Electrical conductivity mechanism and textures of mineralized sericite schist from the Gold Lake area of the Yellowknife mining district, Northwest Territories
Bibliographic record
Abstract
The electrical conductivity mechanisms have been determined for five subsamples taken from two mineralized schist samples collected from the Gold Lake area of the Yellowknife mining district, Northwest Territories. The samples were selected to characterize the resistivity of the alteration zone, determine the effect of crosscutting veins, and of fine-grained sulphide minerals oriented parallel to foliation. The purpose of this paper is to document, within the framework of the Yellowknife EXTECH-III Project, results of the laboratory electrical resistivity determinations for use in interpreting ground electromagnetic surveys which have been conducted in the Gold Lake area. Results indicate that high bulk electrical resistivity (?r) values are likely a result of poor sulphide grain connectivity and of fairly continuous quartz and calcite layers. The lower ?r values are due to good sulphide grain connectivity. Alteration visible in hand sample and in scanning electron microscope images suggest that the effect of some pore-fluid conductivity exists as well.

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.
