3D magnetic inversion of mineral prospects in the Great Bear Magmatic Zone, Northwest Territories
Bibliographic record
Abstract
The Great Bear magmatic zone is a Paleoproterozoic continental magmatic arc in the Northwest Territories, Canada. Interpretation of aeromagnetic data shows the region to be associated with high-amplitude magnetic anomalies which are related to zones of iron oxide-alkali-altered rocks and polymetallic iron oxide-copper-gold deposits and prospects. Iron oxide-alkali-altered rocks in the field may be obscured by surficial cover and lakes, and surface exposures may not be representative of the extent and intensity of alteration. Therefore geophysical techniques are employed to investigate regional prospects across the variably exposed and inaccessible terrain. Three-dimensional magnetic inversion models are constructed for twelve of the prospects and deposits in order to investigate the scale, geometry and magnetic susceptibility of their highly magnetite-altered zones. The choice of model locations was guided by known mineral prospects, targets resulting from prior two-dimensional geophysical methods, and the extent of the associated magnetic anomalies.

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.
