocite with a bit of Hematite, Calcite, Silica and manganese which were perceived in checking fine and X-ray segments diffraction. Geochemical explorations of the region consist Univariate, Bivariate and multivariate, which then leaded to detect anomaly zone, And therefore the most proper linear form of the elements that were functioning as stoning and mineralizing elements, was characterized by using cluster analysis and principal component multivariate analysis. Main part of this paper discuses applying Zonality method in order to determine hidden deposits. At first, baxsed on the depth data of this BH4 borehole in Dian face, sequence of orthogonal zoning by using coefficient of contrast methods and normalize index was stated, that Pb,Ba,As,Zn were introduced as super-deposit elements and Be,Ni,Co,CU,Mo as sub-deposit. After that, by using Solovov method, threshold and background values were evaluated. Therefore number of instances and anomaly bound was determined. By applying coefficient indices, active regions of mineralization were specified. The width of second geochemical halo on the third profile which had an obvious anomaly was evaluated. Finally using depth data of this BH4 borehole, Zonality indices of above sub-deposit elements was calculated and graph of depth changes of elements was figured, which tells us that there is an evidence of deep mineralizing in this borehole
