As geochemical studies on the area of permafrost spreading show, even for ore bodies entirely located in the frozen rock zone, liquid or salt scattering halos are detected on the day surface, which are related to these bodies by origin.

Solubility of gold in solutions of various inorganic compounds has been studied by many researchers. Experiments have been conducted with metallic gold in the form of plates, wire, powder and with thin films of gold on glass. Gold dissolves usually under the action of strong oxidizing reagents, such as free chlorine (its action explains the good solubility of gold in vapor vodka).
