Abstract

fetched live from OpenAlex

Nemaska's core, 100% owned asset -- the Whabouchi lithium project in Quebec -- contains 27.3m tonnes proven and probable reserves at an average grade of 1.46% Li[subscript]2 O, held within the spodumene-bearing pegmatite intrusive dyke swarm. The project's claims cover 17.16 km[superscript]2. Nemaska is a Cree word meaning abundance of fish, revealing the native Canadian heritage of the project's location in Quebec. Accordingly, Nemaska has signed an impact benefit agreement (IBA) with the local First Nation and the Cree Nation Government, and thus does not anticipate any significant local objection to the project. Nemaska notes that Tesla currently uses lithium hydroxide in its battery packs, and estimates that at production levels of 500,000 vehicles per annum, around 28,000 tpa extra lithium hydroxide capacity will be needed by the Tesla plant.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
