Mineral prospection in one area must be connected to the alteration, mineralization, paragenesis and characteristic each deposit in the reference to make analysis could be accepeted widely by professional and scientist. The availability of information on study area about alteration, mineralization, and paragenesis was exactly needed to explain the deposit on study area from all basic science aspects such the petrography, mineragraphy genesa, texture, and mineral association for analyzing the feasibility of the mineral resource in study area. The objective of study mainly was focused to analyze alteration, mineralization, and paragenesis by using petrography, mineragraphy, XRD, grain counting, SEM (Scanning Electron Microscopy), and Satelite Optic for being correlated to mineralization in study area. Study area were devided to 5 (five) location, Lawe Sikap, Nembak Alas, Salim Pinim, Lawe Pinish, and Lawe Sigala. Prospect areas were suspected have similar mineral characteristic if it examined from regional geology. Although the study area was consisted by some rock types, but in fact all locations were only controlled by one type deposit with very much complexity. The study contained analysis which become the geological reference on study area due to all data were the combination of the samples for analyzing mineral feasibility. In the future this study could be used to the people, especially who actively envolved on mineral research. Alteration zones found on study area have 2 (two) differences after analyzing have been done. Association of mineral alteration on the east side study area, has forming temperature relatively higher than west side that limited by the valley on the middle. Mineralization on study area has similarity between one sample and another mineragraphy samples. Paragenesa on each prospect area also has simililarity, the appearance of Pyrite and Chalcopyrite was disseminated on the surface of mineragraphic samples and Galena and Sphalerite appeared as filling fracture. It indicated that Pyrite and Chalcopyrite were formed ealier than Galena and Sphalerite.
