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.
