Critical Minerals Site Tracking

Persistent satellite monitoring of critical mineral extraction sites globally, combining multispectral, SAR and hyperspectral imagery to track production, expansion and disruption in near-real time.

Governments that depend on imported critical minerals — lithium, cobalt, nickel, rare earths, graphite — are flying blind. They know roughly which countries host the deposits, but they have almost no independent visibility into actual production rates, site expansions, tailings pond growth, or the early signs of a supply disruption. Commercial mine operators and foreign governments control that information, and they share it selectively. A sovereign satellite programme changes that equation by giving national ministries, strategic stockpile managers and industrial policy teams a continuously updated, independently verified picture of every site that matters to them.

The satellite stack combines multispectral imagery (10 m resolution, weekly cadence) for vegetation disturbance and haul-road activity, synthetic aperture radar for all-weather site-change detection, and targeted hyperspectral passes to infer mineralogy and ore-grade proxies from spectral signatures. Machine-learning change-detection models flag new excavation fronts, tailings expansion beyond licensed boundaries, stockpile volume changes and infrastructure construction. The result is a ground-truth layer that no corporate sustainability report or trade statistic can replicate.

The operational payoff is direct. A ministry of energy or mines can spot a production curtailment at a foreign cobalt operation three to six weeks before it shows up in shipping data or spot-market prices — enough time to accelerate domestic stockpile drawdown, redirect procurement or trigger diplomatic engagement. The same data feeds environmental compliance teams tracking whether extraction licences granted to foreign-invested entities are being respected. Sovereign ownership of the pipeline means the intelligence is not sanitised, delayed or withheld by a commercial vendor whose other clients include the very mining conglomerates being watched.

What matters

A single major mine supplying 60 %+ of a critical mineral can swing global prices by 20-40 % within weeks of a production halt — early warning is measured in days, not months.
Hyperspectral mineral mapping at 10-30 m resolution can detect iron-oxide alteration halos and clay-mineral assemblages that indicate ore-grade zones invisible to standard RGB or multispectral sensors.
SAR coherence change detection identifies ground subsidence and new excavation fronts through cloud cover, which is operationally decisive in tropical mining regions with 200+ overcast days per year.
Commercial satellite vendors routinely license the same mine-monitoring analytics to the mining companies themselves, creating an inherent conflict of interest that sovereign-operated data pipelines eliminate.

Sovereignty score: 9/10 — A nation that cannot independently monitor foreign critical mineral sites is entirely dependent on the goodwill of producers, commercial data brokers and allied intelligence partners for the supply intelligence that underpins its industrial base and defence manufacturing.

Export-control and licensing restrictions mean leading commercial SAR and hyperspectral analytics vendors (US, EU) can withhold or degrade access precisely when geopolitical tensions — the moment supply data is most valuable — make it inconvenient to share.
Mining conglomerates routinely hold equity in satellite analytics platforms; a nation subscribing to a commercial mine-monitoring service may be feeding its procurement intelligence to the very counterparty it is trying to assess.
Critical minerals underpin battery technology, defence electronics and rare-earth permanent magnets; supply-chain intelligence at this level falls within the remit of national economic security doctrine in the EU (Critical Raw Materials Act), US (DPA Title III) and equivalent frameworks, requiring data to remain under sovereign classification control.
Domestic hyperspectral and SAR processing infrastructure, once built for this application, doubles as the foundation for agricultural yield monitoring, environmental enforcement and geological survey — compounding the return on sovereign investment.

Reference architecture

Payload: Primary: pushbroom hyperspectral imager, 400-2500 nm, 10 nm spectral resolution, 20 m GSD, 30 km swath — for mineralogy and ore-proxy mapping. Secondary: multispectral imager, 8-band 400-900 nm, 5 m GSD, 60 km swath — for change detection and haul-road activity. Tertiary: X-band SAR, 3 m stripmap / 1 m spotlight, 30 km swath — for all-weather site change and subsidence.
Bus class: ESPA-class microsat, 150-200 kg, 700 W payload power — required to support hyperspectral cooling and SAR peak power; cubesat form factor insufficient for hyperspectral aperture at this GSD.
Orbit: Sun-synchronous LEO at 500-550 km; 6-satellite constellation (2 hyperspectral, 2 multispectral, 2 SAR) in three complementary orbital planes; 3-5 day full-revisit per site globally, daily tasking for priority sites.
Ground segment: 3-station sovereign network (X-band downlink, S-band TT&C) at geographically separated sites; direct-to-ground at 800 Mbps X-band per pass; SatNOGS UHF/VHF backup for housekeeping telemetry; on-premise mission planning system with 24-hour tasking uplift cycle.
