 The relevance. These are first geophysics studies in Mesgaran exploration area. Based on geological mineral zone, mineralization was proven. type this area identified as Cyprus-type massive sulfide. complexity structure determines need to use geophysical research forecasting planning mining drilling operations. main aim study is application search deposits modeling environment. Object: area, Khorasan province, Methods. order obtain more subsurface information, IP Rs were used. Five profiles designed implemented geoelectric surveys. Overall, five (P1 P5) read dipole-dipole arrays with 784 points. taken east-west north-south along parallel zones. array parameters AB=MN=20 m, jump=20 m up 6 jumps MN. Results. general, four types anomalies these investigations. Which some extent revealed association rocks area: 1) low electrical resistivity, well polarity, often correspond quaternary alluvial deposits; 2) abnormalities high resistance, which consistent limestone’s superficial; 3) polarity south form altitude agglomerates; 4) higher relative resistance associated igneous masses, composed andesitic-basaltic rocks. position 5 profiles, optimal location drills determined.
