Silver Mineralogy and Modes of Occurrence at the Silver Hart Deposit, South East Yukon.
Bibliographic record
Abstract
The Silver Hart property is a high grade silver-lead-zinc deposit consisting of polymetallic vein style, manto (carbonate replacement) style, and skarn type mineralization. Host rock consists of calcareous and non-calcareous sediments of the Cassiar Platform, mainly biotite schists, limestone units, and the monzogranite unit of the Cassiar Batholith. Bulk geochemistry shows that silver concentrations are closely related to copper and antimony values, suggesting freibergite, a silver-rich endmember of tetrahedrite, is the dominant silver mineral. EPMA (microprobe) analyses identified 6 silver minerals present; silver-bearing anglesite, freibergite, diaphorite, stephanite, pyrargyrite, and silver substitution in galena. Sulfur isotope analyses of galena gave an average δ34S of 6.9‰ vs VCDT, indicating a mixed mineralizing fluid source. Metal zoning patterns indicates that there is a thermal gradient across the main vein from hottest in the south-west, above the monzogranite intrusion, to coolest in the north-east. Microprobe analyses of freibergite indicates initial ore-forming fluid temperatures were between 250°C - 350°C, with subsequent cooler mineralization fluids of 170°C - 200°C.

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.
