They are accompanied by studies of fractions in which we study minerals, their chemical composition and a set of trace elements.
In parallel with schlich sampled on geochemical and specialized studies. In order to identify the intermediate reservoir and evaluation of their role in nutrition placers held lithofacies study of thick clastic (mostly psephytic and mixed) of loose rocks of various ages and origins. Such thick anterior clearance boreholes. Of these horizons are selected schlich, samples, which are detailed mineralogical, geochemical and specialized studies.
To assess the gravel excavation sites used pits and drilling of a system of profiles crossing the promising areas at all levels of erosion and accumulation of the valleys. From mine workings over an interval selected schlich sample. We also have geochemical and specialized testing. Schlich testing is accompanied by geophysical observations - microseismic studies, the exact magnetic survey.
