The announcement came without fanfare last November. Fleet Space Technologies, an Adelaide-based company most people had never heard of, revealed that its satellite-powered AI system had helped expand a lithium deposit in Quebec's James Bay region—significantly. But here's what made industry insiders take notice: this wasn't a press release promising future breakthroughs. This was actual drill results.
One hole at Q2 Metals' Cisco Lithium Project returned 272.5 meters grading 1.61% lithium oxide. The exploration target, still conceptual and awaiting formal resource definition, now stretches between 215 and 329 million tonnes. In an industry where new lithium deposits remain maddeningly elusive despite soaring demand, these numbers carry weight.
More striking than the discovery itself, perhaps, is what it represents: a decade-long bet on using space infrastructure to find critical minerals, a bet that could have easily collapsed into irrelevance but instead appears to be paying off at scale.
Fleet didn't stumble into this moment. The company has been building toward it since 2015—through satellite launches that barely registered in the news cycle, funding rounds that required patient explanations of why space technology belonged underground, and a pivot that could have broken the business rather than remaking it.
The Technology Stack Nobody Asked For
Fleet's approach marries three distinct elements: a constellation of nanosatellites in low Earth orbit, ground-based sensors called Geodes, and AI processing that turns raw data into drill targets within 48 hours. That last part matters. Traditional exploration campaigns can take months to yield actionable intelligence.
The Geodes employ passive seismic methods—specifically ambient noise tomography—to image subsurface geology down several kilometres. They're considerably more sensitive than standard exploration nodes, with over 30 decibels lower self-noise below 5 Hz, according to peer-reviewed testing published in academic journals. That sensitivity translates directly into shorter recording times and faster answers, which in turn means lower costs.
The satellites handle data backhaul from sites where cell towers don't exist and won't exist anytime soon. Last October, Fleet added gravity surveys to the platform, creating what CEO Flavia Tata Nardini terms "multiphysics imaging." The AI layer—branded ExoSphere Discovery—ranks targets by synthesizing geophysical data, drilling results, and client-specific inputs into a coherent exploration strategy.
At Cisco, this technology allowed Q2 Metals to extend their mineralized envelope beyond the initial footprint and refine drilling targets iteratively. The project earned finalist status for the Association of Exploration Geochemistry of Quebec's Discovery of the Year award in 2025, a distinction that carries credibility in a skeptical industry.
From IoT Satellites to Mining's Frontier
The origin story begins elsewhere entirely.
Flavia Tata Nardini, an Italian aerospace engineer who had worked on propulsion systems at the European Space Agency and TNO in the Netherlands, moved to Adelaide and co-founded Fleet with Matt Pearson in 2015. Their initial thesis centered on satellite-enabled Internet of Things connectivity using LoRa and low-power wide-area networks. Early customers included Kennards Hire, an equipment rental company tracking assets across construction sites.
Between 2018 and 2022, Fleet launched six Centauri satellites via ISRO, SpaceX, and Rocket Lab missions. The business model—connectivity as a service—showed promise but never quite achieved escape velocity. The pivot emerged when someone on the team realized their satellite backhaul could solve a fundamentally different problem: extracting seismic data from locations so remote they made "off the grid" sound optimistic. Mining exploration happens precisely in those places.
By 2021, when Fleet closed a $26.4 million Series B led by Blackbird and Grok Ventures (among others), the company had repositioned itself as an exploration technology provider. The Series C in May 2023 brought $50 million and pushed valuation above $350 million. That round explicitly targeted global expansion of the ExoSphere platform. Fleet opened offices in Houston, Ottawa, Santiago, and Luxembourg—cities chosen not for glamour but for proximity to mining capital and talent.
The Series D, closed in December 2024, raised $100 million at roughly an $800 million valuation. Teachers' Venture Growth, the venture arm of Ontario Teachers' Pension Plan, led. By then Fleet employed north of 130 people and counted Rio Tinto, Barrick Gold, and Ma'aden among its clients. Not bad for a company that started by tracking rental excavators via cubesats.
