Abstarct: This thesis aims to explore the copper deposit Duchileh - Miami model results and interpretation of the data - the resistivity and induced polarization (IP) harvested during multiple profiles on the deposit . The deposit is baxsed on objective evidence and geological interpretations of the results in the region - veins and some scattered nature , so the best method of geophysical exploration of the deposit , are method for electrical resistivity and IP. Geophysical studies on ore mine in areas where outcrops were expanded and harvested in areas where data indicate the possible presence of copper mineralization, but there was an idea of the depth, was carried out. Followed by removal of the deposits studied geophysical data, 8 array of structures with dipol - dipol , each with an approximate length of 280 meters , using ABEM SAS4000 cognitive phases north and south ground conditions were almost identical , done. Inverse Modeling of the data - the resistivity and IP software RES2DINV ver. 3:54:44 perform the two-dimensional sections the results were interpreted . The Oasis montaj software using all the sections together again combines a three-dimensional view of offering interpretations that provide accurate and comprehensive exploration of the deposit was terrific . Two-dimensional and three-dimensional view of the interpretation of the combined slice it also depends very well with geological evidence and information obtained from chemical analysis of samples taken from trenches will show . geophysical model of the data , creating the potential for mextallic minerals, each study phase (Phase northern and Phase South) has been identified . Also, the interpretation and evaluation of two-dimensional cross sections of three-dimensional view of the and creating a cohesive and close association between the mineralization at depths up to 30 m in profiles was diagnosed executive . Fractures in the region of the profiles detected that these fractures are hopeful that the ore locations can be mextal speciation . In this regard, on one of the profiles spot for drilling operations for exploratory studies suggest that information obtained from this drilling , results obtained from the model and interpretation of geophysical harvested , resulting in a high success rate confirms this impression geophysical track.
