Abstract
SummaryWe describe how the world-class Proterozoic Century zinc deposit in northwest Queensland has been sculptured by an Ordovician meteorite impact, the Lawn Hill Impact Structure. The deposit is located at the SW edge of the crater, is dismembered by crater-related faults and is overlain by breccias (suevite) related to fall-back and resurge processes into the crater. Using drilling and newly acquired IP data, we interpret a five-fold thickening of slumped Cambrian carbonate breccias in the crater, to a depth of 600 m. The Century deposit is known to have been larger than has been so far discovered. A restoration of the post-ore faults and Zn:Pb metal ratios of the mined Northern and Southern ore blocks, indicates an original enlarged form of the world-class deposit and that parts of the orebody may have spalled into the Cambrian-filled crater. This points to significant discovery potential in an otherwise intensely explored, near-mine setting.

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 it
