Qualifications for technical jobs vary considerably. Learn about accredited degree programs, and certificate courses that you can take to advance your career. Mining techniques have dramatically transformed over many years, with technological advances improving efficiency and safety. In the discovery stage of mineral exploration, mining engineers work closely with geologists to identify minerals and assess reserve quantities. Mineral engineers may then drill core samples and conduct surface surveys, searching for specific compounds and ores. Unless the mineral exploration is done on public lands, the property owners may play a significant role in mining exploration.
