Electrical resistivity stability characteristics of water used to saturate rocks from Giant and Con mines, Yellowknife, Northwest Territories
Bibliographic record
Abstract
Differences in petrophysical properties (e.g. porosity and electrical resistivity) were noted between similar rock types from Giant and Con mines in the Yellowknife mining district (Northwest Territories). For example, the time required for resistivity of the rock samples to stabilize after pore-water saturation was considerably longer for Giant mine samples compared to Con mine samples. An exploratory study was initiated to find an explanation for these differences. This involved monitoring the resistivity of water used to immerse samples from the two mines, over a period of 340 hours, after vacuum saturation. Results indicate that considerable differences existed between the resistivity-time curves of the water in which the samples (sericite schist and basalt) from the mines were immersed. The resistivity of the water containing Giant mine samples was consistently higher and required considerably longer time to stabilize, compared to the Con mine samples. These differences are consistent with the differences in the sample porosity and electrical resistivity.

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.
