Geochemical anomalies in soils and uppermost siliciclastic units overlying the Phoenix uranium deposit, Athabasca Basin, Saskatchewan
Bibliographic record
Abstract
Many mineral deposits are concealed by younger rocks and unconsolidated glacial deposits, which make buried deposits difficult to explore using traditional exploration tools. Under the TGI4 program, this project is examining whether surficial geochemical anomalies exist for deeply buried uranium deposits. This study selected the Phoenix deposit on Denison Mines' Wheeler River Property, located in the southeastern Athabasca Basin, northern Saskatchewan. Discovered in 2008, the deposit currently has a National Instrument 43-101 indicated resource of approximately 40 million lbs U3O8. The uranium oxide minerals are localized within four pods termed the A, B, C and D ore zones. These pods are located mostly along the unconformity between the crystalline basement rocks and overlying Athabasca sandstone units, approximately 400 metres below the surface. The region is characterized by gently rolling hills comprising glacial till and moraines ranging in thickness from 30 to 50 m, with continuous permafrost. A total of 226 soil samples (humus, E-, B-, and C-horizon) were collected from 59 sites along 3 transects at approximately 10 metre intervals over the "A" and "B" ore zones. The extensive transects facilitated sampling of both "mineralized" and "background values" in the study area. Preliminary geochemical analyses of the samples revealed the presence of U, Mo, Co, Ag and W anomalies in humus, B-horizon soil and uppermost sandstone units overlying the ore zones and directly above the basement location of a nearby northeast-trending "WS Hanging Wall" shear zone. Concentrations in the surface media are up to 6 times background values for U, 5 times for Mo, 4 times for Co, 20 times for Ag and 18 times for W. The geochemical anomalies in the surface media and the uppermost sandstone units over the shear zone suggest that the fault has acted as a conduit for upward migration of fluids from the deposit. This preliminary study indicates that geochemical analysis of surface media is potentially an efficient and inexpensive exploration tool for detecting deep-seated uranium deposits.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
