Dalli Prospect is a Cu-Au porphyry mineralization prospect and consists of two major anomalies, the North and South Hills. The Main objective of the research thesis was to design drill hold targets using three dimensional modeling of the mineralized body at Northern Hill anomaly. The 3D modeling was done using geological, geochemical, geomagnetic and geoelectric data. Geochemical studies were done using 149 soil samples. Basic statistical study, normalization of data distribution, separating anomalies from background, multivariate analysis, consisting of cluster and factor analysis, were done to create single and composite halos maps. The study shows a strong and positive correlation between copper and gold in the North Hill anomaly. From Cu-Au anomaly map, an area of 400m*400m, representing center of porphyry mineralization system, was determined. About 1518 point ground magnetic data were processed and then interpreted using different relevant geomagnetic filters and transforms. As a result, a circular total magnetic field anomalous area of 600m*600m was determined in the center of the region. This zone is locally correlated with Au-Cu nomalies. Susceptibility distribution in three dimensions was calculated using inverse modeling. Also relevant solid model was built for entire and the anomalous region. Using the information of this modeling, three profiles, 1.3 km long, were designed for IP/RS survey. Using inverse modeling of surveyed data, resistivity, chargeability and metal factor pseudo-sections were provided. Moreover, with interpolation of chargeability data, a solid model was also created. Three regions in west, west-north and east-south were recognized as the high potential areas of Au-Cu concentration; which the western anomaly is characterized with the most intensity and extension.
