FIELD: geotechnology. SUBSTANCE: method may be used for in-situ leaching of gold from the bed of permafrost gold-bearing sands. To do it, boreholes are drilled through monolith of cap rock, and into the latter solutions of sodium oxychloride and stabilizing additives (magnesium sulfate, sodium silicate, boric acid, sulfuric acid, etc.) are fed. EFFECT: facilitated metal leaching process.
