Abstract

The article presents the results of studies of the mineralogy of the ores of the poorly studied gold-antimony Krokhalinoye deposit (dyke type), located on the southeastern flank of the Yana-Kolyma orogenic belt. Sulfide mineralization is represented mainly by stibnite, arsenopyrite and pyrite, less often jamesonite and berthierite are noted; of the gold minerals, high-fineness native gold, aurostibite, electrum and "mustard" gold (auroantimonate) are present. The native gold of the deposit is the highest-fineness of all known deposits of the Central Kolyma region.
