LARAMIE – The Wyoming State Geological Survey, in partnership with the U.S. Geological Survey will conduct a high-resolution airborne geophysical survey across portions of southeastern Wyoming beginning as soon as this week, part of a national effort to map the mineral resources needed for the U.S. economy and national security.

Focused on the Shirley Mountains and Hartville Uplift areas—regions known for mineralization but limited by existing geophysical data—the survey aims to improve understanding of subsurface geology and better target areas of critical mineral interest for future mapping and research.

“Baseline, high-quality geophysical data have become essential for modern geologic investigations,” said Erin Campbell, WSGS Director and Wyoming State Geologist. “These surveys help identify hidden structures and features that could point to valuable resources and guide ongoing research across Wyoming’s mineral-rich terrains.”

“WSGS is a key partner as the USGS leads national efforts to map the critical minerals needed to drive the U.S. economy and national security, and expand our knowledge of the nation’s geologic framework. Wyoming produced $622 million in nonfuel mineral commodities in 2024, eighth-most in the nation. Expanding knowledge of the state’s subsurface geology could grow the state’s mining sector,” said Jamey Jones, science coordinator of the USGS Earth Mapping Resources Initiative.

The survey will acquire both magnetic and radiometric data across two regions. The western block (Area B) includes Pathfinder Reservoir, the Shirley and Freezout mountains, and the western part of Casper Mountain. The eastern block (Area A) covers the Hartville Uplift, stretching from near Wheatland to north of Lusk.
