Abstract: Due to long-term exploitation of gold deposits, the current stage in development of mining systems is characterized with decreasing reserve replacement, degradation of the mined ore quality, complications in geomechanical environment, higher mining costs and aggravation of the environmental situation in the region. Constant depletion of rich and easily accessible gold deposits leads to changes in the category of reserves and inferred resources. At the same time, steady development of equipment and technologies for prospecting, exploration, extraction and processing of ores with optimal geotechnological parameters to a great extent compensate for the decline in the quality of gold-bearing raw materials mined at the deposits, ensuring an increase in gold production in the country. The article reviews specific features of geological and mining conditions in development of gold deposits at the Nizhneyakokitsky gold field, located in the Republic of Sakha (Yakutia). It is shown that due to a significant variability of gold grades mined at the deposit, a special attention should be paid to the quality management of the ore extracted and delivered for processing. It has been proved that in difficult natural, climatic and mining conditions, effective development of the deposit reserves depends on a differentiated approach to the selection of a method to process ores of different quality with the justification of a rational structure of the mine's production capacities and processing facilities.
