European researchers are using satellite imagery, drone data, and ground surveys to develop digital solutions for future mineral extraction.
Above Spain, Sweden, and Albania, researchers are mapping minerals from space. Three different locations, but the purpose is the same: to make mineral exploration and mining sustainable and cost-effective.
The European project MINEYE has spent the past two years combining data from satellites, drones, and ground-based measurements to understand mineral deposits better, both where they are found and what happens when they are extracted. The project partners recently gathered in Crete to summarise the work so far and plan the next phase.
“We have made significant progress. We have collected field data from all three areas, analysed the results, and laid the groundwork for the next phase, where we will verify the technologies”, says Sean Salazar, who coordinates the project from the Norwegian Geotechnical Institute (NGI) in Oslo.
Satellites supporting the mining industry
Modern mining is not just about digging. It is about understanding the geology, the ore resources, and, not least, the environmental impacts before, during, and after extraction. This is where geophysical mapping and space-based technology prove highly valuable.
MINEYE uses Europe’s Copernicus observation system, along with commercial satellites and specialised sensors, to detect both known and hidden minerals. What makes this particularly interesting is that all the data is now being ‘fused’ in the same analysis to create accurate 3D models of what lies beneath the surface.
“By integrating different types of new datasets into advanced models, we get a far more comprehensive picture than before”, Salazar explains.
From Swedish forests to Portuguese mining waste
The EU project is testing its methods at widely different locations to ensure the technology works universally.
In Sweden, researchers are combining satellite data with airborne geophysical measurements to map large mineralisation zones in the north. In Albania, they are mapping what can be extracted around an active mine. In Spain, they are studying new mineral deposits and the environmental impacts of abandoned mines. In Portugal, they are examining old mine tailings to see whether modern technology can extract valuable, critical raw materials from what was previously considered mere waste.
“Europe has not fully exploited its potential to explore and extract the critical minerals needed for the green and digital transition. MINEYE aims to make European mining more competitive and sustainable”, Salazar explains.

Industry awaiting results
The project is a collaboration among 13 partners from 9 European countries: universities, research institutes, technology providers, and mining companies.
“This technology can help reduce the environmental footprint and provide the objective data necessary to increase public acceptance of new mining projects”, says Salazar.
The project is due to be completed in 2028. By then, the researchers hope to have digital tools that mining companies across Europe can adopt for efficient mineral extraction.
