Among the gold deposits of the North-East of the USSR, attributed to the gold-quartz formation, a special morphological type of mineralization in dyke rocks.

Studies conducted by the authors during 1973-1975 on gold deposits of the gold-silver formation, allow us to draw certain conclusions and offer specific recommendations on the complex and rational sequence of exploration work at various stages of exploration of deposits belonging to this structural and genetic group ...

Gold deposits, confined to mineralized zones of crushing and buckling of sandstone-shale strata, have specific features of structure. They differ from the widespread quartz-gold deposits of vein type not only by morphology of ore-bearing bodies, but also by the structure of ore fields confined to large discontinuous structures of deep embedment, long and complex history of mineralization development, significant scale of hydrothermally altered and mineralized rocks, predominant role of microscopic and sometimes dispersed gold in ores. If, speaking simplistically, for vein quartz-gold deposits, the problem of prospecting and subsequent exploration is reduced to finding veins and identifying areas (blocks) with balance ores in them according to the already repeatedly tested exploration network, the theoretical aspects of the methodology of exploration of gold deposits of the type of mineralized crushing zones and their practical solution still need to be developed. ...

The economic evaluation of mineral deposits should be based on the cost assessment of proven reserves of mineral raw materials to justify the acceptable level of socially necessary costs for its exploration, production and processing. Such an assessment is also necessary to ensure the most complete and rational use of subsoil. ...

Within the ore field of the studied gold deposit sandy-shale deposits of the Lower Permian with thickness up to 2000 m are spread. The deposit is located in the near-axial part of a brachyanticlinal fold of meridional strike. The meridional and north-eastern and south-western breakers of the chipping type are widely developed.

Economic efficiency of exploration of any deposit depends on the correct choice of technical means and rational placement of the necessary number of exploration intersections. The latter is determined, as a rule, by the degree of variability of the main parameters of the field ...

During prospecting and exploration work on deposits of solid minerals there is a need to study the deposit from the surface. For this purpose, ditches, pits (with or without sections), shallow exploration wells of core drilling, or a complex of these excavations is used. The method of exploration (density and configuration of the exploration network, type of sampling) is determined in all cases on the basis of the study of geological factors. If it is possible to apply all these types of exploration, it remains to decide which of them should be given preference. Other things being equal, the most economical method of stripping should be chosen, which at the lowest cost of time and material resources will give sufficiently reliable data on the explored object.

The conditions of prospecting and exploration of deposits, as rightly noted by V. I. Smirnov, are becoming more and more complicated every year, as most of the work is carried out in hard-to-reach areas and in an increasingly complex geological environment. In modern conditions, when the economic factor in the exploration of mineral deposits is given decisive importance, the problem of identifying such deposits and ore bodies, which contain the main industrial reserves of this type of mineral raw materials comes first...
