Abstract
Rick Shearer, CEO of Emerge Energy and Superior Silica said that the lower crude oil prices were having a chilling effect on the frac sand market, stating in March that Emerge Energy and its Superior Sands subsidiary would work with customers to help them lower their total cost of sand on a delivered cost per-tonne basis. Following disappointing 2014 financial results, frac sand producer Victory Nickel also felt the impact of falling demand as, in mid-April, it temporarily suspended production at its Seven Persons (7P) frac sand plant in Alberta, Canada, due to slower than anticipated frac sand sales. As a result of market uncertainty in Canada and the US, a knee jerk reaction by predominantly the US-based frac sand retailers caused import frac sand prices in Canada to be reduced to levels that do not appear to be sustainable over the long term, Victory Nickel outlined in a statement.

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.
