Earth Science Careers: Critical Minerals

Economic Geology | Mining Geology

Background

According to the American Geosciences Institute, critical minerals are primarily non-fuel minerals or mineral resources that are essential to existing and developing alternative energy technologies that are of limited supply and at great risk for their supply chains to be disrupted. U.S. Federal agencies determine that any disruption or absence of these minerals could have significant consequences for national security. The “criticality” of a mineral changes with time as supply and society’s needs shift. Demands for critical minerals such as rare Earth elements (REEs) has increased in recent years with the growth of high-tech devices for personal and commercial use such as wind turbines, solar panels, electronics, and batteries.

Earth scientists are necessary to explore for, identify, and evaluate the economic potential of current and new mineral resources for each of the elements on the list.  

Current and Future Job Prospects

Earth scientists study the formation of critical minerals, explore for and locate them, plus help determine how to mine them economically, safely, and with minimal environmental impact. The world is slowly shifting its energy mix to one that is greener, but the transition will require significant mining resources. The demand for these resources has been propelled by rising demand and high prices, and the rapid growth is set to continue as some of these minerals are key to the energy transition. Employment is on pace to double by 2030. 

What Graduates Do

Field geologists observe geological features and study outcrops working outdoors and create maps and reports of their findings. They also monitor drilling activities and log drill cores or cuttings. Finally they work on active mines to assess ore quality on a real-time basis. Many mines are in remote locations and require the Earth scientist to live in a mining camp on a two-week on-two-week off basis. This is particularly true for mines outside the U.S.   A mining geologist should be comfortable traveling to and living in third-world countries. 

Resource geologists evaluate geological data to generate geologic models to identify resources and determine economic viability of projects.   

Degree expectation: The required education level for a job in critical minerals development or exploration depends on whether the opportunity is for an entry-level position or more senior-level opportunity. Most entry-level jobs will require a Bachelor’s degree in geological science, geological/geophysical engineering, or mining and mineral engineering. Job available to Bachelor’s graduates are almost entirely field-based and involve onsite analysis of core and other mineral data to determine ore content and quality both in an existing mine and in areas of potential mine development. Higher-level positions typically require a Master’s degree and research-based positions, both with private companies and government agencies, require a PhD.

Knowledge and Skills

Essential Knowledge and Skills: 

Preparation for a career in critical minerals as an Earth scientist can be obtained in an undergraduate major track with courses including—but not limited to—mineralogy, petrology, structural geology, geochemistry, geophysics, hydrogeology, ore deposit geology and field camp. Some roles may involve field geology skills and documenting geological surveys and programs. Depending on the country, region, or location you may also need to obtain a professional license from a recognized body, such as the American Institute of Professional Geologists (AIPG) or state certification entity.
