LISBON VALLEY URANIUM ACQUISITION
Overview
- 217 contiguous claims dominating the east flank of Lisbon Valley.
- Agreement with Big Indian Prospectors LLC to acquire uranium claims in San Juan County, Utah.
- Existing road & mining infrastructure accelerated exploration timelines.
- Under-tested structural block with proven regional endowment.
- ~ 78 Mlbs U₃O₈ historial production • Average grade ~0.37% U₃O₈.
- Classic salt-anticline-hosted uranium system.
Geology
-
Historic mining concentrated on west flank of Lisbon Valley anticline.
-
East flank down-dropped ~2,000–2,700 ft along Lisbon Valley fault - under-explored.
-
50+ drill holes of gamma-log data indicates uranium mineralization potential on the east side.
-
Targeting mirror-image mineralization style common in salt-anticline systems.
STRATEGIC OBJECTIVE
-
Systematically test the east belt extension for district-scale uranium discovery potential.

THE BIG INDIAN PROJECT
Overview
-
Mirror-image potential on salt anticlines
In systems like Lisbon Valley, structure-controlled fluids and permeable hosts commonly drive deposition on both flanks of an anticline—not just one.
-
What’s been mined
~78 Mlbs U₃O₈ were historically produced from the west side of the Lisbon Valley anticline at strong grades. The east side remains comparatively under-explored.
-
What's different about the east
The east flank is down-dropped along the Lisbon Valley fault—preserving prospective horizons and creating new structural traps where fluids can accumulate.
Our Thesis
Replicate the key controls that worked on the west—structure + permeable stratigraphy + reductant traps—to unlock mirror-image discovery potential on the east.
Why American Atomics
We’ve assembled the land, the data, and the capital plan to systematically test the highest-confidence corridors first.

KEY ADVANTAGES
-
Dominant land position
A contiguous claim block covering the vast majority of the east flank—positioned across the most prospective structural and stratigraphic belts.
-
Data-backed targets
Legacy gamma-log anomalies within priority horizons (e.g., Chinle base, upper Cutler) reinforce our east-side deposition model.
-
High-probability vectors
Anticline-parallel faults, relay ramps, fracture corridors, and redox boundaries that mirror west-side ore controls.
-
Catalyst-rich work plan
Rapid integration of logs and historical datasets into a 3D framework → targeted oriented HQ drilling on the best corridors → near-term discovery signals.

THE BIG INDIAN PROJECT
LISBON VALLEY
The American Atomics / Big Indian Prospectors block blankets the east side of the Lisbon Valley anticline, capturing the structural spine, major fault splays, access routes, and the stratigraphic hosts that powered 78 Mlbs of historic production on the west—now ready to be systematically tested on the east.
