Distribution of Platinum Group Elements in the New Afton Alkalic Cu-Au Porphyry Deposit, Kamloops, British Columbia
Bibliographic record
Abstract
New Afton is an alkalic Cu-Au porphyry deposit situated 10 km west of Kamloops, British Columbia, within the Quesnel island arc terrane, a Late Paleozoic to Mesozoic arc complex that occupies the eastern part of the Intermontane Belt of the Canadian Cordillera.Bulk rock and sulfide minerals from New Afton contain potentially economic concentrations of platinum group elements (PGE).Primary PGE (Pd ± Pt) enrichment occurs within the main Cu-Au ore body and is spatially associated with the Cherry Creek monzonite.Platinum group element mineralization occurs as both discrete platinum group minerals (PGM) and as trace components in nickeliferous pyrite.The early hydrothermal fluids that caused primary Cu-Au-PGE mineralization precipitated both Pd, transported as a HS -complex, and Ni during cooling and the formation of the main ore body.The initially deposited PGE were susceptible to subsequent hydrothermal re-mobilization and reprecipitation as platinum group minerals.
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.
