Investor Portal

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 historical 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.

Mirror-image potential on salt anticlines

Historically in salt anticlines you get equal deposition on both flanks of the formation. This means there should be a mirror deposit on the east flank of similar size and grade to the past produced West flank.
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 relatively under explored. Why? Because it sits 2,000ft deeper.
What's different about the east now

We have extensive gamma logs from prior O&G drillers down to 6,000ft through the target area of uranium mineralization. These logs show up to 10-12x background radiation. Something material is causing that. We believe it’s a uranium deposit.

Our Thesis

We intend to twin drill the existing O&G holes to prove the gamma anomalies are from the long suspected eastern flank deposit.

Why American Atomics

We’ve assembled the land, the data, and the capital plan to systematically test the highest-confidence corridors first.

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 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.
