The Latte Gold Zone, Kaminak's Coffee Gold Project, Yukon, Canada: Geology, Geochemistry, and Metallogeny
Bibliographic record
Abstract
The Latte Gold Zone is hosted within complexly tectonically imbricated metamorphic rocks of the Yukon-Tanana terrane. Snowcap assemblage psammitic schist and amphibolite with exotic Slide Mountain ultramafics overthrusts unidentified arc metavolcanics which in turn overthrust the Late Permian Sulphur Creek orthogneiss. Rapid unroofing of the Dawson Range during the Mid-Cretaceous culminated in dextral movement along the Coffee Creek fault system. A set of stacked, ESE–WNW trending, steeply dipping brittle fault structures served as conduits for gold-bearing fluids. Core-logging, detailed petrography, microprobe analysis, and PIMA investigations indicate that Latte is an epizonal orogenic gold deposit. Gold is hosted within arsenian pyrite in association with dolomite and illite, and was deposited by a CO2-H2O-As-Sb-S-Ag-Au fluid between 220 and 250° C which sulphidized metamorphic mica. Primary gold disseminations are locally remobilized by a CO2-rich fluid and re-deposited within arsenian pyrite in breccias and dolomite-quartz veinlets.

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.
