Abstract
The Oberon de Weber open pit is part of the Pinos Altos Mining Complex owned by Agnico Eagle Mines Ltd. in Mexico. A project was initiated in 2013 to enable the deposition of tailings in this soon-to-be exhausted pit while mining the underground portion of the deposit extending below the pit. A conceptual plan was proposed for constructing the tailings facility and mining the crown pillar below it. A series of investigations, preliminary and detailed studies, and a risk assessment were conducted to prepare a plan that was technically sound, safe, and environmentally secure during operations and after closure. Several alternatives were considered and analyzed to optimize the recovery of the high-grade ore. Economic and technical analyses supported the construction of an artificial crown pillar within a narrow trench excavated at the pit bottom, combined with a 10-m rock pillar above the underground stopes. This paper describes construction of the facility, water management, and instrumentation of the crown pillar. The Oberon de Weber Tailings Storage Facility has been in operation since the end of 2015 and is performing well. The crown pillar extraction has been successful, exceeding the planned resource recovery.

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
