Samples of oxidation zone of the Elenovskoe Cu porphyry deposit are studied using optical and scanning electronic microscopy. In addition to Fe hydroxides and abundant malachite, the supergene mineral assemblage includes native Cu and Au, Ag-containing covellite, cuprite, tenorite, plumbogummite, goyazite, iodargyrite, atacamite, and chrysocolla. The oxidized ores contains pyrite relics and high amount of tourmaline (dravite). Some dravite grains contain Cu.

Figures 3. Tables 8. References 35.

Key words: Elenovskoe deposit, cuprous gold, supergene minerals, Bronze Age metallurgy, tourmaline.
