KAZ Minerals International DMCC operates Bozymchak copper-gold mine in Kyrgyzstan.
KAZ Minerals Bozymchak LLC is a wholly-owned subsidiary of KAZ Minerals.
The Bozymchak deposits were generated by intrusion of a large granitoid stock with pinkish-grey porphyritic granites of the Dzhalgyzuriuk massif into carbonate cauntry rocks of Devonian and Carboniferous age. Devonian sediments are polymict clastics, calcareus sandstones and limestones of Frasnian-Famennian age. Carboniferous sediments are sandstones and limestones, sometimes siliceous and bituminous, of Tournaisian-Visean age and pyroclastic sedimentary rocks (andesitic and dacitic tuffs) of mid- Carboniferous age.Mineralization is generally in skarn zones, in the form of disseminated sulphides with associated gold. The major sulphide component is chalcopyrite with lesser bornite and covellite; there is some rare presence of sphalerite and arsenopyrite. Surface oxide mineralization is only weakly developed and is primarily marked by the occurrence of malachite. The skarn mineralization is of garnet-wollastonite and garnet-pyroxene types; metamorphosis of limestone and dolomite has occurred locally to form marble and siliceous limestone. The thickness of the skarn horizon varies from a minimum of around 7 m up to 85 m.To the east of the main central deposit sulphide zones are found which contain chalcopyrite, pyrite and pyrrhotite, with, in this zone, serpentinites which are the products of alteration of pyroxenite; some fibrous asbestos is also found. The Bozymchak deposit comprises four sectors separated as discrete areas by faulting: - South-western sector;- Central sector;- Eastern sector;- Davan sector.In the Central sector the skarn horizon occurs along a bow-shaped strike along the contact of country rock and the intrusion, along a 2 km strike with dip to the south of between 75-86 degrees.
