Abstract
Located in the Western Brooks Range of Alaska, the Red Dog Mine is one of the most northerly active, zinc-lead open pit mines. Mining of high grade zinc and lead sulphide ores results in the production of waste rock that is mostly acid generating. Control and treatment of acid rock drainage (ARD) from waste rock and pit walls is one of the most critical environmental activities at the mine site. The treatment of ARD water from the main waste rock stockpile, containing total dissolved solids (TDS) values as high as 90,000 mg/L, is expensive today and it will be a major component of post-closure costs in the future. In order to reduce the amount of water to be treated in the near and longer term, Red Dog has initiated programs to minimise the production of ARD at the source, through construction of engineered cover systems on waste rock stockpiles and will make improvements in the collection and treatment of the ARD waters from the stockpiles, to allow for more efficient removal of TDS from the impacted waters.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
