ExoSphere Unlocks Geological Potential of America’s Largest Copper Producing Region

Fleet Space Technologies, Australia’s leading space exploration company, deployed its end-to-end mineral exploration solution, ExoSphere, to enhance Eagle Mountain’s data-driven copper exploration at their Silver Mountain Project in Arizona. Leveraging ExoSphere’s real-time 3D subsurface mapping capabilities, powered by space technology and AI, Eagle Mountain uncovered new insights that underscore the potential for large mineralised systems and identified multiple unknown targets at Silver Mountain. 

“We’re proud to deploy ExoSphere to accelerate the geological understanding of the United States’ premiere copper producing region and drive more sustainable outcomes across the exploration value chain,” said Flavia Tata Nardini, Co-Founder & CEO of Fleet Space. “Space, 3D multiphysics, and AI are vital technologies that can make US efforts to strengthen its domestic critical mineral supply chain faster and more scalable, while minimising environmental footprint. We’re thrilled to bring the latest advances in these technologies and Fleet Space’s deep expertise from the forefront of copper exploration globally to deliver unparalleled geological insights that further America’s ambitions in AI, electrification, and clean energy technologies.”

Laramide: Exploring America’s Leading Copper Province

Accounting for 74% of US copper production, Arizona is central to America’s manufacturing and national security priorities, providing tens of thousands of jobs and $4.87 billion impact for the Arizona economy as one of the leading sectors in the state. In the list of top copper-producing countries globally — led by Chile and Peru — Arizona, as a US state, would be the 7th largest copper producer in the world. Eagle Mountain is a leading copper explorer committed to building their Oracle Ridge Copper Mine and Silver Mountain Project into low-emission sources of high-grade copper production to supply the skyrocketing demand for green energy. Located in the second largest copper porphyry province on Earth, their Silver Mountain project sits on the Laramide Arc, a geological feature connected to the eastern half of the Pacific Ring of Fire that includes several of the world’s largest copper discoveries such as Bagdad, Miami, and Resolution. 

ExoSphere: New Findings Accelerate Silver Mountain Exploration

Due to complications resulting from complex sediment cover, several geophysical techniques were unable to reliably pinpoint deeper targets at the Silver Mountain Project. This led Eagle Mountain to deploy Fleet Space’s ExoSphere solution, to generate high-resolution 3D imaging of their target zones up to 2.5km in depth. The subsurface insights delivered by ExoSphere revealed new indicators of large-scale mineralised systems - identifying deep porphyry-style targets and surrounding alteration zones, vital features for defining potential mineralising fluid and heat sources deep undercover. 

The survey also enhanced Eagle Mountain’s understanding of regional structures, such as the Breakaway Fault system running NNW-SSE in the Scarlett area, delivering new findings about structures thought to be controlling mineralization in the region. Velocity zones consistent with porphyry-style intrusions were also found, identifying previously unknown large-scale targets in the project’s unexplored western target zone. As a result of the new findings, Eagle Mountain shifted Silver Mountain to a top priority - accelerating their exploration activities at the site.

“The real-time 3D imaging capabilities of Fleet Space’s end-to-end solution, ExoSphere, helped us rapidly enhance our geological understanding of the Silver Mountain project, reduce uncertainty, and deliver multiple high-priority targets for further exploration,” said Tim Mason, CEO of Eagle Mountain. “The insights we gained from the ExoSphere survey have unlocked the geological potential of our Silver Mountain project, solidifying its place in our exploration strategy moving forward.”

Next-Level Insight: Copper Exploration Powered by Space and AI

Fleet Space’s first deployment of ExoSphere in America’s leading copper producing region in Arizona builds on the soaring global adoption of the end-to-end solution among leading copper producers and exploration companies. Barrick Gold recently used ExoSphere to generate 3D subsurface maps of copper porphyry complexes for multiple zones of interest across 1,150 Km² of their Reko Diq project in Pakistan. Fleet Space also conducted the world’s largest real-time Ambient Noise Tomography survey across Australia’s premiere copper-porphyry province — the Macquarie Arc — encompassing over 1818 Km² of Inflection Resource’s projects in the region.

Powered by Fleet Space’s proprietary satellite constellation, smart seismic sensors, and AI, ExoSphere radically streamlines data acquisition, processing, integration, and insight delivery into a single end-to-end solution. Used to complete hundreds of surveys across five continents for many of the world’s largest explorers — like Barrick Gold, Rio Tinto, and Core Lithium — ExoSphere enhances the quality, speed, and effectiveness of decision making with AI-powered, 3D subsurface insights at every stage of exploration while driving more sustainable outcomes at scale. Rapid global adoption of ExoSphere has fueled Fleet Space’s exponential growth over the past year, including a A$50 million Series C funding round, doubling the company’s valuation to A$350 million; the deployment of a lunar variant of ExoSphere on the Moon in 2026; and recognition as Australia’s fastest growing company.
