Abstract
To increase the reserves of the possibly Carlin-like Dashui gold deposit in Maqu county, Gansu Province, central China, exploration techniques to detect mineralization in the subsurface of the mining district are required. Orebodies in the Dashui deposit are usually controlled by structures closely associated with the Ge'erkuohe granitoid. Samples collected from the deposit area indicate that the mineralization is primarily associated with the indicator elements, Au-Ag-As-Hg-Te-Sb, and less so with the indicator elements, K 2 O-Rb-F-Ba. The supra- and/or near-ore haloes are characterized by an As-Sb-Hg-Te-Au-Ag association and sub-ore haloes by a W-Mo-Bi-Co-Sc-Ni-V-Cd association. The primary geochemical haloes of the two main orebodies show that they were formed by up to three hydrothermal events. These results indicated that the two orebodies may extend downward to great depths, as was later confirmed by drilling down to depths of c. 3500–3400 m.

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
