Deposit Type

  • VMS


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.


Mining Methods

  • Sub-level caving
  • Shrinkage stoping
  • Room-and-pillar


Summary:

Labour intensive shrinkage stoping is used with high ore dilution (32%). Some sublevel caving and room and pillar mining is also conducted. Jackleg drills and slushers are used for mining with rail haulage to the ore pass leading to a jaw crusher. Hoisting in a 650 m deep shaft is conducted with 10 t skips.
