Mineralogical-technological features of the Primorskoe gold ore deposit are studied. It is established that ore minerals on the top of horizon make no more than 3%. Sulfide minerals and sulfosalt minerals of silver, excepting pyrite are sphalerite, galenite, chalcopyrite, acanthite, pyrargyrite, stephanite, freieslebenite, sternbergite Ц no more than 0,5%. Together with native gold there are electrum, kyustelite and silver registered. The study of ore minerals by the method of cyanidation showed that the ore is successfully extracted in solution with the content of 95-95% Au and 83-84% Ag as it, practically, does not contain harmful to cyanide process impurities.
