Abstract
Three prominent mineralized calc-silicate occurrences (Cr-rich skarn, Fe-rich skarn, and REE-enriched calc-silicates) are present in close association with regional planar structures at the White River property of LAC Minerals Ltd., in the Archean Hemlo-Heron Bay greenstone belt of the Superior province, Ontario, Canada. The Cr- and Fe-rich skarns were metasomat-ically derived, respectively, from ultramafic-mafic host rocks at 400 ø _+ 50øC, 3 kbars, and an aqueous fluid (Xco • (0.03), and mafic host rocks at 500 ø to 560øC, 4 kbars, and an aqueous fluid (Xco • (0.05). The REE-enriched calc-s•licates are characterized by abundant epidote-prehnite veins and minor REE-rich minerals and were formed at 3œ0øC and 1.7 kbars during infiltration of an aqueous fluid of moderate salinity. These three calc-silicate occurrences collectively indicate a protracted episode of skarn development which commenced immediately after the peak of the regional thermal metamorphism. Metallogenesis correlates strongly with the respective host lithologies and is characterized by Fe-Ni-Co-Zn-Cu-Mo sulfides in the Cr-rich skarn, similar to the assemblage of Outokumpu-type ores, and Fe-Zn-Cu-Ni-Co sulfides in the Fe-rich skarn, resembling sulfide ores in calcic

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.
