After a year working at an underground copper/gold mine in Australia, he joined Billiton and moved to Suriname, where he worked in bauxite mine operations. He obtained his MBA from Rotterdam University in 1994 and moved to Ghana, where he worked at gold mines for Ashanti (now AngloGold Ashanti). From 2000 to 2004, he worked at a Kenyan ruby quarry, a manganese mine in Ghana, and on a dredging project in Sri Lanka. In 2004, Marco moved back to Suriname, where he spent five years with BHP Billiton as manager of the Lelydorp mine and mine manager for the Bakhuis project.
