Abstract
Anthony Williams-Jones, a hydrothermal mineral deposit expert at McGill University, Quebec, told IM that the science and geology of China's rare earths deposits is limited, even in the case of the largest rare earths mine in the world, Bayan Obo, located in Inner Mongolia. Williams-Jones explained that the higher solubility of cerium and lanthanum at lower temperatures and higher pH values also facilitated the presence of heavy rare earth-biased mineralisation at sites like Northern Minerals Ltd's Browns Range project in Australia's Northern Territory. this instance, less soluble heavy rare earth elements were deposited at the project site, whereas cerium and lanthanum, among other light rare earths, remained mobile. The cerium and lanthanum ions simply pass onwards further away from the primary deposit, Williams-Jones told IM. In this regard, geochemical studies can identify the location of potential deposits, whereby lanthanum and cerium concentrations form a distal indicator, which will give way to heavier rare earths concentrations closer to the deposits.

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.
