The new Samolazovskoye gold deposit (Central Aldan, Yakutia) is intensively developed by heap leaching. The loose oxidized ores with very fine free gold, with the practical absence of clay minerals, provide a high efficiency of their processing. The very small size of the goldtins and identified in the fine fraction skarn mineral - richterite confirm the idea of the primary source of the metal - it is the surrounding industrial deposit weakly gold-bearing sulfidized skarns. Due to their oxidation the concentration of gold occurred to the level of industrial grades.
