Tortkuduk Central is a part of Muyunkum uranium deposit of the Chu- Sarysu depression, Southern Kazakhstan. Because of the large extent of deposit & geological characteristics the deposit divided into four sections: Muyunkum South; Tortkuduk South; Tortkuduk North; Tortkuduk Central. The grade of uranium mineralization is a variable from 0.2 to 1.0 kgU/t. Based on operating experience of NAC Kazatomprom and work parameters of pilot plant on each site of JV KATCO were defined: *Method of uranium extraction is In Situ Leaching with working reagent of sulphuric acid; *Each site is planned for the production of 1000 t U per year. According to preliminary data the reserves were estimated with average grade content. These data were taken for pre-feasibility study of this project. At present, exploration continues and will be finished in two years. Eluates of Tortkuduk Central will be transported to the Tortkuduk South site's central installation which has complete cycle of processing and production. This study evaluated the total investment and the operating cost. The economic evaluations show that the project will provide an Internal Rate of Return, a Net Present Value and a pay back period. Sensitivity and risk analysis were performed, that provides information about the project resistance at various situations
