Thiess is the world’s largest contract miner, responsible for all mining activities in the CIMIC Group. This followed a strategic review in 2014 which streamlined the Group’s construction, mining and services operations, and established Thiess as a totally mining-focused business.

Flexible and scalable in our approach, our broad capabilities encompass:

- Mine planning
- Operations and technical services
- Continuous mining systems such as in-pit crushing and conveying systems
- Mobile plant management
- Product handling and processing
- Mine infrastructure.

Our international footprint now spans 24 mines across six countries with expertise in major commodities including:

- Metallurgical and thermal coal
- Iron ore
- Copper
- Nickel
- Gold
- Diamonds.

Our experience comes from working with a range of clients in different countries and with varying pit sizes, complexities and conditions. In 2014 alone, we mined more than 120 million tonnes of coal and iron ore and 413 million BCM of overburden across our operations.

We pioneered large-scale open-cut mining in Australia more than 70 years ago and today we blend that can-do spirit with cutting-edge technology and innovation to continually challenge and refine mine planning and operations to benefit of our clients.
