(left to right) PhD candidate Gabriel Ahrendt, undergraduate researcher Miah Mol, and MS student Samuel Jensen from the Earth and Environmental Magnetism research group are gearing up our drone-based geophysics platform for its next test flight.

The Department of Geological and Mining Engineering and Sciences (GMES) at Michigan Technological University is always looking for opportunities to expand our education and research into new, forward-looking areas. Drone-based geophysics is one such area—an emerging field that is rapidly transforming how we investigate and understand the subsurface.

Drone-based geophysics offers remarkable potential for geoscience and engineering practice. By
combining unmanned aerial systems with advanced geophysical sensors, we can safely and efficiently
collect high-resolution data in challenging or previously inaccessible environments. These capabilities
are reshaping mineral exploration, environmental assessment, hazard mapping, and infrastructure
monitoring.

To provide our students with this increasingly sought-after skill set — valued across industry, government agencies, and research organizations — we have launched the development of a new drone-based geophysics curriculum. To support this initiative, the department has acquired a high-capacity Aurelia X6 Pro V2 drone paired with a Geometrics MagArrow II magnetometer, one of the most advanced airborne magnetic systems available. This effort is currently led by Professor Aleksey Smirnov, chair of GMES, together with MS student Samuel Jensen. Both have recently completed comprehensive training and earned professional unmanned aerial vehicle pilot licenses, ensuring safe and compliant deployment of these systems in research and instructional settings.

Sam Jensen and Aleksey Smirnov prepare a drone for its first outdoor flight, with tall trees in the background.
Sam Jensen and Aleksey Smirnov are preparing for the first flight of the Aurelia X6 Pro drone equipped with the Geometrics MagArrow II magnetometer.

Our vision is to develop a suite of drone-based geophysics courses covering not only airborne data acquisition but also advanced data processing and visualization. Students will use the state-of-the-art Seequent Oasis Montaj geophysical software — recently acquired to support the Applied Geophysics program — to work with real flight datasets, learn industry-standard workflows, and build strong practical expertise.

Our future research directions include a wide range of potential applications, such as high-resolution magnetic mapping of Precambrian rocks in the Upper Peninsula of Michigan, critical minerals and geological hydrogen exploration, surveys of mine tailings and legacy mining landscapes for environmental and safety assessments, geologic mapping of fault zones and structural features, and magnetic mapping for archaeological investigations.

We are also actively seeking collaborations with other departments and research centers at Michigan Tech, as well as partners outside the university, to broaden the impact and interdisciplinary reach of this developing program.

Looking ahead, we plan to expand our toolkit with additional drone-compatible geophysical methods, including electromagnetics and ground-penetrating radar, further enhancing opportunities for education and research.

We are excited about the hands-on learning and research possibilities that drone-based geophysics will offer, and we hope that this work will inspire more students to join GMES and contribute to the continued success of the department. Stay tuned for updates…

Preserving Historic Copper Mining Records

Published

Boxes of historical data ready to join the digital era.

Preserving historic copper mining records is at the heart of an exciting new project at Michigan Tech! Led by James DeGraff, GMES Research Professor, a team of researchers has secured $118,898 in matching grant funding from the National Park Service (NPS) to archive records through advanced digitization.

Titled “Preservation, Indexing, and Enhanced Utility of Historic Copper Mining Drill Hole Records,” the project is part of the NPS Save America’s Treasures Grant Program, which is dedicated to safeguarding the nation’s cultural heritage. Established in 1988 to celebrate America’s premier cultural resources, Save America’s Treasures grants this year funded 59 projects through the Historic Preservation Fund that will preserve nationally significant sites and historical collections in 26 states and the District of Columbia.

The team will digitize and organize records from over 650 drill holes from 1899 to 1970, creating an interactive map that will be accessible to the public. Copper mining on the Keweenaw Peninsula dates back more than 8,000 years, but an influx of miners in the 1800s—spurred by technological advances and rising demand for copper—made the region a hotbed of activity.

Congratulations to DeGraff and his co-investigators—Lindsay Hiltunen (VPOL), Don Lafreniere (SS/GRF), and Erika Vye (GLRC)—on this impactful initiative! The copper mining records hold significant historical and scientific value. They showcase the evolution of drilling technology and geology while contributing to current efforts to secure critical minerals from domestic sources.
