The Lac Troilus Gold-Copper Deposit, Northwestern Quebec: A Possible
Bibliographic record
Abstract
The Lac Troilus gold-copper deposit is located approximately 120 km north of Chibouga-mau, Quebec, within the northeastern part of the Evans-Frotet greenstone belt, an Archcan, bimodal, supracrustal sequence of mafic to felsic volcanic flows and tuffs. Volcanic rocks in the vicinity of the deposit form an overturned sequence of porphyritic intermediate tuffs and flows and mafic lapilli tuffs. These rocks were intruded, post-tilting, by syn- to late tectonic felsite and feldspar porphyry dikes and sills. The bulk of the copper-gold mineralization is hosted within a zone of in situ breccia along the contact between the intermediate and mafic volcanic rocks. The Lac Troilus deposit has a drill-indicated geologic resource totaling ap-proximately 60 million metric tons containing over 2.5 million oz gold, 3 million oz silver, and 60,000 metric tons copper. Mineralization consists of 2 to 3 percent sulfides with localized areas of up to 7 percent sulfides. The sulfides are principally chalcopyrite, pyrite, and pyrrhotite, with rare sphaler-itc. The sulfides form disseminations, tiny veinlets, and narrow semimassive seams and are controlled by both foliation and fractures. Gold generally occurs as electrum, although native

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.
