copper prospect, southwestern Yukon
Bibliographic record
Abstract
The Sato prospect is located between Aishihik Lake and Long Lake in southwestern Yukon Territory. Low grade porphyry-style copper mineralization was discovered on the property in 1969. The main country rock in the study area is a potassium feldspar megacrystic granite that is correlated with the Early Jurassic Aishihik and/or Long Lake plutonic suite. Mineralization on the property is hosted by a multiphase intrusive complex that is thought to represent a high level intrusive member of the Late Cretaceous Mount Creedon volcanic suite. The complex consists of three distinct phases, medium-grained diorite; coarse-grained diorite; and porphyritic quartz monzodiorite. U-Pb zircon dating of the medium-grained diorite and porphyritic quartz monzodiorite phases gives ages of 78.2 – 0.1 Ma and 78.8 – 0.2 Ma, respectively, which supports the correlation with the Mount Creedon Volcanic Suite. Four alteration zones are recognized on the property. Alteration is mainly developed in the medium-grained diorite and quartz monzodiorite phases. In order of decreasing intensity, these zones include potassic, phyllic, albitic, and propylitic. Copper mineralization consists of chalcopyrite, which occurs as a replacement of earlier-formed magnetite in the potassic and phyllic zones, and malachite which occurs on weathered fracture surfaces.

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.
