Our company

We act on behalf of our clients worldwide with a wealth of experience in the fields of mining, energy, environment and infrastructure. Together with our associated companies, our 170 engineers and specialists within the G.E.O.S. group bundle a wealth of knowledge that is unparalleled in Germany and an outstanding innovative strength in geological, process engineering and the energy industry.



Our history – the cornerstone of our success

Today we operate as an independent medium-sized planning and consulting company, but our roots go back to the 19th century: The Geological Survey of Saxony, founded in 1872, and later the publicly owned company Geological Research and Exploration Freiberg, both laid the basis for our re-establishment on 1 May 1990.


We open up perspectives

Then and now, our expertise is focused on issues of raw material and deposit management and on geological and geotechnical services. We are growing with new challenges: G.E.O.S. is always the right partner for future-oriented topics such as energy infrastructure projects in the context of the energy transition or probabilistic modelling. In addition, we take care of the management of your projects and remove all obstacles through professional approval management.


We make sure,
that you will look at geological aspects and challenges with different eyes.

Our Management Board

Our management is the key contact for customers and employees. Flat hierarchies and direct communication channels allow us to act and decide in a flexible manner. This allows us, together with our employees, to respond individually to the requirements of our customers.
