A new model for an old camp: the enigmatic Ag-Co-Ni-As-Bi mineralization of Cobalt, Ontario
Bibliographic record
Abstract
The recent emergence of Co as a critical metal used in a variety of high-technology industries has refocused exploration at Cobalt, Ontario. This district represents an unusual ore deposit-type termed the five-element (Ag-Ni-Co-As-Bi) assemblage and was important historically as Canada’s former premier Ag producer at over 460 Moz (1904-1989). This study applies a sophisticated analytical protocol consisting of whole rock analysis, petrography, and insitu mineral analyses (SEM-EDS, LA-ICP-MS) to a sample suite with spatial coverage across the district. These methods constrain geological controls on regional metal distribution, the sequence of alteration and mineralization, and the physiochemical evolution of the system. An updated genetic model for the mineralization involves the veins representing a district-scale homogeneous hydrothermal-metal melt system driven by contact metamorphism and partial melting of pre-existing sulfides in underlying Archean basement rocks. This model enhances understanding of deposit formation and offers refined geochemical vectors to aid ongoing exploration efforts.

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.
