A calibrated engine that reads decades of legacy oil-&-gas gamma logs and tells you where the uranium is - before the first new hole.
The down-dropped east flank of the Lisbon Valley anticline was drilled for oil and gas, not uranium - yet the gamma tools ran anyway, recording a strong radiometric story across 50+ holes. That signal has sat dormant in dusty log files for decades. Conventional exploration ignores it and pays to re-drill blind.
Greenfield uranium programs spend their first dollars proving geology that legacy logs already constrain - burning capital before a single confirmation hole.
Raw API counts are distorted by casing, borehole size, mud weight, host lithology and radioactive-daughter disequilibrium. Uncorrected readings mislead.
Without a ranked, budget-bounded target list, programs over-drill weak ground and under-drill the anomalies that actually matter.
Gamma Engine is a live, auditable conversion engine. It translates historic gamma readings into an equivalent-uranium estimate (eU₃O₈), calibrated to recognised DOE standards, then plans the lowest-cost drill campaign to confirm it. Every number is computed from the engine's own API - asserted by nobody, recomputed in front of you.
Adjust a reading and the conversion recomputes against the running engine.
Total gamma (API), host formation, borehole diameter, mud weight and casing state are entered from the legacy log header.
Background lithology subtraction plus borehole, mud and steel-casing corrections isolate the net anomaly in × background.
Net-API maps to eU (ppm) via the DOE-GJ calibration, then to an eU₃O₈ percentage - a pre-assay estimate, never a claimed assay.
"Monetise every metre, misdrill nothing." Ranks twin-drill targets and fits the highest-priority metres inside a budget.
Holes are ranked by anomaly strength and confidence; the optimiser packs as many high-priority metres as a budget and cost-per-metre allow, twin-drilling the strongest legacy holes first.
eU₃O₈ is a pre-assay estimate - only chemical assay of core resolves true grade. That is exactly the calibration step after the first confirmation holes.
Western utilities and governments are racing to re-shore the nuclear fuel cycle. Domestic U.S. uranium - especially in proven districts like the Colorado Plateau and Lisbon Valley - moves from stranded to strategic. Gamma Engine sits exactly where capital wants confidence fastest: turning sunk historic data into a confirmable, low-cost path to resource.
Gamma Engine is American Atomics' own decision and disclosure layer - built to de-risk capital allocation internally and to demonstrate technical rigour to investors and partners. The model below is illustrative of how the engine creates and protects value.
| Track | What it does | Value created |
|---|---|---|
| Internal de-risking | Prioritises spend before the program starts | capital efficiency |
| Investor data room | Computed, calibrated, uncertainty-honest evidence | cost of capital |
| Drill optimiser | Budget-bounded twin-drill targeting | metres → confirmation |
| Engine-as-method | Repeatable across legacy-logged districts | portfolio leverage |

Every bar and number comes straight from the engine's API. Move an input, watch it recompute - nothing is hand-waved into the deck.

A dedicated control shows how daughter/parent imbalance moves the estimate - the key, often-ignored risk in salt-anticline uranium.
eU₃O₈ is explicitly pre-assay until core confirms it. Credibility comes from naming the limit, then planning the holes that resolve it.
Background lithology subtraction → borehole-diameter and mud-weight correction → steel-casing attenuation → net-API to eU (ppm) via DOE-GJ calibration → eU₃O₈ with a disequilibrium factor applied. Each stage is inspectable, not a black box.
A budget-constrained ranking that scores legacy holes by anomaly strength and confidence, then packs the highest-priority metres under a spend ceiling and cost-per-metre - twin-drilling the strongest targets first.
American Atomics is a uranium exploration and development company advancing the Big Indian project in Lisbon Valley, Utah - one of the most prolific uranium districts in the United States. Gamma Engine is the company's data-first method for converting a basin's worth of historic logs into a disciplined, confirmable path to resource.
