To carry out the geostatistical studies, a spherical model was fitted over an empirical variogram. Plotting the empirical variogram in different directions, and it showed that there are neither geometric nor regional anisotropy. For simulating via Sequential Gaussian Simulation (SGS) method, data were transferred to standard normal and then simulated 100 times (in this way 100 realizations were created). All of the realizations were honor to histogram and the variogram, so all realizations are valid. E\_Type and p...

Sungun Porphyry Copper deposit is located 75 kilometers northwest of Ahar and 130 kilometres northwest of Tabriz. In order to model the deposit and estimate its reserve, 31068 input data gained from 152 boreholes were used. Cu grade was selected as the major regional variable on which the present research has focused. All of the available data were changed to 12.5-meter composites so that statistical equalization could be reached. Studies indicated that Cu input data had single - population characteristics. To car...
