Magnetic susceptibility measurements have been performed in 6 holes (ROM- 001, ROM-002, ROM-003, ROM-004, ROM-005, and ROM-0066) in Elang. This study aimed to determine the correlation between magnetic susceptibility in drillcore. Magnetic measurements were performed using Suceptibility Meter KT-10. Data processing is done by using software Oasis Montaj Drillhole Plotting to analyze correlations and relationships between hole. The interpretation shows that there’s correlation between magnetic susceptibility values with copper and gold content that contained in mineral alteration. The highest range of magnetic susceptibility value is in chlorite sericite zone (pgm) 0.19 x 10-3 SI to 1459 x 10-3 SI. From the magnetic susceptibility values have also been estimated position of the intrusion, which is in the ROM-006.
