In this study, the prediction of acid mine drainage was done by measuring dielectric contrast of sulphide mineral and its environment. It causes amplitude contrast of radar wave reflected by rock layer. This measurement was performed using electromagnetic method by use of Geo-Penetrating Radar or Georadar (GPR). The frequency of measurement was 250 MHz with perpendicular broadside antenna. It took place at pre-mining area whereas the surface soil was dry. GPR data was processed for enhancing data and amplification. The result of this research showed that the overburden and interburden layers were dominated by claystone or siltstone with little sandstone. The multiple that appear in the processed data looks relatively regular and evenly distributed in the layer, not spots which are characteristic of sulfide minerals.
