Coffer project
A Validated Uranium System with Room to Run
The Coffer Project gives Stallion exposure to a highly prospective part of the western Athabasca Basin, where regional structures, conductive trends, and alteration-style geophysical signatures create a strong foundation for continued uranium exploration.
42,075 Hectares
A sizeable land position in the southwestern Athabasca Basin, offering room for multiple target areas across one project.
100% Owned
Full project ownership gives Stallion flexibility to advance exploration, refine targets, and prioritize future drill programs
Multiple Target Zones
Appaloosa, Clydesdale, Holsteiner, and Mustang provide several distinct areas for follow-up exploration
Validated Drill Target
Initial drilling at Appaloosa intersected key structures, alteration and uranium-bearing indicators

Exploration targets
Four Targets With Momentum
The Coffer Project contains multiple target areas at different stages of advancement. Stallion’s work is focused on ranking these zones through geophysics, structural modeling, and follow-up drilling.
Appoloosa Target
The most advanced target at Coffer. Initial drilling intersected graphitic metasediments, alteration, and uranium-bearing structures, providing a foundation for follow-up targeting
Clydesdale Target
Defined by EM conductors and structural offsets. Future work is expected to refine the highest-priority drill locations.
Holsteiner Target
Located along an interpreted uranium corridor with conductor systems, crosscutting structures, and subtle resistivity features.
Mustang Target
Marked by basement conductors and structural intersections that may create favorable traps for uranium mineralization.
APPALOOSA TARGET
First-pass drilling confirms a prospective uranium system
Appaloosa was advanced from regional geophysics into ground-based surveying and diamond drilling. The maiden program confirmed key geological features, including graphitic basement rocks, alteration, and uranium-bearing structures, supporting continued target refinement.
2,798.2 metres
Completed across three diamond drill holes during the maiden drill program.
1,540 CPS
CF24-001 returned a 4.2 m radioactive interval averaging 358 cps, including 0.3 m at 1,322 cps.
ANOMALOUS U
CF24-003 averaged 5 ppm U across the graphitic structure, with assays up to 14 ppm U.
Follow-Up Potential
Results provide vectors for future drilling along strike and up dip.

EXPLORATION ROADMAP
From Data to Drills
Coffer’s next phase is focused on refining target geometry, ranking priority zones, and advancing the strongest conductors toward additional drill testing.
Model the System
Integrate airborne EM, ground TDEM, magnetic, gravity, and drill data into a unified targeting model.
Rank the Targets
Prioritize Appaloosa, Clydesdale, Holsteiner, and Mustang based on structure, alteration, and conductor strength.
Refine Drill Locations
Use geophysical modeling and downhole data to sharpen target vectors before additional drilling.
Test Priority Zones
Advance the strongest targets through focused drill programs designed to evaluate uranium-bearing structures.
