Increase in Chinese exports weakens vanadium pentoxide prices in 2014
Bibliographic record
Abstract
Metal Bulletin 's ( MB ) pricing database indicates that vanadium V[subscript]2 O[subscript]5 prices held steady in 2014 until November, when selling values began to fall. MB 's prices for vanadium ore (pentoxide) (min 98% Europe), stand at between $3.75/lb ($8.25/kg) and $4.05/lb ($8.91/kg). Canada-based, Largo Resources Ltd has secured a Canadian dollar (C$) 12m ($9.4m*) bridging loan for its Maracas Menchen V[subscript]2 O[subscript]5 mine in Brazil, which commenced production in August 2014. VanadiumCorp's resource drew on data from several programmes, including government drilling in 1970, SOQUEM drilling in 1980, trenching and drilling by McKenzie Bay Resources from 1997 to 2002, and Apella Resources, which is now Vanadiumcorp in 2013.

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.
