The mine development project is a set of works, which, due to the uniqueness of mining and geological cond卜 tions, territorial location, climatic factors, lack of the necessary infrastructure, will be subject to a high degree of project risk. The aim of the work is to increase the implementation efficiency of the field development project based on a comparative analysis of the main technical and economic indicators with world industry leaders. Ma- teria/s and methods. Based on the model of the mineral resources of the deposit and the comparative analysis carried out with a reference base with more than forty leading world deposits (benchmarking), a strategic anal-ysis of the main technical, technological, organizational and economic parameters of open pit development has been carried out. The risk analysis, the input parameters used in the preliminary feasibility study of the project are adjusted and updated. The choice of the limiting open pit shell has been carried out, the problem of choosing the mining method and parameters of the equipment used has been solved, and the analysis of the optimal height of the open pit bench and the stages of development of technological blocks of the field have been carried out. Results. The obtained values of the main technical and economic indicators have formed the basis for the formation of a mining plan, as well as an assessment of operating and capital costs, taking into account risk factors. The following most significant risks are identified: availability of staff with relevant experience and competencies required to implement the mining plan; oxidation of long-term storage ore warehouses, which leads to a decrease in mineral extraction rates; high diesel and electricity costs. Conclusions. Based on the identified risk factors, capital and operating costs have been determined and adjusted for the level of energy consumption, the cost of drilling and blasting operations, control of the content of the useful component, loading, maintenance costs, labor costs and general costs
