Andreas studied geology and paleontology at the Johann Wolfgang von Goethe University in Frankfurt, and mining geology at the Technical University of Clausthal, Germany. He graduated with a thesis on a sediment-hosted uranium deposit in Arizona, and with a structural mapping project on a Zn-Pb-Ba Sedex deposit in Germany. He then joined St. Joe Explorations GmbH working as a project geologist for Kupferschiefer-type Cu-Ag mineralization. Subsequent employment with Schlumberger Middle East S.A. led to a position as Senior Field Engineer for drill hole geophysical logging and wire-line services in offshore oil and gas fields, Abu Dhabi. In 1990, Andreas completed a Ph.D. study in economic geology at the University of Western Australia with a thesis on Archean gold deposits in the Yilgarn Craton emphasizing gold skarns. After a postdoctoral fellowship at Stanford University, California, he returned to Western Australia working as a consultant for various mining companies, mainly Placer Dome Asia Pacific prior to their takeover by Barrick Gold.