Enterprise Scale, Not Pilot Projects
The Ma'aden deal illustrates how far Fleet has traveled from those early IoT ambitions.
Signed in May 2025, the agreement commits Saudi Arabia's state mining company to deploy Fleet's technology across 12,012 square kilometres of the Arabian Shield over four years, working through a joint venture with local partner Tahreez. That's not a pilot program. That's industrial-scale deployment with geopolitical implications—Saudi Arabia has made no secret of its ambitions to develop domestic mining capacity as a hedge against oil dependency.
Similarly, Barrick is using ExoSphere to map 1,150 square kilometres at Reko Diq in Pakistan, home to one of the world's largest undeveloped copper-gold deposits. Inflection Resources deployed the platform over 1,818 square kilometres in Australia's Macquarie Arc, billing it as the largest real-time ambient noise tomography copper survey on record. (Whether that's marketing or genuine industry leadership depends on who you ask, but nobody's disputed the claim publicly.) Gold Fields took Fleet's sensors to between 3,900 and 4,700 meters elevation in Chile, setting an altitude record for the method and proving the technology functions in conditions that would incapacitate most electronic systems.
In March 2025, Fleet made its first acquisition—buying HiSeis to add active seismic capabilities to a platform built around passive methods. The move broadened Fleet's technical repertoire but also raised questions about integration complexity. Then in October, the company opened new global headquarters at Adelaide Airport: a 5,300-square-meter facility it calls a "hyperfactory," designed to manufacture thousands of sensors and hundreds of satellites annually. Whether that capacity proves prescient or overbuilt depends entirely on demand materializing at the scale Fleet anticipates.
Nardini told the Australian Financial Review mid-2025 that Fleet could become "one of the biggest tech companies in the world." It's the sort of statement that invites eye-rolling from those who've heard Silicon Valley-style hyperbole before. Except Fleet keeps signing contracts that suggest major mining companies believe at least part of the pitch. Rio Tinto doesn't deploy unproven technology across critical exploration programs as a favor.
Beyond Earth's Crust
Fleet's ambitions extend past terrestrial minerals, naturally.
The company's SPIDER payload is manifested on Firefly Aerospace's Blue Ghost Mission 2, scheduled to touch down on the Moon's far side as early as 2026. SPIDER is essentially a seismic package designed to test whether the ambient noise methods that work in Quebec's boreal forests can work 384,400 kilometres away in lunar regolith. If they do, Fleet gains validation that its technology travels. If they fail, it becomes an expensive but instructive science experiment—and a cautionary tale about overreach.
The defence angle has grown more prominent, too. Last November, Fleet demonstrated two-way voice and data transmission over its Centauri-6 microsatellite for the Australian Defence Force under the ASCEND2LEO program. In March 2025, it delivered a full sovereign satellite communications plan to the ADF. Whether that represents a strategic hedge against mining market volatility or a genuine second act depends on how seriously one takes the military communications market. Either way, it diversifies revenue streams beyond critical minerals exploration.
Proof, Not Promise
The lithium discovery at Cisco matters because it transforms Fleet's narrative from theoretical to empirical. The company can now point to drill intercepts, to an exploration target that Q2 Metals will spend the next 18 to 24 months converting into a bankable resource, and to industry recognition from geologists who know James Bay's geology intimately. That's considerably harder to dismiss than a well-designed pitch deck animated with satellite renderings.
Whether Fleet evolves into the global technology giant Nardini envisions—or remains a well-funded but ultimately niche player in exploration tech—hinges on replicating the Cisco success story. Repeatedly. At scale. Across commodities and continents. Right now, the company possesses momentum, capital, and a technology platform that major miners are deploying beyond pilot-program stages. For a business that launched by connecting rental equipment via cubesats barely larger than shoeboxes, that represents a remarkable trajectory.
The more interesting question, perhaps, is whether the next decade compounds that progress or reveals its limits. Fleet has built the infrastructure. The deposits, stubborn as ever, will ultimately decide whether the bet was visionary or merely expensive.
