Maleevsky is a typical syngenetic VMS deposit hosting ores of sulphide-polymetallic formation with associated gold and silver.

The Maleevskoye deposit comprises seven stratabound zones of lead-zinc-copper-gold-silver mineralisation: Rodnikovaya, Maleevskaya, Octyabrskaya, Holodnaya, Lugovaya, Bobrovskaya and Platovskaya. The stratabound bodies generally strike 300-310°, parallel to axial traces of the domes, dip at low to moderate angles SW and plunge NW.

Mineralisation is divided into polymetallic (lead-zinc with >0.6% Pb) and copper-zinc (<0.6% Pb and high Cu), the division defined by the lead content. In general, polymetallic mineralisation, accompanied by barite, occurs on the flanks and on the hangingwall side of the lenses, whilst copper-zinc mineralisation tends to prevail in the central parts of the lenses and on the footwall side. The largest and richest mineralised zones (Maleevskaya, Rodnikovaya, Holodnaya and Lugovaya) occur within a 150-200m thick Maleevskoye Member of the Maslovskaya Formation. They consist of massive sulphide stratabound bodies of various forms (saddles, lenses, tabular bodies) which pass downwards into veinletdisseminated mineralisation.

Maleevskaya Zone
A series of folded stratabound lenses of complicated geometry has subsequently been traced to a depth of 700-750m. The overall strike of the zone is 315° with a 32-35° northwestern plunge. The combined strike length is 2.3km. The largest mineralised body in this zone, identified as No 3 Orebody, has a strike length of 1,175m and extends from Level 4 (430m) down to Level 16 (-170m). Its larger north¬western segment measures 575m in strike length with a down-dip extent of up to 250m. Dips are highly variable but generally less than 40 ° SW flattening and turning NE at the north¬western end. The southeastern part is about 410m in strike length and extends down-dip for up to 195m. The average dip is 20-25 ° SW.

Rodnikovaya Zone
This is the main mineralized zone at the Maleevskoye deposit. It extends from Level 9 at 180m down to Level - 550m along a dome structure plunging 25-30 ° northwest. The total strike length is 1,750m.

Bobrovskaya Zone
This zone is situated southwest of the Rodnikovaya Zone at a depth of 1,000-1,500m below the surface. It contains at least three lenticular bodies over a strike length of 1,750m.

Octyabrskaya Zone
The strike length is 600m. Mineralised bodies forming this zone dip west and northwest.

Holodnaya Zone
This is the deepest zone so far discovered at the Maleevskoye deposit. It is situated at a depth of 1,400- 1,700m, 2km from the central part of the Rodnikovaya Zone.

Platovskaya Zone
This zone occurs within a NNW trending subsidiary situated in the northeastern part of the deposit, 700m from the Maleevskaya Zone. It extends over a vertical distance of about 120m with widths in the range of 5.5m to 23m (6m on average). The lode plunges 20° NW.

The Ridder-Sokolny deposit is a unique deposit that has characteristics of several deposit styles. The total footprint of the mineralisation exceeds 20km2. The upper ore zone of the deposit consists of a cluster of sub- horizontal VMS-style lens-shaped bodies associated with a carbonaceous unit adjacent to a vertical fault structure. The lenticular VMS-style mineralisation is underlain by a steeply dipping to sub-vertical polymetallic Cu- rich stringerstockwork ore zone. Structurally controlled gold-bearing quartz veins overprint the entire system.

Tishinsky is a syngenetic VMS deposit hosting ores of sulphide-polymetallic formation with associated gold and silver.

Dolinnoe and Obruchevskoe
The Dolinnoe and Obruchevskoe deposits are located in the Leninogorskaya graben/syncline, which is constrained to the north by an overthrust, to the south by the Obruchevskoe upthrust fault and to the east and west by the marginal Uspensko-Karelinskaya and Kedrovsko-Butachikhinskaya shear zones.

In the graben/syncline mineralised deposits with a shallow dip, plunge at 7-10° to the south, south-east and south-west from the Ridder-Sokolniy ore deposit in conjunction with the trace of the upper contacts of the Kryukovskaya and Zavodskaya suites. Gently dipping fold structures (striking north-east) can be identified viz. an anticline to the north with the associated deposits of Ridder-Sokolniy and Bakhrushinsk, and a southern plunge associated with the Novo-Leninogorskoye and Obruchevskoe deposits separated by the Central syncline.

In the central area of Dolinnoe synclinal folds with an amplitude of 400-600m are evident and to the northeast, and south-west anticlinal structures are developed complicated by discontinuous curved and longitudinal faults with downthrows to the south west of 95-160m and up to 130m respectively. The longitudinal faults also exhibit lateral movement of up to 95m.

The Obruchevskoe deposit is located on the plunging southern limb of the southern anticline where low angle thrusts with a north western strike occur. Faulting is not evident in the ore zones of the Obruchevskoe deposit.

The Vasilkovskoye deposit belongs to the group of intruded-related Au deposits. It is located in the western part of the Shatskaya metaliogenic zone of the North Kazakhstan province, with a northwest trend.

The mineralisation at Vasilkovsky gold deposit is spatially associated with a stockwork of hydrothermal quartzarsenopyrite veins. The main mineralised structures comprise gold-quartz-dominated veins locally merged on stockwork/breccia zones.
