This geochemical exploration project was based on the contract No. 4425-300 between GSI and Pars-Peyazma Consulting Engineers.
To field operations consist of 14 experts travelled to the area that includes four maps of 1:50000. Each sheet was sampled separately. The field operation lasted for 12 days. During the operation the 838 geochemical samples and 196 heavy mineral samples were harvesting.
All samples taken for geochemical analysis of 44 elements were sent to the Zarazma laboratory. 43 element analyzed by ICP-OES method and the gold analyzed by Fire Assay method.
The results of data processing for geochemistry and heavy minerals show that the sheet of Rudbar has high mineral potential and promising zones. 45 anomalies were presented for field checking. They are of different types, but majorly contan Au, Cu, Pb, Zn, W, Mn, Fe and Sn. It should be noted that there are mineral indices and abandoned mines in the area, that most of them have copper mineralization. Factor analysis and correlation coefficient matrix show a strong relation especially between elements Au, Cu, Pb, Zn, and Mn.
This project described the anomaly maps of 10 elements. In addition, important heavy minerals were plotted in the context of geochemical maps. Finally, combining the available information, eight promising areas with mineral potential were introduced.
45 anomalous zones controlled by taking 77 mineralized samples, 59 heavy mineral samples and 7 samples for polished and thin section analysis. The final result of the anomalies has been described in the report.
