Critical Mineral Research
A multi-agency research collaboration advancing the understanding of concealed porphyry copper systems and critical minerals in Arizona.
Advancing Critical Mineral Understanding
Overview
Bell Copper’s Big Sandy Project is the focus of a collaborative research initiative involving U.S. government agencies, state organizations, and leading academic institutions. This work supports the advancement of geological models, mineral system understanding, and exploration techniques for concealed porphyry systems in Arizona.
Contributing Organizations
COLLABORATION
Organizational Contributions
U.S Geological Survey (USGS)
Primary organizer of Arizona’s critical minerals research initiative, contributing geologic and geochemical data through the Earth Mapping Resources Initiative (Earth MRI) to advance domestic resource assessment.
Arizona Geological Survey (AZGS)
Leads the research program and project execution through integrated geological, geochemical, and geochronological studies evaluating Arizona porphyry systems, with the initiative developed by Dr. Carson Richardson and supported by USGS and the State of Arizona.
University of Arizona - Department of Geosciences
Collaborates on advanced research applying mineralogical, geochemical, and geochronological methods to characterize porphyry systems and assess critical mineral distribution, including graduate work by Jonothan Chappell linking Big Sandy and Diamond Joe, and doctoral research by Ms. Zoey Plonka on leached cap development and supergene enrichment.
Arizona Geological Society (AGS)
Supports the critical mineral research study by promoting industry engagement and sharing findings through technical meetings, publications, and a field trip to the Big Sandy project with an accompanying field guide.
Arizona State Government
Participates through statewide geological initiatives aligned with resource assessment and scientific research priorities.
PROJECT ROLE
Bell Copper’s Contribution
Bell Copper discovered the Big Sandy porphyry copper system and serves as project operator and data provider, contributing drill core (including BS-3) and geological data to the research program.
This collaboration provides access to a large, concealed porphyry copper–molybdenum system and supports research into critical minerals—including copper, molybdenum, rhenium, and silver—enabling real-world model validation.

KEY FINDINGS
Scientific Results
& Insights
Findings from the multi-agency and government research program include:
Recognition as a High-Priority System
Big Sandy was selected as one of the first porphyry systems in Arizona for detailed government-supported study, reflecting early recognition of its significance within U.S. critical mineral research initiatives.
Confirmation of a Large-Scale, Mineralized System
Drill core from BS-3 confirms a robust copper-molybdenum porphyry system with multiple stages of mineralization, indicative of a well-developed and long-lived hydrothermal system.
Link to the Diamond Joe System
Geochronological research supports a genetic link between Big Sandy and the Diamond Joe system, suggesting Big Sandy represents the offset upper portion.
Significant Exploration Upside
Mineral zoning and geological characteristics indicate Big Sandy may represent the outer shell of a porphyry Cu-Mo system, with the central high-grade copper-rich portion potentially still undiscovered.
Confirmed Critical Mineral Potential
Research has confirmed the presence and potential significance of multiple critical minerals including copper, molybdenum, rhenium, silver and other associated elements relevant to domestic supply chain priorities.
Rare Geological Profile
Big Sandy preserves an unusually complete profile from leached capping through supergene enrichment to primary mineralization, providing an important natural setting for research and exploration.
Ongoing Research and Continued Advancement
Ongoing research continues at the Big Sandy system, including doctoral-level studies at the University of Arizona focused on leached cap development and supergene enrichment processes.
