Explore how Fleet Space helped Fermi Exploration validate structural controls, reduce drilling risk, and make confident exploration decisions in one of the world's most challenging uranium provinces.
About Fermi Exploration and the Perch River project
Fermi Exploration Ltd is an early-stage uranium explorer focused on advancing a portfolio of high-potential assets encompassing 111,125.74 Ha in Saskatchewan, seven of which are located within the Athabasca Basin - home to the world's highest-grade uranium deposits.
At the Perch River Uranium Project, limited surface expression and deep cover created significant uncertainty around structure, target geometry, and drill prioritisation. To reduce this uncertainty and strengthen confidence ahead of drilling, Fermi partnered with Fleet Space to image subsurface structures, validate a fault-controlled hydrothermal system, and support more informed drill targeting decisions.
The Challenge
When early indicators exist, but uncertainty blocks action
Unconformity-related uranium systems are structurally controlled and deep, often with narrow geometries. At Perch River, Fermi had strong surface and near-surface indicators including anomalous uranium, radon, and isotopic signatures, but lacked confidence in the subsurface architecture.
The decision challenge was clear:
Was there a major structural conduit and any evidence of alteration related to potential uranium mineralisation?
Where should capital be allocated first to reduce exploration risk?
The Breakthrough
Closing the confidence gap
Fleet Space deployed its ExoSphere, using the platform's real-time Ambient Noise Tomography (ANT) to deliver high-resolution 3D subsurface imaging across complex and constrained terrain.
This revealed a deep, subvertical low-velocity zone extending to approximately 400 metres, interpreted by Fermi as a major fault-controlled corridor. The structure aligned with independent geochemical and isotopic anomalies and provided a defensible basis for drill targeting.
This was not an interpretation exercise. It was a decision-enabling outcome.
Fleet Space Delivered...
A drilling decision backed by evidence
Using insights delivered by Fleet Space's ExoSphere, Fermi designed a drill program to test the highest-confidence target.
The result validated the decision.
Drilling intersected a broad interval of uranium-related alteration, strong shearing and brecciation, and highly radiogenic lead isotope signatures consistent with Athabasca-style uranium systems.
Confirmed by drilling and geochemical data - the result validated the subsurface model.
From uncertainty to validated decision.

Why This Matters
Decision confidence builds when integration replaces silos
Fermi's outcome was enabled by integration, not a single method.
Fleet Space's approach combined real-time subsurface imaging with existing geological and geochemical data to produce a coherent, trusted decision framework. This allowed Fermi to move decisively in a complex geological setting where uncertainty is expensive.
This is Agile Geoscience in practice. Reduce uncertainty early. Act with confidence. Adapt fast.

Our mission began with a question: How do we explore other worlds?
To answer it, we had to reimagine how we understand our own.
Today, that vision powers ExoSphere™, a space-enabled sensing platform that helps humanity make smarter decisions across the most complex, remote, and valuable environments on Earth, and soon... beyond.
