Satellites Hunt Minerals From Orbit

Satellites Hunt Minerals From Orbit
PhotographHyperspectral imaging and radar constellations are rewriting the economics of mineral exploration, cutting discovery timelines by 80% while oil and gas operators track subsidence with millimeter precision from space.

Hyperspectral satellites can now spot lithium deposits hidden beneath vegetation from 550 kilometers up. Mining companies using satellite-enabled mineral exploration are slashing traditional discovery timelines and costs by up to 80-85%, according to Farmonaut , which has deployed AI-driven analytics to screen vast areas for mineral potential in days rather than months. The shift from boots-on-the-ground surveys to orbital prospecting marks a fundamental change in how the energy and mining sectors find resources—and monitor the consequences of extracting them.

Pixxel's Firefly constellation, featuring six satellites designed for high-resolution hyperspectral imaging, launched successfully in 2025 and is now operating in orbit . Each satellite captures 135+ spectral bands at a 5-meter resolution across a 40-kilometer swath , enabling detection of changes invisible to conventional imaging systems. As of mid-2026, Pixxel's 5-meter ground sample distance at 135+ spectral bands represents the strongest offering in commercial hyperspectral imaging , according to industry analysis. The company counts Rio Tinto among its partners.

Can Satellites Replace Geologists?

Not entirely—but they're changing the job description. Unlike conventional multispectral sensors that capture a handful of broad bands, hyperspectral satellites record hundreds of narrow, contiguous spectral bands spanning from the visible to the shortwave infrared, allowing extraction of detailed chemical and physical information from land, crops, forests, and mining prospects .

Every mineral—lithium, copper, gold, rare earths—leaves its mark in the hyperspectral data, letting analysts spot deposits even when hidden under a thin layer of vegetation or soil , Farmonaut reports. Fleet Space Technologies has added gravity geophysical surveys to its ExoSphere mineral exploration solution, which has already attracted Rio Tinto, Barrick Gold, and other global mining companies using this subsurface imaging technology to discover buried deposits of cobalt, copper, lithium, nickel, and other critical metals .

The European Space Agency is backing the trend. Kuniko partnered with Poland-based EO analytics startup TerraEye to develop a remote sensing solution for prioritizing exploration targets using Copernicus Sentinel-2 imagery . Norway's harsh winters allow only a short seasonal window for on-site work, and each field campaign comes with high financial costs and potential risks , making satellite data particularly valuable for Arctic exploration.

What About the Ground Beneath Active Operations?

Interferometric Synthetic Aperture Radar—InSAR—has become essential for tracking ground deformation at oil fields and mine sites. InSAR is a satellite-based remote sensing technique that detects ground surface movement with millimeter-level accuracy across areas spanning hundreds of square kilometers by analyzing phase differences between radar images acquired at different times .

French mining group Eramet collaborated with Italian remote sensing specialist Tre Altamira to improve space-based subsidence monitoring at active and legacy sites, using Copernicus Sentinel-1 radar data and advanced InSAR techniques . Eramet is the largest producer of high-grade manganese ore worldwide, with global operations that provide essential critical metals needed for electrification and green energy .

For oil and gas operators, the stakes are equally high. Research at China's Fengcheng oil field revealed ground surface maximum cumulative uplift of 40 cm over four years, with annual average deformation rates ranging from -80 to 120 mm/year , demonstrating InSAR's capacity to track reservoir pressure changes from fluid injection. InSAR is used to track enhanced recovery, underground gas storage, and wastewater injection to support safety, environmental protection, and regulatory compliance in oil and gas operations .

SAR data are the most effective method for tracking land subsidence and structural damage, with land managers using SAR images to prepare subsidence risk assessments helpful for monitoring geohazards in mines and planning construction in cities , according to the European Space Agency. Sentinel-1D data became available to users through the Copernicus Data Space Ecosystem starting April 17, 2026, with the satellite positioned on an orbit that revisits the Sentinel-1C ground track with a one-day offset .

How Does LiDAR Fit the Picture?

Light Detection and Ranging technology complements satellite imaging for active mine operations. The mining industry is shifting away from fragmented, siloed information toward "connected workflows" by integrating data from robotic total stations, drones, and terrestrial 3D laser scanners, with mine surveyors now able to push field data directly to the office in real time , according to GIM International.

This approach utilizes cloud-based platforms to create a "common data environment," ensuring that geologists, engineers, and planners are all working from a single, unified digital twin of the mine site . Traditional surveying often required personnel to physically traverse dangerous high-risk zones, but modern LiDAR and remote sensing tools allow surveyors to capture high-density point clouds from a safe distance .

Nimbo's 2.5-meter high-resolution satellite data brings critical infrastructure and environmental controls into sharp focus, enabling clear identification of sediment ponds, buffer zones, and haul road networks that would otherwise be a blur in standard 10-meter imagery . The company provides monthly cloud-free imagery, critical for monitoring extraction and reclamation progress in cloud-prone tropical regions.

What Changed This Week

ESA awarded a €700 million contract to Thales Alenia Space for two Copernicus Sentinel-1 Next Generation satellites, expected to launch in the mid-2030s, with improved capabilities including a wider swath (400 km versus current 250 km) and higher resolution (5 x 5 m versus current 5 x 20 m) . The upgrade will benefit infrastructure monitoring, flood mapping, and maritime surveillance. Meanwhile, UK startup NewOrbit Space raised $18.5 million in a Series A round, with plans to launch first satellites in 2028 , targeting very low Earth orbit operations. Small satellite constellations are reshaping revisit frequency and coverage, with users now receiving multiple observations per day for the same location instead of waiting days or weeks for imagery , according to industry analysis.

What to Watch

Pixxel's Honeybee Zero satellite, planned for launch in 2026, will have expanded hyperspectral coverage from visible to shortwave infrared, equipped to provide hyperspectral imagery of approximately 450 bands total in the 400-2550 nm range at an 8-meter ground sample distance . The SWIR capability will unlock mineralogy and dry-matter analysis applications currently beyond the Firefly constellation's reach. Sentinel-1A operations will be terminated during June 2026, after which Sentinel-1C and Sentinel-1D will work in tandem and comprise the new Copernicus Sentinel-1 constellation , according to NASA Earthdata. Watch for how the transition affects InSAR monitoring continuity for energy and mining operators who have built workflows around the current constellation configuration.
