Abstract	Abstract Our research was conducted in Panikaban Area, Ponorogo Regency, Central Java, Indonesia. Based on the result of field data collection and analysis which has been carried out in the laboratory, stratigraphy study area was divided into 6 unofficial lithostratigraphy units and 2 litodem with the sequence of an old rock to young as follows: Halang volcanic breccia unit (Tmb), Halang sandstone unit (Tmbp), Kumbang andesite lava unit (Tma), Andesite intrusion (Tmi), Tapak volcanic breccia unit (Tpb), Tapak sandstone unit (Tpbp), Tapak limestone unit (Tpbg) and Alluvial (Qa). Rock lithology conditions in the research area are also included in the category in experiencing the process of alteration and minerallization, making the study area was being divided into three zones of alteration, namely: argillic zoning, propylitic zoning, and sub-propylitic zoning. Mineralization found in the research area is relatively associated to quartz veins (veins or veinlets) in the Halang sandstone unit, as well as on the intrusion body in the study area. Ore mineralization contained in research area such as sulfide minerals, such as: pyrite (FeS 2), chalcopyrite (CuFeS 2), galena (Pbs) and bornite (Cu 5 FeS 4). Results of the analysis of AAS (Atomic Absorption Spectroscopy) or atomic absorption spectrophotometry is used to determine the content of sulfide mineral elements contained in a sample. The analysis shows increase in sulfide mineralization which is characterized by the abundance of the elements Cu, Pb, Zn, Ag, Au, some places elements of Au increases compared with other elements.
