Artemyevsky is located 47 km SE and 10 km NW of the Orlovsky and Nikolayevsky Cu-Zn deposits respectively, 10 km SW of the town of Shemonaikha and is one of the large volcanic hosted massive sulphide deposits of the Rudny Altay Volcanic Arc of eastern Kazakhstan. The deposit, which commenced operation in 2006, is ~125 km WNW of Ridder, ~110 km ENE of Semey, and 18 km south of the Russian border (#Location: 50° 35' 43"N, 81° 47' 13"E).
For details of the Rudny Altay Volcanic Arc, see the Orlova record.
The Artemyevsky deposit comprises a number of different, steeply dipping orebodies, the largest of which is the Main Orebody, which has a strike length of 1300 m and maximum thickness of 200 m. The higher grade, but less continuous Talovskaya Orebody is 50 to 150 m in the footwall of the Main Orebody, while the shallow Kamishinskaya Orebody occurs closer to the surgface, above the Main Orebody. Six other orebodies occur as a series of sub-parallel lenses, diping gently to the east of the Main and Talovskaya orebodies.
There is a vertical zonation through the individual orebodies, from barite-polymetallic at the top, to polymetallic to copper-zinc to copper ores at the base. Copper-rich zones of mineralisation are found below the orebodies in the lower parts of the host Talovka formation.
Regionally, the the Middle Devonian host Talovka formation is composed of mainly 'quartz-albitophyre', their lava-breccia, tuffs and tuffites, and lesser sediments. The Talovka formation overlies a succession of cherty clay-siltstones with bands of 'quartz-albitophyre', tuffaceous sandstone, tuffites and sandstones of the Berezovo Group, and is overlain by Upper Devonian, siltstone, limestone, conglomerate, acid to intermediate volcanics and sandstones;
