The Australian space startup Fleet Space has revealed that its satellite-powered AI system has significantly expanded the estimated size of an existing lithium deposit in Quebec — potentially boosting the deposit well beyond prior estimates and giving the region “district-scale” status. The company used its orbital sensors, which employ a mix of electromagnetic and gravity sensing, to map subsurface features and identify new mineral signatures in as little as 48 hours — a dramatic acceleration compared with traditional drilling-based surveys. This breakthrough marks one of the first times space-based mineral exploration has demonstrated real commercial promise.

Key Takeaways
– Fleet Space’s satellite-AI method could significantly lower the cost, time and uncertainty of mineral exploration, replacing years of exploratory drilling with rapid, orbit-based surveying.
– The expanded lithium deposit in Quebec — previously estimated at 329 million metric tonnes of lithium oxide — may now be far larger, highlighting potential for new “district-scale” mining regions in North America.
– If broadly adopted, this technology could shift the balance of critical-mineral supply toward more domestic sources, benefiting battery makers and reducing dependence on geopolitically risky mining regions.
In-Depth
For decades, mineral exploration has looked the same: crews of geologists and drilling rigs, expensive field operations, and drawn-out periods of uncertainty as companies hope core samples confirm paydirt. Success rates have historically been abysmal — only a tiny fraction of prospects ultimately turn viable. Enter a paradigm shift: the space-based, AI-driven mineral exploration model of Fleet Space.
By placing a constellation of small satellites into orbit and equipping them with electromagnetic and gravimetric sensors, Fleet Space can effectively “scan” vast swaths of Earth’s crust from above. Then, its proprietary AI software interprets the data, mapping subsurface geologic features and identifying mineral signatures that ground-based teams might miss — all from thousands of miles overhead. For the Quebec project, known until now as the Cisco deposit, this approach revealed that the deposit extends far beyond its previously understood boundaries, giving new credence to the idea of “district-scale” lithium reserves.
That matters a great deal in the current global economic context. With electric vehicles, battery storage for renewables, and broader electrification ramping up worldwide, demand for lithium is exploding. Yet supply remains constrained — in many cases located in politically unstable or environmentally challenged regions. A robust, North American lithium source changes that calculus. If Fleet Space’s results hold up through drilling and verification, Quebec could become a strategic domestic supply hub for batteries, reducing reliance on overseas mining and bottlenecks that have plagued supply chains.
Moreover, the cost and risk reductions are potentially game-changing. Conventional mineral exploration is slow, capital-intensive, and risky — so much so that the majority of prospects never pan out. Fleet Space’s satellite-AI method, which compresses what once took years into days, could dramatically improve success rates while lowering environmental disruption; satellite detection can guide drilling to exact spots rather than requiring broad swaths of exploratory drilling.
In short: if this model scales, minerals critical for the clean-energy transition — lithium, nickel, cobalt, rare earths — could become easier to locate, cheaper to extract, and more sustainably sourced. That’s not just a win for mining companies or battery-makers; it’s a strategic shift that could reshape supply-chain dynamics, energy-security posture, and even national policy around mineral resources.
Of course, there remain important caveats: satellite-detected “signatures” must still be confirmed by drilling; regulatory and environmental approvals will still apply; and building out full-scale mining operations will take time. But the fact that a driller’s tool has gone orbital — and already delivered tangible results — suggests that the future of mining may not be dirt under boots, but data from space.
