Audio-magnetotelluric studies at the McArthur River mining camp and Shea Creek area, northern Saskatchewan
Bibliographic record
Abstract
Audio-magnetotelluric (AMT) data collected as part of the EXTECH IV project revealed the subsurface conductivity structure in the Shea Creek exploration area and the McArthur River uranium mining camp, northern Saskatchewan. The inversion of the McArthur River AMT data detects subsurface features to more than 500 mdepth related to basement graphitic conductors and faulting postdating Athabasca Group deposition, argillic alteration, fracturing, sulphide mineralization, and silicification of the overlying sandstone. The Shea Creek survey inversion results agree with what is known about the local geological setting in the regional sense; i.e. that the conductive feature corresponds to shallow westerly dipping sequences of graphite-rich Archean metasedimentary rocks. An analysis of synthetic responses generated from borehole resistivity logs collected in theMcArthurRiver area further substantiates that the audio-magnetotelluric technique is a useful surface investigative technique for delineating graphitic features in the basement and zones of silicification in the overlying siliciclastic sedimentary rocks.

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.
