THE ORE POTENTIAL OF THE FAR EAST
The article presents data on mineral resources base of ore minerals, diamonds and coal of the far Eastern region, the main attention is paid to the gold potential of Magadan region, Chukotka Autonomous district and Republic of Sakha (Yakutia). Given the quantitative parameters of the production of ores and concentrates currently and on prospect up to 2030, based on the materials of state accounting and legal solutions for the development objects [3, 4]. Due to the significant depletion of the ore potential of the region, primarily precious metals and diamonds; given the conclusion about the necessity of active development in the region search and regional forecasting and mineragenic work.
Keywords: Far Eastern region, Magadan region, Chukotka Autonomous district, Republic of Sakha (Yakutia), mineral resources base, mineral raw materials, mining, production of mineral raw materials, reproduction, gold, silver, copper, tungsten, tin, rare metals, iron, diamonds, coal.

GEOLOGICAL STRUCTURE AND ORE PROCESSES OF THE LOMAMSKY POTENTIAL ORE-GOLD DISTRICT
Lomamsky ore district is located within Timpton-Uchur block of Aldano-Stanovoy shield and characterized by intense manifestation in step Mesozoic tectonic-magmatic activation of alkaline and subalkaline magmatism and related alteration processes of different formation type. Mineralization is localized in different lithologic and structural environments, such as subhorizontal zone of increased permeability in clastic-carbonate strata in the platform cover and Jurassic clastic strata, on exocontact of intrusions of Mesozoic age; in steeply dipping faults, maped to deeply metamorphosed rocks of Achean age, as well as in large Mesozoic intrusions.
Keywords: Aldan Shield, Yakutia, magmatism, metasomatite, gold, beresites, gumbaites, argillizated rocks.

MINERAL RAW BASE OF BENTONITES OF THE CRIMEA REPUBLIC
The mineral raw base of bentonites of Crimea republic is explored. Interdependence between the placement of the bentonite deposites and manifestations and such aspects as tectonical structure, formation and mineragenic groups is given. The geo-indasrtial classification of bentonite objects is done. The basic ways of exploration and exploitation of mineral raw base of bentonites is recommended.
Keywords: Bentonite, bentonite-like clays, deposityes, manifestations, interdependence, structure, formation, minerageny, type, geo-industrial, recommendation, Crimea republic, Russia.

DEPOSITS OF DETRITUS-BONE GEOLOGICAL-INDUSTRIAL PHOSPHORITES: THE ENVIRONMENT OF FORMATION AND THE POSSIBILITY OF DEVELOPMENT
The situation of accumulation of deposits and manifestations of detritus-type phosphorites in the maikop deposits of the Caspian and North-Caucasian phosphorite-bearing basins is considered. Ores belong to the complex phosphate-rare earth-uranium type, easily enriched for obtaining nitrogen-phosphorus fertilizers, extracted when obtaining the whole product – uranium concentrate. Economically profitable and economically safe is their production by well drilling.
Keywords: phosphorites, deposit, formation, development, geological-industrial type, uranium, fertilizer, nitrogen-phosphorus, hydrodevelopment, maikop, paleogene, neogene, Kalmykia.

EXPERIENCE OF THE USE OF GEOELECTRIC CHEMICAL METHODS FOR SEARCHING ORE DEPOSITS
Geoelectrochemical methods of prospecting for ore deposits considered. The methods are applied to detect superimposed dispersion haloes of ore elements in different landscape conditions. The methods can be used most effectivelly in prospecting for deep-seated deposits in covered areas in integration with the geophysical investigations.
Keywords: geoelectrochemical methods, superimposed haloes, covered territory, deep-seated deposits.

THE SPECIFIED HYDROGEOLOGICAL MODEL OF OBJECTS OF THE URAL FOLDED REGION
The basic understanding of the hydrogeological conditions of Ural Folded Realm (UFR) has been formulated in «Hydrogeology of USSR. Vol. XIV (Ural)», 1972 . In the following 45-year-long period absolutely new ideas about hydrogeological conditions of UFR didn’t emerge. Based on the analysis of research results of past years and newly performed works the updated natural hydrogeological model of the objects of study within the UFR is offered, it helps to avoid rough mistakes in counting the operational reserves of fresh groundwater, in the predictions of flooding of solid minerals deposits as well as in the assessments of groundwater contamination from exploitation by the UL in a modern period of declining reliability of control observations and saving expenses for studying the hydrogeological conditions of researching topic.
Keywords: Ural folded realm, hydrogeological conditions, underground runoff, jointing, weathering crust.

RESOURCE-SAVING WELL DRILLING TECHNOLOGY BY HEAVY LAYING WITH HYDRAULIC DISTRIBUTOR AND THIN-WALL DIAMOND CROWNS
The trend of prospecting and exploration of deposits useful on deep horizons of the earth’s interior imposes higher demands on the quality and cost of geological exploration. The design of a bottom-hole configuration with a hydraulic distributor and thin-walled diamond crowns is proposed for drilling wells with a reduction in resource costs, providing an increase in the representativeness and informativeness of the core.
