Abstarct: Exploration methods are divided into two categories: direct and indirect methods. Direct methods such as exploration drilling are expensive, slow and possess high accuracy. However geophysical methods are among indirect methods that need low time and cost and also explanation and interpretation of their results are difficult.This research is aimed at using the geoelectrics methods including inexpensive methods .Ways to identify quality location karst bauxite beaddrosed,if they get a positive response alon step in reducing the cost of exploration and exploition of these deposits will be removed. For this purpose, in Taguee 4 & 5 bauxite mineral area, 82 electrical soundings on 3 lines have been planed and surveyed. Taguee region is one of the Jajarm bauxite mines, in which extraction activities have been carried out rarely and most drillings have been made for exploration purpose.data surveyed by the standard curves previously interpreted by the supervisor and the result of initial modeling surpac software have been modeled.in addition to capabilities Surpac software speculatious about exploring databaxse information is built.comparing the result of the exploration boreholes and geoelectrics shows the boundary of the footwall dolomite and bauxite are clearly identified and partially corresponded to the laxyers above the laxyer of geoelectrics information obtained from exploration boreholes dolomite data doesn watcht.at least there are four geoelectric laxyers in the modeling results,Taguee 4,5 are located within the area mineral bauxite Jajarm show.for better understanting and more compere hensive, the result are display as two dimensional.the next step according to available exploration boreholes data in the Jajarm bauxite mine because drilling has not been done on a regular lattice(the most borehole are along eachother)and still exploration drilling in this area will be done and also for the reson of no detailed breakdown laxyers of hard bauxite,shilly bauxite and kaolinite bauxite with geophysical data,ability to calculate the exact volume and bauxite extent of the area is not possible, however according to the specified the foot wall boundary of bauxite structure from dolomite laxyer, the measuring level of dolomite hanging wall surface until the ground level is possible, which is comparable with dolomite hanging wall through geophysical data obtained.
