Summary:

Irtyshsky is an operating underground mine exploiting a polymetallic volcanogenic massive sulphide (VMS) deposit of average size and grade. The mineralisation is of lenses with extensive strike extents but more limited down-dip persistence. There are three principal ore bodies: Main, South East, No 2.

Irtyshsky Principal Orebodies:
Main:
- Orebody Strike length - 2,500 m;
- Down-dip length - 750 m;
- Thickness - 3.5 m.
South East:
- Orebody Strike length - 3,000 m;
- Down-dip length - 400 m;
- Thickness - 2.7 m.
No 2:
- Orebody Strike length - 1,600 m;
- Down-dip length - 300 m;
- Thickness - 1.35 m.

The orebodies pitch slightly to the NW with their long axes roughly parallel. The average strike of the Irtyshsky ore body is NW-SE and the dip of the ore body is steep to sub-vertical (70-80°). The ore body is gently folded with secondary thickening of the ore lenses in the fold axes. The copper and zinc grades increase with increasing depth from surface.
