A CO <sub>2</sub> –O <sub>2</sub> –light hydrocarbon–soil-gas anomaly above the Junction orogenic gold deposit: a potential, alternative exploration technique
Bibliographic record
Abstract
A soil-gas survey conducted above the Junction orogenic lode-gold deposit near Kambalda in Western Australia detected strong, broadly coincident, CO 2 –O 2 –light hydrocarbon anomalies through cover sediments above known mineralization. Alternatively, only CO 2 –O 2 aberrations (without light hydrocarbons) were detected above areas where non-gold related carbonate and sulphide mineralization exists. Oxidation of the alteration assemblage associated with mineralization and the release of the gases in the fluid inclusions they contain are proposed as the source for these CO 2 –O 2 –light hydrocarbon anomalies. We believe that soil-gas exploration for orogenic gold deposits has widespread potential as an exploration method in Western Australia where regolith cover can make detection of mineralized shear zones by traditional exploration methods for gold problematic to impossible.

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.
