The article focuses on the mining industry's adoption of muon tomography, a subatomic-particle sensing technology, to improve subsurface imaging for deeper and more efficient extraction of critical minerals. Muons, produced by cosmic rays, penetrate deep underground and enable high-resolution, three-dimensional mapping of rock density, which is crucial for managing risks and productivity in block caving—a cost-effective underground mining method used for lower-grade ore deposits. Canadian start-up Ideon Technologies has miniaturized muon detectors for field use and integrates their data with other geophysical measurements in a dynamic Earth model called Reveal, enhancing real-time monitoring of underground conditions. This technology aims to reduce uncertainties in ore extraction, improve safety by detecting voids and faults, and support the expansion of existing mines, such as Rio Tinto’s Kennecott Mine, amid rising global demand for critical minerals.
