The taiga region, in which the features of water migration of gold and other ore elements were studied, is characterized by flat, weakly articulated relief, deep seasonal freezing of soil-cover deposits and wide development of upper bogs.
One of the main reasons for changes in the chemical composition of groundwater during drainage of developed deposits is the intensification of the overflow of pressure, more mineralized water of deep horizons, or squeezing (due to the growth of intra-class stresses) pore water from weakly permeable layers and blocks with a general decrease in head in the upper aquifers.
