Abstract
Better communications can enhance the mining industry's image among the wider community, the PDAC convention hears. Industrial minerals companies need to better manage their communications in an increasingly interconnected world, the chief executive officer of Brazil-based Nexa Resources told this year’s convention of the Prospectors and Developers Association of Canada (PDAC). In comments echoed by Canadian colleagues at the event in Toronto, Canada, March 4-7, Tito Martins said that the industry must change the way it engages with an expanding number of potential partners, from local communities and environmentalists through to regulators and financiers. And it needs to be ready to change such messaging quickly, if necessary, he added.

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.
