The vein gold–quartz deposit of Dzhamgyr contains 23 identified ore bodies, which are localized and controlled in the system of interconnected faults. The fault system forms six consistent spatial positional elements. Gold–silver mineralization is observed in all of the veins. The six ore bodies proved in detail are considered as the basis for forecasting and appraisal of vein deposit mineralization. Based on the results of studying the density and shape of the exploration network, the appraisal is carried out based on the influence of the sections of the mining level on the extended contours of the reserves. The morphological structure of the ore bodies and enclosing veins as well as the separation of broken ore enable the use of efficient and low-cost mechanized stoping systems. Integration of geological exploration and actual mining enables significantly improved efficiency of appraisal and preparation of mineral resources for extraction. Optimized geological and economic-geological evaluation of a mining project allows productivity increase, cost reduction and long-term planning of mining and investments.
