The problem of additional water intake from pressure horizon of Arevic intermountain basin is solved, based on evaluation of field investigations results. The problem of three-layered geofiltration medium is solved on JBM computer using "Topaz" program. The possibility of additional intake, about 2,2 times as must as present 830 l/s, is proved by means of mathematical modelling. The estimated decreasing of level is less than maximum permitted level of pressure water in wells. The number of water intake wells, their yields, efficient location, duration of water intake and possible guantity of taken water are also evaluated.

The ore-enclosing rocks of the Sotsk deposit are subject to metamorphic and metasomatic processing. The separate ore bodies with depth combine in one (stock). The main parts of mineralization is timed to extreme parts of gabbro and peridotites, which are distinguished by their petrophysical parameters. The character of gold mineralization distribution testifies, that upper part of deposit is most perspective. The stage of intensive mineralization is distinguished, the mineralization fades with depth. The hard foundation, located at the short depth, is broken up by tectonic breaches which were favourable surroundings for penetration of hydrothermal solution.

The methods of revealing the buried morphostructures in the volcanic regions of Armenia by means of the morphological analysis of the relief and the results of the investigations of many years by the authors for this purpose are discussed in the article.
