The theoretical and practical possibility of prospecting for gold occurrences on the basis of direct hydrogeochemical indicators - direct detection of gold in certain quantities in the waters.

Involvement of mathematical methods is increasingly used in hydrogeochemistry. The most widespread is mathematical statistics, which is used to solve a variety of problems, in particular, to determine the strength and nature of the relationship between the features, as well as the degree of influence of individual factors in the formation of the chemical composition of waters.
