About us
At Tercienco, we believe that Earth’s natural resources should be – and can be – unlocked and managed in a responsible and sustainable way.
Tercienco BV is a privately-owned, independent geological consulting company established since 2013.
We offer a range of geological services to various types of stakeholders in the mineral industry, including mining and mineral exploration companies, government and non-governmental organisations, and companies in the end-use market for natural minerals and metals.
Our staff are all members of the European Federation of Geologists (EFG) and are dedicated to maintaining the highest professional ethical and environmental standards.
We are based in Belgium but have worked on many projects across the globe, in sedimentary, metamorphic and magmatic geological environments and both in grassroot and brownfield operational settings.
