On 25 April 2025, the S34I project hosted a dynamic and insightful webinar titled “S34I Project Insights: Cutting-Edge Techniques & Results for Sustainable Raw Material Supply.” Bringing together researchers, geologists, and innovators in raw materials, the session highlighted breakthrough approaches developed within the S34I framework, aimed at enhancing the sustainable exploration and supply of critical raw materials across the EU.

The event was opened by Ana Teodoro from the University of Porto, who welcomed participants and set the stage for an engaging session on scientific progress and practical applications.

Pioneering Spectral Methods for Ore Deposit Exploration

The first presentation was delivered by Mercedes Suárez from the University of Salamanca, who unveiled findings from a case study at the Aramo Plateau in Asturias, Spain. Her presentation, titled “VNIR-SWIR spectroscopy for the prospecting, exploration, and exploitation of ore deposits,” focused on the use of spectral analysis in detecting and validating signatures of valuable minerals such as copper (Cu), cobalt (Co), and nickel (Ni).

Suárez detailed how these spectral techniques—central to the goals of the S34I project—can be used to optimise mineral exploration while reducing environmental impact. She also shared additional case examples showcasing the application of mining spectral signatures.

Innovative TEM Approach Piloted in Vigo, Spain

The second session, led by Francisco Javier González Sanz (IGME) and Antonio Ruiz (GeoExplorer.es), introduced a novel methodology known as TEM (electro-magnetic sieving) through the presentation “A New Approach to Mineral Prospecting & Case Study in Vigo, Spain.”

The speakers outlined the principles behind this technique and its application in the prospecting of heavy mineral layers in coastal placer deposits. Emphasis was placed on geophysical validation, field results, and the broader implications for sustainable mineral exploration across Europe.

A Platform for Exchange and Future Collaboration

The webinar concluded with a lively Q&A session and closing remarks, underscoring the importance of scientific cooperation and innovation in addressing Europe’s raw material challenges. Organised by the Iberian Sustainable Mining Cluster (ISMC) in collaboration with key academic and research institutions, the event reflected the S34I project’s commitment to delivering practical, science-based solutions from sky to soil.
