This article proposed one of the solutions to the important today problem of optimal organization of man-made deposits consisting of mining waste for their further processing. A project is presented to abandon the waste dump facility as the final technological stage of mining operations in favor of storage. The purpose of the project to replace the waste dump facility with storage is to attract additional funds received from the sale of mineral raw materials of man-made mineral deposits. As evidence of the profitability of the considered project of transition from waste dumping to storage of mining waste, a schedule of changes in the cost of overburden and stored rocks over several years was compiled. To conduct a more advanced objective assessment of the effectiveness of the proposed project, possible designs of quarry waste warehouses, their positive and negative aspects in formation and development were considered. The considered warehouse designs and their parameters are theoretically presented in the conditions of the JSC "Kachary ruda" and subjected to an economic assessment. In the process of this assessment, it was necessary and sufficient to take into account only the costs of the transition to the storage of mining waste.
