Geochemistry results from the south Rae mapping project, Northwest Territories, 2015 and 2016 field seasons
Bibliographic record
Abstract
This study, a part of the GEM2 South Rae Mapping Project, was carried out during 2015 and 2016 in the southeastern portion of the Canadian Northwest Territories, in the area comprising the South Rae craton (NTS map sheets 75B, H, G, A). During the regional mapping four new radiometric anomalies were recognized and several locales of hydrothermal alteration were outlined. All the radiometric anomalies are located in the northeast (Gemelo showing) and southwest (Sarita, Hidden, Triple-X) portions of NTS 86B along the Black Bay fault. Regional geochemical assay samples were taken to investigate the metal signature of rocks at these locales and in potentially prospective samples throughout the study area. Here we report concentrations for major, trace, rare earth, and platinum group elements, and precious and base metals of 65 samples, including a number showing anomalous concentrations. We report the first ever showings in NTS 86B and G: new REE (Gemelo; 0.8 wt.% REE) showing. The Gemelo showing occurs near the northeastern terminus of the Black Bay fault. The geochemical results obtained from material collected at the southwest Black Bay fault radiometric anomalies show no particular U, Th and rare earth element enrichments.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
