    • Antimony is a toxic chemical element with the symbol Sb and an atomic number of 51. A lustrous grey metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb2S3). Antimony is a semimetallic chemical element which can exist in two forms: the metallic form is bright, silvery, hard and brittle; the nonmetallic form is a grey powder. Antimony is a poor conductor of heat and electricity, it is stable in dry air and is not attacked by dilute acids or alkalis. Antimony and some of its alloys expand on cooling. Antimonyore occurs mostly by low-temperature hydrothermal solutions and shallow, fillingcracks and cavities areirregular shapes. Some of the primary sludge has under gone enrichment by weathering residue, forming oxideore. Mixture (alloy) with a black tin battery used in industrial, chemical pumps and pipes, wire wrapping, roofing sheets, Bab bitt metal, white metal, solder. Anti monyoxideis usedfor (enamel) ceramics, paint pigments and glass. Anti monysulfide is used in vulcanizing rubber industry, for trisulfide matches and antimony.

      Based on the Regional Geology, area of inquiry composed of Kemum Formation (SDk). This formation consists of sedimentary rocks altered low level: slatestone, slate flakes, argillic, regularly laminated siltstone with local sandstone and conglomerate, rarely limestone recrystallization.

      The vogelkop bedrock north (Bird‟s head, or the Peninsula Doberai) Sorong fault zone south of the Paleozoic age (d‟Audretch and II, 1996; Robinson and Ratman, 1997, 1978; Ryburn, 1977; Visser and Hermes, 1962).

      Low-grade metamorphic rocks consist of slate , quartzite, greywacke, dominate in the west, where the old silurian graptolite obtained in one area and covered by rocks of upper carboniferous or Permian age of the lower and younger rocks degrees higher of kyanit skis, very common in batian east, where the old ostrakoda devon found in one place.Basic rocks are complex cut by a Sorong fault zone but a long mass of

      Begins with the study of literature in the form of maps, papers, journals and writings of other scientific-related research topics. After compilation and analysis of secondary data, survey plans can be arranged.Retrieval of data from field observations of rock outcrop, especially the mineralization and alteration, stripping in selected locations as well as making the chip samples from outcrops, soil samples and concentrates (stream sediment and panning).Observations on the Antimony include observations of structure and texture, its relationship with the surrounding rocks, observations of Geophysical and mineralogy.

      Result of geological mappingthis region are composed of sandstone and mudstone units that have under gone the most low-grade metamorphism that is often encountered as slatestone. Jointed outcrops, a layer with a slope almost vertical-upright, foldminor, minorfaultarea, the development of straightness of the waterfall, and brecciation. This indicates a very strong fold structure, which later developed into a reverse fault in the study area. Fold axis and the field is estimated trending reverse fault is relatively north-south.

      Results of geophysical, get the value for the charge ability and resistivity. From these results, there charge ability values over 30% of the points in N-1 through N-5, in other words with in a rock body that has a high metal content.

      Based on the result of geophysical interpretation after being correlated with geological data available, it can indicate location and distribution of base metal mineralisation (Antimony). In vertical condition the anomaly patterns illustrate availability of anomaly zone as spotted to the depth.
