DeepBEAT - Innovative Geochemical Approaches for Sustainable Exploration of Deep-Seated Mineral Resources

The growing demand for critical raw materials, such as rare earth elements, cobalt, and lithium, is driven by their indispensable role in renewable energy technologies, battery systems, and advanced electronics. As near-surface deposits of these materials are increasingly depleted, the focus of mineral exploration is shifting to concealed and deep-seated deposits, which present significant challenges in both detection and extraction. This study presents a comprehensive, interdisciplinary approach to advancing surface-based geochemical exploration techniques, enabling more precise targeting of hidden mineral resources while minimising environmental impact and maximising sustainability.

Central to this research is the integration of advanced exploration technologies with innovative geochemical methods. The project emphasises the development of refined surface geochemical techniques to identify subtle anomalies in elemental composition that signal the presence of deep ore systems. By combining geochemical data with geophysical evidence, the study aims to provide a holistic understanding of ore-forming processes and their surface expression. Recent advances include the application of ultra-high-resolution analytical chemistry, cost-effective and efficient sampling strategies, and the exploration of new phyto-geochemical media. Furthermore, UAV-assisted biogeochemical sampling introduces an innovative dimension, enhancing the accessibility and precision of data collection in challenging terrains.

A key feature of the project is the incorporation of artificial intelligence (AI)-assisted 3D mineral prospectivity modeling, which enables the integration of diverse datasets to produce highly accurate predictive models. This technological synergy not only improves the resolution of mineral targeting but also significantly reduces exploration costs and environmental impacts by optimizing sampling strategies and minimizing invasive practices.

The DeepBEAT project also addresses the broader societal and environmental dimensions of mineral exploration. By focusing on sustainable methodologies, the research prioritizes minimizing ecological disruption while fostering transparency and acceptance among stakeholders. The outcomes of this study contribute to advancing global capabilities for securing critical raw materials, which are essential for achieving a sustainable, technology-driven future.

Overall, this work pushes the boundaries of surface geochemical exploration by uniting state-of-the-art analytical, geophysical, and data-processing technologies. The results provide a transformative framework for the precise and sustainable detection of deep-seated mineral systems, laying the foundation for a responsible and resilient raw materials supply chain.
