Modeling of mineralized zones and evaluation of copper and gold resources in the southern part of Dali Cu-Au porphyry deposit, Markazi province

Taking apart and modeling of various mineralized zones and evaluation of their reservoirs and resources in porphyry deposits is so important. In this research the main aim is modeling of mineralized zones in the southern part of Dali deposit. According obtained results from exploration drilling in southern part of this deposit until now, three zones, that they are consist of oxide, transition and hypogene zones, are recognized. For modeling of the southern part of Dali deposit, first of all data of 6 boreholes of this part was regularized in a database. Then three dimension modeling zones in this deposit was made by RockWorks14 software and combining data with surface geological data. Subsequently, amount of copper and gold resources in every three zones was separately evaluated by inverse square distance method. Results indicate that the most concentration of Au-Cu bearing ore is situated in hypogene zone. Moreover, transition zone in some parts is consists of Cu and Au enrichment and it is possible that part of transition zone is introduced as supergene enrichment zone.
