The large Malmyzh gold-copper porphyry deposit was discovered as a result of exploration conducted by Amur Minerals LLC between 2007 and 2015. In April 2015, the Russian State Commission on Mineral Reserves (GKZ Rosnedra) approved copper and gold reserves in categories C1 + C2 as follows: ore – 1.39 billion tonnes; copper – 5.6 million tonnes, with an average grade of 0.41%; gold – 298 tonnes, with an average grade of 0.21 g/t. In 2018, the Russian Copper Company JSC acquired 100% of the shares in Amur Minerals LLC, the operator of the deposit.
The geology of the Malmyzh deposit consists of Lower Cretaceous terrigenous sediments intruded by diorite to granodiorite intrusive rocks. The ore-hosting rocks are overlain by loose Quaternary sediments.
The gold-copper mineralization is spatially associated with porphyrite stocks and occurs as mineralized stockworks overprinting metasomatic zones of two main types: magnetite-sulfide (predominantly copper) and quartz-sulfide (gold-copper). The Malmyzh gold-copper porphyry system is considered a single large deposit, within which zones of varying mineralization intensity are distinguished. These zones range in size from 0.2 km² to 4 km². The area of the ore-bearing stockworks varies from several hundred square meters to 1.8 km². The deposit includes four major ore zones (Central, Ravnina, Valley, and Svoboda) and ten smaller ones (Northern, Western, Bikha, ABV, Fate, Udel, Sharga, Stockwork, Volkov-1, and Volkov-2), located either on the periphery of the major zones or filling the spaces between them.
