Thiess’ record of delivering excellence at the Oyu Tolgoi (OT) copper mine in Mongolia is continuing as the team executes the recent contract extension at the project through the company’s longstanding joint venture, Thiess Khishig Arvin (TKAJV).

The Thiess team of 120, including 75 new hires, has safely and successfully completed almost 50% of the planned extension works. This includes building a:

  • 6.4 km concrete conveyor decline (6 m-wide and 150 mm thick).
  • Change/locker house with a capacity of 100 lockers for personnel to work for future projects.
  • An 80-man refuge chamber at UG stockpile 24 with compressed air system, painting whitewash on wall and epoxy resin on floor.

In 2021, the team delivered a significant milestone at the boxcut and decline project , achieving the final breakthrough in the conveyor decline tunnel, connecting the C2S conveyor to surface tunnel to the existing OT underground mine.

This achievement was underpinned by a safety achievement of 3-million-man hours with no lost time injuries.

This year marks 15 years since the Thiess team began operations in Mongolia, bringing with it a commitment to working with clients to deliver excellence, creating a strong safety culture, contributing to community and building and strengthening the national workforce.
