Abstract—This paper focuses on new data for palladium-bearing mineral phases in the ores of the Malmyzh porphyry gold–copper deposit situated approximately 220 km northeast of Khabarovsk in the Russian Far Eas. The Malmyzh area comprises the Early Cretaceous terrigenous sediments, which are intruded by the Albian to Cenomanian diorite and granodiorite stocks. The platinum group minerals (PGM), sopcheite, merenskyite, kotulskite, naldrettite, and arsenopalladinite, were identified during a detailed study of chalcopyrite veinlets at the Freedom site of the Malmyzh porphyry Cu–Au deposit. The relationship with other minerals indicates that these PGM are later than chalcopyrite.
