Thiess Group Holdings Pty Ltd

What Thiess Group Holdings Pty Ltd does

Thiess Group Holdings Pty Ltd is the world's largest mining services provider, with 90+ years of operating history since its 1935 founding. The company delivers an integrated suite of mining services to enterprise clients across the full mine lifecycle, organized around six core offerings: Asset Services (equipment maintenance and fleet management), Autonomy (autonomous hauling and drilling via Cat MineStar Command on private LTE networks), Engineering (mine planning and technical design), Extraction (drill and blast, load and haul), Rehabilitation (mine closure and land restoration), and Enabling Services (environmental, water, and community management). These capabilities are deployed across open-cut and underground operations in coal, copper, lithium, nickel, gold, and iron ore.

The business model is full-service mining contracting, secured through competitive tendering and structured as mine-life agreements, multi-year contracts, or schedule-of-rates arrangements with major resource companies. Notable clients include BHP (BMA and Nickel West), Glencore, Anglo American, Harmony, Pembroke Resources, Bayan Resources, Wesfarmers/SQM JV (Covalent Lithium), QCoal, OceanaGold, Coronado, Jellinbah Group, and Austral Resources. Revenue is not publicly disclosed. Disclosed individual contracts range from A$112 million to A$700 million, including the Eva Copper alliance (A$700M), Wahana extensions (A$480M combined), Peak Downs/Caval Ridge ($440M), Wahana renewal (A$220M), Jellinbah Plains extension ($189M), and Prominent Hill (A$112M). Operational footprint spans Australia, Indonesia, Mongolia, India, Singapore, the USA, Canada, and Chile.

Thiess is a private company and wholly-owned subsidiary of Cimic Group (controlled by Germany's Hochtief) following Cimic's July 2026 A$1.18 billion re-acquisition of the remaining shares from Elliott Advisors-advised funds. The company differentiates through scale (world's largest), proprietary autonomous mining deployments (world-first simultaneous autonomous haul and drill at Olive Downs), ownership of large specialized fleets (Liebherr, Caterpillar), and a deliberate pivot into critical minerals tied to energy transition supply chains. Strategic partnerships include Toyota (hydrogen generators for decarbonisation) and Covalent Lithium (Mount Holland).
