Spectral induced polarization measurements of sericite schist and ore samples from the Yellowknife mining district, Northwest Territories
Bibliographic record
Abstract
Spectral induced polarization measurements have been performed over a frequency range of 1 10 6 Hz on a suite of four mineralized and nonmineralized rock samples from the Giant mine and Con mine areas of the Yellowknife mining district, Northwest Territories. The purpose was to provide data for use in determining the electrochemical characteristics of the sulphides in these rocks. Results indicate that the amplitude of complex resistivity (r + ) and imaginary resistivity (r² ) in thea -direction (per-pendicular to foliation) consistently display larger values than those of theb- org -directions (parallel to foliation). The per cent frequency effect displays similar trends in the two directions (a - andb -org -directions) with values in the range of 10 30% at the lower frequencies (< 1000 Hz). This implies that the induced polarization effect of the sulphide minerals are being reflected in the data for all of these samples.

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.
