Abstract
During a search for the source of a quartzite glacial erratic carrying galena, newly published aeromagnetic maps attracted attention to an unsuspected metasedimentary series. Subsequent prospecting in this belt uncovered quartzite boulders containing finely-disseminated sphalerite together with minor galena, pyrite, and pyrrhotite. These boulders formed a glacial train some 10 miles in length flanked by pyrite-bearing quartzite boulders along a length of 40 miles. Samples of the sphalerite-bearing float assayed up to 14 % Zn and 4« % Pb. The surficial geology showed that the valley along which the float was found repre-sents a melt water channel that had exposed the boulders from the till. The source of the float was found to be at the east side of the southwest end of George Lake where bedrock was covered by drift ranging from 0-100 feet in thickness. Surface drilling indicated a deposit of 5 million tons averaging 2.65 % Zn and 0.35% Pb, which included a higher. grade core of 2.9 million tons averaging 3.67 % Zn and 0.53 % Pb. These 'estimated tonnages are based on shallow drilling and are assumed

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.
