Special Issue Information

Dear Colleagues,

The global demand for critical minerals, driven by technological advances and the shift to renewable energy, necessitates innovative exploration techniques. Traditional methods often fall short in addressing the complexities of locating these essential resources. Smart mineral exploration, utilizing cutting-edge technologies, offers a solution by integrating multi-source data to enhance mineral prospectivity mapping.

This Special Issue explores the transformative potential of smart mineral exploration for critical minerals. In recent years, advances in artificial intelligence (AI) and machine learning (ML) have revolutionized mineral exploration by enabling the integration of diverse datasets from geophysical, geochemical, remote sensing, and geological sources. These innovations have not only enhanced the accuracy and efficiency of mineral prospectivity mapping (MPM), but have also opened new avenues for discovering previously overlooked mineral deposits. This Special Issue explores the transformative impact of these technologies on MPM, emphasizing both knowledge-driven and data-driven approaches.

We welcome specific contributions related to the following:

  • Smart mineral exploration, highlighting innovative tools and techniques that enhance the exploration process.
  • AI- and ML-aided mineral exploration, showcasing case studies and applications that leverage these technologies for improved predictive capabilities.
  • Advanced 2D and 3D knowledge-driven and data-driven MPM, focusing on integrating traditional geological knowledge with modern data analytics.
  • Numerical simulation and big data analytics for mineral exploration, presenting methodologies that handle large datasets to uncover hidden patterns and insights.
  • Geochemical and geophysical anomaly mapping, detailing methods that identify and analyze anomalies indicative of mineral deposits.
  • Remote sensing- and GIS-based MPM, discussing the use of remote sensing data and GIS technologies to map and predict mineral occurrences.

This issue provides an overview of smart mineral exploration, highlighting the synergy between various data sources and technologies. By showcasing the latest research and applications, we aim to inspire innovation and collaboration, contributing to the sustainable exploration of critical minerals.

Mineral prospectivity mapping (MPM) is crucial for efficient mineral exploration, where prospective zones are identified in a cost-effective manner. This study focuses on generating prospectivity maps for hydrothermal polymetallic mineralization in the Feizabad area, in northeastern Iran, using unsupervised anomaly detection methods, i.e., isolation forest (IForest) and deep isolation forest (DIF) algorithms. As mineralization events are rare and complex, traditional approaches continue to encounter difficulties, despite advances in MPM. In this respect, unsupervised anomaly detection algorithms, which do not rely on ground truth samples, offer a suitable solution. Here, we compile geospatial datasets on the Feizabad area, which is known for its polymetallic mineralization showings. Fourteen evidence layers were created, based on the geology and mineralization characteristics of the area. Both the IForest and DIF algorithms were employed to identify areas with high mineralization potential. The DIF, which uses neural networks to handle non-linear relationships in high-dimensional data, outperformed the traditional decision tree-based IForest algorithm. The results, evaluated through a success rate curve, demonstrated that the DIF provided more accurate prospectivity maps, effectively capturing complex, non-linear relationships. This highlights the DIF algorithm’s suitability for MPM, offering significant advantages over the IForest algorithm. The present study concludes that the DIF algorithm, and similar unsupervised anomaly detection algorithms, are highly effective for MPM, making them valuable tools for both brownfield and greenfield exploration.
