The significant role of the gold mining industry in the development of the Russian mineral resource system determines the search for new organizational, technical and geotechnical solutions to improve the completeness and efficiency of deposit development. Most of Russia's gold deposits are in remote, sparsely populated areas, where there is a lack of energy, transport communications, and infrastructure. It is shown that the Ryabinovoe gold deposit, located in the Republic of Sakha (Yakutia), is characterized by a complex structure, relatively low occurrence of ore deposits and a widespread in the value of mineral raw materials. Features of the Ryabinovoe deposit consist in a complex structural structure and alternation of mineralized gold-bearing and low-gold-bearing or ore-free areas of various capacities and complex morphology. The main criteria for open Geotechnology have been clarified and justified. This ensures safe and efficient development of the Ryabinovoe field with the achievement of the maximum possible total discounted income and the shortest recoupment period for the project. In general, an integrated approach is the basis of the development strategy of the Ryabinovoe gold deposit. It includes increasing the level of extraction of useful components, increasing the production volume and a differentiated approach to the choice of a method for processing ores of different quality. It is shown that the achievement of rational production capacity in the complex development of the Ryabinovoe gold deposit is based on optimizing the variation of the onboard and average gold content with justification of the ratio of production capacity of the mining and processing cycle.
