How do we explore what’s hidden beneath our feet? The mining industry has long relied on techniques like seismic surveys, ground-penetrating radar, and electrical resistivity to map underground structures. Now, muography is emerging as a low-impact, high-precision imaging tool that enhances mineral exploration, helping to identify deposits and optimize extraction with minimal disruption.
Traditional vs. Emerging Mining Exploration Techniques
In our previous Substack post, we introduced muography and how Ab Astra is advancing this revolutionary imaging technology. If you haven’t read it yet, check it out here. Today, we’re diving deeper into one of its most promising applications: mining exploration.
Before we explore muography’s role, let’s look at some of the most widely used exploration techniques:
Seismic Reflection and Refraction: Detects rock formations by analyzing how seismic waves travel through different materials.
Ground-Penetrating Radar (GPR): Uses electromagnetic waves to detect shallow subsurface structures.
Electrical Resistivity Tomography (ERT): Measures how electrical currents move through underground materials, identifying variations in rock composition.
Gravimetry and Magnetometry: Detects slight changes in gravitational and magnetic fields to infer the presence of mineral deposits.
While these methods are effective, as any others they have limitations: resolution issues, high costs, and the need for extensive drilling. This is where muography brings a new dimension to exploration.
Muography: Seeing Beyond Traditional Limits
Muography leverages naturally occurring muons—subatomic particles generated in the atmosphere by cosmic rays—to create detailed images of dense underground structures. Unlike seismic or electromagnetic methods, muons penetrate even the densest materials, making it possible to map cavities, faults, and ore deposits with precision.
Works in extreme environments: Operates in deep underground mines where other techniques struggle.
Provides continuous data: Muon detectors can remain in place for long-term geological monitoring.
Complements existing techniques: Results can be combined with other methods to improve resolution and accuracy.
According to recent studies, muography is showing great potential in mining operations. Recent research published in the prestigious Nature Scientific Reports highlights how muon imaging is being integrated into mineral exploration as a cost-effective and environmentally friendly alternative (Nature - Scientific Reports, 2022).
Who Is Using Muography in Mining?
Several research institutions and mining companies are starting applying muography to real-world mining operations:
China – The University of Lanzhou has successfully tested muon imaging for geological mapping in a gold mine, demonstrating its effectiveness in identifying underground structures (Geophysical Journal International, 2024).
Italy – Researchers at the University of Florence are studying how to use muography to identify ores in skarn complexes at the Temperino Mine in Campiglia Marittima (Natural Resources Research, 2023).
Europe & the US – Several institutions and mining companies are integrating muon detectors into active mining sites to improve subsurface mapping (ASEG, 2019).
Ab Astra: Advancing Muography for a More Sustainable Future for Mining
At Ab Astra, developed by piensas.xyz and Quant Energy, we are pushing the boundaries of muon-based imaging by developing:
Next-generation muon detectors with higher sensitivity for deep mineral exploration.
AI-driven data analysis to process and interpret large muon datasets more efficiently.
Portable, scalable solutions that can be deployed across various mining environments.
These advancements will allow mining companies to improve resource estimation, optimize drilling strategies, and enhance mine safety.
Muography is not just another exploration tool—it represents a fundamental shift in how we explore and extract resources. By offering a clearer, non-invasive, and environmentally friendly way to study the subsurface, it has the potential to revolutionize mineral exploration.
