About us

#About us

Thiess works with clients in Australia, Asia and the Americas in the dynamic field of open-cut and underground mining.

#

At our core is the pioneering spirit of the legendary Thiess brothers. Their vision defined firsts, unlocked possibilities and found smarter ways to scale what mattered to society. More than 85 years on, their story is still in our DNA.

We’ve always thrived amid change. Today, that includes rising to the challenges of climate risk and the opportunities abounding in the global energy transition. We recognise the world needs mined commodities to achieve the economic, social and environmental transformation it desires. That’s why the world needs mining…reset for the future.

#A sustainable future

Thiess is embarking on our most exciting transition yet – a transition to a sustainable future. From new ways of working to plant and equipment innovations to technical advancements. We’re refocusing our skills to create pathways for rapid, responsible transitions to lower-emission mining. We’re channelling our global insight to create local advantages for each project; developing optimised solutions to each client’s goals and ensuring certainty of delivery in each context. And we’re diversifying our commodities and services to support the energy transition and enhance social and environmental value as we grow.
