Deposit Type

  • Orogenic
  • Vein / narrow vein
  • Breccia pipe / Stockwork
  • Epithermal


Summary:

Both the Tulkubash and the Kyzyltash mineralisation are classified as orogenic gold deposits. The Tulkubash mineralisation exhibits characteristics of shallow epithermal mineralisation, and is further classified an epizonal orogenic deposit. The Kyzyltash mineralisation formed in a much deeper environment and is classified as mesothermal orogenic gold deposits.

The Chaarat Property, located within the Middle Tien Shan Province, locates within the Tien Shan Metallogenic Belt, a Hercynian fold and thrust belt that crosses Central Asia.

The Sandalash River valley down cuts a northeast-trending sequence of Cambro-Ordovician siliciclastic sediments which comprise the Chaarat Formation. This in turn is overthrust by a sequence of younger Devonian-age quartzites which make up the Tulkubash Formation. The sedimentary rocks hosting mineralisation strike north-easterly and exhibit dips between 40° and 75° to the northwest. Younger, Permo-Triassic-age granodiorite and diorite phases intrude the sediments and are closely associated with the gold mineralisation and, in some areas, are themselves mineralised.

Mineralisation and associated hydrothermal alteration at Chaarat are genetically associated with igneous intrusive rocks along a system of regional-scale, sinistral, oblique-slip faults. Within this setting, there are two distinct types of mineralisation: the Tulkubash-type and the Kyzyltash-type. However, the proximity of the two types of mineralisati ........

Summary:

The following associated overall slope geometry was recommended by WAI:
- Berm width: 5.5 m;
- Bench height: 15 m;
- Bench face angle: 66° and 75°;
- Inter-ramp angle: 51° and 58°; and
- Geotechnical berm: 9.5 m.

The bench face angles in the final designs vary between 60° and 75°, with 8 m berm widths to comply with local regulations and to allow mechanised cleaning. The inter-ramp angles (IRA) of around 51° and 58° for the various design sectors (i.e., Sectors 1 to 4), were flattened slightly to accommodate bench width and aligned with the WAI bench geometry recommendations. The IRA for the fault zone was reduced to 45°.

In the revised 2020 pit design it was noted that the final highwall reaches a height of 375 m, a moderate highwall height increase of approximately 1.4%.

The Tulkubash 2020 EOY open pit design is composed of three separate pits arranged along the strike of the orebody over 2 km. The pits are situated in steep, mountainous terrain at elevations of 2,300 masl to 2,800 masl. The deposit is divided up into two zones, the Main Zone and the Mid Zone.

The Main Zone Pit is situated at the southwestern end of the mining area. It is the single largest pit accounting for over 90% of the reserve by both tonnage and contained gold. The Main Zone Pit hosts a reserve of 19.4 Mt ore grading 0.86 g/t Au, containing 538 Koz Au. Associated with the ore is 50.4 Mt of waste resulting in a strip ratio of 2.6:1 ( ........
