Einar Rossmann – Dipl. Geo

Einar has 24 years of experience in the mining industry and consulting. After two masters in applied geology (Germany and France) he started his working life in France in a drilling company and then moved to the coal mining industry in Germany. Since then, he has held various positions in the mining cycle, from exploration to extraction and mine closure in different countries and continents, and due to his linguistic qualifications, he has also worked in many francophone countries. Many of these functions also required strong project management skills. A highlight was the work in the area of conflict minerals certification in the eastern DRC and the position as COO of a major iron ore project in Liberia. He has always had a special interest in small-scale mining, which he first encountered during his studies on a trip to French Guiana and Suriname.
