Discrimination of elemental assemblages in the alteration halo of the Phoenix Deposit, Saskatchewan, through applied GIS
Bibliographic record
Abstract
This study was initiated as part of the TGI-4 uranium ore systems project to evaluate the dispersion of ore-related elements that could be used to increase exploration effectiveness for deeply buried, unconformity-related uranium mineralization. The Phoenix deposit, located in the Athabasca Basin, currently has indicated resources of approximately 52.3 million lbs U3O8. The mineralization consists of four pods termed the A, B, C and D ore zones at ca. 400 meters depth. The pods occur both at the unconformity and within the basement as steeply dipping zones associated with a fault zone termed the WS shear. The siliciclastic sandstones of the Athabasca Group overlying the Phoenix deposit are characterized by elevated enrichments in the elements Y, W, B, Mg, As, Pb, B, Co and Cu. Preliminary geochemical analyses of sandstone samples from the Manitou Falls Formation indicate a clear migration of Y and W in vertical columns while B, MgO and As data reveal zones of elevated values that extend from the ore zones to upwards of 350m above the deposit and 2.4 km along strike. Away from these chimneys, values of MgO, B, and As are comparable to that of regional outcrop and drillhole data, suggesting localized, well-defined enrichment of these elements in the vicinity of Phoenix. The abundance of other elements elevated in the orebody, such as Ni, Li and V, show little spatial relationship to mineralization in the overlying sandstones. These preliminary results illustrate that certain elements can play a guiding role in the exploration of unconformity-related uranium deposits.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
