MINERAL COMPOSITION AND ORE-FORMING CONDITIONS OF THE GOLD-POLYMETALLIC LUGIINSK DEPOSIT (EASTERN TRANSBAIKALIA)
The Lugiinsk gold-bearing deposit is regarded as volcanic polymetallic formation deposit, for which the hydrothermal-metasomatic type of ore is specific. Two stages of ore formation were deduced: gold-pyrite (early stage) and gold-polymetallic (late stage). Isotopic data and fluid inclusion study pointed out to low and medium temperatures for ore deposition.
Keywords: mineral composition, native gold, isotopic studies, ore-forming conditions, Eastern Transbaikalia.

INDICATION OF CONCEALED METAL-RICH PLACER DEPOSITS IN TERTIARY DEPOSITS OF EASTERN STAVROPOL REGION
The article characterizes the status of industrial exploration of current wolfram deposits in the North Caucasus. The author sets forward a new way for indication of concealed metal-rich placer deposits with the perspective of their hydraulic borehole mining exploration. Based on analysis and processing of factual archive records of boreholes in the Eastern Stavropol region, the indications of extensive (more than 100 km) concealed (300-550 m) wolfram placers in paleochannel Tertiary deposits are stated. The characteristics of their stereoscopic parameters and wolfram content (0.05-1 %) are given. Preliminary estimate of prognostic resource by category Р2 – 570-630 thousand ton of WO3 is given. It is recommended to conduct prospect evaluation survey through drilling with further resource assessment of category Р1 and deposits of category С2 (2-3 locations) for their approbation in States Reserves Commission to prepare for investment exploratory drillings.
Keywords: Eastern Stavropol region, concealed paleochannel deposits, wolfram, copper, cobalt, zinc, titanium, gold, prognostic resources, hydraulic borehole mining.

NEW ECONOMIC TYPE OF HYDROGENICAL RHENIUM MINERAL DEPOSITS
Because of the appraisal work at the Briketno-Zheltukhinskoe deposit (Ryazan region), the authors refined existing ideas of the deposit’s geology. Geochemical zoning pattern of bed oxidation zone is detected. The genetic model of the formation of economic rhenium ores presented there. There are described features of useable in situ leaching (ISL) technique. Commercial product of ISL is ammonium perrhenate. Because of the above and deposit development conditions, the deposit’s mineral reserves were officially registered by the State Commission on Mineral Reserves (GKZ).
Keywords: rhenium, uranium, molybdenum, geochemical zoning, bed oxidation zone, in situ leaching technique, sorption, Briketno-Zheltukhinskoe mineral deposit, Moscow lignite basin.

PRESENT AND FUTURE OF UNMANNED AEROGEOPHYSICS IN RUSSIA
The current state of the market of unmanned geological systems is analyzed. The main variants of unmanned geophysical technologies and their applicability in solving urgent problems at the present stage of geological activity in Russia are considered. The results obtained by the UAS complexes of multi-rotor and helicopter types developed by the authors are presented, in conjunction with the data of traditional surveys. The possibility of replacing a large proportion of traditional large-scale pedestrian work with a multi-rotor technology, and helicopter ones, both pedestrian and various aerogeophysical surveys, is substantiated.
Keywords: unmanned aerial vehicles (UAV), remote sensing, aerogeophysics, geological prospecting, unmanned technologies, magnetic prospecting.

STUDY POLARIZATION EFFECTS THROUGH INDUCTION METHODS OF ELECTRICAL PROSPECTING ON THE EXAMPLE CHUSOVSKOY DEPOSIT
The paper studied the electromagnetic parameters of the upper section of the ore body Chusovskoy massive sulphide deposit using electrical induction. Various methods are made profiled and area studies of electrical conductivity and the frequency dispersion of the ore deposit area. Past work has shown the fundamental possibility of detection is not coming to the surface of the «blind» massive sulphide ores using shallow induction methods.
Keywords: induced polarization, multifrequency induction profiling, frequency dispersion, apparent resistivity, sulphide deposit.

DISTRIBUTION FEATURES OF CHEMICAL ELEMENTS IN BOGS OF EAST VASYUGAN MIRE COMPLEX
The research of chemical elements and compounds distribution in wetland waters and water extracts from peats of north-eastern part of Vasyugan mire in of Bakchar ore cluster is completed. The background information is obtained in the period of winter runoff low in 2015 by seasonal snow cover. The data for the change of chemical composition of bog waters and peats according the depth of peat deposit and in active layer are obtained. It is established that the decrease of some rare elements concentrations in bog waters according to depth takes place simultaneously to their increase in a mineral phase.
Keywords: Vasyugan mire, Western Siberia, chemical composition, wetland waters, peat.
