Mark is an independent scientific consultant in the Australian mining and metallurgical industries, with specific major expertise in radiation management in uranium, mineral sands, and (over the last 5 years) rare earths exploration, mining, and processing. His background in asteroid exploitation began as a visiting scholar at the University of Arizona Lunar and Planetary Laboratory where he examined the technical and economic feasibility of mining near-Earth asteroids. Then the Foundation for International Non-Governmental Development of Space (FINDS) funded Mark to extend this research, and to prepare and test cometary crust simulant material. Resulting papers were accepted and presented at several scientific forums.
