The Mangazeisky Property contains two main deposit types: epigenetic polymetallic silver-lead-zinc veins (metasediment hosted), and porphyry (copper, gold, silver). The majority of the exploration, and the existing resources, are focused upon the polymetallic silver-leadzinc veins. The veins are sulphide-rich, containing sphalerite, galena, silver, and sulphosalt minerals in a carbonate and quartz gangue.
The Property contains several explored areas that host more than 100 occurrences of mineralisation. The mineral occurrences are concentrated within a 35-km long corridor. These main mineralised areas include: Yasny, Burny, Mukhalkansky, Zabyty, Zabyty-2, Mangazeisky, Strezhevoy, Vertikalny, Porfirovy-Borisovsky, Vostochny, Nizhny Endybal (NizhneEndybal), VerkhneEndybal, Jilny, Bezymyanny, Orogondia and Kis-Kue.
The mineralization of Mangazeisky North is mainly associated with banded brecciated textures. The following minerals are present: Native silver, acanthite, stephanite, polybasite, canfieldite, pyrargyrite, miargyrite, diaphorite, tetrahedrite, owyheeite, freieslebenite, boulangerite, arsenopyrite, sphalerite, pyrite, galena and chalcopyrite. The veins are strata-bound, occurring on contacts between strata, particularly around sandstone units, and tend to be dilated towards the hinge of the local fold structure. It is noted that the strongest silver mineralisation occurs within the central core of the veins, this also correlates with the zones of ........
