Indicator mineral signatures of the Halfmile Lake Zn-Pb-Cu volcanogenic massive sulphide deposit, Bathurst, New Brunswick: part 2 - till data
Bibliographic record
Abstract
Till and bedrock samples were collected in 2007 and 2008 around the Halfmile Lake Zn-Pb-Cu VMS deposit, Bathurst Mining Camp, as part of the Geological Survey of Canada's Targeted Geoscience Initiative-3 (TGI-3) (2005-2010). This report describes one component of the study, which examined the indicator minerals in till samples around the deposit. The Halfmile Lake VMS deposit is capped by a preglacial gossan that formed by chemical weathering and oxidation during the late Pliocene. The mineralogical and geochemical signatures of the glacial dispersal train down-ice (east) of the deposit reflect this gossan, including secondary minerals goethite, beudantite, and jarosite in the till. Chalcopyrite, pyrite, gold, and cinnabar are also present in the till down-ice of the deposit. The Zn-spinel gahnite, which is known to be an indicator of VMS mineralization, is also present in the local till; however, its bedrock source is not yet known.

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.
