Франция использует спутники и ИИ для поиска редких металлов под лесами Гвианы

France Turns to Satellites to Hunt Minerals Under French Guiana Mining Key Facts —The deal. France’s national geological survey, BRGM, signed a partnership with the Australian firm Fleet Space Technologies to map minerals under French Guiana. —The method. Fleet’s system links portable ground sensors to satellites and uses artificial intelligence to build fast three-dimensional pictures of the rock below. —The prize. The target is a belt of critical minerals such as lithium, copper, niobium and tantalum, hidden under dense rainforest. —The backdrop. It builds on France’s fifty-three-million-euro, five-year mineral inventory launched in 2025 to chart strategic resources at home and in the territory. —The stakes. Paris frames the effort as a matter of energy transition and industrial sovereignty, reducing reliance on outside suppliers. France is reaching for space technology to see what lies beneath one of the hardest places on Earth to explore. The hunt for French Guiana critical minerals is now a test case for a faster, lighter way to map the ground without tearing up the forest. The country’s national geological survey, known by its French initials BRGM, has signed a memorandum of understanding with Fleet Space Technologies. The Australian company maps the underground using a mix of satellites, ground sensors and artificial intelligence. French Guiana is an overseas territory of France on the northern shoulder of South America, wedged between Brazil and Suriname. Most of it is thick tropical rainforest, which makes traditional mineral surveys slow, costly and disruptive. Why French Guiana critical minerals matter now The push is about supply security. Europe wants dependable sources of the metals that batteries, magnets and defence systems rely on. It would rather find them on its own soil than depend on distant suppliers. According to BRGM’s own announcement, the work will first focus on new ways to gather and read geophysical data in the territory. It draws on Fleet’s platform and the survey’s long field experience there. The deputy head of BRGM called the ability to spot hidden deep deposits a critical issue. It matters both for the energy transition and for industrial sovereignty. The target is a mineral belt that runs across the north of the territory. It stretches from the capital Cayenne westward toward the border with Suriname. The belt is known to hold aluminium, copper, lithium, niobium and tantalum. These are the kind of metals now fought over in global supply chains. Space sensors instead of bulldozers The heart of the system is a portable, wireless sensor that needs no cabling to work. In jungle, laying the long cable grids of a normal survey often means clearing vegetation on a scale that would break environmental rules. Each sensor also does some computing on the spot, trimming the data before beaming it up by satellite. That cuts the wait between fieldwork and a usable underground map from months to something far quicker. Fleet was chosen through a formal contest BRGM ran in 2025 to find low-impact survey methods. So this is a considered pick rather than a one-off trial. The firm counts major miners such as Rio Tinto and Barrick among its clients. It says it has mapped hundreds of thousands of square kilometres across several continents. The firm’s approach leans on machine learning to read the sensor data and sketch the rock structures below. In practice, teams can adjust a survey while it is still running, rather than waiting for a distant lab to process results after the crews have gone home. French Guiana is best known abroad for its space centre at Kourou, from which Europe launches rockets. Its mineral wealth has drawn far less attention, partly because the forest has kept much of the ground out of sight. A blueprint beyond the territory Both sides stress the ambition reaches past this one jungle. BRGM says the aim is to build methods that can be reused in any remote or sensitive frontier, turning the project into a template for exploring difficult ground. For a foreign reader, the point is clear. A small, quiet corner of South America has become a proving ground for how rich nations intend to find the raw materials of the coming decades. The results could shape exploration far from the forests of French Guiana. There is a regional echo here too. Right next door, Guyana and Suriname have been transformed by offshore oil. The wider Guianas are increasingly seen as a resource frontier, whether the prize is crude beneath the sea or metals beneath the trees. Frequently Asked Questions What are French Guiana critical minerals? They are metals such as lithium, copper, niobium and tantalum thought to lie beneath the territory’s rainforest. They are prized because they feed batteries, magnets, electronics and defence gear, and supplies are increasingly contested worldwide. Does this mean mining is about to start? No, this is an exploration and mapping stage, not a mine. The partnership is about finding and understanding what lies underground, and any decision to dig would come much later and face strict environmental scrutiny.
