A Shallow to Deep View Inside the Hydrothermally Altered and Mineralized Silverton Caldera Complex: New Geologic Insights Gained From Modern Geophysical Interpretations

The Silverton caldera complex in southwest Colorado hosts base and precious metals that have been mined since the late 1800s. Extensive mine workings, excellent bedrock exposures, and deeply incised drainages make this area a natural laboratory ideally suited for furthering our understanding of the mineral systems in a volcanic environment. In addition, state-of-the-art geophysical...

Critical Mineral Recovery Potential from Tailings and Other Mine Waste Streams

The primary objectives of this one-year scoping project are to determine the feasibility of extracting byproduct mineral commodities, such as critical minerals, from mine tailings. We plan to analyze the existing data and reports from an active mine site on the composition of their mill tailings pile, and collect preliminary reconnaissance samples to identify appropriate analytical techniques...

Volcanic-related Beryllium Deposits of the US: Geologic Setting, Genesis, and the Potential for Post-Extraction Recovery of By-Product Critical Minerals

Project objectives are: 1) to fully establish a comprehensive and robust geologic and geochemical framework for the occurrence of volcanic-related beryllium (Be) deposits; 2) further our understanding of the fundamental ore processes that lead to formation of volcanogenic beryllium (Be)-boron (B)-lithium (Li)-phosphorus (P) group deposits, by investigating processes favorable for enhanced...

Geochemical Signatures and Environmental Impacts of Ore and Trace Mineralization in the Southern Midcontinent

The overall project objective is a comprehensive analysis of the natural and anthropogenic consequences of extensive ore and trace mineralization in the southern midcontinent of the U.S. with a focus on Missouri. This will be conducted at two scales: 1) landscape and 2) process-level.

1) Landscape scale using geospatial and machine learning techniques to combine multiple geochemical and...

Emerging Geoenvironmental Issues Related to Proposed Mining in the Lake Superior Region

We are studying environmental issues related to mining, and potential mining, in the Great Lakes region, continuing the study of characterizing baseline geochemistry of several watersheds in Minnesota and Michigan, examining the potential for aquatic toxicity from metals, and examining the acid-neutralizing and acid-generating potentials of mine waste, and the environmental, and possible human...

Beryllium: Economic Geology, Material Flow, and Global Importance of a Key Critical Mineral

Beryllium (Be) is a critical metal mineral commodity with unique chemical properties, making it indispensable to the computer, telecommunication, aerospace, medical, defense, and nuclear industries. We are studying known deposits of beryllium to determine where undiscovered beryllium resources might be found, analyzing how and where beryllium becomes concentrated in Earth’s crust, gathering a...
