Total area coverage is about 16 square kilometres. The major rock units are Mibayataung Group and Plateau Limestone Group. Structurally, the faults are trending NNE-SSW and NE-SW. Two antimony occurrences found in the study area. Sa On Antimony Mineralization are hosted by the quartzose sandstonde of Taungmingyi Member. The Chief ore mineral is stibnite and associated ore mineral is pyrite. under ore microscope, stibnite is found in bladed and radial form and also disseminated in quartzose sandatone. Wallrock altreations are mainly silicification and minor amount of pyritization, post-dating the host rock. Ore controls are both structural (faults, fractures and bedding planes) and lithostratigraphic (quartzose sandstone in Taungmingyi Member). Fracture filling and replacement texture are observed in thr ore microscopic study. The antimony ore mineralization is controled by lithologic, stratigraphic and structural. The ore minerslization ocurrence as confined to the quartzose sandstone of Taungmingyi Memner (of Late Silurian age). The Sa On antimony deposit and wpigenetic in origin as judged by its geological characteristics. According to the report of Department of Geological Survey and Mineral Exploration (DGSE), November, 2011. estimated tonnage of Sa On Antimony Occurrences 1 and 2 is 4725 tonnes. Average AAS assay results of metal contents are Sb-27.61 % Cu-13 ppm, Pb-60 ppm and Zn-160 ppm. Based on thr geological, mineralogical and geochemical signatuures, typical features, characteristic of mineralization, thr antioy ore mineralization of Sa On area is stratabound, epigenetic in origin and epithermal ore deposits type.
