- This $427,699 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research to improve the understanding of how copper accumulates in significant concentrations, particularly in porphyry copper deposits. The project will test models of porphyry copper deposit formation by studying deposits in Sonora, Mexico, and develop geochemical tools to aid in the discovery of new copper deposits. The research will also train a Latino early-career scientist, a...
- This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $270,013 to the University of Nevada, Las Vegas (UNLV) to investigate the processes that concentrate critical metals in porphyry copper deposits. The principal objectives are to assess the spatial and temporal variation in ore-forming processes, with a focus on using pyrite as a recorder of changes in metal sources and fluid compositions. The research team, which includes graduate and...
- The National Science Foundation (NSF) Division of Earth Sciences awarded a $444,296 project grant to the Regents of the University of Michigan (University of Michigan) to conduct collaborative research on improving the understanding of how two types of copper ore deposits form and developing methods to find undiscovered deposits. The grant, funded under the Geosciences program (CFDA 47.050), will support a graduate student and several undergraduates in mapping, logging, sampling, and...
- This Project Grant award from the National Science Foundation (NSF) Division of Earth Sciences (CFDA 47.050 - Geosciences) provides $114,133 to Juniata College to conduct collaborative research on the source of mineralizing fluids in iron oxide-copper-gold (IOCG) mineral deposits. The key objectives are to improve understanding of how different types of copper ore deposits form and develop methods to locate undiscovered deposits. The research will compare the multi-element isotopic signatures of...
- The National Science Foundation Office of Integrative Activities awarded the Regents of the University of Minnesota $403,841 on July 1, 2026, under the Geosciences program (CFDA 47.050) to investigate iron isotope fractionation in seafloor hydrothermal fluids and minerals from the Juan de Fuca Ridge. The recipient will conduct iron isotope analyses on time-series hydrothermal vent fluids and co-precipitated mineral samples acquired in collaboration with Ocean Networks Canada, complemented by...
- Federal Grant Award Summary The National Science Foundation's Division of Polar Programs (CFDA 47.078) awarded Colorado School of Mines a $200,000 Project Grant effective September 1, 2025, through August 31, 2027, to conduct planning activities for a comprehensive study on undersea critical mineral mining in the Arctic. This planning project will identify high-priority research questions, assess feasibility for future longitudinal and interdisciplinary research, and establish a...
The National Science Foundation Office of Integrative Activities awarded the Trustees of the Colorado School of Mines $403,266 on August 1, 2026, to quantify copper-iron isotope fractionation and redox partitioning in sulfide leaching of critical minerals under the Geosciences program (CFDA 47.050). The project develops isotope-based chemical fingerprints to reveal when and why copper release is limited during sulfide leaching, enabling more efficient recovery of copper from already-mined material and reducing pressure to open new mines while strengthening domestic mineral supply. The same tools will provide information about metal movement in legacy mine drainage systems. The work employs bench-scale flow-through columns to leach single-sulfide and mixed-sulfide materials across controlled gradients in pH, redox potential, and ligand chemistry. Time-resolved leachates will be analyzed for copper and iron isotopic composition and major-element concentrations, while reacted solids will be characterized chemically and mineralogically to connect isotope signals to mineral-surface transformations. Field transects at legacy hardrock mine sites, including Summitville, Colorado, will test whether laboratory-derived fractionation factors and passivation thresholds apply in chemically heterogeneous drainage environments. The fellowship will provide training opportunities for the postdoctoral fellow and undergraduate researchers. Performance occurs in Golden, Colorado, with a period of performance from August 1, 2026, through July 31, 2028. The funding is obligated as $403,266.
