The results of the analysis of the influence of the main factors on the structure of the production capacity of a gold mining enterprise are presented. The possibility of managing the attractiveness of a gold Deposit development project by regulating the volume of ore production and processing at various stages of mining development is shown. It is established that the less homogeneous the distribution of the content of valuable components in the field array and the lower the distribution density relative to the average content, the greater the increase in the net value added to the indicator of the excess of ore production over processing in the initial period of development of the field. The main advantage of the method of optimizing the structure of production capacity of gold-mining enterprise in the development of gold deposits is to increase the extraction of gold from mined more ores in the first phase during the first 5 years of development for the temporary warehousing of the poor of the extracted raw materials in the storage warehouse. The proposed optimization method is most effective for projects that are characterized by ore deposits with an increase in the gold content with depth. The implementation of the production capacity optimization method for such fields will allow involving previously non-promising fields in profitable development.
