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

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
