In this study, we investigated the use of stainless steel electrodes in metallic ore deposit exploration using induced polarization (IP) data. Nowadays, IP data are measured using multi-electrode and/or multi-channel measurement systems. The major advantage of this system is that a large amount of data can be collected in a short time. However, large numbers of non-polarized electrodes are needed in IP survey applications with these systems. Therefore, the data acquisition time is increased, and thus geophysical operational costs increase and we lose the advantage of fast data acquisition by the multi-electrode measurement system. We tested the use of steel electrodes for IP measurements using the superiority of new-generation devices to eliminate the polarization potential during measurement. We conducted IP measurements at a known metallic ore deposit located in Central Anatolia in Turkey to compare different data sets collected using steel electrodes and Cu-CuSO4 non-polarized electrodes. We investigated different time cycles (0.5 s, 1 s, 2 s, 4 s) to determine their effectiveness for steel electrodes. The results for the 2 s and 4 s time cycles were satisfactory. We also compared thin-surface and large-surface non-polarized electrodes and steel electrodes using the results of the 2 s optimal data acquisition time. The data obtained with large-surface and steel electrodes were more stable than the data obtained with thin-surface non-polarized electrodes. Additionally, we compared the use of all electrodes in parallel and in series. The results showed that the serial approach could also be used with appropriate measurement commands.
